(MUSIC PLAYING)
2
00:00:31,365 --> 00:00:34,693
NARRATOR: Our oceans are
the lifeblood of our planet.
3
00:00:40,832 --> 00:00:44,211
My grandfather, Jacques Cousteau,
inspired the world
4
00:00:44,613 --> 00:00:47,756
through his exploration,
sharing the mysteries
5
00:00:47,965 --> 00:00:50,765
of one of Earth's most important habitats.
6
00:01:10,821 --> 00:01:14,597
It was in that spirit that a team
of Disneynature filmmakers
7
00:01:14,658 --> 00:01:18,498
embarked on a quest to shed new light
on this hidden world...
8
00:01:18,787 --> 00:01:20,247
(INDISTINCT)
9
00:01:23,667 --> 00:01:26,563
...and on one
of its most enchanting inhabitants.
10
00:01:26,587 --> 00:01:28,589
(WHISTLING)
11
00:01:30,382 --> 00:01:35,246
NARRATOR: For wildlife filmmakers,
the ocean presents the greatest challenge.
12
00:01:35,372 --> 00:01:37,197
It is unforgiving.
13
00:01:40,976 --> 00:01:43,709
And visits beneath the waves
are fleeting.
14
00:01:50,485 --> 00:01:54,906
Here, they will enter a realm
where they are not the masters.
15
00:02:00,287 --> 00:02:03,087
And they must be respectful of the locals.
16
00:02:03,540 --> 00:02:05,220
MAN: No, no, no, no, no!
17
00:02:06,752 --> 00:02:08,112
(DOLPHINS CLICKS)
18
00:02:08,337 --> 00:02:10,270
NARRATOR: The team's mission?
19
00:02:10,714 --> 00:02:12,900
To reveal what it's like to live...
20
00:02:12,924 --> 00:02:15,824
- (DOLPHIN SQUEALS)
- ...in a dolphin's world.
21
00:02:23,060 --> 00:02:27,064
In the Red Sea,
wildlife cinematographer, Roger Horrocks,
22
00:02:27,230 --> 00:02:30,686
is preparing to film
the main character of our story...
23
00:02:31,318 --> 00:02:32,918
bottlenose dolphins.
24
00:02:33,654 --> 00:02:36,299
He has filmed dolphins all over the world,
25
00:02:36,323 --> 00:02:39,056
but it's his first time in this location.
26
00:02:39,951 --> 00:02:43,830
The key to his success
lies with scientist, Angela Ziltener.
27
00:02:44,623 --> 00:02:47,226
Having studied them here
for over a decade,
28
00:02:47,250 --> 00:02:50,514
she is a virtual gatekeeper
to the Red Sea dolphins.
29
00:02:50,796 --> 00:02:53,524
Certainly, the dolphins are
probably one of the most
30
00:02:53,548 --> 00:02:55,568
charismatic animals
that you do get in the ocean.
31
00:02:55,592 --> 00:02:57,820
They're mammals,
people can relate to them.
32
00:02:57,844 --> 00:03:01,532
Um, they're very, you know,
they have a mammalian consciousness.
33
00:03:01,556 --> 00:03:04,351
So, we have a kinship with them.
34
00:03:06,812 --> 00:03:09,123
NARRATOR:
As a highly experienced free-diver,
35
00:03:09,147 --> 00:03:13,691
Roger certainly has the athleticism
to keep up with dolphins underwater.
36
00:03:14,027 --> 00:03:16,255
ROGER: Filming dolphins
is probably the most physical
37
00:03:16,279 --> 00:03:19,676
- because they are incessantly on the move.
- (SPEAKING INDISTINCTLY)
38
00:03:19,700 --> 00:03:23,012
So, the biggest challenge
is really just keeping up with them
39
00:03:23,036 --> 00:03:27,249
and coming across those moments
of pure, beautiful interaction.
40
00:03:31,002 --> 00:03:33,147
It was massively helpful to have Angela,
41
00:03:33,171 --> 00:03:36,947
who has spent an incredible amount of time
in that location.
42
00:03:37,344 --> 00:03:40,352
Her knowing the dolphins
helped us tremendously.
43
00:03:41,430 --> 00:03:44,450
NARRATOR: Angela is
one of the few scientists in the world
44
00:03:44,474 --> 00:03:46,674
who studies them by scuba diving.
45
00:03:48,520 --> 00:03:52,816
It has allowed her to get to know
over 200 individual dolphins,
46
00:03:53,066 --> 00:03:55,962
- and allowed them to get to know her.
- (DOLPHINS WHISTLE)
47
00:03:55,986 --> 00:04:00,466
ANGELA: To understand the animals,
you actually have to be one of them.
48
00:04:00,642 --> 00:04:03,542
That means not that you are
the animal itself,
49
00:04:03,812 --> 00:04:06,412
but that you are accepted in the group.
50
00:04:07,247 --> 00:04:12,294
You will actually see all the individuals
and that every dolphin is different.
51
00:04:13,295 --> 00:04:16,631
Every dolphin has their own personality,
like humans.
52
00:04:17,632 --> 00:04:20,027
- (DOLPHINS WHISTLE)
- NARRATOR: The pod knows Angela,
53
00:04:20,051 --> 00:04:23,823
but will the dolphins accept
our strange new cinematographer?
54
00:04:23,847 --> 00:04:27,168
ROGER: I, kind of, knew
literally from the moment that I got in
55
00:04:27,192 --> 00:04:29,459
that this was a great opportunity.
56
00:04:29,728 --> 00:04:33,607
When those dolphins
were absolutely keen to interact,
57
00:04:33,815 --> 00:04:36,294
not only with each other,
but also with me as a cameraman...
58
00:04:36,318 --> 00:04:39,646
- (DOLPHIN WHISTLE)
- ...so that was just such a joy.
59
00:04:40,155 --> 00:04:43,867
Wild animals actually wanting
to be filmed. It was amazing.
60
00:04:47,704 --> 00:04:49,064
(DOLPHIN SQUEALS)
61
00:04:54,836 --> 00:04:56,647
ROGER: The more we film,
the more we got a sense
62
00:04:56,671 --> 00:04:58,671
of how they operate as groups.
63
00:04:59,299 --> 00:05:02,528
You know, one thing that was very,
very marked for me
64
00:05:02,552 --> 00:05:05,764
was the degree of interaction
between the dolphins.
65
00:05:06,598 --> 00:05:09,893
It was astounding to see
how tactile they were.
66
00:05:10,143 --> 00:05:11,823
(SQUEALING CONTINUES)
67
00:05:11,853 --> 00:05:14,415
ROGER: Dolphins spent time fin rubbing,
68
00:05:14,439 --> 00:05:17,339
and touching each other,
grooming each other.
69
00:05:17,442 --> 00:05:20,254
I thought initially
it was maybe a romantic thing,
70
00:05:20,278 --> 00:05:22,611
but actually, it's a bonding thing.
71
00:05:23,240 --> 00:05:26,326
They are emotional,
highly intelligent creatures,
72
00:05:26,535 --> 00:05:29,991
- very, very similar to us.
- (WHISTLING AND SQUEAKING)
73
00:05:30,497 --> 00:05:34,060
NARRATOR: And it wasnt long
before Roger spotted another example
74
00:05:34,084 --> 00:05:36,084
of their playful intelligence.
75
00:05:39,005 --> 00:05:43,677
ROGER: A group of juveniles just came in
and they were almost showing off.
76
00:05:43,927 --> 00:05:47,949
I remember that feeling of knowing
this is a unique piece of behavior
77
00:05:47,973 --> 00:05:51,109
and probably never going to get
this chance again.
78
00:05:51,476 --> 00:05:54,676
NARRATOR:
They flick their fluke to clear the sand,
79
00:05:54,729 --> 00:05:57,107
exposing a piece of coral.
80
00:05:58,483 --> 00:06:01,862
And voilà, a toy is born.
81
00:06:12,414 --> 00:06:15,876
Few animals spend so much time playing,
82
00:06:16,609 --> 00:06:18,312
yet this perceived playfulness
83
00:06:18,336 --> 00:06:21,148
might also be one of the ways
that young dolphins
84
00:06:21,172 --> 00:06:24,372
- practice their hunting skills.
- (DOLPHIN CLICKS)
85
00:06:28,805 --> 00:06:31,033
ROGER: You can just, kind of,
see that intelligence
86
00:06:31,057 --> 00:06:33,286
and that mischievousness
about them,
87
00:06:33,310 --> 00:06:38,732
and again, just such an incredible insight
into how intelligent these animals are.
88
00:06:42,903 --> 00:06:45,756
I think dolphins just do it
because they absolutely love it,
89
00:06:45,780 --> 00:06:48,580
and they enjoy the skill
and the challenge.
90
00:06:52,871 --> 00:06:55,671
I think they do it
for the sheer fun of it.
91
00:07:07,677 --> 00:07:11,824
NARRATOR: Angela's research has revealed
another aspect of dolphin life
92
00:07:11,848 --> 00:07:13,915
rarely witnessed in the wild...
93
00:07:15,018 --> 00:07:16,102
sleeping.
94
00:07:19,064 --> 00:07:22,392
This group of dolphins
is so relaxed in her presence,
95
00:07:22,984 --> 00:07:25,184
they take a nap as she watches...
96
00:07:27,656 --> 00:07:28,936
and Roger films.
97
00:07:34,120 --> 00:07:37,256
Dolphins sleep
with just half the brain at a time.
98
00:07:38,625 --> 00:07:42,785
Half the brain needs to be awake
to remember to surf as to breathe
99
00:07:43,046 --> 00:07:45,632
and to keep an eye out for any danger.
100
00:07:47,634 --> 00:07:50,679
As a consequence
of having such active brains,
101
00:07:50,971 --> 00:07:55,350
wild dolphins, just like us,
need lots of sleep.
102
00:07:57,644 --> 00:08:00,464
ROGER: They do these beautiful movements,
synchronized movements where they
103
00:08:00,488 --> 00:08:02,888
come up and they go back down again.
104
00:08:03,566 --> 00:08:07,112
It's very, you know, very soporific,
very slow.
105
00:08:08,154 --> 00:08:10,421
Really, really beautiful to watch.
106
00:08:12,701 --> 00:08:14,381
It just felt very poetic.
107
00:08:23,628 --> 00:08:26,509
NARRATOR: Thanks to Angela,
Roger and the team
108
00:08:26,533 --> 00:08:30,927
are starting to get a taste
of what it's like to be a wild dolphin.
109
00:08:32,095 --> 00:08:36,703
Knowledge they will need to build on,
in the next leg of their adventure.
110
00:08:38,893 --> 00:08:43,440
It was just an absolute privilege
to be... to have that kind of access
111
00:08:43,606 --> 00:08:48,462
to, you know, these animals on their terms
because they choose to be with you.
112
00:08:48,486 --> 00:08:51,132
You know, you can't force them
to be with you, and I think,
113
00:08:51,156 --> 00:08:53,801
you know, of all the locations I've dived,
114
00:08:53,825 --> 00:08:55,594
they were the most welcoming,
115
00:08:55,618 --> 00:08:59,458
um, and that was, you know,
something that I'll never forget.
116
00:09:01,708 --> 00:09:04,937
NARRATOR:
Roger has made filming dolphins look easy,
117
00:09:04,961 --> 00:09:09,313
but will cinematographer, Didier Noirot,
have the same luck in Hawaii
118
00:09:09,507 --> 00:09:12,407
filming the next main characters
of our story?
119
00:09:15,680 --> 00:09:16,973
Humpback whales.
120
00:09:21,352 --> 00:09:25,023
Hawaii is a very good location to film
humpback whales...
121
00:09:26,066 --> 00:09:28,401
because of the whale population.
122
00:09:28,860 --> 00:09:31,547
- DIDIER: You're sure to see whales there.
- (SPRAYS WATER)
123
00:09:31,571 --> 00:09:35,923
DIDIER: Crystal clear water,
so, that's perfect place to film whales.
124
00:09:36,951 --> 00:09:42,135
NARRATOR: It is also here that every year,
the females give birth to their calves.
125
00:09:44,125 --> 00:09:47,581
And filming a mother and calf
is the team's first task.
126
00:09:49,756 --> 00:09:52,223
They set out aboard the Luckey Strike
127
00:09:52,759 --> 00:09:54,439
where skipper Tad Luckey
128
00:09:54,719 --> 00:09:58,047
and a group of scientists
led by Professor Joe Mobley
129
00:09:58,389 --> 00:10:01,781
are their best chance
for locating these family pairs.
130
00:10:02,602 --> 00:10:04,538
This is always a big challenge.
131
00:10:04,562 --> 00:10:07,462
You don't know what you get,
never in advance.
132
00:10:07,565 --> 00:10:09,565
These whales are so difficult.
133
00:10:09,901 --> 00:10:13,655
It's very tricky for the producer, I mean.
(CHUCKLES)
134
00:10:14,948 --> 00:10:18,094
NARRATOR: Finding a whale in Hawaii
is not that hard,
135
00:10:18,118 --> 00:10:20,985
but skipper Tad
has to find the right whale,
136
00:10:21,454 --> 00:10:23,134
and that's the challenge.
137
00:10:23,665 --> 00:10:26,793
DIDIER: To find the right whale to film,
138
00:10:27,377 --> 00:10:30,880
especially mom and calf,
I have no expectation.
139
00:10:31,339 --> 00:10:35,510
That means I never know
what I'm going to get on camera.
140
00:10:37,720 --> 00:10:41,816
NARRATOR: As part of Jacques Cousteau's
original expedition team,
141
00:10:41,891 --> 00:10:45,812
Didier has over 30 years' experience
filming whales.
142
00:10:46,771 --> 00:10:47,897
I have 200.
143
00:10:48,690 --> 00:10:52,146
NARRATOR: But each opportunity
is always unpredictable.
144
00:10:54,487 --> 00:10:56,489
Come on. Come on.
145
00:10:58,482 --> 00:11:00,682
NARRATOR: It is a mother and calf
146
00:11:01,327 --> 00:11:05,679
but will Mom accept Didier
as easily as the dolphins warmed to Roger?
147
00:11:06,666 --> 00:11:07,709
You can try.
148
00:11:08,668 --> 00:11:10,173
Go ahead.
149
00:11:11,004 --> 00:11:13,816
DIDIER: The difficult thing to film
when you film mother and calf
150
00:11:13,840 --> 00:11:17,719
is to get close, silently,
as close as you get.
151
00:11:18,636 --> 00:11:22,056
NARRATOR:
He uses a bubble-free rebreather apparatus
152
00:11:22,432 --> 00:11:24,112
to silently approach.
153
00:11:28,646 --> 00:11:32,806
And any whale that doesn't accept
Didier's presence is left alone.
154
00:11:36,889 --> 00:11:39,489
The team needs to find a friendly whale
155
00:11:39,782 --> 00:11:42,115
that is comfortable around a diver.
156
00:11:45,205 --> 00:11:46,289
(GROANS)
157
00:11:47,081 --> 00:11:48,761
Well, they just left.
158
00:11:48,917 --> 00:11:51,878
We were ready to go, but now they are far.
159
00:11:53,630 --> 00:11:56,984
NARRATOR: But attempts to film
another mom and calf...
160
00:11:57,008 --> 00:11:58,688
produced the same result.
161
00:11:58,885 --> 00:12:02,907
DIDIER: When you see mother and calf,
the mother is always very aware.
162
00:12:02,931 --> 00:12:06,476
She's protecting the calf,
so any unknown thing
163
00:12:06,643 --> 00:12:09,354
like me would make her alert.
164
00:12:10,313 --> 00:12:11,993
Take two for nothing.
165
00:12:15,652 --> 00:12:17,785
NARRATOR: Another one gets away.
166
00:12:18,780 --> 00:12:22,300
- The mom and calf left.
- WOMAN: You have nothing, huh?
167
00:12:26,621 --> 00:12:27,622
Go.
168
00:12:33,553 --> 00:12:36,453
NARRATOR:
Didier is becoming all too familiar
169
00:12:36,506 --> 00:12:38,906
with the backsides of mother whales.
170
00:12:44,681 --> 00:12:47,081
DIDIER: So, you have to keep trying,
171
00:12:47,267 --> 00:12:52,188
finding a whale, new whale,
and one that lets you come close.
172
00:12:59,612 --> 00:13:02,532
NARRATOR:
After a long, unsuccessful day,
173
00:13:02,949 --> 00:13:05,243
he makes one last attempt.
174
00:13:05,603 --> 00:13:08,403
DIDIER:
By the way, this is the ninth time.
175
00:13:10,915 --> 00:13:13,115
NARRATOR: Then, a stroke of luck.
176
00:13:13,376 --> 00:13:17,213
Didier has found a playful,
approachable calf.
177
00:13:17,547 --> 00:13:21,694
DIDIER: You don't dive and go straight
for the mom with the calf underneath.
178
00:13:21,718 --> 00:13:24,618
You first have to make friends
with the calf.
179
00:13:25,013 --> 00:13:28,951
If the calf stays around you,
that he is not scared, then turns around,
180
00:13:28,975 --> 00:13:32,175
the whale will know down there,
even if she sleeps,
181
00:13:32,270 --> 00:13:34,665
you know, she knows that there is someone,
182
00:13:34,689 --> 00:13:37,825
but she knows the calf is happy
with this someone,
183
00:13:38,109 --> 00:13:40,028
so she may tolerate that.
184
00:13:44,532 --> 00:13:48,012
NARRATOR: And as it dives back
under its mother to rest,
185
00:13:48,036 --> 00:13:51,414
- Didier follows quietly.
- (WHALE SINGS)
186
00:13:51,664 --> 00:13:55,269
DIDIER: Now is the time,
because maybe after the whale will leave,
187
00:13:55,293 --> 00:13:58,004
and I will lose her for good.
188
00:13:58,296 --> 00:14:01,632
So, I decided to swim very, very slowly,
189
00:14:02,091 --> 00:14:05,094
and without making any noise at all.
190
00:14:10,266 --> 00:14:12,661
NARRATOR: Mom watches him carefully,
191
00:14:12,685 --> 00:14:15,585
but she seems content
with him alongside her.
192
00:14:18,066 --> 00:14:20,151
Finally, success.
193
00:14:22,236 --> 00:14:23,916
Divers like Didier...
194
00:14:23,946 --> 00:14:27,950
are just humble visitors
in this vast undersea world...
195
00:14:29,619 --> 00:14:32,097
but even the most powerful of creatures
196
00:14:32,121 --> 00:14:35,021
will sometimes allow you
to get close to them.
197
00:14:38,127 --> 00:14:39,962
After weeks of persistence,
198
00:14:40,254 --> 00:14:44,050
the team finally succeeded in filming
a mother and calf.
199
00:14:45,593 --> 00:14:49,931
This mother's duty is to protect her calf
while it grows quickly,
200
00:14:50,264 --> 00:14:54,104
before the long migration
back to Arctic waters.
201
00:14:54,352 --> 00:14:56,819
As they travel between resting spots,
202
00:14:56,979 --> 00:15:00,775
the mother encourages her calf
to breach repeatedly.
203
00:15:08,116 --> 00:15:11,060
It may look like just some fun
splashing about,
204
00:15:11,317 --> 00:15:15,623
but it's key to helping the young calf
build strength and muscles,
205
00:15:16,217 --> 00:15:19,353
that also develops
their breath-holding abilities.
206
00:15:34,267 --> 00:15:37,403
The close bond
between a mother whale and her calf
207
00:15:37,562 --> 00:15:40,481
provide our filmmakers
with their first inroad
208
00:15:40,690 --> 00:15:42,650
into humpback whale society.
209
00:15:44,986 --> 00:15:47,994
Shallow coastal waters
are the perfect sanctuary
210
00:15:48,406 --> 00:15:51,273
for a young calf
to grow healthy and strong.
211
00:15:52,160 --> 00:15:55,455
Away from the dangers
found in deeper, open waters.
212
00:15:59,542 --> 00:16:02,486
But it is also where it will soon
be introduced
213
00:16:02,587 --> 00:16:04,520
to a greater whale community,
214
00:16:05,173 --> 00:16:06,773
a complex society...
215
00:16:07,800 --> 00:16:11,429
one our team
is just beginning to understand.
216
00:16:16,684 --> 00:16:19,351
To truly understand a dolphin's world...
217
00:16:20,062 --> 00:16:24,414
the filmmakers need to journey
to the very heart of their ocean home.
218
00:16:26,235 --> 00:16:28,768
To the foundations of the whole story.
219
00:16:29,697 --> 00:16:32,033
A delicately balanced ecosystem...
220
00:16:32,783 --> 00:16:36,943
that is sanctuary to millions
of incredible supporting characters.
221
00:16:38,706 --> 00:16:40,166
A coral reef.
222
00:16:41,918 --> 00:16:45,054
Capturing the intricacies
of this underwater world
223
00:16:45,338 --> 00:16:48,282
requires a great deal
of technical camera skill
224
00:16:48,633 --> 00:16:51,969
and an exceptional eye
for precision and detail.
225
00:16:54,180 --> 00:16:58,532
Cinematographer, Doug Anderson,
is the perfect choice for such a job.
226
00:16:59,810 --> 00:17:02,498
DOUG: We wanted to make that experience
of viewing the reef
227
00:17:02,522 --> 00:17:04,082
as immersive as possible.
228
00:17:04,106 --> 00:17:05,792
So, we tried different techniques...
229
00:17:05,816 --> 00:17:08,337
(CHUCKLES) ...as many things
as we could think of
230
00:17:08,361 --> 00:17:11,489
to try and get
more engaging photography.
231
00:17:13,908 --> 00:17:15,594
Uh, we used this underwater scooter,
232
00:17:15,618 --> 00:17:18,562
which is like a torpedo
with a propeller on it,
233
00:17:18,871 --> 00:17:22,775
to get that feeling of the dolphin
like gliding over the reef.
234
00:17:29,340 --> 00:17:32,277
We used a jib, which is like a camera
on the end of an arm,
235
00:17:32,301 --> 00:17:34,863
which allowed us to make
for very stable tracking moves
236
00:17:34,887 --> 00:17:37,366
over the coral reef,
and really try and bring
237
00:17:37,390 --> 00:17:41,811
the character of the individual species
that we wanted to include
238
00:17:42,178 --> 00:17:43,298
to the screen.
239
00:17:50,987 --> 00:17:53,901
Of all the underwater habitats
on the planet,
240
00:17:54,156 --> 00:17:57,356
it's coral reefs
that are the most overtly diverse.
241
00:17:58,494 --> 00:18:03,874
Just amazed by the color, and the life,
and beauty in front of me.
242
00:18:05,124 --> 00:18:07,924
Absolutely breathtaking when you're there.
243
00:18:10,131 --> 00:18:12,508
Intense experiences of life.
244
00:18:21,851 --> 00:18:24,987
I like to think of a coral reef
a bit like a city.
245
00:18:25,754 --> 00:18:27,829
The buildings are the corals.
246
00:18:30,401 --> 00:18:35,406
Those buildings provide homes
and habitat for countless animals.
247
00:18:37,642 --> 00:18:40,762
Every animal that lives there
is as important to each other
248
00:18:40,786 --> 00:18:42,066
as the next one.
249
00:18:43,497 --> 00:18:46,226
But there are very obvious animals
in the coral reef
250
00:18:46,250 --> 00:18:48,117
that do very important jobs.
251
00:18:51,881 --> 00:18:55,235
NARRATOR: Doug wants to find
key characters like these...
252
00:18:55,259 --> 00:18:58,159
to highlight critical links
in the community.
253
00:18:59,135 --> 00:19:02,183
These handsome devils
are the perfect example.
254
00:19:03,559 --> 00:19:05,159
Bumphead parrotfish.
255
00:19:07,613 --> 00:19:09,875
They are the local groundskeepers,
256
00:19:09,899 --> 00:19:13,210
clearing the reef
of dead algae-covered coral.
257
00:19:18,407 --> 00:19:24,080
Recently, as our oceans have warmed,
coral reefs have bleached and died.
258
00:19:25,081 --> 00:19:27,851
Reefs with parrotfish are quickly cleaned,
259
00:19:27,875 --> 00:19:31,504
and new coral can recolonize
so the reef lives on.
260
00:19:33,047 --> 00:19:36,759
Reefs that have lost
to their parrotfish rarely recover.
261
00:19:41,472 --> 00:19:45,376
Parrotfish are important
to maintain the health of the reef...
262
00:19:45,601 --> 00:19:48,545
but Doug also discovers
another important fish.
263
00:19:49,188 --> 00:19:52,525
The incredible, workaholic cleaner wrasse.
264
00:19:55,361 --> 00:19:58,507
DOUG: There are moments in the reef
where it becomes very obvious
265
00:19:58,531 --> 00:20:00,741
how controlled and complex
266
00:20:00,950 --> 00:20:04,006
the relationships
between the individual animals are.
267
00:20:04,030 --> 00:20:08,318
And one of them, for sure,
is watching cleaner wrasse do their work.
268
00:20:09,333 --> 00:20:11,603
They do an enormously important job,
269
00:20:11,627 --> 00:20:14,314
and that's pick the parasites
and dead skin
270
00:20:14,338 --> 00:20:15,982
and scales and everything else off.
271
00:20:16,006 --> 00:20:17,901
You know, they're getting
right inside their mouths
272
00:20:17,925 --> 00:20:21,470
and inside their gills.
They're constantly busy.
273
00:20:22,012 --> 00:20:24,807
They are just so fun to watch.
274
00:20:26,225 --> 00:20:27,994
And they, kind of,
do this funny little dance
275
00:20:28,018 --> 00:20:29,951
to try and bring in business.
276
00:20:32,273 --> 00:20:35,073
Everyone comes to their cleaning stations.
277
00:20:35,267 --> 00:20:36,947
Cute little reef fish.
278
00:20:37,862 --> 00:20:40,129
And then you've got big predators.
279
00:20:40,906 --> 00:20:42,926
I tell you, it really takes
your breath away
280
00:20:42,950 --> 00:20:44,219
when you watch a cleaner wrasse
281
00:20:44,243 --> 00:20:47,110
going into the mouth
of a two-feet predator.
282
00:20:47,413 --> 00:20:49,182
There's just this convention
on the reef,
283
00:20:49,206 --> 00:20:53,937
they do not touch the cleaner wrasse.
It's one of those really lovely examples
284
00:20:53,961 --> 00:20:57,715
of how intricate
the relationships on a reef are.
285
00:21:01,844 --> 00:21:04,865
NARRATOR: While Doug continues
to explore the interconnections
286
00:21:04,889 --> 00:21:07,022
between the fish and the reef...
287
00:21:08,100 --> 00:21:11,270
back in the Red Sea,
Roger is about to find out
288
00:21:11,687 --> 00:21:14,354
that dolphins have similar dependencies.
289
00:21:16,984 --> 00:21:19,884
Angela has discovered
an incredible connection
290
00:21:20,112 --> 00:21:22,642
that dolphins have with the coral here.
291
00:21:22,666 --> 00:21:26,428
ROGER: I was really excited
about this one particular unique behavior
292
00:21:26,452 --> 00:21:27,838
that Angela had told me about,
293
00:21:27,862 --> 00:21:30,934
which I was really determined
to capture on film.
294
00:21:38,631 --> 00:21:41,735
NARRATOR: Angela has brought Roger
to a very special location
295
00:21:41,759 --> 00:21:44,626
that the dolphins
like to visit every day...
296
00:21:46,013 --> 00:21:48,680
and from which they reap great benefits.
297
00:21:49,391 --> 00:21:52,315
ROGER: The key focus for me
was that feeling, as a cameraman,
298
00:21:52,339 --> 00:21:56,541
knowing this is a unique piece of behavior
and is that wonderful pressure...

(DOLPHINS SQUEAL)
302
00:22:05,032 --> 00:22:08,220
NARRATOR: Angela's hard-earned
acceptance by the dolphins
303
00:22:08,244 --> 00:22:12,706
is what allowed her to follow them
and make this incredible discovery.
304
00:22:14,500 --> 00:22:16,645
ANGELA:
There is one certain kind of coral.
305
00:22:16,669 --> 00:22:18,802
It's called the gorgonian coral.
306
00:22:19,129 --> 00:22:25,469
And they really like to rub each body part
in this coral because it's quite soft.
307
00:22:32,685 --> 00:22:34,746
This rubbing behavior seems to be
308
00:22:34,770 --> 00:22:38,107
such an important aspect
in their daily life.
309
00:22:43,445 --> 00:22:47,285
ROGER: So, it's so wonderful
to see them, kind of, lining up.
310
00:22:47,491 --> 00:22:50,136
And they're very gentle.
They don't like fight to get through.
311
00:22:50,160 --> 00:22:54,384
And they're very courteous and allow
the one to go after the other.
312
00:22:54,540 --> 00:22:57,484
And then they circle back
and go through again.
313
00:23:03,716 --> 00:23:06,516
So, it's a wonderful
social ritual as well.
314
00:23:10,723 --> 00:23:13,159
ANGELA: What we also know
about different corals,
315
00:23:13,183 --> 00:23:15,516
they have antibacterial substances.
316
00:23:16,854 --> 00:23:20,649
So, it could also be
that the dolphins actually use also
317
00:23:20,816 --> 00:23:26,906
these corals for medicine, for example,
for even prevention for skin diseases.
318
00:23:29,325 --> 00:23:31,261
It's difficult to really prove it
319
00:23:31,285 --> 00:23:34,622
because it can be also
a very nice feeling,
320
00:23:35,414 --> 00:23:40,669
but we have to find out if it's a really
awareness of self-medication.

(DOLPHINS WHISTLING)
322

NARRATOR:
Angela's groundbreaking observations
323
00:23:44,715 --> 00:23:46,782
have broaden our understanding,
324
00:23:46,884 --> 00:23:50,846
and also pose important new questions
about dolphin behavior.
325
00:23:52,765 --> 00:23:55,726
ROGER: The hypothesis
that Angela's exploring,
326
00:23:56,185 --> 00:23:58,705
and you know,
if this can be proven to be true,
327
00:23:58,729 --> 00:24:01,629
it just highlights the amazing
interdependence
328

between these mammals
and the coral reefs.

but they're also actually coming
to heal themselves.

NARRATOR: Angela hopes to reveal
more about these dolphins' lives

so that we can protect them

this color, this beauty.

but the reef has its back alleys, too.
339
00:24:48,153 --> 00:24:49,833
It's got its dark places.
340
00:24:50,447 --> 00:24:51,865
Places where...
341
00:24:52,032 --> 00:24:57,496
you know, visually, things aren't just
all joy and beauty and vibrancy,
342
00:24:57,830 --> 00:25:00,958
but feel a little bit more
on the sinister side.
343
00:25:03,335 --> 00:25:07,464
NARRATOR: They are the places
that most divers dare not venture.
344
00:25:09,800 --> 00:25:12,067
Doug and his team are in Malaysia,
345
00:25:12,344 --> 00:25:14,024
on their way to Sipadan,
346
00:25:14,054 --> 00:25:18,100
an oceanic island
with a unique and hidden secret
347
00:25:18,517 --> 00:25:21,781
that reveals the dangers
some of our characters face
348
00:25:21,895 --> 00:25:23,575
right in their backyard.
349
00:25:24,481 --> 00:25:27,484
Sipadan is an extraordinary,
little island.
350
00:25:28,277 --> 00:25:31,989
It's a rock in the middle
of hundreds of meters of water.
351
00:25:32,656 --> 00:25:34,450
And it's a marine reserve,
352
00:25:34,616 --> 00:25:38,454
and there is just
an absolute heap of turtles here.
353
00:25:42,958 --> 00:25:46,606
NARRATOR: This reef would seem
like the perfect sanctuary.
354
00:25:47,296 --> 00:25:51,258
But beneath its tranquil shell
hides potential catastrophe
355
00:25:51,592 --> 00:25:53,272
for any wayward turtle.
356
00:25:55,471 --> 00:25:58,891
Inside the reef structure,
there's a catacomb.
357
00:25:59,266 --> 00:26:01,799
And that's what they are here to film.
358
00:26:02,046 --> 00:26:05,374
DOUG: I had heard of Turtle Cave
20 years previously,
359
00:26:05,481 --> 00:26:07,614
and how tricky it was to get in.
360
00:26:08,609 --> 00:26:09,794
By no means... (CHUCKLES)
361
00:26:09,818 --> 00:26:12,589
...a small operation.
Just even getting the kit in there,
362
00:26:12,613 --> 00:26:16,885
before we even start thinking
of lighting it or doing the photography.
363
00:26:16,909 --> 00:26:18,720
We've got a jib,
which is like a big boom
364
00:26:18,744 --> 00:26:21,880
with a camera on one end
and weights on the other.
365
00:26:22,664 --> 00:26:24,601
We've got communications underwater,
366
00:26:24,625 --> 00:26:27,358
which mean that we can
talk to each other.
367
00:26:28,378 --> 00:26:30,231
We do have comms with the boat,
368
00:26:30,255 --> 00:26:33,610
um, but we lose that as soon
as we're through the cave entrance.
369
00:26:33,634 --> 00:26:35,820
DOUG: (OVER RADIO)
Topside, topside, this is divers.
370
00:26:35,844 --> 00:26:37,947
We are just about to enter the cave.
371
00:26:37,971 --> 00:26:39,491
See you on the other side.
372
00:26:39,515 --> 00:26:42,827
HELEN: They could be down there
for a good three hours.
373
00:26:42,851 --> 00:26:44,370
If anything does go wrong,
374
00:26:44,394 --> 00:26:47,373
there's really nothing
that we can do from up here.
375
00:26:47,397 --> 00:26:49,330
All we can really do is wait.
376
00:26:50,851 --> 00:26:54,051
So, fingers crossed,
it all goes according to plan.

DOUG: We realize that this is going to be
a really tough place for us to work.
384
00:27:17,136 --> 00:27:18,696
We have to lay lines
385
00:27:18,720 --> 00:27:22,048
so that we could feel our way
in and out of the cave.
386
00:27:22,266 --> 00:27:25,078
There's no light in there.
It's a small passage.
387
00:27:25,102 --> 00:27:27,769
We only illuminate it with a flashlight.
388
00:27:28,514 --> 00:27:32,034
Okay now, so, you're getting glimpses
of just how remote
389
00:27:32,167 --> 00:27:34,412
and how difficult to get into,
and therefore,
390
00:27:34,436 --> 00:27:37,036
difficult to get out of this space was.
391
00:27:38,448 --> 00:27:40,784
I never felt completely at ease.
392
00:27:41,869 --> 00:27:43,149
(WATER SLOSHING)
393
00:27:49,126 --> 00:27:51,980
DOUG: Usually, you know,
when you're diving open ocean,
394
00:27:52,004 --> 00:27:55,441
you get a problem, you run out of gas,
you got an equipment problem,
395
00:27:55,465 --> 00:27:58,486
you just go up. And in a cave,
you can't do that.
396
00:27:58,510 --> 00:28:01,847
There's no up. (CHUCKLES)
You know, there's only out.
397
00:28:04,308 --> 00:28:06,870
And then, obviously, the other big thing
is it's dark in there, you know,
398
00:28:06,894 --> 00:28:10,123
from an equipment point of view,
so we're going to have to light it.
399
00:28:10,147 --> 00:28:13,835
Most of the thought went into how
we were going to logistically do it
400
00:28:13,859 --> 00:28:16,963
rather than the actual visuals
of what it was going to look like.
401
00:28:16,987 --> 00:28:20,300
Then it really wasn't until I turned
the lights on in the cave
402
00:28:20,324 --> 00:28:23,780
that I really got a sense
of what sort of place it was.
403
00:28:23,952 --> 00:28:26,246
What I saw was a tomb.
404
00:28:27,039 --> 00:28:29,306
And on the ledges of these caverns
405
00:28:29,374 --> 00:28:32,228
lay the almost perfect skeletons
of green turtles
406
00:28:32,252 --> 00:28:34,719
that had, over the years, died there.

NARRATOR: Doug must move
very slowly and carefully.
413
00:29:05,369 --> 00:29:08,169
The cave floor is covered
in fine sediment.
414
00:29:12,751 --> 00:29:15,618
Some believe this to be
the powdered remains
415
00:29:15,837 --> 00:29:21,426
of thousands of turtle skeletons
that have crumbled over countless ages.
416
00:29:21,969 --> 00:29:25,389
And one false move
could cloud the entire cave,
417
00:29:25,639 --> 00:29:29,095
making it difficult for the crew
to find their way out.
418
00:29:34,982 --> 00:29:37,317
After hours of meticulous setup,
419
00:29:38,277 --> 00:29:41,349
Doug starts to reveal
the cave's haunting secrets
420
00:29:41,446 --> 00:29:45,993
from the perspective of a turtle
who has tragically lost its way.
421
00:29:53,792 --> 00:29:56,259
DOUG: It felt like being in a church.
422
00:29:56,586 --> 00:29:59,119
I felt enormous respect for the place.
423
00:29:59,298 --> 00:30:02,031
There was a sense of peace and reverence.
424
00:30:03,218 --> 00:30:06,805
An eerie connection to something.
425
00:30:08,473 --> 00:30:09,683
We all felt it.
426
00:30:10,809 --> 00:30:13,881
A coral reef, in many ways,
is a giver of life...
427
00:30:14,896 --> 00:30:16,336
but it also takes.

It was really quite touching
to see all these turtle skeletons
433
00:30:50,265 --> 00:30:52,660
in the bottom of the cave,
and then, you know,
434

just imagining the turtles
when they got lost in there
435
00:30:55,854 --> 00:30:58,721
and how scared and afraid
they must've been.
436
00:31:02,235 --> 00:31:05,381
NARRATOR: To convey the broader story
of this undersea world,
437
00:31:05,405 --> 00:31:08,797
the filmmakers wanted to balance
these harsh realities
438
00:31:09,201 --> 00:31:11,734
with scenes of beauty and enchantment.
439
00:31:12,621 --> 00:31:14,141
And back in Hawaii,
440
00:31:14,331 --> 00:31:17,918
Didier has found
the greatest enchantment of all.
441
00:31:20,170 --> 00:31:22,547
A singing male humpback whale
442
00:31:23,173 --> 00:31:27,177
with hundreds of others
from miles around joining the chorus.

(HUMPBACK WHALE SINGING)
444
00:31:30,889 --> 00:31:34,217
NARRATOR: Just 50 years ago,
these waters were quiet.
445
00:31:36,228 --> 00:31:40,580
Scientist, Joe Mobley, has been monitoring
their population recovery.
446
00:31:42,526 --> 00:31:45,947
JOE: Humpback whales in North Pacific
were hunted to near extinction
447
00:31:45,971 --> 00:31:48,238
until they were protected in 1966.
448
00:31:48,698 --> 00:31:50,927
At that time, there were probably
under a thousand whales
449
00:31:50,951 --> 00:31:52,551
that came to Hawaii.
450
00:31:52,577 --> 00:31:54,579
But now, 50 years later,
451
00:31:54,996 --> 00:31:59,668
there are maybe as many as 10,000 animals
that visit the Hawaiian Islands.
452
00:32:00,752 --> 00:32:04,784
So, this day on the Luckey Strike,
we were looking for a singer.
453
00:32:04,813 --> 00:32:07,568
To show that the whales
communicate together,
454
00:32:07,592 --> 00:32:09,272
it's part of a community.
455
00:32:09,428 --> 00:32:13,825
NARRATOR: But nothing prepared Didier
for what he was about to encounter.
456
00:32:13,849 --> 00:32:15,743
...hundred feet down
and we can see the back fins.

00:32:15,767 --> 00:32:18,079
There are a lot of mackerel showing here,
which is...

That's a whale right here,

- It's down a hundred feet.
- He's right there.
460
00:32:24,234 --> 00:32:27,213
- He was singing away...
- DIDIER: I heard it, too.
461
00:32:27,237 --> 00:32:28,756
Well, the girls said they could hear him
462
00:32:28,780 --> 00:32:31,008
- clear as could be on the bow.

we can hear the male singing so strong

00:33:29,925 --> 00:33:34,638
DIDIER: Then, a third whale came,
and they start to dance together.

00:34:23,395 --> 00:34:30,360
It's really a gift from nature
to be first row in the theater.
477
00:34:36,616 --> 00:34:38,296
Diving with those giants,
478
00:34:38,868 --> 00:34:41,997
you finally realize how small you are.

00:34:54,175 --> 00:34:57,800
That was one of the best moments
of my life.
480
00:34:58,054 --> 00:34:59,787
That was just magnificent.

You can't forget any of those moments

to capture is just a tiny glimpse

into the humpback's complex,

to a whole new level.

They're not constrained.
494
00:35:59,707 --> 00:36:05,246
And you really see that perhaps,
most beautifully expressed when they surf.

NARRATOR:
Surfing dolphins are a regular sight
496
00:36:09,459 --> 00:36:12,915
on the Wild Coast of South Africa,
where Roger grew up.
497
00:36:14,214 --> 00:36:19,094
Now, he's returning to his roots
with a team of big wave specialists
498
00:36:19,594 --> 00:36:22,555
to try and film
this amazing dolphin behavior.
499
00:36:25,433 --> 00:36:28,871
ROGER: The reason we chose the Wild Coast
is that we know it's got dolphins.
500
00:36:28,895 --> 00:36:31,499
We know that in the winter,
when the winter swells come through,
501
00:36:31,523 --> 00:36:33,723
it's got these incredible swells.

is to film them by getting
503
00:36:37,529 --> 00:36:39,948

00:36:44,577 --> 00:36:49,057
has attached a gyro-stabilized camera
on the back of a high-speed boat,
506
00:36:49,433 --> 00:36:54,254
while skipper, Carl, negotiates the boat
behind the breaking waves.
507
00:36:56,005 --> 00:36:58,805
Pro surf veteran, Paris,
will use a jet ski
508
00:36:58,967 --> 00:37:02,137
to place Roger
right in front of the break.
509
00:37:04,013 --> 00:37:05,373
The stage is set,
510
00:37:05,807 --> 00:37:08,707
and the dolphins have turned up
as if on cue,
511
00:37:08,852 --> 00:37:11,652
traveling up the coastline
in large groups.
512
00:37:12,647 --> 00:37:15,984
But the crew have just met
their first hurdle.
513
00:37:16,568 --> 00:37:22,532
Ironically, the infamous Wild Coast
has turned completely calm.
514
00:37:24,576 --> 00:37:28,280
We've passed literally, I would say,
two to three hundred dolphins,
515
00:37:28,304 --> 00:37:31,517
maybe, you know, in about
six or seven different pods.
516
00:37:31,541 --> 00:37:35,587
So, the dolphins are here,
but absolutely no swell.
517
00:37:36,045 --> 00:37:38,449
It's good that we got dolphins,
we just need a decent wave.
518
00:37:38,473 --> 00:37:41,273
At the moment we got no decent wave, so...
519
00:37:41,634 --> 00:37:44,321
Hopefully in the next two days,
we're supposed to get some better swells.
520
00:37:44,345 --> 00:37:47,825
So, it's just a case of waiting
and hoping that the swell picks up
521
00:37:47,849 --> 00:37:51,060
and that dolphins actually fancy
having a surf.
522
00:37:55,690 --> 00:37:59,736
But what we did get
was this incredibly clean patch of water,
523
00:37:59,944 --> 00:38:02,811
which in the Transkei
is very, very unusual.
524
00:38:03,198 --> 00:38:04,675
So, we took this opportunity
525
00:38:04,699 --> 00:38:08,542
to try and get some underwater shots
of these dolphins coming through.
526
00:38:08,566 --> 00:38:12,123
Holding fingers, fins,
crossing rostrums and blowholes
527
00:38:12,332 --> 00:38:14,101
and flukes and flippers
and hands and feet.
528
00:38:14,125 --> 00:38:16,792
Everything we can cross, we're crossing.
529
00:38:17,629 --> 00:38:19,940
NARRATOR:
Roger dives into the clear shallows
530
00:38:19,964 --> 00:38:21,484
of the beach break.
531
00:38:24,385 --> 00:38:28,097
And soon, an enthusiastic
dolphin pod approaches.
532
00:38:28,348 --> 00:38:29,700
(DOLPHINS SQUEALING)
533
00:38:29,724 --> 00:38:32,661
ROGER: When I got in the water
with the dolphins for the first time,
534
00:38:32,685 --> 00:38:35,831
there's this kind of strange jostling
back flexing behavior.
535
00:38:35,855 --> 00:38:40,085
Now, whether that was some social,
you know, interaction, I'm not sure.
536
00:38:40,109 --> 00:38:43,047
And I've never seen this before
anywhere else in the world.
537
00:38:43,071 --> 00:38:45,240
(DOLPHINS WHISTLING)
538
00:38:46,658 --> 00:38:50,882
NARRATOR: As luck would have it,
with Roger now in amongst the pod,
539
00:38:50,912 --> 00:38:53,045
a set of waves finally comes in.
540
00:38:54,457 --> 00:38:57,043
And our lead actors are in business.
541
00:38:59,295 --> 00:39:02,239
ROGER:
The speed that came through was amazing.
542
00:39:02,549 --> 00:39:06,453
You actually see the way
they are using the energy of the wave
543
00:39:06,511 --> 00:39:09,281
to gain the momentum.
They're riding the pressure wave.
544
00:39:09,305 --> 00:39:11,742
And then you see them turn,
sort of build up speed,
545
00:39:11,766 --> 00:39:13,446
and then they bank left.
546
00:39:13,643 --> 00:39:16,330
And it's that pressure that shoots them
out the back of the wave.
547
00:39:16,354 --> 00:39:19,500
And it was just marvelous
to be in amongst all of that.
548
00:39:19,524 --> 00:39:21,609
It was just such a bonus.
549
00:39:23,777 --> 00:39:25,055
NARRATOR: But soon,
550
00:39:25,079 --> 00:39:27,716
the swell begins
to get dangerous for Roger.
551
00:39:27,740 --> 00:39:29,020
Time to get out.
552
00:39:31,578 --> 00:39:33,371
At last, surf is up.
553
00:39:33,872 --> 00:39:36,249
And with it, more dolphins.
554
00:39:36,666 --> 00:39:38,352
ROGER: (OVER RADIO)
Hello, do you read me?
555
00:39:38,376 --> 00:39:41,647
There's quite a lot of dolphins
that are moving for the surf zone.
556
00:39:41,671 --> 00:39:45,317
So, yeah, looking very strong.
I think we're going to get something.
557
00:39:45,341 --> 00:39:46,426
Come on down.
558
00:39:48,469 --> 00:39:52,140
NARRATOR: Finally,
it's action stations for Jamie's team.
559
00:39:56,603 --> 00:39:58,247
JAMIE: Dolphins in the wave.
560
00:39:58,271 --> 00:40:02,815
NARRATOR: Carl must maneuver his boat
skillfully inside the surf zone...
561
00:40:03,109 --> 00:40:06,009
and get Jamie into the best
possible position.
562
00:40:07,655 --> 00:40:09,800
JAIMIE: You have to outrun the wave.
563
00:40:09,824 --> 00:40:12,136
But then, at certain point,
you have to get out, which means
564
00:40:12,160 --> 00:40:13,929
going over the top
of the 15-foot wave,
565
00:40:13,953 --> 00:40:15,639
so there's a 15-foot drop
in the back of it.
566
00:40:15,663 --> 00:40:19,193
NARRATOR: As they battle the waves,
Carl must also guide Jamie to where
567
00:40:19,217 --> 00:40:21,084
the dolphins might leap out.
568
00:40:21,703 --> 00:40:23,383
Watch out. There they go.
569
00:40:25,006 --> 00:40:28,014
CARL:
Yeah. So, we got in the face of that wave.
570
00:40:29,469 --> 00:40:31,196
JAMIE: Technically, it's very tricky to be
571
00:40:31,220 --> 00:40:33,382
tight on a dolphin
that's swimming through a wave whilst
572
00:40:33,406 --> 00:40:36,206
you're driving the other way
at high speed.
573
00:40:38,728 --> 00:40:41,271
NARRATOR:
But it finally starts to pay off
574
00:40:41,295 --> 00:40:45,109
as Jamie captures wave after wave
of dolphin magic.
575
00:40:54,577 --> 00:40:58,353
JAMIE: It's the most exciting,
dynamic thing that I've done.
576
00:41:06,839 --> 00:41:10,945
NARRATOR: But Carl mustn't get caught
too far in front of the waves.
577
00:41:10,969 --> 00:41:14,361
If they begin to crest,
they can easily flip his boat.
578
00:41:15,640 --> 00:41:18,173
This is where Roger and Paris come in.
579
00:41:18,801 --> 00:41:21,330
- Time to deploy the jet ski.
- Yeah. Let's go.
580
00:41:21,354 --> 00:41:23,374
ROGER: It was the first time
that I've ever attempted
581
00:41:23,398 --> 00:41:25,417
to film dolphins from a jet ski.
582
00:41:25,441 --> 00:41:27,378
But what we hoped for was just to get
583
00:41:27,402 --> 00:41:30,172
one or two unique shots
in front of the wave.
584
00:41:30,196 --> 00:41:33,741
Those waves were big, you know.
It's a big wave.
585
00:41:34,701 --> 00:41:37,054
You've got a really skilled pilot
trying to get you
586
00:41:37,078 --> 00:41:38,847
into these really difficult situations
587
00:41:38,871 --> 00:41:41,943
where that wave could just swamp you
at any time.
588
00:41:42,291 --> 00:41:43,811
Paris was just astounding.
589
00:41:43,835 --> 00:41:47,803
He was able to just anticipate
how the wave was going to break.
590
00:41:48,297 --> 00:41:49,867
I'll never forget that moment where
591
00:41:49,891 --> 00:41:52,444
there was a really nice break
coming through,
592
00:41:52,468 --> 00:41:54,735
really good-sized pod of dolphins.
593
00:41:55,555 --> 00:41:57,755
We really had a go at one wave...
594
00:41:59,308 --> 00:42:03,404
and then I just remember seeing dolphins
in the face of the wave.
595
00:42:04,479 --> 00:42:07,999
Paris has got to wait, wait, wait.
He's got to judge it.
596
00:42:09,091 --> 00:42:12,840
Just this, you know, wonderful image
of them all racing down the wave.
597
00:42:12,864 --> 00:42:16,427
And then, as that wave breaks,
he's going to accelerate us out of there.
598
00:42:16,451 --> 00:42:18,220
And it happened so quickly.
599
00:42:18,244 --> 00:42:20,705
(PARIS AND ROGER CHEERING)
600
00:42:24,667 --> 00:42:28,315
ROGER: It was really the shot
that I was so hoping to get.
601
00:42:31,799 --> 00:42:34,319
This is so exhilarating.
You've been waiting for so long, you know,
602
00:42:34,343 --> 00:42:36,739
you're sitting,
you're waiting for, like, days and days.
603
00:42:36,763 --> 00:42:39,324
And then suddenly, you know,
the set's here and everything's right.
604
00:42:39,348 --> 00:42:41,410
And in the next minute, you know,
Stevie just picks up,
605
00:42:41,434 --> 00:42:43,620
he goes, "Pick up the things,"
and, bang, you know, on it,
606
00:42:43,644 --> 00:42:46,331
exactly as we predicted,
just jumping down the face,
607
00:42:46,355 --> 00:42:48,625
surfing the wave together,
jumping out the back.
608
00:42:48,649 --> 00:42:51,049
ROGER: I mean, it's fantastic, yeah.
609
00:42:52,070 --> 00:42:56,024
NARRATOR: Our filmmakers have captured
some incredible, dynamic scenes
610
00:42:56,048 --> 00:42:57,842
of dolphins letting loose.
611
00:42:59,869 --> 00:43:03,133
But a dolphin's daily life
is not all fun and games.
612
00:43:05,917 --> 00:43:07,784
They also need to find food,
613
00:43:08,294 --> 00:43:10,627
not often found on the reef itself.
614
00:43:15,468 --> 00:43:18,668
And one of the most amazing
dolphin feeding grounds
615
00:43:18,971 --> 00:43:20,411
is in the Bahamas.
616
00:43:21,808 --> 00:43:23,541
Onboard the Dolphin Dream,
617
00:43:23,660 --> 00:43:27,063
our Bahamian team are relying
on skipper Scott Smith,
618
00:43:27,480 --> 00:43:30,983
a veteran dolphin finder,
to take them to the action.
619
00:43:33,820 --> 00:43:36,448
Joining the crew
for this portion of the story
620
00:43:36,472 --> 00:43:38,472
is cinematographer Paul Atkins
621
00:43:38,908 --> 00:43:43,900
a marine biologist and dolphin specialist
who's filmed them all over the world.
622
00:43:54,173 --> 00:43:57,903
PAUL: I've been filming dolphins
and whales for over 30 years.
623
00:43:57,927 --> 00:44:01,281
So, I've filmed bottlenose dolphins
in the Bahamas before.
624
00:44:01,305 --> 00:44:04,172
I always look for an opportunity
to go back.
625
00:44:05,309 --> 00:44:08,209
It's just always a thrill
to get in the water
626
00:44:08,356 --> 00:44:11,156
and to see animals that I'm familiar with.
627
00:44:12,483 --> 00:44:15,254
And sometimes,
I feel like they remember me,
628
00:44:15,278 --> 00:44:18,178
that they're coming up to me
and saying hello.
629
00:44:18,698 --> 00:44:21,218
Eventually, when they stop paying
attention to you,
630
00:44:21,242 --> 00:44:23,554
and then you become a part of their tribe.
631
00:44:23,578 --> 00:44:27,099
And it's an extraordinary experience
when you can just travel with them
632
00:44:27,123 --> 00:44:29,083
and see what they do.
633
00:44:29,750 --> 00:44:31,350
(DOLPHINS WHISTLING)
634
00:44:31,460 --> 00:44:36,068
NARRATOR: Paul is here to capture
dolphins hunting in a very special way.
635
00:44:38,676 --> 00:44:41,721
They use a type of sonar
called echolocation,
636
00:44:42,638 --> 00:44:45,171
which works kind of like x-ray vision.
637
00:44:47,560 --> 00:44:49,729
(CLICKING)
638
00:44:50,688 --> 00:44:55,168
They emit a series of rapid-fire clicks
that bounce off hidden objects,
639
00:44:56,110 --> 00:44:59,118
allowing them to locate food
beneath the sand...
640
00:45:02,366 --> 00:45:04,493
food like razorfish.
641
00:45:09,790 --> 00:45:12,590
PAUL:
When you're with a group of dolphins,
642
00:45:12,752 --> 00:45:16,172
you feel privileged
to be witnessing their culture.
643
00:45:18,674 --> 00:45:23,512
Dolphins are one of the few animals
besides humans and great apes
644
00:45:23,804 --> 00:45:26,505
that actually have been shown
to have culture.
645
00:45:26,529 --> 00:45:29,665
And that culture is based
on ways of finding food.
646
00:45:31,145 --> 00:45:32,521
(CLICKING)
647
00:45:40,488 --> 00:45:41,924
NARRATOR: Around the world,
648
00:45:41,948 --> 00:45:45,135
dolphins have developed
different feeding strategies
649
00:45:45,159 --> 00:45:46,959
depending on their habitat.
650
00:45:48,204 --> 00:45:52,166
And some of them involve
extraordinary levels of teamwork.
651
00:45:56,587 --> 00:45:59,215
These shallow tidal mudflats in Florida
652
00:45:59,475 --> 00:46:03,379
are a rich feeding ground
for many marine and coastal animals.
653
00:46:05,012 --> 00:46:07,282
And with its great abundance of fish,
654
00:46:07,306 --> 00:46:12,103
it has given rise to a unique
and spectacular dolphin hunting technique
655
00:46:12,812 --> 00:46:14,647
known as mud ringing.
656
00:46:20,528 --> 00:46:22,208
Scientist, Laura Engleby,
657
00:46:22,655 --> 00:46:26,815
has brought cinematographer
Jamie McPherson onto these tidal flats
658
00:46:27,034 --> 00:46:29,701
in search of this remarkable phenomenon.
659
00:46:32,873 --> 00:46:35,435
For Jamie, it may not be as heart-stopping
660
00:46:35,459 --> 00:46:38,259
as filming dolphins surfing the big waves,
661
00:46:38,504 --> 00:46:40,371
but it is just as difficult.
662
00:46:44,719 --> 00:46:47,186
- JAMIE: Oh, damn it.
- (LAURA LAUGHS)
663
00:46:47,340 --> 00:46:50,325
JAMIE: From the boat, it's tricky because
you have to work out where they are.
664
00:46:50,349 --> 00:46:52,461
The camera's right on sea level.
665
00:46:52,485 --> 00:46:54,246
You only see them when they surface.
666
00:46:54,270 --> 00:46:55,706
So, you see the fins occasionally.
667
00:46:55,730 --> 00:46:57,849
You're trying to work out
where they're going to go.
668
00:46:57,873 --> 00:46:59,835
It's very hard to coordinate that.
669
00:46:59,859 --> 00:47:03,635
It's very tricky to be in the right place
at the right time.
670
00:47:05,364 --> 00:47:08,593
NARRATOR: Suddenly, the dolphins
look like they are teaming up
671
00:47:08,617 --> 00:47:10,434
and coordinating their efforts.
672
00:47:10,458 --> 00:47:11,930
WOMAN:
No, Jamie, now they're to the right.
673
00:47:11,954 --> 00:47:13,682
- To the right.
- JAMIE: Coming where?
674
00:47:13,706 --> 00:47:15,259
- WOMAN 1: To your right.
- WOMAN 2: Right.
675
00:47:15,283 --> 00:47:17,108
WOMAN 1: See them?
676
00:47:18,461 --> 00:47:20,728
NARRATOR: They've started to hunt.
677
00:47:24,066 --> 00:47:27,138
Jamie zeroes in on the action
with his zoom lens.
678
00:47:32,767 --> 00:47:35,434
JAMIE: Well, you see a lot of splashing.
679
00:47:36,604 --> 00:47:40,375
They don't put their heads up to catch
the fish until the very last second.
680
00:47:40,399 --> 00:47:43,545
The dolphins still have to try and catch
fish that's flying through the air.
681
00:47:43,569 --> 00:47:45,797
So, to see the look on their faces
and see how quick they are
682
00:47:45,821 --> 00:47:49,981
at reacting to the fish that are flying
really immerses you in it.
683
00:47:50,034 --> 00:47:52,804
But to understand the behavior
and really see what was going on,
684
00:47:52,828 --> 00:47:54,508
we had to get in the air.
685
00:48:05,975 --> 00:48:09,454
NARRATOR: Spotting dolphin pods
across these vast mudflats
686
00:48:09,478 --> 00:48:11,856
is much easier in a helicopter.
687
00:48:13,140 --> 00:48:14,826
I see some dolphins right down here.
688
00:48:14,850 --> 00:48:18,288
NARRATOR: Each day,
dolphins travel up these tidal channels
689
00:48:18,312 --> 00:48:20,445
into dangerously shallow waters,
690
00:48:21,232 --> 00:48:24,402
lured here by the sheer bounty
of fish to be had.
691
00:48:26,045 --> 00:48:29,309
It looks like they're in
really shallow water there.
692
00:48:30,032 --> 00:48:32,302
NARRATOR:
It's so shallow here at low tide,
693
00:48:32,326 --> 00:48:34,926
they often have to swim on their sides.
694
00:48:39,792 --> 00:48:44,016
This one certainly seems
to be having fun hunting in the sea grass.
695
00:48:44,088 --> 00:48:47,416
LAURA: (OVER RADIO) Aww! (LAUGHS)
What are you doing?
696
00:48:51,387 --> 00:48:53,281
NARRATOR:
But this is not the hunting behavior
697
00:48:53,305 --> 00:48:54,985
the crew are looking for.
698
00:48:55,433 --> 00:48:57,277
So, they continue their search.
699
00:48:57,301 --> 00:48:59,287
- PILOT: Yeah, I'm bringing it around.
- LAURA: All right.
700
00:48:59,311 --> 00:49:00,747
- PILOT: Yeah, preparing...
- LAURA: Yeah...
701
00:49:00,771 --> 00:49:02,165
PILOT:...turning the nose right now...
702
00:49:02,189 --> 00:49:03,583
JAMIE: Yeah, I will. So, we'll just
703
00:49:03,607 --> 00:49:06,128
come back to these guys
if we can't find anything else.
704
00:49:06,152 --> 00:49:07,295
NARRATOR: Nearby,
705
00:49:07,319 --> 00:49:10,132
another group of dolphins
reveal some of the risks
706
00:49:10,156 --> 00:49:12,423
of hunting in such shallow waters.
707
00:49:13,284 --> 00:49:17,514
- LAURA: Oh, they're definitely stranded.
- JAMIE: Yeah, they're definitely stranded.
708
00:49:17,538 --> 00:49:20,851
LAURA: Quite amazing. They made
a little mud hole for themselves.
709
00:49:20,875 --> 00:49:25,035
They have come around in tight circles
and have created a mud hole
710
00:49:25,212 --> 00:49:26,982
to where they can at least swim
711
00:49:27,006 --> 00:49:29,860
and not get sun burns
and not flip on their sides
712
00:49:29,884 --> 00:49:32,070
because the worse thing,
when they're stuck like that,
713
00:49:32,094 --> 00:49:36,533
is they can crush their internal organs
with their own body weight and overheat.
714
00:49:36,557 --> 00:49:38,994
JAMIE: It's horrible to see
'cause you can see they're stressed out,
715
00:49:39,018 --> 00:49:41,220
you can see they're worried,
and there's nothing you can do.
716
00:49:41,244 --> 00:49:45,148
You're in a helicopter flying around
and no one can help them.
717
00:49:46,567 --> 00:49:48,670
NARRATOR:
Laura knows the tide is rising,
718
00:49:48,694 --> 00:49:51,027
so the dolphins will soon be freed.
719
00:49:52,781 --> 00:49:55,284
And before long, they spot something.
720
00:49:56,035 --> 00:49:57,161
Mud clouds.
721
00:50:00,080 --> 00:50:04,304
As they approach, they can see
the dolphins are definitely hunting.
722
00:50:04,585 --> 00:50:07,481
LAURA: From the air,
it offers a whole different perspective
723
00:50:07,505 --> 00:50:09,025
of what's going on.
724
00:50:09,173 --> 00:50:12,903
They're clearly chasing some prey,
but this is a feeding strategy
725
00:50:12,927 --> 00:50:14,821
that hasn't been documented
in the literature
726
00:50:14,845 --> 00:50:17,115
that we're just now,
through this aerial footage,
727
00:50:17,139 --> 00:50:19,672
able to really see what they're doing.
728
00:50:20,851 --> 00:50:23,163
NARRATOR:
But this still isn't the hunting behavior
729
00:50:23,187 --> 00:50:24,920
they've come here to film.
730
00:50:27,566 --> 00:50:29,109
Then, finally,
731
00:50:29,692 --> 00:50:32,422
Jamie spots what they've been looking for.
732
00:50:32,446 --> 00:50:37,409
This dolphin beats up the mud
with its fluke, creating a perfect circle.
733
00:50:39,161 --> 00:50:40,329
A mud ring.
734
00:50:41,121 --> 00:50:43,266
LAURA: (OVER RADIO) Aww. Wow. Aww.
735
00:50:43,290 --> 00:50:45,519
NARRATOR: This technique in itself...
736
00:50:45,543 --> 00:50:48,487
showcases
the dolphin's remarkable intelligence
737
00:50:48,754 --> 00:50:53,175
as they use the muddy substrate
to form the perfect fishing net.
738
00:50:56,386 --> 00:50:59,032
JAMIE: (OVER RADIO) I see they've got
a shoal of fish surrounded.
739
00:50:59,056 --> 00:51:01,034
MAN: (OVER RADIO) Yeah, it's really nice.
740
00:51:01,058 --> 00:51:05,288
NARRATOR: Other dolphins have
corralled the shoal of fish into the ring.
741
00:51:05,312 --> 00:51:08,124
And the entrapped fish,
in trying to escape,
742
00:51:08,148 --> 00:51:10,815
leap straight into their waiting mouths.
743
00:51:24,248 --> 00:51:27,394
JAMIE: (OVER RADIO) Absolutely perfect,
there's a whole shoal of fish.
744
00:51:27,418 --> 00:51:30,618
You can see the dolphins
trying to get around them.
745
00:51:32,464 --> 00:51:34,901
- Look at that, there.
- (LAURA LAUGHS)
746
00:51:34,925 --> 00:51:38,509
- LAURA: That is amazing.
- JAMIE: That's pretty amazing.
747
00:51:42,474 --> 00:51:45,495
JAMIE: I've never seen anything
that coordinated.
748
00:51:45,519 --> 00:51:47,998
And they're definitely working together
and communicating
749
00:51:48,022 --> 00:51:49,916
to better coordinate the ring
750
00:51:49,940 --> 00:51:52,085
and make the fish leap
and land where dolphins are waiting.
751
00:51:52,109 --> 00:51:55,501
- It's, yeah, an amazing display.
- (DOLPHINS CHATTER)
752
00:52:11,462 --> 00:52:13,339
(DOLPHINS CHATTERING)
753
00:52:20,638 --> 00:52:23,438
NARRATOR:
The team's patience has paid off.
754
00:52:23,624 --> 00:52:25,757
They've finally captured on film
755
00:52:26,060 --> 00:52:30,348
this remarkable cooperative
hunting strategy of bottlenose dolphins.
756
00:52:35,235 --> 00:52:38,135
In much deeper waters
off the coast of Hawaii,
757
00:52:38,947 --> 00:52:41,092
our whale team have returned to film
758
00:52:41,116 --> 00:52:43,516
a great gathering of male humpbacks.
759
00:52:46,080 --> 00:52:47,223
But this gathering
760
00:52:47,247 --> 00:52:50,639
is not in the same cooperative spirit
as the dolphins.
761
00:52:51,502 --> 00:52:53,022
Quite the opposite.
762
00:52:54,046 --> 00:52:56,465
An intense competition is brewing.
763
00:52:58,384 --> 00:53:00,987
Here, they gather in the greatest numbers
764
00:53:01,011 --> 00:53:04,807
to take part
in the most spectacular battle in nature.
765
00:53:14,098 --> 00:53:16,710
Back on the Luckey Strike,
Tad has now teamed up
766
00:53:16,734 --> 00:53:19,534
with Paul Atkins
to film this great ritual.
767
00:53:20,197 --> 00:53:25,125
They are following a female humpback
who has a number of males in hot pursuit.
768
00:53:26,495 --> 00:53:29,766
PAUL: There's definitely an air
of excitement and tension when you're
769
00:53:29,790 --> 00:53:32,185
headed out to film one of these battles.
770
00:53:32,209 --> 00:53:35,105
You're never quite sure
what's going to happen.
771
00:53:35,129 --> 00:53:37,996
They're going really fast
at eleven o'clock.
772
00:53:42,803 --> 00:53:47,347
NARRATOR: Professor Joe Mobley
is documenting the activity from the bow.
773
00:53:49,226 --> 00:53:53,770
And as the boat catches up with the pod,
things really start to heat up.
774
00:53:56,024 --> 00:53:58,402
The battle is about to commence.
775
00:54:05,117 --> 00:54:07,584
The males begin to chase one another.
776
00:54:17,963 --> 00:54:19,963
It's a pretty fast-moving pod.
777
00:54:26,263 --> 00:54:29,808
As Paul begin to film
some spectacular surface behavior,
778
00:54:30,392 --> 00:54:33,192
more and more whales join the competition.
779
00:54:36,398 --> 00:54:39,265
All these challengers
are racing to catch up
780
00:54:39,318 --> 00:54:41,851
and displace the current front-runner,
781
00:54:42,279 --> 00:54:45,741
wanting to become the ultimate champion.
782
00:54:55,292 --> 00:54:58,420
Out in front,
the female is setting the pace.
783
00:55:02,800 --> 00:55:06,256
But this surface view does not reveal
the whole combat,
784
00:55:06,470 --> 00:55:08,937
as Joe has speculated for many years.
785
00:55:09,890 --> 00:55:13,661
JOE: The frustrating thing is I'm bound
to the above-surface world,
786
00:55:13,685 --> 00:55:15,789
where we're limited to probably
less than ten percent
787
00:55:15,813 --> 00:55:17,165
of their total behavior.
788
00:55:17,189 --> 00:55:20,645
You know, most of what's important
is going down below.
789
00:55:22,694 --> 00:55:24,289
Looks good for pole cam, right?
790
00:55:24,313 --> 00:55:25,314
Go ahead.
791
00:55:25,614 --> 00:55:27,547
We're going to give it a try.
792
00:55:28,450 --> 00:55:30,970
JOE: So, increasingly, I've been
relying on opportunities like this
793
00:55:30,994 --> 00:55:34,349
to work with film crews
with their high-tech equipment.
794
00:55:34,373 --> 00:55:36,351
And those kinds of instruments
basically give us
795
00:55:36,375 --> 00:55:38,853
a whale's eye view.
It puts us in their world.
796
00:55:38,877 --> 00:55:41,189
Much more likely to answer
the kinds of questions
797
00:55:41,213 --> 00:55:43,813
that we've been asking for decades now.
798
00:55:44,816 --> 00:55:46,110
TAD: Okay, you've got it?
799
00:55:46,134 --> 00:55:49,197
PAUL: So, we designed the granddaddy
of all pole cams,
800
00:55:49,221 --> 00:55:51,407
and this had never been tried before.
801
00:55:51,431 --> 00:55:52,659
MAN: Okay, I got it.
802
00:55:52,683 --> 00:55:56,538
PAUL: And the pole cam system
has to be beefy and sturdy enough
803
00:55:56,562 --> 00:56:00,148
to withstand moving through water
at four to five knots,
804
00:56:00,440 --> 00:56:02,040
sometimes six knots.
805
00:56:04,319 --> 00:56:07,465
NARRATOR: Paul hopes to capture
a unique underwater perspective
806
00:56:07,489 --> 00:56:09,199
of this great contest.
807
00:56:11,451 --> 00:56:14,351
On top deck,
he prepares the viewing monitor.
808
00:56:15,789 --> 00:56:19,245
As the boat races to catch up
with the charging giants,
809
00:56:19,459 --> 00:56:22,659
skipper Tad must get his boat
right alongside them.
810
00:56:31,346 --> 00:56:33,366
PAUL: Okay, there's two whales.
811
00:56:33,390 --> 00:56:35,923
Now there's three whales in the frame.
812
00:56:36,068 --> 00:56:38,868
Okay, there's one
dead center in the frame.
813
00:56:39,104 --> 00:56:40,971
This is great position, Tad.
814
00:56:41,732 --> 00:56:45,252
Oh, he's coming up right here,
right here, this is good.
815
00:56:46,986 --> 00:56:49,386
Stay in and let these guys catch up.
816
00:56:50,198 --> 00:56:53,974
NARRATOR: By combining
Paul's underwater and surface filming
817
00:56:54,411 --> 00:56:56,811
with aerial footage by helicopter...
818
00:56:57,789 --> 00:57:00,456
PAUL: Oh, this is great, Tad. Hold this.
819
00:57:00,830 --> 00:57:05,246
...he starts to reveal the intensity
of this battle like never before.
820
00:57:08,050 --> 00:57:11,487
Okay, there's one below that's coming.
This is great position, Tad.
821
00:57:11,511 --> 00:57:15,415
PAUL: And he's coming up right here,
right here, this is good.
822
00:57:18,435 --> 00:57:19,436
Wow.
823
00:57:19,853 --> 00:57:20,854
Geez.
824
00:57:26,068 --> 00:57:29,140
NARRATOR:
All the whales dive down into the deep.
825
00:57:33,241 --> 00:57:34,921
PAUL: Diving, diving.
826
00:57:36,036 --> 00:57:37,476
And there they go.
827
00:57:38,080 --> 00:57:40,433
Now, we can see them all
diving towards the bottom,
828
00:57:40,457 --> 00:57:42,190
going down about 200 feet.
829
00:57:43,502 --> 00:57:45,313
Sometimes it goes... so we can follow them
830
00:57:45,337 --> 00:57:47,148
straight down the bottom
and you see them.
831
00:57:47,172 --> 00:57:49,734
Looks like they're rubbing on the bottom
at 200 feet.
832
00:57:49,758 --> 00:57:51,402
If we could get a camera down there,
833
00:57:51,426 --> 00:57:53,905
we might find out
where's it's all really happening.
834
00:57:53,929 --> 00:57:57,065
Maybe that's where the actual mating
is occurring.
835
00:57:57,849 --> 00:57:59,202
- Who knows?
- Coming up.
836
00:57:59,226 --> 00:58:00,954
They're still stuck on us right here.
837
00:58:00,978 --> 00:58:03,706
NARRATOR:
Suddenly, erupting back up from the deep,
838
00:58:03,730 --> 00:58:06,775
the conflict resumes
at an even greater pace.
839
00:58:08,110 --> 00:58:10,421
Yeah, yeah, yeah, because this is...
840
00:58:10,445 --> 00:58:12,712
Yeah, this is really getting good.
841
00:58:13,991 --> 00:58:17,319
NARRATOR: Over 25 male whales
charge past the camera,
842
00:58:17,661 --> 00:58:20,261
blowing streams off aggressive bubbles.
843
00:58:20,539 --> 00:58:22,475
- PAUL: Lot of bubbles.
- MAN: Yeah.
844
00:58:22,499 --> 00:58:25,232
- PAUL: Tons of bubbles.
- MAN: Coming up.
845
00:58:32,884 --> 00:58:36,980
NARRATOR: Those in the rear
try to force the front-runners under,
846
00:58:37,014 --> 00:58:42,198
ruthlessly ramming them to slow them down
and take the lead nearest to the female.
847
00:58:46,023 --> 00:58:50,444
This is the most immense
ocean competition in nature.
848
00:58:55,198 --> 00:58:57,451
Finally, as the other males tire,
849
00:58:57,720 --> 00:59:00,984
the two fastest and strongest
take primary positions
850
00:59:02,330 --> 00:59:04,397
hot on the heels of the female.
851
00:59:16,970 --> 00:59:19,978
In the last moments,
a challenger lunges forward
852
00:59:20,157 --> 00:59:22,090
and forces his rival under...
853
00:59:24,644 --> 00:59:26,324
and out of the race...
854
00:59:27,856 --> 00:59:30,525
claiming his place as the victor.
855
00:59:37,824 --> 00:59:39,184
And they're gone.
856
00:59:40,911 --> 00:59:42,591
PAUL: And there they go.
857
00:59:46,625 --> 00:59:49,377
NARRATOR: This battle is finally over.
858
00:59:51,922 --> 00:59:55,300
One mighty humpback has fought
and won the right
859
00:59:55,592 --> 00:59:58,303
to be the protector of our lone female.
860
01:00:04,976 --> 01:00:08,021
Filming this magnificent event
was only possible
861
01:00:08,230 --> 01:00:11,878
because protection has allowed
whale societies to rebuild.
862
01:00:15,320 --> 01:00:19,074
Unfortunately,
such success stories are rare.
863
01:00:20,033 --> 01:00:21,713
And unlike the humpbacks,
864
01:00:22,077 --> 01:00:25,149
the populations
of our ocean's greatest predators
865
01:00:25,205 --> 01:00:26,805
are in huge decline.
866
01:00:32,003 --> 01:00:35,674
Over a hundred million sharks
are fished each year
867
01:00:36,424 --> 01:00:39,752
to satisfy the demands
of the shark finning industry.
868
01:00:41,471 --> 01:00:45,475
Giants like the tiger shark
are becoming increasingly rare.
869
01:00:47,477 --> 01:00:51,637
And their overblown reputation
as frightening and deadly predators
870
01:00:51,773 --> 01:00:53,373
has not helped them.
871
01:01:01,449 --> 01:01:04,512
Paul, however, having filmed sharks
for many years,
872
01:01:04,536 --> 01:01:07,992
knows they are nothing like
this cartoonish stereotype.
873
01:01:10,041 --> 01:01:12,979
The first time I saw sharks underwater,
what impressed me was
874
01:01:13,003 --> 01:01:16,816
how extraordinarily beautiful they are,
how graceful they are,
875
01:01:16,840 --> 01:01:21,064
how perfectly adapted that
they're swimming and how agile they are.
876
01:01:21,678 --> 01:01:24,365
And then, the next thing
that impresses you about sharks,
877
01:01:24,389 --> 01:01:26,617
because you grow up with all of this fear,
878
01:01:26,641 --> 01:01:29,203
is they don't seem
to be threatening you.
879
01:01:29,227 --> 01:01:31,827
PAUL: They don't seem to be that scary.
880
01:01:36,610 --> 01:01:38,477
When tiger sharks show up...
881
01:01:39,321 --> 01:01:41,599
their presence
kind of dominates the scene.
882
01:01:41,623 --> 01:01:44,886
Pretty much, you have your attention
on the tiger shark,
883
01:01:44,910 --> 01:01:46,179
and you never turn your back on it,
884
01:01:46,203 --> 01:01:49,979
because they tend to know
which direction you're looking at,
885
01:01:50,081 --> 01:01:52,948
and they tend to want to come up
behind you.
886
01:01:57,380 --> 01:02:00,318
But they like to test,
they like to see what you are.
887
01:02:00,342 --> 01:02:04,387
And part of that testing
can be pushing its nose into you.
888
01:02:08,225 --> 01:02:10,995
And what you can do
is just put your hand on its nose
889
01:02:11,019 --> 01:02:13,086
and just gently push them away.
890
01:02:13,188 --> 01:02:16,417
PAUL: What other predator on land
could you do that with?
891
01:02:16,441 --> 01:02:20,254
If you did it with bears
that were feeding, or lions, or tigers,
892
01:02:20,278 --> 01:02:22,011
you'd probably get mauled.
893
01:02:22,364 --> 01:02:26,093
And yet, here with one of the biggest,
baddest, predators on the planet,
894
01:02:26,117 --> 01:02:28,429
in terms of the way we feel about them,
895
01:02:28,453 --> 01:02:31,186
and it's perfectly safe to do that, so...
896
01:02:42,884 --> 01:02:46,276
NARRATOR: Sharks are not only
misunderstood by humans,
897
01:02:46,429 --> 01:02:50,909
but their important role in maintaining
a well-balanced ocean ecosystem
898
01:02:51,268 --> 01:02:52,868
is often overlooked.
899
01:02:58,650 --> 01:03:01,653
A healthy coral reef has many sharks,
900
01:03:02,028 --> 01:03:06,324
but in today's oceans, these reefs
are increasingly hard to find.
901
01:03:09,995 --> 01:03:12,723
Underwater cinematographer,
Denis Lagrange,
902
01:03:12,747 --> 01:03:16,651
has known for years
about one of the last strongholds on Earth
903
01:03:17,048 --> 01:03:19,852
for large gatherings of grey reef sharks.
904
01:03:20,547 --> 01:03:25,091
He's in French Polynesia, preparing
to dive these shark-infested waters.
905
01:03:33,268 --> 01:03:37,689
On an incoming tide, hundreds
of reef sharks school in this channel.
906
01:03:47,449 --> 01:03:51,119
Like Paul, Denis has no fear
of these apex predators,
907
01:03:51,536 --> 01:03:54,039
for he knows he is not on their menu.
908
01:03:55,749 --> 01:03:59,061
DENIS: For me, sharks are
one of the most of incredible creature
909
01:03:59,085 --> 01:04:01,552
in the ocean, and you really feel it.
910
01:04:05,884 --> 01:04:08,956
And when we have
all these sharks gather together
911
01:04:09,220 --> 01:04:11,353
and they're really concentrated,
912
01:04:11,431 --> 01:04:13,183
it's an amazing spectacle,
913
01:04:13,350 --> 01:04:17,175
and French Polynesia is the last place,
I think, in the world,
914
01:04:17,199 --> 01:04:18,879
where you can see that.
915
01:04:21,524 --> 01:04:25,300
We try to justify why sharks
should be saved and not killed,
916
01:04:25,487 --> 01:04:30,223
try to fight against shark finning,
but I think it's important to repeat it
917
01:04:30,283 --> 01:04:32,928
because they are
at the top of the food chain.
918
01:04:32,952 --> 01:04:36,088
They're cleaning the reef
of all natural sickness.
919
01:04:55,517 --> 01:04:59,938
So, if you have no predators,
the reef will just not be in good shape.
920
01:05:00,230 --> 01:05:01,430
It's a reality.
921
01:05:02,440 --> 01:05:04,919
We have to try our best
to protect the shark.
922
01:05:04,943 --> 01:05:08,214
And French Polynesia,
it's one of the only country in the world
923
01:05:08,238 --> 01:05:11,133
who really protect the shark.
It's written in the law.
924
01:05:11,157 --> 01:05:15,509
You're not allowed to kill sharks,
you're not allowed to fish sharks.
925
01:05:15,787 --> 01:05:18,265
NARRATOR: And the protection of sharks
in these waters
926
01:05:18,289 --> 01:05:21,425
allows them to fulfil their role
as vital hunters.
927
01:05:23,461 --> 01:05:26,399
But most sharks don't hunt
during daylight hours.
928
01:05:26,423 --> 01:05:29,551
The serious hunting action occurs
after dark.
929
01:05:31,344 --> 01:05:34,864
So, Denis's next dive
would be a much greater challenge,
930
01:05:35,265 --> 01:05:39,310
filming sharks hunting at night
for his very first time.
931
01:05:42,897 --> 01:05:45,630
They put on special chainmail shark suits
932
01:05:45,775 --> 01:05:49,743
designed to stop a reef shark's teeth
from puncturing the skin.
933
01:05:51,281 --> 01:05:54,181
Sharks don't often
intentionally bite humans.
934
01:05:54,742 --> 01:05:58,848
But in the heat of a feeding frenzy,
it's wise to take precautions.
935
01:05:58,872 --> 01:05:59,992
(MAN LAUGHING)
936
01:06:00,123 --> 01:06:03,460
We expect a lot of shark action tonight.
937
01:06:05,336 --> 01:06:07,016
I hope we will survive.

- We should go.

- Are we good?
941
01:06:14,596 --> 01:06:15,680
Yeah.
942
01:06:18,766 --> 01:06:22,030
NARRATOR:
It's more like a special forces operation.
943
01:06:22,520 --> 01:06:24,040
And it needs to be.
944
01:06:26,566 --> 01:06:33,448
(MEN SPEAKING FRENCH)
945
01:06:42,665 --> 01:06:45,532
NARRATOR:
A few sharks appear straight away.
946
01:06:47,921 --> 01:06:49,988
Then the numbers build quickly.
947
01:06:57,263 --> 01:06:59,533
DENIS:
When you first dive down to the reef
948
01:06:59,557 --> 01:07:02,885
and you see this amazing
number of sharks altogether,
949
01:07:03,603 --> 01:07:05,283
you feel a little scared.
950
01:07:12,737 --> 01:07:14,965
NARRATOR: The surface team is anxious.
951
01:07:14,989 --> 01:07:17,856
They can see the sharks
amassing from above.
952
01:07:19,244 --> 01:07:23,596
DENIS: We've never seen that before.
Daytime, the shark kind of lazy,
953
01:07:23,706 --> 01:07:26,477
but as soon as you're diving
at night with them,
954
01:07:26,501 --> 01:07:29,168
you really see how powerful they can be.
955
01:07:35,301 --> 01:07:38,693
NARRATOR: While the fish
remain hidden, they are safe.
956
01:07:44,352 --> 01:07:46,952
But a nervous reef fish breaks cover...
957
01:07:47,522 --> 01:07:49,455
and the feeding frenzy is on.
958
01:07:50,358 --> 01:07:53,546
DENIS: To be eaten by a shark
is a really big issue.
959
01:07:53,570 --> 01:07:57,424
When you have hundreds of them
in front of you or coming right at you,
960
01:07:57,448 --> 01:08:00,553
they don't care about you,
they just want the fish.

No, but then you have to pay attention
967

- to the little fish going between us.
- Oh là là,

DENIS: If they come to you,
I mean, they kick you down.
971
01:08:52,211 --> 01:08:56,108
I really felt it, you know,
a little fish went out of the coral,
972
01:08:56,132 --> 01:08:58,819
and they went on it,
and they don't care about you,

NARRATOR:
On our cinematographers' quest
989
01:09:58,236 --> 01:10:01,781
to share with you
a tiny glimpse into a dolphin's world,
990

of thriving ocean communities.

01:11:09,640 --> 01:11:12,307
Countless creatures will cease to exist.
1004
01:11:14,187 --> 01:11:17,356
And our dolphins will have lost
their vital home.
1005
01:11:21,986 --> 01:11:27,116
But there is hope,
with one of the simplest of solutions...
1006
01:11:28,743 --> 01:11:29,827
protection.
1007
01:11:32,789 --> 01:11:37,960
The best example,
the islands of Palau in Micronesia.
1008
01:11:39,879 --> 01:11:43,174
Didier has come here
to film a very special event.
1009
01:11:44,383 --> 01:11:48,614
DIDIER: So, when I knew I was going
to go to Palau, I was very excited
1010
01:11:48,638 --> 01:11:50,371
because I have never been.
1011
01:11:51,349 --> 01:11:55,829
When I first put my head in the water,
I realized how beautiful it was.
1012
01:11:57,438 --> 01:12:00,542
It's that sort of place
where you have strong upwellings
1013
01:12:00,566 --> 01:12:02,966
bringing rich water from the depths,
1014
01:12:03,903 --> 01:12:05,422
very rich in nutrients.
1015
01:12:05,446 --> 01:12:08,658
Makes a top-class reef, very rich in life,
1016
01:12:09,099 --> 01:12:11,166
with all those fish everywhere.
1017
01:12:11,828 --> 01:12:13,695
And not only the small ones.
1018
01:12:13,955 --> 01:12:15,888
Giants and other predators...
1019
01:12:18,251 --> 01:12:21,151
all kind of fish.
We have all the food chain.
1020
01:12:22,672 --> 01:12:26,551
Mantas, hundreds of sharks,
everyone is here.
1021
01:12:33,683 --> 01:12:35,123
NARRATOR: In 1998,
1022
01:12:35,351 --> 01:12:39,191
everyone thought that this reef
might have been lost forever.
1023
01:12:40,481 --> 01:12:43,693
An El Niٌo event had bleached
and killed the coral.
1024
01:12:45,736 --> 01:12:48,781
But you-know-who stepped in to clean up...
1025
01:12:50,324 --> 01:12:52,410
our trusty bumphead parrotfish.
1026
01:12:54,245 --> 01:12:58,021
And with the added help
of government-enforced protection...
1027
01:12:58,291 --> 01:13:00,501
the reef is now as good as new.
1028
01:13:09,610 --> 01:13:14,699
Not surprisingly, Palau is now famous
for its great fish gatherings.
1029
01:13:15,850 --> 01:13:20,438
Every full moon, all the bumpheads
gather at dawn to spawn.
1030
01:13:22,189 --> 01:13:26,444
This is the legendary spectacle
Didier has come here to film.
1031
01:13:35,536 --> 01:13:38,891
DIDIER: To film the bumpheads spawning
is a special event
1032
01:13:38,915 --> 01:13:42,051
because this is something I do
for the first time.
1033
01:13:43,461 --> 01:13:45,594
First, you see all those fish...
1034
01:13:47,016 --> 01:13:49,883
and it's not ten, 30,
it's hundreds of them.
1035
01:13:51,552 --> 01:13:54,722
They are big massive fish,
like 20, 30 kilos.
1036
01:13:56,974 --> 01:13:59,707
For a cameraman,
this is something unique.
1037
01:14:06,359 --> 01:14:10,088
NARRATOR: Didier must remain poised
and ready the whole time,
1038
01:14:10,112 --> 01:14:13,888
because the actual spawning event
could occur at any moment.
1039
01:14:15,117 --> 01:14:17,679
DIDIER: When they aggregate,
you are on the reef,
1040
01:14:17,703 --> 01:14:20,503
so you wait, you wait,
and all of a sudden,
1041
01:14:20,623 --> 01:14:22,756
they stop to go out in the blue,
1042
01:14:23,084 --> 01:14:25,751
and this is where the action will start.
1043
01:14:26,170 --> 01:14:27,450
This is where...
1044
01:14:27,713 --> 01:14:31,443
things get complicated because you have
to swim against the current,
1045
01:14:31,467 --> 01:14:34,303
and we can't compete with the fish.
1046
01:14:34,470 --> 01:14:37,040
You know, they are much faster than us.
1047
01:14:37,064 --> 01:14:41,536
When the first female comes to spawn,
then they will all come together.
1048
01:14:41,560 --> 01:14:44,164
They go up, swim up,
and all the males follow.
1049
01:14:44,188 --> 01:14:46,742
You have two, three, four,
sometimes up to ten.
1050
01:14:46,766 --> 01:14:50,478
And you have to be very reactive
because this is very fast.
1051
01:14:50,820 --> 01:14:52,697
Not missing any action.
1052
01:14:54,365 --> 01:14:59,054
NARRATOR: Millions of parrotfish eggs
are released into the warm ocean currents,
1053
01:14:59,078 --> 01:15:02,832
creating the next generation
of reef saviors.
1054
01:15:08,379 --> 01:15:11,451
In discovering these spectacles
across the world,
1055
01:15:11,966 --> 01:15:16,053
our filmmakers have also given us
a valuable insight
1056
01:15:16,387 --> 01:15:19,473
into how we can help our fragile oceans.
1057
01:15:24,061 --> 01:15:26,061
With international protection,
1058
01:15:26,564 --> 01:15:30,067
more places like Palau
would be able to recover...
1059
01:15:34,530 --> 01:15:37,742
creating a healthier,
more productive ocean.
1060
01:15:40,911 --> 01:15:43,581
One full of incredible characters...
1061
01:15:44,874 --> 01:15:48,103
- (DOLPHINS CLICKING)
- ...that can continue to thrive
1062
01:15:48,127 --> 01:15:50,421
long into the future.
1063
