Would you like to inspect the original subtitles? These are the user uploaded subtitles that are being translated:
1
00:00:03,440 --> 00:00:06,879
Dolphins - the cleverest creatures in the ocean.
2
00:00:08,560 --> 00:00:10,999
Spy creatures delve into their secret lives...
3
00:00:15,480 --> 00:00:17,799
..to reveal new surprising behaviour...
4
00:00:22,560 --> 00:00:24,559
..and yet more mysterious events.
5
00:00:26,720 --> 00:00:29,399
Encounter the greatest dolphin in the ocean...
6
00:00:31,120 --> 00:00:33,239
..and discover their family secrets.
7
00:00:36,560 --> 00:00:38,799
Hitch a ride on the back of a dolphin.
8
00:00:40,480 --> 00:00:42,479
And take a leap into another world.
9
00:00:54,120 --> 00:00:57,879
In South Africa, a super pod
of common dolphins is on the move.
10
00:01:08,960 --> 00:01:12,279
Spy Dolphin joins them
and films from the camera in its eye.
11
00:01:18,880 --> 00:01:23,199
The dolphins are after a special meal,
one only served up at this time of year.
12
00:01:39,680 --> 00:01:44,079
The feast happens every winter,
but in the vast ocean, it's difficult to find.
13
00:01:48,640 --> 00:01:50,799
To track it down, they must work as a team.
14
00:01:50,960 --> 00:01:52,959
(Whistling)
15
00:02:05,400 --> 00:02:09,079
Speed is everything.
They must beat other predators to the meal.
16
00:02:14,480 --> 00:02:17,079
By working together, they gain the advantage.
17
00:02:21,520 --> 00:02:26,119
And here it is -
the greatest fish migration on the planet.
18
00:02:30,080 --> 00:02:34,759
The sardines may number millions,
but to catch them, they must still work as a team.
19
00:02:40,480 --> 00:02:43,959
They dive deep beneath the shoal
and start to herd it upwards.
20
00:02:53,720 --> 00:02:55,599
The fish stick together for safety.
21
00:02:55,760 --> 00:02:58,679
The dolphins' task
is to break down their defences.
22
00:03:01,240 --> 00:03:02,639
(Whistling)
23
00:03:09,680 --> 00:03:13,079
They use loud calls and bursts of bubbles
to help drive them.
24
00:03:15,600 --> 00:03:17,279
(Whistling and chattering)
25
00:03:23,360 --> 00:03:26,439
The shoal fragments
into more manageable bait balls.
26
00:03:27,760 --> 00:03:29,759
Now the feeding begins.
27
00:03:38,760 --> 00:03:40,759
But sardines are never eaten alone.
28
00:03:45,120 --> 00:03:47,199
Gannets have been watching from above.
29
00:03:47,360 --> 00:03:49,319
They seize the moment.
30
00:03:53,240 --> 00:03:54,719
(Screeching)
31
00:04:09,400 --> 00:04:11,599
Gannets aren't the only gatecrashers.
32
00:04:13,040 --> 00:04:15,119
Bronze whaler sharks join the party.
33
00:04:40,480 --> 00:04:42,959
The dolphins wisely beat a retreat...
34
00:04:44,280 --> 00:04:46,279
..just in the nick of time.
35
00:04:50,440 --> 00:04:52,919
A 13-metre Bryde's Whale.
36
00:05:06,360 --> 00:05:09,839
And he's not the only ocean giant
attracted by the gathering.
37
00:05:14,000 --> 00:05:16,399
The world's largest dolphin is here too...
38
00:05:20,040 --> 00:05:21,719
..the orca.
39
00:05:31,200 --> 00:05:35,239
Orcas always travel as a family
and they too rely on teamwork.
40
00:05:35,400 --> 00:05:36,879
(Whistling)
41
00:05:38,440 --> 00:05:40,439
But they aren't after the sardines.
42
00:05:41,080 --> 00:05:43,079
They're here for the dolphins.
43
00:05:59,560 --> 00:06:01,759
They dive deep to take them by surprise.
44
00:06:10,040 --> 00:06:14,479
A close shave for the dolphin...
and a disappointment for the orcas.
45
00:06:17,400 --> 00:06:20,799
But working as a family,
they will gain plenty more chances.
46
00:06:25,560 --> 00:06:29,759
In neighbouring Mozambique,
Spy Turtle is following a pod of bottlenose.
47
00:06:34,880 --> 00:06:36,879
He's one of many different spy creatures
48
00:06:37,040 --> 00:06:40,359
who have been watching how
these dolphins work together as a team.
49
00:06:45,720 --> 00:06:47,479
(Clicking)
50
00:06:50,040 --> 00:06:52,839
Spy Baby joins the underwater menagerie.
51
00:06:54,840 --> 00:06:58,719
This new remote-controlled spy creature
also has cameras for eyes.
52
00:07:01,600 --> 00:07:05,399
He's on the trail of a young male
that has just left his mother's pod.
53
00:07:14,120 --> 00:07:17,559
He's having to survive
without the support of family or friends
54
00:07:17,720 --> 00:07:20,039
and it's not something he likes very much.
55
00:07:24,280 --> 00:07:28,359
He unearths a tubeworm -
not the quality of seafood he's used to.
56
00:07:29,600 --> 00:07:31,199
(Squeaks)
57
00:07:34,400 --> 00:07:39,079
He's in need of company, and for now,
the new spy creature will do nicely.
58
00:07:43,320 --> 00:07:44,719
(Chatters)
59
00:07:44,880 --> 00:07:46,759
Spy Baby records his lonely call...
60
00:07:46,920 --> 00:07:48,599
(Whistling)
61
00:07:51,160 --> 00:07:53,039
..then plays it back to him.
62
00:07:53,200 --> 00:07:54,959
(Whistling)
63
00:08:01,840 --> 00:08:04,639
The dolphin responds with his signature whistle.
64
00:08:12,040 --> 00:08:14,399
And Spy Baby plays this back as well.
65
00:08:14,560 --> 00:08:16,199
(Whistling)
66
00:08:22,400 --> 00:08:27,279
These unique whistles are used like names,
repeating the call is a sign of friendship.
67
00:08:33,120 --> 00:08:35,119
He picks up a mangrove seed...
68
00:08:37,400 --> 00:08:39,399
..and presents it to Spy Baby.
69
00:08:42,240 --> 00:08:44,239
It's another friendly gesture.
70
00:08:48,960 --> 00:08:51,319
Offering gifts is common among dolphins,
71
00:08:51,480 --> 00:08:54,759
but Spy baby can never be
the companion he needs.
72
00:08:55,760 --> 00:08:57,079
(Squeaks)
73
00:09:08,720 --> 00:09:13,199
He must find real dolphins
if he is to thrive in this new stage of life.
74
00:09:15,240 --> 00:09:20,399
To discover more about single dolphins,
the spy team enlists some special support.
75
00:09:24,560 --> 00:09:28,759
In the Caribbean, there is a bottlenose dolphin
with a very useful talent.
76
00:09:42,920 --> 00:09:45,959
He's happy to carry tiny cameras into the wild.
77
00:09:47,840 --> 00:09:52,559
Each day, this tame dolphin
is given free rein to explore the open ocean.
78
00:09:59,000 --> 00:10:02,479
He returns when he wishes
with a recording of his adventures.
79
00:10:10,440 --> 00:10:15,239
From this unique position, it's clear
how he glides through the water with such ease.
80
00:10:26,040 --> 00:10:30,519
Powerful beats of his tail give him perfect control
as he searches for company.
81
00:10:36,840 --> 00:10:38,799
But another dolphin finds him first.
82
00:10:38,960 --> 00:10:40,519
(Whistling)
83
00:10:45,080 --> 00:10:47,399
He could hear his call from ten miles away.
84
00:10:48,760 --> 00:10:52,359
By happily swimming side-by-side,
they show they're friends.
85
00:11:02,040 --> 00:11:04,839
Only dolphins that know each other
come this close.
86
00:11:05,000 --> 00:11:06,519
(Squeaks)
87
00:11:09,640 --> 00:11:12,479
They partner up as they start looking for a meal.
88
00:11:17,360 --> 00:11:19,919
Despite the wealth of fish life on the reef,
89
00:11:20,080 --> 00:11:22,079
the dolphin has learnt to be choosy.
90
00:11:22,720 --> 00:11:25,399
Many fish are distasteful or poisonous.
91
00:11:41,400 --> 00:11:44,959
Up ahead is a barracuda - a wholesome meal.
92
00:11:55,680 --> 00:11:59,039
But it's quick and has a nasty nip.
It's not worth the trouble.
93
00:12:09,760 --> 00:12:12,439
A giant snapper presents the next opportunity.
94
00:12:15,560 --> 00:12:18,599
But it too is armed to the teeth and best avoided.
95
00:12:23,760 --> 00:12:28,039
Surprisingly, the barren seabed
offers the easiest possibilities.
96
00:12:28,560 --> 00:12:30,159
(Clicking)
97
00:12:31,960 --> 00:12:35,559
He scans it with sonar,
moving his head like a minesweeper.
98
00:12:58,000 --> 00:13:02,599
When he finds a hidden fish,
he ID's it by upping the sonar's intensity.
99
00:13:02,760 --> 00:13:04,559
(Clicking intensifies)
100
00:13:09,400 --> 00:13:11,319
A tasty titbit for all the effort.
101
00:13:14,080 --> 00:13:18,879
Single dolphins have to rely on
their personal skills and abilities for everything.
102
00:13:19,760 --> 00:13:23,079
It's a different matter
for those that hunt as a pod.
103
00:13:25,920 --> 00:13:30,039
In South Carolina,
bottlenose take teamwork to a whole new level.
104
00:13:35,400 --> 00:13:37,279
The results are spectacular.
105
00:13:41,000 --> 00:13:42,999
Fish explode onto the shore.
106
00:13:46,320 --> 00:13:48,599
They just have to be plucked from the mud.
107
00:13:56,960 --> 00:13:59,079
Spy Dolphin moves in for a closer look.
108
00:14:03,840 --> 00:14:08,439
He follows as the dolphins patrol the shallow
creeks to find yet more fish shoals.
109
00:14:10,680 --> 00:14:12,039
(Whirring)
110
00:14:14,000 --> 00:14:16,479
The technique requires close cooperation.
111
00:14:23,000 --> 00:14:27,199
But one dolphin makes the final decision,
selecting which mud bank to use.
112
00:14:34,640 --> 00:14:36,639
He then leads the charge.
113
00:14:40,920 --> 00:14:43,439
The fish leap and panic, right onto the shore.
114
00:15:00,280 --> 00:15:03,479
The dolphins may hunt like this
15 times on each low tide.
115
00:15:16,360 --> 00:15:19,279
These techniques are only known
by a few local individuals
116
00:15:19,440 --> 00:15:22,719
and they have to be learnt
by younger members of the group.
117
00:15:28,320 --> 00:15:30,799
Stranding is a serious hazard for dolphins.
118
00:15:33,760 --> 00:15:35,759
But these have mastered the knack.
119
00:15:43,400 --> 00:15:45,159
As dolphins are so intelligent,
120
00:15:45,320 --> 00:15:49,399
they can tailor the way they catch food
to exploit specific local conditions.
121
00:16:52,880 --> 00:16:53,959
(Sonar clicking)
122
00:16:54,120 --> 00:16:59,199
In Mozambique, the dolphin that's left his pod
still cuts a lonely figure.
123
00:17:08,800 --> 00:17:11,319
His task now is to find a companion.
124
00:17:12,920 --> 00:17:15,239
And Spy Baby doesn't measure up to the job.
125
00:17:16,080 --> 00:17:17,719
(Clicking)
126
00:17:28,440 --> 00:17:31,199
But Spy Baby soon spots someone who might.
127
00:17:35,520 --> 00:17:37,519
But it's not a bottlenose.
128
00:17:42,640 --> 00:17:46,999
It's a rare humpback dolphin -
a different species entirely.
129
00:17:54,880 --> 00:17:58,279
Regardless, the young bottlenose
still seems interested.
130
00:18:02,680 --> 00:18:05,799
And something extraordinary
appears to be happening.
131
00:18:06,800 --> 00:18:08,799
They seem to be making friends.
132
00:18:14,600 --> 00:18:18,679
This is the first time such a peculiar partnership
has ever been filmed.
133
00:18:29,040 --> 00:18:32,759
They strengthen their relationship
by swimming close together.
134
00:18:36,480 --> 00:18:39,959
It may not be a match made in heaven,
but at least it's company.
135
00:18:51,320 --> 00:18:55,639
Orcas are never lonely -
their families stay together for life.
136
00:19:06,760 --> 00:19:10,839
British Colombia has among
the highest number of orca pods in the world.
137
00:19:16,560 --> 00:19:18,559
The family is led by the eldest female,
138
00:19:18,720 --> 00:19:21,919
while her daughters and granddaughters
follow behind.
139
00:19:30,160 --> 00:19:33,359
Unlike most dolphins,
the males stay with their family.
140
00:19:36,920 --> 00:19:39,719
His dorsal fin is nearly two metres high.
141
00:19:46,880 --> 00:19:48,759
They stay together for life
142
00:19:48,920 --> 00:19:52,679
and any hunting knowledge gained
is kept exclusively within the group.
143
00:19:56,000 --> 00:19:58,879
A calf learns the family secrets
from an early age.
144
00:19:59,520 --> 00:20:01,679
What he knows depends on which pod he's in.
145
00:20:07,440 --> 00:20:09,559
This pod specialises in hunting fish.
146
00:20:11,880 --> 00:20:15,479
And as salmon migrate into the bay,
the whales are in for a treat.
147
00:20:18,360 --> 00:20:23,079
The orcas know just how to catch them
and stealth is not required.
148
00:20:24,360 --> 00:20:26,359
They rely on shock and awe.
149
00:20:28,520 --> 00:20:30,399
They make as much noise as possible,
150
00:20:30,560 --> 00:20:33,159
slapping the water
with their two-metre wide tails.
151
00:20:37,480 --> 00:20:39,479
(Water crashes)
152
00:20:40,800 --> 00:20:43,159
The shockwaves stun or disorientate the fish.
153
00:20:45,880 --> 00:20:47,959
And breaching adds to the confusion.
154
00:20:52,120 --> 00:20:55,439
They then charge into the shoal,
knocking the fish for six.
155
00:21:03,880 --> 00:21:06,439
Each orca must catch 50 salmon a day.
156
00:21:07,280 --> 00:21:10,279
And their group skills
make sure that none go hungry.
157
00:21:17,400 --> 00:21:20,599
Another nearby pod
favours completely different food.
158
00:21:25,280 --> 00:21:27,999
They specialise in catching dolphins and seals.
159
00:21:33,280 --> 00:21:38,279
They've acquired a different set of skills geared
to outsmarting their quick-thinking prey.
160
00:21:48,200 --> 00:21:50,319
They spot their food by "Spy Hopping".
161
00:21:57,080 --> 00:21:58,959
A wake may be the only sign.
162
00:22:00,080 --> 00:22:01,559
They check again.
163
00:22:08,080 --> 00:22:09,999
It's just what they've been looking for.
164
00:22:16,200 --> 00:22:19,279
Dall's Porpoises -
the fastest dolphins in the ocean.
165
00:22:20,680 --> 00:22:23,599
They reach speeds of over 35 miles per hour.
166
00:22:31,440 --> 00:22:35,639
Orcas nearly match them for speed, but the
porpoises are much more manoeuvrable.
167
00:22:41,360 --> 00:22:44,719
As the orcas dive, they switch to stealth mode...
168
00:22:48,120 --> 00:22:50,119
..and try to sneak up undetected.
169
00:22:52,520 --> 00:22:55,039
But the porpoises just keep on accelerating.
170
00:23:05,200 --> 00:23:07,679
The orcas' endurance is tested to the limit.
171
00:23:13,040 --> 00:23:15,039
And the porpoises race to freedom.
172
00:23:19,360 --> 00:23:21,559
The orcas look for far easier prey.
173
00:23:23,680 --> 00:23:26,159
A lone sea lion is an unsuspecting target.
174
00:23:56,000 --> 00:23:57,959
Despite living close to one another,
175
00:23:58,120 --> 00:24:02,039
the pods that hunt mammals
never interact with those that catch fish.
176
00:24:04,360 --> 00:24:09,039
They not only pursue different prey,
they even have different calls and dialects.
177
00:24:21,440 --> 00:24:25,519
Back in Mozambique, another
spy creature joins the surveillance team.
178
00:24:27,040 --> 00:24:29,039
This is Spy Puffer,
179
00:24:29,200 --> 00:24:31,799
a puffer fish with a camera in its mouth.
180
00:24:33,640 --> 00:24:37,399
He immediately starts filming the young male
and his humpback friend.
181
00:24:45,200 --> 00:24:47,399
They seem to be getting along just fine.
182
00:24:53,120 --> 00:24:57,079
A second puffer fish joins -
this one has cameras for eyes.
183
00:24:59,320 --> 00:25:01,199
They make a great double act.
184
00:25:01,360 --> 00:25:03,559
One films forwards, the other sideways.
185
00:25:15,240 --> 00:25:17,239
They immediately prove popular!
186
00:25:25,800 --> 00:25:27,119
(Whirring)
187
00:25:27,280 --> 00:25:29,959
Close by, Spy Baby
has found yet more dolphins.
188
00:25:31,760 --> 00:25:35,439
It's a gang of young males
that have also just left their mothers.
189
00:25:40,800 --> 00:25:44,399
They seem totally unfazed
by their first meeting with Spy Baby.
190
00:25:47,880 --> 00:25:49,879
(Chattering and squeaking)
191
00:25:55,680 --> 00:26:00,079
These young males hang out together,
both for company and to share knowledge.
192
00:26:01,360 --> 00:26:06,159
The young bottlenose may have made a friend,
but it's the wisdom of the crowd he needs.
193
00:26:07,640 --> 00:26:11,319
He cautiously approaches the gang
with the humpback by his side.
194
00:26:16,160 --> 00:26:20,239
He whistles out with his name,
but there's no guarantee he'll be accepted,
195
00:26:20,400 --> 00:26:22,799
especially with his strange friend in tow.
196
00:26:26,080 --> 00:26:29,759
The humpback stays close
as the bottlenose tries to join the pod.
197
00:26:33,720 --> 00:26:36,119
He's seeking reassurance from his friend.
198
00:26:45,480 --> 00:26:50,239
A pod doesn't accept newcomers willingly -
even those of the same species.
199
00:26:51,920 --> 00:26:54,399
A dolphin starts to drive the humpback away.
200
00:26:55,240 --> 00:26:57,039
(Chattering and whistling)
201
00:26:57,680 --> 00:26:59,119
(Squeaks)
202
00:26:59,720 --> 00:27:02,919
And anyway, humpbacks tend to prefer
their own company.
203
00:27:06,680 --> 00:27:11,359
As he turns to leave, his bottlenose friend
must decide whether to stay orjoin him.
204
00:27:15,960 --> 00:27:19,439
But to the bottlenose,
it's clear where his choice should be.
205
00:27:20,920 --> 00:27:26,119
As the humpback returns to a solitary life,
his friend chances his luck with the motley crew.
206
00:27:31,640 --> 00:27:37,079
The pod has a strong hierarchy but he has
an unusual method to wheedle his way in.
207
00:27:40,240 --> 00:27:41,719
(Chattering)
208
00:27:45,880 --> 00:27:50,799
He begins to act like a female -
deploying feminine charm to win them over.
209
00:28:00,360 --> 00:28:02,359
It seems to be working.
210
00:28:13,040 --> 00:28:15,039
They even perform mating rituals.
211
00:28:35,440 --> 00:28:38,919
By discovering his feminine side,
he's gradually accepted.
212
00:28:42,400 --> 00:28:46,919
Every male undergoes this initiation rite
before he is allowed to join the gang.
213
00:28:51,880 --> 00:28:56,399
This is his new family now and he'll soon
be party to everything they know.
214
00:29:00,840 --> 00:29:04,119
Such strange rites of passage
have never been filmed before
215
00:29:04,280 --> 00:29:07,959
and have previously been
mistaken for males attacking females.
216
00:29:10,360 --> 00:29:14,479
In other parts of the world,
more strange rituals are still being discovered.
217
00:29:16,960 --> 00:29:19,319
Recently, in Shark Bay, Western Australia,
218
00:29:19,480 --> 00:29:23,719
some bottlenose dolphins have taken
to wearing what look like hats.
219
00:29:28,840 --> 00:29:32,559
They're actually sea sponges,
which they balance on their noses.
220
00:29:37,480 --> 00:29:40,399
This is the first time
this behaviour has been filmed
221
00:29:40,560 --> 00:29:43,359
but the reason they carry them
remains a mystery.
222
00:29:50,200 --> 00:29:55,079
One thought is that they use them to protect
their noses as they root around in the sand.
223
00:30:03,040 --> 00:30:05,719
But some look a bit big for the job!
224
00:30:17,120 --> 00:30:21,599
As they live in such cloudy water,
the real reason has yet to be confirmed.
225
00:30:26,720 --> 00:30:28,519
(Blows air)
226
00:30:31,800 --> 00:30:35,679
Sometimes...
mysteries just add to an animal's intrigue.
227
00:30:39,120 --> 00:30:44,439
Just a few miles away, the unique behaviour
of another bottlenose pod is better understood.
228
00:30:49,720 --> 00:30:52,199
Each day they enter this shallow bay.
229
00:30:54,200 --> 00:30:56,199
(Chatter)
230
00:30:58,800 --> 00:31:01,799
They seek the fish
that gather around the shoreline.
231
00:31:03,760 --> 00:31:09,319
As the fish dart away they instinctively head to
the shore, where it's too shallow for dolphins.
232
00:31:12,600 --> 00:31:15,399
But this is all part of the dolphins' strategy.
233
00:31:20,680 --> 00:31:23,679
Fish that make a break for it
are chased right back.
234
00:31:32,600 --> 00:31:35,759
As usual, the young are watching and learning.
235
00:31:43,040 --> 00:31:45,559
The fish soon fringe the shallows.
236
00:31:45,720 --> 00:31:48,839
But they've been lulled into
a false sense of security.
237
00:31:56,080 --> 00:32:00,999
The dolphin now steps on the accelerator,
powering into the dangerously shallow water.
238
00:32:06,440 --> 00:32:10,399
The sudden turn of speed
raises her back clean out of the water.
239
00:32:15,160 --> 00:32:19,039
A few thrusts from the tail
and she hydroplanes across the surface,
240
00:32:19,200 --> 00:32:21,599
covering ten metres in less than a second.
241
00:32:26,800 --> 00:32:30,639
Using this technique,
she easily outpaces the surprised fish
242
00:32:30,800 --> 00:32:32,999
and also avoids becoming stranded.
243
00:32:43,800 --> 00:32:46,839
It's a skill known only by
the dolphins of Shark Bay.
244
00:33:38,800 --> 00:33:40,399
(Gulls cry)
245
00:33:40,560 --> 00:33:46,039
In South Carolina, some bottlenose pods
have found a far easier way to get a meal.
246
00:33:47,160 --> 00:33:50,839
They simply learn the routines
of the local shrimping boats.
247
00:33:55,880 --> 00:33:59,959
When their nets are ready to be hauled,
the dolphins rush out to join them.
248
00:34:01,800 --> 00:34:05,039
And grab any dead or injured fish
that fall through.
249
00:34:08,320 --> 00:34:11,119
But sometimes
even that much effort's not required.
250
00:34:14,800 --> 00:34:20,119
The unwanted catch is thrown back into the sea
and into the mouths of the waiting dolphins.
251
00:34:26,000 --> 00:34:28,279
It's the ultimate breakfast buffet.
252
00:34:41,040 --> 00:34:43,319
Dolphins may be incredibly inventive,
253
00:34:43,480 --> 00:34:46,519
but they are also clever enough
to grab a takeaway when they can.
254
00:34:47,000 --> 00:34:51,239
They are ever adaptable,
constantly watching and learning new skills.
255
00:34:54,160 --> 00:34:57,959
In Mozambique, the young bottlenose
has been in the gang for many weeks.
256
00:35:00,200 --> 00:35:03,479
And from them has picked up
many new talents along the way.
257
00:35:05,000 --> 00:35:07,119
He's also found a new friend.
258
00:35:09,840 --> 00:35:12,519
Most males have a best mate within a pod.
259
00:35:14,320 --> 00:35:17,279
Once formed, this bromance can last a lifetime.
260
00:35:26,600 --> 00:35:29,719
As ever, Spy Creatures watch their every move.
261
00:35:34,680 --> 00:35:37,319
The mock turtle is already proving a hit.
262
00:35:38,600 --> 00:35:40,599
And so are the puffers.
263
00:35:45,160 --> 00:35:48,479
The young male gives his newfound friend
a guided tour.
264
00:35:58,440 --> 00:36:01,239
(Squeaking and clicking)
265
00:36:03,640 --> 00:36:05,799
The pair are becoming inseparable.
266
00:36:13,040 --> 00:36:16,959
The reef is a rich stomping ground
for these teenage tearaways.
267
00:36:23,800 --> 00:36:26,479
The young male learnt most of his skills
from his mother.
268
00:36:26,640 --> 00:36:30,439
But he's making a whole new set of discoveries
with his latest pals.
269
00:36:38,440 --> 00:36:43,199
A real puffer fish offers the chance
for bored teenagers to have some fun.
270
00:36:56,800 --> 00:37:00,079
He tries to hide, but he won't get off that lightly.
271
00:37:02,040 --> 00:37:04,679
His next defence is to inflate like a ball.
272
00:37:07,600 --> 00:37:09,599
Now the game can really begin.
273
00:37:20,360 --> 00:37:22,719
Playing catch is a great pastime.
274
00:37:27,160 --> 00:37:30,279
They take turns to carry
and pass it between each other.
275
00:37:42,440 --> 00:37:45,999
But something far more extraordinary
seems to be happening.
276
00:37:48,400 --> 00:37:51,599
When attacked puffer fish release a neurotoxin.
277
00:37:53,560 --> 00:37:59,279
In high doses it can kill,
but in small doses it has a narcotic effect.
278
00:38:05,400 --> 00:38:07,719
It seems to be affecting the dolphins.
279
00:38:18,400 --> 00:38:21,999
They appear totally blissed out
by the whole experience.
280
00:38:33,000 --> 00:38:37,559
And remarkably,
all take turns in passing the puffer around.
281
00:38:42,960 --> 00:38:48,679
This is the first time that apparent recreational
drug use has been documented in dolphins.
282
00:39:01,280 --> 00:39:04,599
With the dolphins otherwise engaged,
the puffer deflates.
283
00:39:05,120 --> 00:39:07,119
He's free to go on his way.
284
00:39:08,720 --> 00:39:12,399
It looks like they will be distracted
for quite some time.
285
00:39:24,240 --> 00:39:25,399
Back in the Caribbean,
286
00:39:25,560 --> 00:39:29,679
the camera dolphin shows just how much
he interacts with other dolphins.
287
00:39:34,480 --> 00:39:36,359
If another dolphin calls...
288
00:39:36,960 --> 00:39:38,999
(Whistling)
289
00:39:39,160 --> 00:39:41,159
..he immediately answers.
290
00:39:42,880 --> 00:39:45,719
(Chatter and whistling)
291
00:39:48,000 --> 00:39:50,079
He uses dozens of different calls,
292
00:39:50,240 --> 00:39:54,279
telling all the dolphins in the local area
where he is and what he's doing.
293
00:39:55,840 --> 00:39:57,559
(Bellow-like call)
294
00:39:57,720 --> 00:40:01,319
The lips of the blowhole act like a mouth,
adjusting the sound.
295
00:40:01,480 --> 00:40:03,479
(Clicking)
296
00:40:10,400 --> 00:40:12,479
Before long his calls are answered.
297
00:40:17,920 --> 00:40:19,799
(Squeaking)
298
00:40:19,960 --> 00:40:23,159
In murky water
it's the only way they can stay in contact.
299
00:40:30,480 --> 00:40:36,039
Different pods have different dialects or accents,
and each sound has a specific meaning.
300
00:40:36,200 --> 00:40:38,199
(Chatter)
301
00:40:52,960 --> 00:40:56,479
They hear a far greater range of frequencies
than we can,
302
00:40:56,640 --> 00:40:59,839
so we can only eavesdrop
on a fraction of their conversations.
303
00:41:01,360 --> 00:41:03,759
(Chatter and whistling)
304
00:41:21,000 --> 00:41:23,599
Blasts of bubbles add emphasis
to what he's saying.
305
00:41:31,760 --> 00:41:34,759
And special calls are reserved
for the opposite sex.
306
00:41:36,160 --> 00:41:38,359
Some of their sounds are quite bizarre.
307
00:41:38,520 --> 00:41:40,639
(High-pitched yelping)
308
00:41:40,800 --> 00:41:42,799
(Bellow-like call)
309
00:41:42,960 --> 00:41:46,799
This is actually a love song
and it seems to be working.
310
00:41:50,640 --> 00:41:52,839
The females allow him to approach...
311
00:41:55,360 --> 00:41:57,359
..but not for long!
312
00:41:58,040 --> 00:42:00,319
(High-pitched yelping)
313
00:42:00,480 --> 00:42:01,919
(Bellow-like call)
314
00:42:07,880 --> 00:42:11,559
He catches up
and this time the females wait for him.
315
00:42:19,760 --> 00:42:21,759
He checks her out.
316
00:42:24,160 --> 00:42:27,039
But she's still nursing, so of no interest at all.
317
00:42:36,560 --> 00:42:38,599
(Whines)
318
00:42:38,760 --> 00:42:40,759
He takes a deep breath.
319
00:42:43,000 --> 00:42:46,479
Time for a well-earned rest after all his efforts.
320
00:42:52,960 --> 00:42:54,959
He starts to go to sleep.
321
00:42:59,000 --> 00:43:02,799
And the fish play dare
around their snoozing predator.
322
00:43:07,600 --> 00:43:10,079
Dolphins have a bizarre way of sleeping.
323
00:43:10,800 --> 00:43:13,559
Each half of their brain rests in turn,
324
00:43:13,720 --> 00:43:17,559
allowing the other half to stay awake
and alert to danger.
325
00:43:25,120 --> 00:43:29,239
In Mozambique,
the male pod is still very much awake.
326
00:43:31,800 --> 00:43:34,479
And Spy Squid is on filming duty.
327
00:43:35,600 --> 00:43:37,919
He's found a hawksbill turtle.
328
00:43:45,560 --> 00:43:47,559
Squid takes a closer look.
329
00:44:02,640 --> 00:44:04,559
But he needs to be careful.
330
00:44:10,400 --> 00:44:13,199
A potato cod has him in his sights.
331
00:44:21,760 --> 00:44:23,759
Squid beats a retreat.
332
00:44:25,000 --> 00:44:26,999
And then goes back to work.
333
00:44:30,960 --> 00:44:34,559
It's not a moment too soon -
the pod is chattering with excitement.
334
00:44:34,720 --> 00:44:36,719
(Chatter)
335
00:44:40,520 --> 00:44:45,599
The two friends stick close together
as the reason for their concern becomes clear.
336
00:44:46,000 --> 00:44:47,999
(Whistling)
337
00:44:50,400 --> 00:44:53,199
Another gang of males is approaching.
338
00:44:57,200 --> 00:45:02,959
The home pod takes up defensive positions
as the two groups square up for a territorial fight.
339
00:45:05,040 --> 00:45:07,279
Then...it all kicks off.
340
00:45:07,560 --> 00:45:10,559
(Chatter and whistling)
341
00:45:28,000 --> 00:45:32,119
When two pods come together
the existing hierarchy can break down.
342
00:45:38,960 --> 00:45:41,479
It's how new groups and alliances are formed.
343
00:46:08,800 --> 00:46:12,479
The pair decide that, for now,
they're safer on their own.
344
00:46:16,760 --> 00:46:18,879
They leave the rest to fight it out.
345
00:46:22,320 --> 00:46:24,839
They may rejoin the pod
when things calm down.
346
00:46:30,960 --> 00:46:36,919
Bottlenose can choose when to be social or
alone, but some dolphins don't have this option.
347
00:46:38,480 --> 00:46:43,439
It's late summer in Patagonia and the beaches
are packed with breeding sea lions.
348
00:46:46,440 --> 00:46:48,519
(Barking)
349
00:46:48,680 --> 00:46:54,079
And as their young are about to enter the water,
an orca pod arrives like clockwork.
350
00:46:58,160 --> 00:47:00,999
They are a family
that has hunted here for generations,
351
00:47:01,160 --> 00:47:04,479
and they have devised
a spectacular way to get a meal.
352
00:47:11,640 --> 00:47:15,839
The adult sea lions are wise to their plan
and usually see them coming.
353
00:47:37,680 --> 00:47:40,599
But the new pups aren't so smart.
354
00:47:45,200 --> 00:47:49,999
The orcas patrol the surf zone
waiting for one of them to make a mistake.
355
00:47:54,040 --> 00:47:56,759
Sooner or later they have to enter the water.
356
00:47:58,720 --> 00:48:01,199
And this is when the orcas strike.
357
00:48:03,800 --> 00:48:06,919
A near miss,
but she'll have plenty of other chances.
358
00:48:09,200 --> 00:48:11,199
(Barking and grunting)
359
00:48:14,480 --> 00:48:19,839
But when it comes to catching sea lion pups,
there is one orca better than all the rest.
360
00:48:45,000 --> 00:48:50,199
The expert is a 50-year-old-male,
who's hunted these waters all his life.
361
00:48:53,160 --> 00:48:58,119
The technique is a family tradition,
and training starts at an early age.
362
00:49:07,800 --> 00:49:11,199
They have been hunting sea lions like this
for generations.
363
00:49:25,320 --> 00:49:31,319
Each orca uses their own subtle variations,
but none is as accomplished as the old male.
364
00:49:36,280 --> 00:49:37,999
(Sea lion honks)
365
00:49:38,160 --> 00:49:40,919
This should be suicidal for a ten-ton Orca.
366
00:49:41,080 --> 00:49:43,919
Around the world
hundreds die from stranding each year.
367
00:49:48,240 --> 00:49:50,279
Even he seems to be struggling.
368
00:49:53,560 --> 00:49:55,839
But he has survived for half a century.
369
00:49:56,000 --> 00:49:57,999
He clearly knows what he's doing.
370
00:50:01,080 --> 00:50:03,639
He's never left high and dry.
371
00:50:11,560 --> 00:50:13,759
Even in a pod where skills are shared,
372
00:50:13,920 --> 00:50:17,119
there is always one individual
who outshines the rest.
373
00:50:47,240 --> 00:50:49,679
Despite the value of working in a pod,
374
00:50:49,840 --> 00:50:55,239
in Mozambique, the two dolphin friends discover
there can be advantages to being independent.
375
00:50:58,680 --> 00:51:03,439
They meet a group of females and are
already faring better for being on their own.
376
00:51:06,600 --> 00:51:10,959
A female has even started to show
some interest: flirting with the young male.
377
00:51:11,120 --> 00:51:13,159
(Chatter)
378
00:51:21,720 --> 00:51:25,039
Things are going well,
but the pair won't be alone.
379
00:51:29,160 --> 00:51:32,279
His best friend plays gooseberry
in this new romance.
380
00:51:47,000 --> 00:51:51,559
Not put off, the female shows her interest
by some seductive moves.
381
00:51:55,800 --> 00:51:59,439
She also blushes pink - a total giveaway!
382
00:52:03,800 --> 00:52:06,599
And there's nothing subtle about her fin slaps.
383
00:52:14,000 --> 00:52:18,559
Yet all the time the courting pair
are accompanied by the young male's friend.
384
00:52:19,800 --> 00:52:24,999
But this best mate has a job to do, watching his
friend's back while he's otherwise engaged.
385
00:52:25,640 --> 00:52:28,559
He chases off other males that might muscle in.
386
00:52:33,560 --> 00:52:36,719
In dolphin world it's what best friends are for.
387
00:52:42,120 --> 00:52:46,199
And to guarantee success the courting male
gathers a bouquet of seaweed
388
00:52:46,360 --> 00:52:48,359
for the new love of his life.
389
00:53:52,680 --> 00:53:57,319
As the happy couple play with the garland
their relationship is complete.
390
00:54:08,400 --> 00:54:13,679
It seems that the friend isn't doing too badly
either - he's found himself a girlfriend too.
391
00:54:17,800 --> 00:54:20,599
It's a match made in underwater heaven.
392
00:54:46,160 --> 00:54:50,519
Back in the Caribbean the camera dolphin
is doing what dolphins love the most -
393
00:54:50,680 --> 00:54:52,679
racing through the waves.
394
00:55:00,760 --> 00:55:06,799
Like all the dolphins we've seen, he has taken
us on an incredible journey into his secret world.
395
00:55:12,600 --> 00:55:16,679
He then treats us to something extraordinary.
He barrel rolls with joy.
396
00:55:20,200 --> 00:55:25,479
Then, for the first time...
the view from his back as he leaps.
397
00:55:40,200 --> 00:55:43,119
Dolphins are the cleverest creatures
in the ocean.
398
00:55:47,120 --> 00:55:50,479
And as they have shown us,
they certainly have the most fun.
399
00:57:12,480 --> 00:57:16,159
Out on the reef,
Spy Squid goes on one last adventure.
400
00:57:17,920 --> 00:57:21,999
He soon meets his arch-enemy:
the potato cod.
401
00:57:24,640 --> 00:57:26,639
Anotherjoins...
402
00:57:30,800 --> 00:57:34,039
And yet another. This doesn't look good.
403
00:57:38,000 --> 00:57:41,119
He valiantly keeps filming
but he's completely surrounded.
404
00:57:59,680 --> 00:58:02,319
And then...catastrophe.
405
00:58:21,120 --> 00:58:24,039
Among the fishes he rests in pieces.
406
00:58:25,000 --> 00:58:29,399
But like all the Spy Creatures...his job is done.
