1
00:00:05,806 --> 00:00:09,675
Africa-- a continent of brutal predators
2
00:00:09,677 --> 00:00:13,412
and wily prey.
3
00:00:13,414 --> 00:00:16,181
They compete against each other to survive
4
00:00:16,183 --> 00:00:21,020
but pull together for real success,
5
00:00:21,022 --> 00:00:25,457
with millions of years to perfect team strategy,
6
00:00:25,459 --> 00:00:27,292
pack predation,
7
00:00:27,294 --> 00:00:30,396
prey annihilation.
8
00:00:30,398 --> 00:00:33,465
From the hungriest of big cats
9
00:00:33,467 --> 00:00:36,101
to the angriest of big cows,
10
00:00:36,103 --> 00:00:40,839
these are the coordinated attacks of Africa's deadliest.
11
00:00:40,841 --> 00:00:44,009
(roaring)
12
00:00:45,613 --> 00:00:47,379
One of Africa's deadliest ranks
13
00:00:47,381 --> 00:00:50,215
among the most feared predators in the world.
14
00:00:50,217 --> 00:00:55,421
(music)
15
00:00:55,423 --> 00:00:58,457
Twice the muscle of a heavyweight body builder,
16
00:00:58,459 --> 00:01:02,528
yet capable of speeds of over 40 miles per hour,
17
00:01:02,530 --> 00:01:06,865
lions can kill virtually any large mammal in Africa.
18
00:01:06,867 --> 00:01:09,735
(growling)
19
00:01:12,773 --> 00:01:16,275
Lions can tackle these big herbivores
20
00:01:16,277 --> 00:01:20,379
because only lions have the size, power, weaponry,
21
00:01:20,381 --> 00:01:22,481
and group strength to kill them.
22
00:01:22,483 --> 00:01:29,354
(music)
23
00:01:29,356 --> 00:01:32,991
Jaws that can pierce through a car tire,
24
00:01:32,993 --> 00:01:36,195
retractable claws that fly open like switchblades
25
00:01:36,197 --> 00:01:40,099
to slice through two-inch-thick hides,
26
00:01:40,101 --> 00:01:41,867
and a lightweight skeleton
27
00:01:41,869 --> 00:01:48,006
that supports extra muscle mass for superhuman power--
28
00:01:48,008 --> 00:01:51,443
these weapons combine to make individual lions
29
00:01:51,445 --> 00:01:56,014
one of the most powerful predators on dry land.
30
00:01:56,016 --> 00:01:59,818
Yet even these mighty predators have a nemesis...
31
00:02:02,189 --> 00:02:07,226
...a prey animal famous for turning a chase into an attack.
32
00:02:07,228 --> 00:02:13,565
(music)
33
00:02:13,567 --> 00:02:20,205
(lowing)
34
00:02:20,207 --> 00:02:25,144
(music)
35
00:02:26,780 --> 00:02:28,714
The Cape buffalo.
36
00:02:28,716 --> 00:02:30,749
(grunting)
37
00:02:30,751 --> 00:02:33,085
Predation has shaped these wild cows
38
00:02:33,087 --> 00:02:38,157
into one of Africa's most aggressive herbivores.
39
00:02:38,159 --> 00:02:40,959
The half-ton goliaths are quick to charge
40
00:02:40,961 --> 00:02:43,128
and famous for goring their enemies
41
00:02:43,130 --> 00:02:45,764
with their deadly two-foot horns.
42
00:02:54,775 --> 00:02:56,241
When it comes to predators,
43
00:02:56,243 --> 00:02:59,978
the buffalo's best defense is attack.
44
00:02:59,980 --> 00:03:03,649
(music)
45
00:03:03,651 --> 00:03:08,887
(music)
46
00:03:08,889 --> 00:03:11,757
For lion prides to take on these fierce beasts,
47
00:03:11,759 --> 00:03:16,495
they need the strength of numbers and a fool-proof plan.
48
00:03:20,367 --> 00:03:23,368
Today, they have both.
49
00:03:27,274 --> 00:03:31,910
This pride has driven their victim into the perfect trap.
50
00:03:35,449 --> 00:03:37,716
Stuck in a Luangwa water hole,
51
00:03:37,718 --> 00:03:42,321
this buffalo has nowhere left to run.
52
00:03:42,323 --> 00:03:48,093
The lions have blocked every exit.
53
00:03:48,095 --> 00:03:52,831
The bull can kill with a blow of his horns.
54
00:03:52,833 --> 00:03:57,369
The lions can't tackle him head-on.
55
00:03:57,371 --> 00:04:00,906
Instead, they'll just wear him down.
56
00:04:00,908 --> 00:04:05,944
(music)
57
00:04:05,946 --> 00:04:12,384
(music)
58
00:04:12,386 --> 00:04:14,720
In the water, fear and cold
59
00:04:14,722 --> 00:04:18,323
sap the strength the bull needs to defend himself.
60
00:04:29,937 --> 00:04:34,973
The lions just need to hold the bank and wait.
61
00:04:38,846 --> 00:04:43,215
The adult lionesses conserve their energy.
62
00:04:43,217 --> 00:04:47,519
They let the sub-adults taunt the victim.
63
00:04:47,521 --> 00:04:50,922
Their expertise will be needed after dark.
64
00:04:50,924 --> 00:04:57,729
(music)
65
00:05:06,607 --> 00:05:08,874
By nightfall, they've maneuvered the bull
66
00:05:08,876 --> 00:05:12,678
out of the water hole, and he's exhausted.
67
00:05:14,915 --> 00:05:19,251
He's weak and bleeding from dozens of small wounds.
68
00:05:19,253 --> 00:05:23,522
(music)
69
00:05:23,524 --> 00:05:29,094
The lionesses step up for the coup de grace.
70
00:05:29,096 --> 00:05:32,531
The young males hold the perimeter to prevent escape.
71
00:05:36,537 --> 00:05:38,570
Like clowns at a rodeo,
72
00:05:38,572 --> 00:05:42,040
the lionesses taunt the bull to draw his attention,
73
00:05:42,042 --> 00:05:44,943
but stay just out of range of his horns.
74
00:05:48,582 --> 00:05:52,884
The distraction allows another female to attack from behind.
75
00:05:57,291 --> 00:05:59,224
(lows)
76
00:06:02,629 --> 00:06:06,598
As the bull weakens, the youngsters join the fight.
77
00:06:09,603 --> 00:06:11,103
(lows)
78
00:06:13,040 --> 00:06:18,009
The lioness on top bites into his spine to disable his legs,
79
00:06:18,011 --> 00:06:23,081
as the rest target his tendons.
80
00:06:23,083 --> 00:06:26,251
(bellows)
81
00:06:26,253 --> 00:06:30,756
Pain and exhaustion win over at last.
82
00:06:30,758 --> 00:06:33,725
The bull can fight no more.
83
00:06:38,432 --> 00:06:43,235
(bellowing)
84
00:06:43,237 --> 00:06:47,239
Suffocation brings the battle to a merciful end.
85
00:06:47,241 --> 00:06:54,045
(growling)
86
00:06:54,047 --> 00:06:58,216
The reward is worth the risk.
87
00:06:58,218 --> 00:07:04,856
The bull's giant carcass will feed the pride for a week.
88
00:07:04,858 --> 00:07:06,191
(growling)
89
00:07:06,193 --> 00:07:13,098
(growling)
90
00:07:13,100 --> 00:07:16,201
Buffalo are one of lions' primary prey,
91
00:07:16,203 --> 00:07:20,972
but hunts aren't always this successful.
92
00:07:20,974 --> 00:07:25,477
Numbers are the swing vote between these enemies.
93
00:07:25,479 --> 00:07:30,015
And when the buffalo have backup, the odds can change.
94
00:07:38,625 --> 00:07:40,725
Some of the largest buffalo herds in Africa
95
00:07:40,727 --> 00:07:42,561
roam the Luangwa Valley.
96
00:07:42,563 --> 00:07:47,799
(lowing)
97
00:07:47,801 --> 00:07:52,737
Among their ranks are hundreds of weak, vulnerable calves,
98
00:07:52,739 --> 00:07:56,975
but they are guarded by mothers who will kill to protect them.
99
00:08:05,018 --> 00:08:08,353
When threatened, the herd moves in a tight convoy.
100
00:08:10,591 --> 00:08:12,757
The adult females hold the front line
101
00:08:12,759 --> 00:08:14,459
and look out for danger,
102
00:08:14,461 --> 00:08:17,696
to protect the weaker animals at the center.
103
00:08:21,869 --> 00:08:24,569
To breach the solid wall of angry muscle,
104
00:08:24,571 --> 00:08:27,572
lions must risk their lives.
105
00:08:27,574 --> 00:08:34,212
(music)
106
00:08:34,214 --> 00:08:39,584
(music)
107
00:08:39,586 --> 00:08:46,124
(bellowing)
108
00:08:46,126 --> 00:08:48,793
If a lion gets cornered by the buffaloes,
109
00:08:48,795 --> 00:08:51,630
it's in deep trouble.
110
00:08:51,632 --> 00:08:52,764
(lowing)
111
00:08:55,435 --> 00:08:58,803
A tree offers temporary refuge,
112
00:08:58,805 --> 00:09:02,040
but lions are awkward climbers.
113
00:09:02,042 --> 00:09:05,710
The herd won't leave until they've drawn blood.
114
00:09:05,712 --> 00:09:12,617
(music)
115
00:09:12,619 --> 00:09:15,220
(music)
116
00:09:15,222 --> 00:09:17,956
The lion loses its fight with gravity,
117
00:09:17,958 --> 00:09:22,127
above a sea of enraged buffalo.
118
00:09:22,129 --> 00:09:28,833
(lowing)
119
00:09:28,835 --> 00:09:32,871
(lowing)
120
00:09:32,873 --> 00:09:39,010
(lowing)
121
00:09:39,012 --> 00:09:42,080
The herd shows no mercy.
122
00:09:42,082 --> 00:09:44,115
This is a game of survival,
123
00:09:44,117 --> 00:09:48,687
and every lion eliminated may be a buffalo saved.
124
00:09:55,429 --> 00:09:59,564
(music)
125
00:09:59,566 --> 00:10:02,133
Southern Africa's vast grasslands are home to one
126
00:10:02,135 --> 00:10:06,471
of Africa's tightest and toughest gangs of predators--
127
00:10:06,473 --> 00:10:08,006
hyenas.
128
00:10:08,008 --> 00:10:12,043
(music)
129
00:10:12,045 --> 00:10:18,683
(music)
130
00:10:18,685 --> 00:10:24,255
The females are boss in these carnivore clans.
131
00:10:24,257 --> 00:10:28,493
Even the lowest female outranks the highest male.
132
00:10:28,495 --> 00:10:34,399
(music)
133
00:10:34,401 --> 00:10:39,771
This young male left his birth clan, as all adult males do.
134
00:10:39,773 --> 00:10:42,040
Now he joins a new pack
135
00:10:42,042 --> 00:10:44,809
on the bottom rung of the social ladder.
136
00:10:44,811 --> 00:10:48,480
(laughing)
137
00:10:48,482 --> 00:10:53,251
(screaming)
138
00:10:53,253 --> 00:10:55,220
So-called laughing hyenas have
139
00:10:55,222 --> 00:10:58,023
one of the strongest bites on the planet,
140
00:10:58,025 --> 00:11:01,393
and they'll haze this newcomer without mercy.
141
00:11:01,395 --> 00:11:07,799
(screaming)
142
00:11:07,801 --> 00:11:14,773
(screaming)
143
00:11:14,775 --> 00:11:15,774
(screaming)
144
00:11:15,776 --> 00:11:22,080
(screaming)
145
00:11:22,082 --> 00:11:26,484
(music)
146
00:11:26,486 --> 00:11:33,358
(music)
147
00:11:33,360 --> 00:11:37,162
He'll rise in rank only if another member dies
148
00:11:37,164 --> 00:11:39,097
or leaves the clan.
149
00:11:50,510 --> 00:11:55,380
Months later, he's settled in,
150
00:11:55,382 --> 00:11:59,117
but he still sometimes travels alone.
151
00:11:59,119 --> 00:12:01,453
Despite his canine looks,
152
00:12:01,455 --> 00:12:06,324
he's more closely related to a cat than a dog.
153
00:12:06,326 --> 00:12:11,062
And though he has a reputation as a scavenger, he's a hunter.
154
00:12:13,366 --> 00:12:16,367
He's Africa's second-largest carnivore,
155
00:12:16,369 --> 00:12:21,005
after his archrival, the lion.
156
00:12:21,007 --> 00:12:25,477
(lowing)
157
00:12:25,479 --> 00:12:32,083
(lowing)
158
00:12:32,085 --> 00:12:33,952
Their territories overlap...
159
00:12:37,557 --> 00:12:41,860
...and so do their prey...
160
00:12:41,862 --> 00:12:43,495
(snorts)
161
00:12:43,497 --> 00:12:45,497
...which can make the big savanna
162
00:12:45,499 --> 00:12:47,899
feel a little overcrowded...
163
00:12:51,171 --> 00:12:54,873
...especially if you're a wildebeest.
164
00:13:06,887 --> 00:13:10,455
A lioness has her eye on a pretty large prize.
165
00:13:14,795 --> 00:13:18,696
And a hyena without a clan is hoping to take advantage.
166
00:13:18,698 --> 00:13:23,768
(music)
167
00:13:23,770 --> 00:13:25,637
(snorts)
168
00:13:25,639 --> 00:13:31,810
(music)
169
00:13:31,812 --> 00:13:38,817
(music)
170
00:13:38,819 --> 00:13:45,824
(music)
171
00:13:45,826 --> 00:13:48,860
(music)
172
00:13:48,862 --> 00:13:53,998
(lowing)
173
00:13:54,000 --> 00:13:57,735
With the big cat doing the lion's share of the killing
174
00:13:57,737 --> 00:14:00,638
and the hyena doing his bit at the tail end,
175
00:14:00,640 --> 00:14:04,442
the wildebeest is history.
176
00:14:04,444 --> 00:14:07,612
Two enemy predators working together?
177
00:14:07,614 --> 00:14:11,683
The lioness disagrees.
178
00:14:11,685 --> 00:14:16,254
A lone lion makes a kill only about one out of six tries,
179
00:14:16,256 --> 00:14:19,123
so she's not in a sharing mood.
180
00:14:19,125 --> 00:14:23,828
(music)
181
00:14:23,830 --> 00:14:27,932
The hyena, who can devour bones, fur,
182
00:14:27,934 --> 00:14:30,168
everything but the horns,
183
00:14:30,170 --> 00:14:35,473
will wait his turn and still find enough to eat.
184
00:14:35,475 --> 00:14:39,210
Everybody wins, except the wildebeest.
185
00:14:40,981 --> 00:14:42,680
(laughing)
186
00:14:42,682 --> 00:14:44,515
This season, there's no shortage
187
00:14:44,517 --> 00:14:46,818
of wildebeest on the plains
188
00:14:46,820 --> 00:14:50,054
or big cats skilled enough to take them down...
189
00:14:50,056 --> 00:14:54,325
(music)
190
00:14:54,327 --> 00:14:57,595
...and one hyena who thinks stealing food from his rivals
191
00:14:57,597 --> 00:14:59,764
is the ticket to success.
192
00:14:59,766 --> 00:15:03,835
(music)
193
00:15:03,837 --> 00:15:09,507
(music)
194
00:15:09,509 --> 00:15:14,445
He's about to find out it isn't.
195
00:15:14,447 --> 00:15:18,149
(music)
196
00:15:18,151 --> 00:15:25,056
(music)
197
00:15:25,058 --> 00:15:30,762
Lions and hyenas are like rival gangs vying for turf.
198
00:15:30,764 --> 00:15:34,465
A single hyena isn't an immediate threat,
199
00:15:34,467 --> 00:15:36,100
but he's still the enemy.
200
00:15:39,439 --> 00:15:42,740
And one hyena is one too many.
201
00:15:42,742 --> 00:15:49,681
(music)
202
00:15:49,683 --> 00:15:50,848
(music)
203
00:15:50,850 --> 00:15:57,755
(music)
204
00:15:57,757 --> 00:15:59,824
The opportunistic hyena sees the lions
205
00:15:59,826 --> 00:16:02,060
as a convenient catering service.
206
00:16:05,365 --> 00:16:08,766
But he may be about to bite off more than he can chew.
207
00:16:08,768 --> 00:16:15,773
(music)
208
00:16:15,775 --> 00:16:22,714
(music)
209
00:16:22,716 --> 00:16:26,617
(music)
210
00:16:26,619 --> 00:16:28,186
(laughs)
211
00:16:31,257 --> 00:16:35,626
(music)
212
00:16:35,628 --> 00:16:39,697
(screaming)
213
00:16:39,699 --> 00:16:45,636
(screaming)
214
00:16:45,638 --> 00:16:52,610
(music)
215
00:16:52,612 --> 00:16:53,644
(music)
216
00:16:53,646 --> 00:16:59,817
(music)
217
00:16:59,819 --> 00:17:02,320
This gang of carnivores certainly shows
218
00:17:02,322 --> 00:17:05,423
who rules over this savanna.
219
00:17:05,425 --> 00:17:11,462
(music)
220
00:17:11,464 --> 00:17:17,468
(music)
221
00:17:17,470 --> 00:17:21,005
(squeaking)
222
00:17:21,007 --> 00:17:23,207
A much smaller killer gang has evolved
223
00:17:23,209 --> 00:17:28,513
to cash in on another abundant source of prey.
224
00:17:28,515 --> 00:17:31,616
Banded mongooses are top of the food chain
225
00:17:31,618 --> 00:17:34,285
but below the grass line.
226
00:17:34,287 --> 00:17:37,121
(squeaking)
227
00:17:37,123 --> 00:17:39,557
They live in large, close-knit troops,
228
00:17:39,559 --> 00:17:43,261
and like lions and hyenas, they usually stick together.
229
00:17:45,398 --> 00:17:47,131
But when it comes to hunting,
230
00:17:47,133 --> 00:17:51,035
their tactics couldn't be more different.
231
00:17:51,037 --> 00:17:55,073
At dinnertime, it's every mongoose for itself.
232
00:17:56,676 --> 00:17:58,543
Each animal raids the undergrowth
233
00:17:58,545 --> 00:18:01,379
for anything that crawls
234
00:18:01,381 --> 00:18:06,350
and hoards what it finds to keep for itself.
235
00:18:06,352 --> 00:18:08,453
So why do they stick together?
236
00:18:10,723 --> 00:18:12,757
At half the weight of a dachshund,
237
00:18:12,759 --> 00:18:15,893
mongooses are small predators with a big problem.
238
00:18:18,865 --> 00:18:21,399
They're also prey.
239
00:18:30,577 --> 00:18:31,742
Every predator larger than itself
240
00:18:31,744 --> 00:18:34,212
is a threat to the mongoose,
241
00:18:34,214 --> 00:18:39,317
especially to the bite-sized babies they hide in their dens.
242
00:18:39,319 --> 00:18:42,186
Hunting together means there's always a set of eyes
243
00:18:42,188 --> 00:18:43,788
scouting the terrain.
244
00:18:46,759 --> 00:18:49,127
And they're always ready to retreat
245
00:18:49,129 --> 00:18:51,129
at the first sign of danger.
246
00:18:51,131 --> 00:18:57,135
(music)
247
00:18:57,137 --> 00:19:03,608
(music)
248
00:19:03,610 --> 00:19:08,779
(squeaking)
249
00:19:10,316 --> 00:19:12,116
But not everyone makes it.
250
00:19:12,118 --> 00:19:14,919
(squeaking)
251
00:19:14,921 --> 00:19:17,088
Ever present danger has groomed mongooses
252
00:19:17,090 --> 00:19:21,759
into nervous, flighty creatures,
253
00:19:21,761 --> 00:19:23,561
yet there are some deadly predators
254
00:19:23,563 --> 00:19:25,730
that bring out a side to this troop
255
00:19:25,732 --> 00:19:28,332
that borders on suicidal.
256
00:19:32,372 --> 00:19:35,039
Snakes are specialists at invading the narrow dens
257
00:19:35,041 --> 00:19:37,542
where mongooses hide their infants.
258
00:19:40,747 --> 00:19:44,749
When scouts spot one, they put out a call to arms.
259
00:19:47,453 --> 00:19:50,454
The entire troop races to meet the enemy.
260
00:19:50,456 --> 00:19:55,660
(music)
261
00:19:55,662 --> 00:20:00,665
This Mozambican spitting cobra can kill a human.
262
00:20:00,667 --> 00:20:05,536
Its bite packs a potent cytotoxin that dissolves flesh.
263
00:20:05,538 --> 00:20:10,107
(squeaking)
264
00:20:10,109 --> 00:20:11,709
Yet this is one predator
265
00:20:11,711 --> 00:20:14,245
that these little mammals will attack.
266
00:20:17,350 --> 00:20:20,251
The snake is a deadly threat to their young,
267
00:20:20,253 --> 00:20:21,819
but if they can defeat it,
268
00:20:21,821 --> 00:20:26,591
a dead reptile doubles as a protein-rich meal.
269
00:20:26,593 --> 00:20:28,626
Eons of conflict with snakes
270
00:20:28,628 --> 00:20:33,431
have armed the mongoose for this moment.
271
00:20:33,433 --> 00:20:37,902
They depend on quick reflexes, biting, and cracking the skull.
272
00:20:40,673 --> 00:20:44,408
And if all else fails, they have another trick.
273
00:20:44,410 --> 00:20:51,315
(squeaking)
274
00:20:51,317 --> 00:20:56,354
Mongooses are virtually immune to the cobra's venom.
275
00:20:56,356 --> 00:21:01,859
Now the mongooses need family teamwork to succeed.
276
00:21:01,861 --> 00:21:03,861
With so many moving targets,
277
00:21:03,863 --> 00:21:07,298
the cobra can't choose who to attack.
278
00:21:07,300 --> 00:21:10,401
Biting isn't the snake's only weapon.
279
00:21:14,474 --> 00:21:16,774
It can shoot a blinding jet of venom
280
00:21:16,776 --> 00:21:19,176
straight for its enemy's eyes.
281
00:21:22,649 --> 00:21:24,782
But the mongoose's lightning quick reflexes
282
00:21:24,784 --> 00:21:27,285
keep them out of the line of fire.
283
00:21:27,287 --> 00:21:30,521
(squeaking)
284
00:21:30,523 --> 00:21:32,290
They keep the pressure on,
285
00:21:32,292 --> 00:21:36,894
until the cobra tries to escape,
286
00:21:36,896 --> 00:21:39,930
and then attack when it's on the retreat.
287
00:21:39,932 --> 00:21:46,770
(music)
288
00:21:46,772 --> 00:21:52,743
(music)
289
00:21:52,745 --> 00:21:56,781
(music)
290
00:21:56,783 --> 00:22:01,519
(music)
291
00:22:01,521 --> 00:22:03,120
With needle-like teeth,
292
00:22:03,122 --> 00:22:05,956
they tear the snake apart and devour it.
293
00:22:08,461 --> 00:22:12,263
(squeaking)
294
00:22:12,265 --> 00:22:14,665
Mongooses and their relatives
295
00:22:14,667 --> 00:22:19,203
are among the top natural enemies of African snakes.
296
00:22:22,975 --> 00:22:26,143
While the mongoose posse seeks out its dinner,
297
00:22:26,145 --> 00:22:28,412
a killer gang of Nile crocodiles
298
00:22:28,414 --> 00:22:31,415
waits for their dinner to come to them.
299
00:22:35,088 --> 00:22:38,622
Tipping the scales at more than 500 pounds,
300
00:22:38,624 --> 00:22:41,625
they can eat half their own body weight in one sitting.
301
00:22:44,564 --> 00:22:47,898
And when there's this many hungry crocs,
302
00:22:47,900 --> 00:22:50,701
it's a good thing dinner is on its way.
303
00:22:55,575 --> 00:22:57,108
Over a million wildebeest
304
00:22:57,110 --> 00:22:59,944
migrate about a thousand miles a year.
305
00:23:03,516 --> 00:23:05,449
They're joined by zebras...
306
00:23:08,588 --> 00:23:10,554
...who graze the coarser blades of grass
307
00:23:10,556 --> 00:23:13,124
the wildebeests don't touch.
308
00:23:13,126 --> 00:23:18,162
(zebra braying)
309
00:23:18,164 --> 00:23:21,365
And as they chew their way across the Serengeti,
310
00:23:21,367 --> 00:23:25,336
they'll need something to wash it down.
311
00:23:25,338 --> 00:23:27,071
They'll soon learn,
312
00:23:27,073 --> 00:23:30,574
there's always a price to pay for a free drink.
313
00:23:36,449 --> 00:23:39,049
(lowing)
314
00:23:39,051 --> 00:23:41,519
Zebras need to drink daily.
315
00:23:45,591 --> 00:23:48,426
But sticking their nose into a dangerous river
316
00:23:48,428 --> 00:23:51,762
is just the beginning.
317
00:23:51,764 --> 00:23:55,866
They've still got to get across it for greener pastures.
318
00:24:07,447 --> 00:24:09,246
For the zebras,
319
00:24:09,248 --> 00:24:13,384
the instinct to cross the river is too powerful to ignore.
320
00:24:15,354 --> 00:24:19,323
And the croc's instinct to eat is powerful, too.
321
00:24:24,063 --> 00:24:27,031
The ability to run fast and kick hard
322
00:24:27,033 --> 00:24:30,000
is useless in the river.
323
00:24:30,002 --> 00:24:34,772
(music)
324
00:24:34,774 --> 00:24:39,043
Here, giant primitive reptiles call the shots.
325
00:24:49,789 --> 00:24:52,423
But the zebras press forward.
326
00:24:52,425 --> 00:24:56,760
(braying)
327
00:24:56,762 --> 00:25:02,766
(braying)
328
00:25:02,768 --> 00:25:04,435
(music)
329
00:25:04,437 --> 00:25:11,375
(music)
330
00:25:11,377 --> 00:25:14,545
Even though multiple predators are breathing down their necks,
331
00:25:14,547 --> 00:25:17,314
the stream of zebras never stops.
332
00:25:17,316 --> 00:25:23,787
(music)
333
00:25:23,789 --> 00:25:30,794
(music)
334
00:25:30,796 --> 00:25:36,200
(music)
335
00:25:36,202 --> 00:25:39,369
The terrified herd tramples over a croc,
336
00:25:39,371 --> 00:25:42,373
who fumbles and loses its grip on a victim.
337
00:25:48,414 --> 00:25:54,785
(braying)
338
00:25:54,787 --> 00:25:59,390
(music)
339
00:25:59,392 --> 00:26:05,229
The predator heads to deeper water to gain an advantage.
340
00:26:05,231 --> 00:26:08,065
He spots a struggling foal.
341
00:26:08,067 --> 00:26:13,070
(music)
342
00:26:13,072 --> 00:26:19,910
(music)
343
00:26:19,912 --> 00:26:22,279
But the current carries it out of reach...
344
00:26:26,185 --> 00:26:29,286
...giving his desperate mother time to block him.
345
00:26:29,288 --> 00:26:33,657
(music)
346
00:26:33,659 --> 00:26:37,461
While the mare distracts the croc,
347
00:26:37,463 --> 00:26:39,964
the foal struggles to make shore.
348
00:26:39,966 --> 00:26:41,999
(music)
349
00:26:42,001 --> 00:26:48,906
(music)
350
00:26:48,908 --> 00:26:52,343
Mother is safe,
351
00:26:52,345 --> 00:26:54,178
but her instinct to rejoin the herd
352
00:26:54,180 --> 00:26:58,382
overpowers her need to save her foal.
353
00:26:58,384 --> 00:27:00,651
He'll have to catch up.
354
00:27:00,653 --> 00:27:05,823
(music)
355
00:27:05,825 --> 00:27:12,563
(music)
356
00:27:12,565 --> 00:27:17,901
(braying)
357
00:27:17,903 --> 00:27:22,006
The croc doesn't give up and seeks out an easier target.
358
00:27:24,910 --> 00:27:27,378
This zebra's in over his head.
359
00:27:27,380 --> 00:27:33,784
(music)
360
00:27:33,786 --> 00:27:40,791
(music)
361
00:27:40,793 --> 00:27:46,497
(music)
362
00:27:46,499 --> 00:27:47,631
(brays)
363
00:27:47,633 --> 00:27:54,538
(music)
364
00:27:54,540 --> 00:28:01,578
(music)
365
00:28:01,580 --> 00:28:08,285
(music)
366
00:28:08,287 --> 00:28:10,921
The crocodile drowns its prey.
367
00:28:15,961 --> 00:28:17,761
A valve in the big reptile's throat
368
00:28:17,763 --> 00:28:21,899
lets it keep its death grip without swallowing water.
369
00:28:21,901 --> 00:28:23,934
(music)
370
00:28:23,936 --> 00:28:30,808
(music)
371
00:28:30,810 --> 00:28:33,811
While the croc is busy making its kill,
372
00:28:33,813 --> 00:28:36,914
the rest of the zebras can cross safely.
373
00:28:39,852 --> 00:28:41,585
What the croc can't finish,
374
00:28:41,587 --> 00:28:45,322
he'll wedge under rocks in the cold water for later.
375
00:28:48,094 --> 00:28:51,228
But there won't be leftovers today.
376
00:28:51,230 --> 00:28:55,699
For a croc, this is a dinner roll.
377
00:28:55,701 --> 00:28:59,136
The technique helps him bite off chunks of meat.
378
00:28:59,138 --> 00:29:02,506
The toothy beasts don't waste time chewing.
379
00:29:02,508 --> 00:29:09,446
(music)
380
00:29:09,448 --> 00:29:10,481
(music)
381
00:29:10,483 --> 00:29:17,421
(music)
382
00:29:17,423 --> 00:29:20,824
Meanwhile, the lucky ones keep going,
383
00:29:20,826 --> 00:29:23,160
a constant stream of grass-eaters
384
00:29:23,162 --> 00:29:26,163
following the grass.
385
00:29:30,936 --> 00:29:35,072
In the dusty bush of Tuli, Botswana,
386
00:29:35,074 --> 00:29:36,673
another cast of prey animals
387
00:29:36,675 --> 00:29:39,910
has found their own unique way to stay alive.
388
00:29:42,782 --> 00:29:46,150
Antelope trade strength for speed.
389
00:29:49,789 --> 00:29:52,656
Their spring-loaded legs allow rapid acceleration,
390
00:29:52,658 --> 00:29:56,393
up to twice the speed of the fastest Olympian.
391
00:29:56,395 --> 00:30:01,031
Here, only the fastest and fittest survive
392
00:30:01,033 --> 00:30:04,635
because this is wild dog country.
393
00:30:16,549 --> 00:30:19,983
A quarter the size of lions but double their speed,
394
00:30:19,985 --> 00:30:24,254
wild dogs kill fast, brutally, and often.
395
00:30:28,594 --> 00:30:31,795
One dog weighs little more than a German shepherd,
396
00:30:31,797 --> 00:30:33,897
but they're armed with the most powerful jaws
397
00:30:33,899 --> 00:30:37,668
for their size of all mammals.
398
00:30:37,670 --> 00:30:39,436
Working together,
399
00:30:39,438 --> 00:30:45,209
they're the most efficient killers on the continent.
400
00:30:45,211 --> 00:30:48,979
What they lack in size, they make up for in numbers.
401
00:30:52,384 --> 00:30:57,421
Packs of over 100 wild dogs once roamed Africa.
402
00:30:57,423 --> 00:31:01,091
Today they teeter on the brink of extinction,
403
00:31:01,093 --> 00:31:05,729
yet in places like Tuli, up to 50 dogs may run together.
404
00:31:08,400 --> 00:31:13,036
Pack mates are obsessively affectionate.
405
00:31:13,038 --> 00:31:15,272
Constant contact and vocalizations
406
00:31:15,274 --> 00:31:17,708
cement the tight bonds within the group.
407
00:31:20,379 --> 00:31:24,114
All of them submit to the authority of two top dogs,
408
00:31:24,116 --> 00:31:26,917
an alpha male and female.
409
00:31:29,088 --> 00:31:33,724
They determine when, where, and what the pack hunts.
410
00:31:35,761 --> 00:31:37,661
Wild dogs may roam a home range
411
00:31:37,663 --> 00:31:40,097
twice the size of New York City
412
00:31:40,099 --> 00:31:44,201
and cover over 30 miles a day in search of prey.
413
00:31:44,203 --> 00:31:45,869
Between hunting missions,
414
00:31:45,871 --> 00:31:50,040
the dogs play-fight, keeping them fit and agile.
415
00:31:50,042 --> 00:31:53,210
(squealing)
416
00:31:53,212 --> 00:31:56,346
Their home base is the den where they hide their cubs,
417
00:31:56,348 --> 00:31:58,849
but they're always ready for action.
418
00:31:58,851 --> 00:32:02,719
(squealing)
419
00:32:05,357 --> 00:32:07,991
A herd of eland passes dangerously close
420
00:32:07,993 --> 00:32:09,693
to the hidden barracks.
421
00:32:09,695 --> 00:32:15,499
(music)
422
00:32:15,501 --> 00:32:17,834
It's time to move out.
423
00:32:21,273 --> 00:32:24,374
These giants are the slowest of all antelopes,
424
00:32:24,376 --> 00:32:27,077
but that doesn't make them easy prey.
425
00:32:27,079 --> 00:32:29,713
They're also the biggest antelope--
426
00:32:29,715 --> 00:32:32,716
ten times the size of a wild dog--
427
00:32:32,718 --> 00:32:36,720
and they can kill with their huge twisted horns.
428
00:32:36,722 --> 00:32:41,224
It would be suicide to tackle the herd head-on.
429
00:32:41,226 --> 00:32:43,860
Like a pack of lions with Cape buffalo,
430
00:32:43,862 --> 00:32:47,197
the dogs need to weaken their prey first,
431
00:32:47,199 --> 00:32:50,500
but they won't do it with pain.
432
00:32:50,502 --> 00:32:55,505
This will be a battle of endurance.
433
00:32:55,507 --> 00:33:01,878
The pack splits into two groups--flankers and chasers.
434
00:33:01,880 --> 00:33:04,748
Flankers move ahead to block side escape routes,
435
00:33:04,750 --> 00:33:07,951
while the chasers push the herd from behind.
436
00:33:07,953 --> 00:33:12,889
(music)
437
00:33:12,891 --> 00:33:14,825
There's no stalking.
438
00:33:14,827 --> 00:33:18,195
They want the herd to see them and bolt.
439
00:33:18,197 --> 00:33:21,999
(music)
440
00:33:22,001 --> 00:33:28,305
(music)
441
00:33:28,307 --> 00:33:29,873
The flankers channel the fleeing antelope
442
00:33:29,875 --> 00:33:31,508
through the bush,
443
00:33:31,510 --> 00:33:34,244
as the chasers increase the pace,
444
00:33:34,246 --> 00:33:37,981
until the prey can run no more.
445
00:33:37,983 --> 00:33:39,016
(music)
446
00:33:39,018 --> 00:33:45,989
(music)
447
00:33:45,991 --> 00:33:50,127
Exhaustion drives the eland to stop and face their enemies.
448
00:33:53,232 --> 00:33:56,066
The pack splits up and isolates victims.
449
00:33:56,068 --> 00:34:01,171
(music)
450
00:34:01,173 --> 00:34:07,310
(music)
451
00:34:07,312 --> 00:34:10,180
Three eland go down.
452
00:34:13,819 --> 00:34:17,020
Each dog latches on with jaws like a bear trap
453
00:34:17,022 --> 00:34:19,489
and jerks hard to rip open the skin.
454
00:34:19,491 --> 00:34:22,492
(squealing)
455
00:34:22,494 --> 00:34:24,061
Though it looks brutal,
456
00:34:24,063 --> 00:34:28,298
shock numbs the pain, and death is swift.
457
00:34:28,300 --> 00:34:31,301
(squealing)
458
00:34:31,303 --> 00:34:33,003
In a matter of minutes,
459
00:34:33,005 --> 00:34:37,107
there's nothing left but bones and a bloodstain.
460
00:34:42,781 --> 00:34:47,417
Stomachs full, they head home, but this meal isn't over.
461
00:34:49,955 --> 00:34:55,325
Each dog's gut literally acts as a doggie bag.
462
00:34:55,327 --> 00:34:58,361
At the den, the hunters regurgitate meat
463
00:34:58,363 --> 00:35:02,666
and share it among the pups and the adults.
464
00:35:02,668 --> 00:35:05,635
They feed more than 30 mouths off a single hunt,
465
00:35:05,637 --> 00:35:09,940
and tomorrow, they'll do it all over again.
466
00:35:09,942 --> 00:35:14,277
Feeding this growing predator army is a full-time job.
467
00:35:14,279 --> 00:35:18,315
(music)
468
00:35:18,317 --> 00:35:23,687
(music)
469
00:35:23,689 --> 00:35:25,388
South Africa's Kruger National Park
470
00:35:25,390 --> 00:35:28,258
is an area renowned for its predators.
471
00:35:28,260 --> 00:35:31,661
Ironically, one of the most dangerous creatures of all
472
00:35:31,663 --> 00:35:34,698
isn't a killer carnivore.
473
00:35:34,700 --> 00:35:38,401
It's a deadly herbivore--
474
00:35:38,403 --> 00:35:40,036
the hippopotamus.
475
00:35:48,914 --> 00:35:52,415
Only the Nile crocodile rivals the hippo's human death toll.
476
00:35:54,953 --> 00:35:56,520
The hyper-aggressive grazers
477
00:35:56,522 --> 00:35:59,756
come armed with canines the length of a forearm
478
00:35:59,758 --> 00:36:03,727
and jaws that can crush a man to death.
479
00:36:03,729 --> 00:36:08,498
Their deadly trait is a hair-trigger temper,
480
00:36:08,500 --> 00:36:10,167
so hippos will charge and attack
481
00:36:10,169 --> 00:36:12,669
any threat that gets too close.
482
00:36:12,671 --> 00:36:18,942
(music)
483
00:36:18,944 --> 00:36:22,445
They feed on grass, but Kruger's blazing sun
484
00:36:22,447 --> 00:36:25,448
scorches their sensitive, hairless skin.
485
00:36:29,188 --> 00:36:31,521
Hippos must spend daylight hours in the water
486
00:36:31,523 --> 00:36:33,957
to protect themselves from sunstroke.
487
00:36:37,429 --> 00:36:41,865
But in the dry winter, water is a precious resource.
488
00:36:44,937 --> 00:36:48,738
Dominant male hippos guard it like gold.
489
00:36:48,740 --> 00:36:51,675
They'll share their stretch of river with harems of females
490
00:36:51,677 --> 00:36:53,944
to secure mating rights.
491
00:36:56,915 --> 00:37:01,218
But they'll fight off any male that invades their space.
492
00:37:01,220 --> 00:37:07,157
(music)
493
00:37:07,159 --> 00:37:08,625
This bull wants in
494
00:37:08,627 --> 00:37:11,228
on the dominant male's stretch of river.
495
00:37:11,230 --> 00:37:17,234
(music)
496
00:37:17,236 --> 00:37:22,772
(music)
497
00:37:22,774 --> 00:37:26,209
They wield their massive canines like daggers
498
00:37:26,211 --> 00:37:28,612
to gore each other's gums.
499
00:37:28,614 --> 00:37:33,650
(music)
500
00:37:33,652 --> 00:37:40,523
(music)
501
00:37:40,525 --> 00:37:43,526
The duel stops only when there's a clear winner.
502
00:37:46,231 --> 00:37:49,833
The loser backs off, sheaths his weapons,
503
00:37:49,835 --> 00:37:52,235
and blubbers his submission.
504
00:37:52,237 --> 00:37:53,770
He's lucky.
505
00:37:53,772 --> 00:37:56,740
Battles like this can rage to the death
506
00:37:56,742 --> 00:37:59,843
or leave survivors scarred for life.
507
00:38:06,918 --> 00:38:08,752
(music)
508
00:38:08,754 --> 00:38:15,659
(music)
509
00:38:15,661 --> 00:38:19,963
When the brutal sun retreats, the hippos finally get to feed.
510
00:38:23,168 --> 00:38:24,834
Under the cover of darkness,
511
00:38:24,836 --> 00:38:27,504
the three-ton beasts leave the water
512
00:38:27,506 --> 00:38:30,173
and head out into the grasslands to graze.
513
00:38:37,416 --> 00:38:39,516
They have little to fear.
514
00:38:39,518 --> 00:38:41,885
They're more dangerous than most of the predators
515
00:38:41,887 --> 00:38:44,287
that trawl this bush--
516
00:38:44,289 --> 00:38:47,590
most, but not all.
517
00:38:47,592 --> 00:38:50,994
There's a pack of killers that will risk everything
518
00:38:50,996 --> 00:38:55,398
to feast on these mountains of meat--
519
00:38:55,400 --> 00:38:59,069
one of Africa's most powerful terrestrial predators--
520
00:39:02,741 --> 00:39:04,207
lions.
521
00:39:08,980 --> 00:39:13,550
A pride of 16 has this bull surrounded.
522
00:39:13,552 --> 00:39:20,523
(music)
523
00:39:20,525 --> 00:39:23,093
They mob him with jaws and claws.
524
00:39:26,131 --> 00:39:28,965
The hippo can crush a skull with a bite.
525
00:39:31,470 --> 00:39:35,505
He's as likely to kill a lion as the lions are to kill him.
526
00:39:35,507 --> 00:39:41,711
(music)
527
00:39:41,713 --> 00:39:48,718
(music)
528
00:39:48,720 --> 00:39:53,757
(music)
529
00:39:53,759 --> 00:39:59,629
(music)
530
00:39:59,631 --> 00:40:02,432
The hippo wins this fight.
531
00:40:05,804 --> 00:40:08,271
Lions have to live with failure.
532
00:40:08,273 --> 00:40:11,941
Only three out of ten hunts result in a kill.
533
00:40:11,943 --> 00:40:13,777
That's the cost of taking on
534
00:40:13,779 --> 00:40:17,647
one of the largest and most dangerous species in Africa.
535
00:40:21,119 --> 00:40:22,886
But daylight brings new opportunities
536
00:40:22,888 --> 00:40:25,755
for the most ambitious of predators.
537
00:40:25,757 --> 00:40:27,557
Prides up to 20 strong
538
00:40:27,559 --> 00:40:31,594
can match Africa's largest herbivores pound for pound.
539
00:40:36,001 --> 00:40:39,302
In addition, each pride has a secret weapon
540
00:40:39,304 --> 00:40:41,838
that ups the odds of success--
541
00:40:44,976 --> 00:40:46,075
males.
542
00:40:49,448 --> 00:40:52,382
Reaching over 440 pounds,
543
00:40:52,384 --> 00:40:55,285
male lions weigh as much as a motorcycle
544
00:40:55,287 --> 00:40:58,755
and can body-slam prey like a head-on collision.
545
00:40:58,757 --> 00:41:04,127
(music)
546
00:41:04,129 --> 00:41:07,163
(roaring)
547
00:41:07,165 --> 00:41:10,133
(roaring)
548
00:41:13,138 --> 00:41:18,408
A male's power could have sealed the hippo's fate,
549
00:41:18,410 --> 00:41:21,177
but their help is never guaranteed.
550
00:41:23,915 --> 00:41:25,682
Despite their strength,
551
00:41:25,684 --> 00:41:28,284
male lions leave most of the hard work of hunting
552
00:41:28,286 --> 00:41:30,019
to the females.
553
00:41:35,093 --> 00:41:39,496
The lionesses take feeding the pride into their own hands.
554
00:41:42,300 --> 00:41:48,238
They set their sights on another deadly giant--
555
00:41:48,240 --> 00:41:51,007
a giraffe.
556
00:41:51,009 --> 00:41:54,277
This towering browser has an elegant gait,
557
00:41:54,279 --> 00:41:57,614
but its powerful kick can kill a lion.
558
00:42:00,519 --> 00:42:04,554
The pride must carefully corner their victim.
559
00:42:04,556 --> 00:42:11,528
(music)
560
00:42:11,530 --> 00:42:17,700
(music)
561
00:42:17,702 --> 00:42:24,641
(music)
562
00:42:24,643 --> 00:42:31,614
(music)
563
00:42:31,616 --> 00:42:38,555
(music)
564
00:42:38,557 --> 00:42:45,528
(music)
565
00:42:45,530 --> 00:42:51,534
(music)
566
00:42:51,536 --> 00:42:57,974
(music)
567
00:42:57,976 --> 00:42:59,642
Surrounded on all sides,
568
00:42:59,644 --> 00:43:02,679
the giraffe has too many targets.
569
00:43:02,681 --> 00:43:05,582
It can't fend all the lions off at once.
570
00:43:05,584 --> 00:43:11,721
(music)
571
00:43:11,723 --> 00:43:17,760
(music)
572
00:43:17,762 --> 00:43:24,100
(music)
573
00:43:24,102 --> 00:43:27,003
Every kick could be a deathblow,
574
00:43:27,005 --> 00:43:28,638
but the lions risk it.
575
00:43:28,640 --> 00:43:34,611
(music)
576
00:43:34,613 --> 00:43:38,214
They need to pull the giraffe off-balance to get it down,
577
00:43:38,216 --> 00:43:42,919
but they don't have the weight.
578
00:43:42,921 --> 00:43:47,056
When all hope of a kill seems lost,
579
00:43:47,058 --> 00:43:50,893
the male lion attacks like a wrecking ball.
580
00:43:50,895 --> 00:43:57,667
(music)
581
00:43:57,669 --> 00:44:03,973
(music)
582
00:44:03,975 --> 00:44:09,746
His weight topples the giraffe at last.
583
00:44:09,748 --> 00:44:15,151
A kill this size is worth risking lives for.
584
00:44:15,153 --> 00:44:21,591
It will feed a pride of some of Africa's deadliest for days.
585
00:44:21,593 --> 00:44:27,163
(music)
