This is...Deadly 360.

0:00:020:00:05

The show that pits three of the world's deadliest predators

0:00:050:00:09

against their prey.

0:00:090:00:10

Examining their hunting strategies and escape tactics...

0:00:100:00:14

from every angle.

0:00:140:00:17

By delving beneath the fur and the feathers

0:00:170:00:20

we find out why a hunt succeeds...

0:00:200:00:23

and why they sometimes fail.

0:00:230:00:26

One thing's certain -

0:00:260:00:27

prey animals are anything BUT sitting ducks.

0:00:270:00:31

Their defensive strategies keep them alive.

0:00:310:00:34

And push predators to the limits.

0:00:360:00:39

Prepare for Deadly 360.

0:00:400:00:42

This is Deadly 360 mission control,

0:00:440:00:48

where all of today's action and analysis takes place.

0:00:480:00:51

From here we have access to some of the most enthralling hunts

0:00:510:00:56

that have ever been caught on camera.

0:00:560:00:59

I've recreated three of the most exciting

0:00:590:01:01

and analysed them from a variety of different angles and perspectives

0:01:010:01:06

in true 360-degree style.

0:01:060:01:08

The predators have to find and catch food

0:01:080:01:10

or they just won't make it.

0:01:100:01:12

In the wild, managing to survive is the greatest challenge of all.

0:01:120:01:17

I present to you...the big cats.

0:01:170:01:20

In today's line-up, we look at the world's fastest land animal,

0:01:200:01:25

the cheetah.

0:01:250:01:27

A speed merchant who lives life at a rocket's pace.

0:01:270:01:30

We also meet a group of lionesses - masters of group hunting

0:01:300:01:35

who are not afraid to tackle prey twice their size.

0:01:350:01:39

And in the forests of India,

0:01:390:01:41

the magnificent tiger who uses stealth to track down prey.

0:01:410:01:45

Three big cats, three very different hunting strategies, all deadly.

0:01:450:01:50

They look invincible

0:01:500:01:52

but there's a continual arms race going on in nature,

0:01:520:01:55

which ensures that prey animals are always evolving spectacular ways

0:01:550:01:59

of taking care of themselves.

0:01:590:02:01

Today's line-up of defenders

0:02:010:02:04

includes the gazelle -

0:02:040:02:05

an agile antelope with an incredible turn of speed.

0:02:050:02:08

And the zebra, a true master of confusion with moves to match.

0:02:080:02:14

And we analyse the deer's many moves for evasion and escape.

0:02:140:02:18

Three different prey, three different escape strategies

0:02:190:02:23

to deny the most persistent of predators.

0:02:230:02:26

I've introduced you to all of our contenders,

0:02:260:02:29

now it's time to meet our first deadly duo going head-to-head.

0:02:290:02:33

Our first competitor is a cat that is a true athlete

0:02:360:02:39

and complete speed freak. It's the cheetah.

0:02:390:02:43

And up against it, is this...

0:02:430:02:45

..the Thomson's gazelle.

0:02:460:02:48

But which animal has the edge in the race for life?

0:02:500:02:53

It's time to go Deadly 360.

0:02:530:02:56

We join the action just before the critical moment of impact.

0:02:590:03:03

This is the cheetah at full speed, hurtling across the land

0:03:030:03:07

at nearly 70 miles an hour.

0:03:070:03:09

And the gazelle is twisting and turning at speed,

0:03:090:03:12

certainly no easy meal.

0:03:120:03:14

But up against this lightning hunter,

0:03:140:03:17

it looks like the gazelle's met its match.

0:03:170:03:19

Even in a hunt like this, there are still lots of factors in play.

0:03:190:03:23

To find out why a predator might succeed or fail,

0:03:230:03:26

we need to wind back the action and build-up the entire hunt,

0:03:260:03:30

right from the beginning.

0:03:300:03:32

This hunt takes place in East Africa.

0:03:340:03:36

In the savannah of the Masai Mara.

0:03:390:03:41

This is one of the world's great wildlife hot spots

0:03:410:03:45

and it's the typical habitat for the cheetah.

0:03:450:03:48

Open plains, shrublands, but also very high temperatures.

0:03:480:03:52

These open grasslands, though,

0:03:520:03:54

allow the cheetah to get a fantastic panoramic view of their prey

0:03:540:03:58

before selecting a target.

0:03:580:04:00

And where you find wide-open grasslands

0:04:000:04:03

you find browsers and grazers,

0:04:030:04:05

including small antelope called gazelles.

0:04:050:04:08

Grazing in large herds,

0:04:080:04:09

they flock to the grassy plains where the landscape's open,

0:04:090:04:13

allowing them to feed on the short grass.

0:04:130:04:16

We've set the scene,

0:04:160:04:17

but how do these animals operate in this environment

0:04:170:04:20

and what attributes do they have

0:04:200:04:22

that tip the balance in their favour?

0:04:220:04:25

First up, the cheetah has binocular vision,

0:04:270:04:30

perfect for picking out gazelles up to three miles away.

0:04:300:04:35

Next, it's the cheetah's famous acceleration and its speed -

0:04:350:04:39

0 - 65 miles an hour in three seconds!

0:04:390:04:42

And finally, its claws - curved, sharp, lethal.

0:04:430:04:48

With all that to help it hunt, you'd think that our predator

0:04:480:04:52

would have no trouble making a kill.

0:04:520:04:54

But our prey also has some pretty nifty means of defence.

0:04:540:04:58

Gazelles can't match the speed of the cheetah

0:04:580:05:01

but they can outrun them over long distances

0:05:010:05:04

and that's down to their amazing stamina.

0:05:040:05:07

They're also excellent escape artists

0:05:070:05:10

with the ability to leap four and a half metres in a single bound

0:05:100:05:14

and make sharp turns to outmanoeuvre the cheetah.

0:05:140:05:17

So it's not going to be easy for any predator to pick off that prey.

0:05:200:05:24

That's the background - let's get the hunt underway.

0:05:240:05:28

The cheetah's spotted the herd of gazelles

0:05:280:05:31

but there's a group of 60-plus individuals

0:05:310:05:34

so first, it needs to select a target

0:05:340:05:36

and the secret to that is in its eyes.

0:05:360:05:39

The cheetah relies almost entirely on its vision

0:05:390:05:43

to track down its prey.

0:05:430:05:44

The fovea, the area at the back of the eye which gives focus,

0:05:440:05:48

is much broader than our own.

0:05:480:05:50

It gives them a panoramic view which is twice as wide as we can see.

0:05:500:05:56

They also have an amazing amount of sharp focus,

0:05:560:05:59

and can see their prey as much as three miles away.

0:05:590:06:03

In preparation for the chase, the cheetah absorbs oxygen

0:06:030:06:06

into her body,

0:06:060:06:08

through her large nostrils.

0:06:080:06:09

They can increase their breathing rate

0:06:090:06:12

up to 150 breaths per minute.

0:06:120:06:14

That's more than double that of a professional athlete.

0:06:140:06:17

OK, let's check out the start of the hunt.

0:06:170:06:20

This acceleration is extraordinary.

0:06:200:06:23

Cheetahs have been clocked going from a standing start

0:06:230:06:26

to 64 miles an hour in three seconds.

0:06:260:06:28

Look at this, it's spending as much as half of its time

0:06:280:06:32

with all four feet off the ground.

0:06:320:06:34

It's pretty much flying!

0:06:340:06:36

This is a perfect opportunity to take a look at how it does it.

0:06:360:06:40

The cheetah is much lighter for its size than any other cat.

0:06:400:06:46

The reason for that is that the bones are longer, slimmer,

0:06:460:06:50

and much more lightweight.

0:06:500:06:51

The head's very small,

0:06:510:06:53

it offers the absolute minimum of wind resistance

0:06:530:06:56

and streamlines the animal as it drives forward.

0:06:560:06:59

Now let's look at its gait.

0:06:590:07:01

It's proceeding in a series of leaps,

0:07:010:07:04

almost extending its body into a horizontal shape.

0:07:040:07:07

The way it does that is by having incredibly flexible joints,

0:07:070:07:11

here at the hips and here at the shoulders.

0:07:110:07:14

As it runs, the spine flexes almost like a bow,

0:07:140:07:18

storing up elastic energy which retracts the feet back

0:07:180:07:21

at incredible speeds,

0:07:210:07:23

driving the animal forwards.

0:07:230:07:25

Let's see all of this in action.

0:07:250:07:27

Back to the hunt, and the cheetah's at full stretch.

0:07:310:07:34

Her temperature's rising to a staggering 40 degrees centigrade.

0:07:340:07:38

If she doesn't make the kill in 300 metres or so,

0:07:380:07:41

she'll overheat and that could be fatal.

0:07:410:07:43

Every extra second that the hunt lasts works in the gazelle's favour.

0:07:430:07:48

It's dodging from side to side, zigzagging, which really helps it

0:07:480:07:52

cos the cheetah goes in a straight line

0:07:520:07:54

and this movement will put it off its stride.

0:07:540:07:57

The longer it lasts

0:07:570:07:58

the more the gazelle's endurance comes into play

0:07:580:08:01

and that's all about its heart and lungs.

0:08:010:08:04

Let's take a closer look.

0:08:040:08:06

OK, this is our gazelle.

0:08:080:08:11

The windpipe is very large.

0:08:110:08:13

This means that it can suck in much more oxygen into its body

0:08:130:08:17

as it's running.

0:08:170:08:18

That oxygen is than transferred to the blood

0:08:180:08:21

and then powered around the body

0:08:210:08:23

using this, its heart.

0:08:230:08:25

It's about double the size of other animals

0:08:250:08:28

around about as big as this gazelle is.

0:08:280:08:31

That's the engine that's going to keep this animal moving

0:08:310:08:35

and that's the important thing.

0:08:350:08:37

So, certainly not helpless.

0:08:370:08:40

Let's return to the action.

0:08:400:08:43

With time now running out, the only way for her to succeed

0:08:460:08:50

is to trip the gazelle,

0:08:500:08:52

but to do this, she's got to get very close.

0:08:520:08:55

This is really the crux point of the hunt.

0:08:580:09:00

If she's miscalculated, she could easily receive

0:09:000:09:03

a kick to the head, which could even prove fatal.

0:09:030:09:06

It's the crucial moment.

0:09:060:09:08

As the cheetah's in its final stride, she takes a swipe and...

0:09:080:09:13

the gazelle's down, she's done it!

0:09:130:09:15

But it's actually even more impressive than that.

0:09:150:09:18

If we just rewind...and then watch it back in slow motion,

0:09:180:09:23

it looks like the gazelle's legs have been taken out from under it

0:09:230:09:27

but if we zoom in, you can see, the cheetah's sharp, hooked dew claw

0:09:270:09:31

has actually slashed right into the tendons of the gazelle.

0:09:310:09:35

It's left it with a really serious injury.

0:09:350:09:38

The cheetah can now head in

0:09:380:09:40

and with a bite to the throat, suffocate the animal.

0:09:400:09:43

That is a perfect and successful hunt.

0:09:430:09:47

If you were to start from scratch

0:09:470:09:49

and design a mammal that was built for flat-out sprint speed,

0:09:490:09:52

you'd come up with something that looked like a cheetah.

0:09:520:09:56

All of those adaptations, that exquisite body shape

0:09:560:09:59

mean they can be successful in as much as 50% of their hunts.

0:09:590:10:03

The gazelle's sharp manoeuvring, stamina

0:10:030:10:07

and agility made sure he gave the cheetah the run-around.

0:10:070:10:11

But today, the cheetah's sensational speed,

0:10:110:10:14

eyesight and hooked claws made sure she got the kill.

0:10:140:10:18

Now onto our next pair of hunters, locked in a battle for survival.

0:10:250:10:29

It's the biggest of all the big cats - the tiger.

0:10:290:10:34

Reaching up to three and half metres and weighing in perhaps 300kg,

0:10:340:10:38

they really are the heavyweight of the cat world.

0:10:380:10:40

And up against it is this.

0:10:400:10:44

The chital deer. Just like the gazelle, it's swift and agile

0:10:440:10:48

and will be tricky to catch.

0:10:480:10:50

But which has the edge in the race for life?

0:10:500:10:53

It's time to go Deadly 360.

0:10:530:10:55

We join the hunt at a critical time.

0:11:000:11:03

The tiger's hurtling at full stretch towards the deer,

0:11:030:11:06

closing down the gap with every enormous stride.

0:11:060:11:09

These deer are in a race for their lives.

0:11:110:11:14

So if we freeze the action at this crucial moment,

0:11:160:11:19

who do the odds favour? The predator or the prey?

0:11:190:11:22

Well, to find out, let's take it back to the start

0:11:220:11:25

and examine the hunt in forensic detail.

0:11:250:11:29

First though, where are we?

0:11:290:11:32

From the savannahs of East Africa we're now travelling

0:11:320:11:35

to the hot, dry forests of central India.

0:11:350:11:37

That means woodland and thicker vegetation.

0:11:370:11:40

No use for a cheetah,

0:11:400:11:42

but for the tiger, this is the perfect environment.

0:11:420:11:45

It's the height of the dry season and temperatures are scorching,

0:11:450:11:49

so hunting is difficult and dangerous.

0:11:490:11:52

And this is one of its favourite meals - the chital.

0:11:560:12:00

The forests are fantastic feeding grounds for these deer.

0:12:000:12:03

They graze in large herds on the long grass and on the leaves.

0:12:030:12:06

So, that's the location. Let's meet the animals.

0:12:090:12:12

So, what are the tigers weapons?

0:12:140:12:15

Well, firstly, its distinctive coat. Its black, white and orange stripes

0:12:150:12:20

are perfect camouflage for stalking its prey.

0:12:200:12:23

Next is its power and strength, weighing up to 300kg

0:12:230:12:27

and able to jump a whopping six metres.

0:12:270:12:30

And let's not forget those teeth.

0:12:320:12:36

Long and pointed, they can pierce through flesh with frightening ease.

0:12:360:12:40

All of this makes our predator a pretty scary prospect.

0:12:400:12:44

What does our prey animal have to counter?

0:12:440:12:47

Well, this is a deer that will leap, lunge and lurch its way

0:12:470:12:50

out of danger.

0:12:500:12:52

And it may not have size or strength on its side, but it is fast.

0:12:520:12:56

With its light frame, it can reach speeds of 40mph.

0:12:560:13:01

Add to this its incredible hearing and some lookouts

0:13:010:13:04

up in the trees, and this is certainly not an easy meal.

0:13:040:13:07

So we have two very different animals.

0:13:070:13:10

But which one's going to come out top in this hunt?

0:13:100:13:13

Let's find out.

0:13:130:13:14

We join the hunt with the tiger already having spotted the deer.

0:13:170:13:21

He's using his camouflage to stay hidden and out of sight.

0:13:220:13:25

You might think that orange with black and white stripes

0:13:250:13:29

isn't great camouflage, but you can hardly see him.

0:13:290:13:32

He blends right into the grass.

0:13:320:13:34

It's this cover that's crucial for the tiger.

0:13:340:13:37

He weighs about six times as much as a cheetah,

0:13:390:13:43

so he can't sustain a sprint over longer distances.

0:13:430:13:46

Getting as close as he can before springing an attack is vital.

0:13:460:13:49

But he doesn't just use stealth to stalk his prey,

0:13:490:13:52

he also relies on his eyesight.

0:13:520:13:55

Like most predators, like the cheetah we saw,

0:13:550:13:58

tigers have binocular vision.

0:13:580:14:00

This is the part of their sight where the vision from each eye

0:14:000:14:03

overlaps and it means that they're phenomenally good

0:14:030:14:05

at judging distance and space and movement.

0:14:050:14:08

Really important when trying to creep up

0:14:080:14:10

on prey that's as sensitive as these deer.

0:14:100:14:13

The tiger's just 20 metres away,

0:14:150:14:17

but being this close needs extreme care.

0:14:170:14:19

If the tiger strays upwind of the deer,

0:14:190:14:22

they'll smell him.

0:14:220:14:24

It's so dry, that moving through this crackling grass

0:14:240:14:27

is like walking on Corn Flakes.

0:14:270:14:29

A nightmare when you're trying to keep quiet.

0:14:290:14:32

The chital deer are always alert for the possible presence of a predator

0:14:350:14:39

and maybe the most sensitive sense is their hearing.

0:14:390:14:43

Look at the size of their ears,

0:14:430:14:45

they function like satellite dishes. They have one flicking forwards

0:14:450:14:48

and the other flicking backwards, always listening out for a sound

0:14:480:14:52

that could mean danger.

0:14:520:14:53

How will our tiger have the element of surprise

0:14:530:14:56

creeping up on these animals that are listening out for it?

0:14:560:14:59

Let's take a closer look at what's going on in his body.

0:14:590:15:02

There are very few more dramatic spectacles

0:15:050:15:07

than a tiger in full flight.

0:15:070:15:10

Everything about this animal just exudes muscularity.

0:15:100:15:14

After all, a fully grown male could weigh three times more than I do.

0:15:140:15:19

It's this muscular build that allows the tiger to spring

0:15:190:15:22

from a standing start, giving it the advantage over its prey.

0:15:220:15:26

Massive muscles launch it forward at breakneck speed,

0:15:260:15:29

accelerating up to 35mph in a matter of seconds.

0:15:290:15:33

And every single leap, every bound,

0:15:340:15:37

is going to put enormous stress on its skeleton

0:15:370:15:40

so the bones are huge and a lot of that is down to shock absorption.

0:15:400:15:44

It has that wonderful flexing gait.

0:15:450:15:48

You can see the spine there is bending as it runs,

0:15:480:15:51

the legs are extending out

0:15:510:15:52

in quite a similar method to the cheetah.

0:15:520:15:55

But if we compare the two,

0:15:550:15:57

it's much more slender, much more fragile.

0:15:570:16:01

In fact, the cheetah could be a tenth of the body weight of a tiger.

0:16:010:16:05

So, while the cheetah is built to be able to maintain its chase

0:16:060:16:10

over several hundreds metres,

0:16:100:16:12

all of this size, bulk, power,

0:16:120:16:15

muscularity of the tiger comes with a price.

0:16:150:16:18

If the chase isn't going to be over almost instantaneously,

0:16:180:16:21

the tiger is simply going to have to give up.

0:16:210:16:25

Right, back to the hunt.

0:16:250:16:27

This is the critical moment.

0:16:270:16:30

One wrong move now and it's all over.

0:16:300:16:32

The tiger edges slowly forward,

0:16:320:16:35

but in doing so reveals his location.

0:16:350:16:38

He's been detected by the monkeys and the deer. The alarm's raised.

0:16:380:16:42

Now everyone's on high alert.

0:16:420:16:46

Preparing for escape, the deer's body creates

0:16:460:16:48

chemicals like adrenalin

0:16:480:16:50

and the brain sends signals to the heart to start pumping more blood

0:16:500:16:54

to the muscles so she's ready for her exertion.

0:16:540:16:57

She's ready to go, the chase is on.

0:16:570:16:59

The deer are off, bursting out of the blocks like sprinters.

0:17:000:17:05

Their fantastic acceleration

0:17:050:17:07

gives them a split second head start over the tiger.

0:17:070:17:10

The deer are capable of going from standing around feeding

0:17:100:17:14

to 40mph in a matter of seconds. But how do they manage that?

0:17:140:17:18

Most of the deer's propulsion is coming from its back legs.

0:17:180:17:22

This is the where the muscle bulk is located.

0:17:220:17:24

But also running down the back of those legs

0:17:240:17:27

are springy elastic tendons.

0:17:270:17:29

Every time the deer lands, it stores up energy in those,

0:17:290:17:33

which it then releases as it springs away.

0:17:330:17:35

Almost like a bouncing rubber ball. It's certainly very impressive.

0:17:350:17:39

Right, back to the hunt.

0:17:390:17:41

We're now in the final moments of the chase

0:17:430:17:45

and the tiger's flat out, using his massive strength and power

0:17:450:17:48

to close the gap on the deer.

0:17:480:17:50

He's covering enormous ground in a series of linked jumps.

0:17:500:17:54

And each one of those leaps could be as much as six metres long,

0:17:560:18:00

which is like me jumping the length of a small bus.

0:18:000:18:03

As the tiger gets to within reach, the deer's speed and agility kick in

0:18:050:18:09

and they pull away.

0:18:090:18:11

At this critical point, the tiger doesn't have the stamina to keep up.

0:18:110:18:16

His massive bulk and weight drags his speed down.

0:18:160:18:18

He cannot catch the deer and has to resign.

0:18:180:18:20

There are so many different variables to consider

0:18:240:18:27

when you're looking at a tiger hunt. The wind, weather,

0:18:270:18:30

surrounding vegetation, the prey animal.

0:18:300:18:32

It's impossible to determine what the success rate will be.

0:18:320:18:36

That can vary from 50% success, which is pretty good,

0:18:360:18:39

right down to just 5% success and this time our tiger did not succeed.

0:18:390:18:44

So, the tiger may have camouflage,

0:18:450:18:48

power and super-sharp teeth...

0:18:480:18:51

..but today, the deer's speed, athletic agility

0:18:550:18:59

and keen hearing gave it the edge and left the tiger for dust.

0:18:590:19:02

This is our last deadly duo locked in a battle for life or death.

0:19:070:19:11

This is the iconic lion.

0:19:120:19:16

It can approach the size of the tiger in terms of size,

0:19:160:19:20

weighing as much as three men. And up against it is this.

0:19:200:19:23

The unmistakable zebra.

0:19:230:19:25

But which has the edge in the race for life?

0:19:270:19:30

It's time to go Deadly 360.

0:19:300:19:33

So, once again, we pick up this hunt in the final stages,

0:19:380:19:41

as the lions zip towards their prey.

0:19:410:19:45

zebras are masters of confusion,

0:19:450:19:47

but right now it looks like they're in serious trouble.

0:19:470:19:52

OK, it's just about to leap.

0:19:520:19:55

But by now, you know there's a lot more to a hunt

0:19:550:19:58

than just the final strike.

0:19:580:20:00

What are the hidden factors

0:20:000:20:01

that influence what will happen in the next few seconds?

0:20:010:20:04

To find out, we need to wind back to the start

0:20:040:20:07

and dissect the hunt.

0:20:070:20:09

First, though, where's this drama taking place?

0:20:100:20:15

We're going back to the savannah of East Africa and to the Masai Mara

0:20:150:20:19

but this time we're heading close to the Mara River.

0:20:190:20:21

This is prime hunting territory for lions.

0:20:240:20:27

Lions are the most social of the cat family,

0:20:270:20:29

living in prides of up to 40 animals.

0:20:290:20:32

Hunting is done together as a pride,

0:20:320:20:34

but the lionesses do the majority of the hunting,

0:20:340:20:37

being lighter and more agile.

0:20:370:20:39

These areas of the savannah

0:20:390:20:41

are alive with mammals like zebra.

0:20:410:20:44

Zebra live in large herds

0:20:440:20:46

moving across the grasslands in search of food and water.

0:20:460:20:50

But this dependency on water makes them vulnerable to predators.

0:20:500:20:54

So, that's the scene set.

0:20:550:20:57

Let's have a look at some of our predator's attributes.

0:20:570:21:00

Firstly, the lion's power and strength.

0:21:000:21:04

Pretty handy when your prey is twice your size.

0:21:040:21:06

Next, hunting in groups, using intelligent team tactics.

0:21:080:21:13

Add to that short, powerful jaws with fearsome crushing power

0:21:130:21:16

and this is one top cat!

0:21:160:21:18

It looks like we're dealing with a sophisticated hunter.

0:21:210:21:24

How on earth can the prey stay out of this predator's clutches?

0:21:240:21:27

Maybe a zebra's most valuable weapon

0:21:310:21:33

is their black and white stripes.

0:21:330:21:35

Camouflage at its most confusing.

0:21:350:21:37

And next, their speed.

0:21:380:21:40

They can accelerate up to 35 miles an hour

0:21:400:21:43

and have superior stamina over longer distances.

0:21:430:21:46

And last, their hard-hitting hooves,

0:21:470:21:49

delivering a punch that can injure and potentially kill an attacker.

0:21:490:21:54

So our predator's going to find it pretty difficult

0:21:540:21:57

to get anywhere near this prey.

0:21:570:21:59

Let's see what happens.

0:21:590:22:01

We join the hunt.

0:22:010:22:02

The lionesses have already spotted the zebra at the watering hole

0:22:020:22:06

but they're keeping out of sight.

0:22:060:22:08

Much like the tiger, the lion is all about muscularity.

0:22:100:22:14

It needs the hunt to be short, sharp, decisive.

0:22:140:22:17

If we look at the action from above...

0:22:170:22:20

You can see the lionesses

0:22:210:22:23

moving silently towards the zebra,

0:22:230:22:25

taking up a horseshoe formation around it.

0:22:250:22:28

This is a perfect ambush.

0:22:280:22:30

They're all experienced hunters

0:22:300:22:32

and know instinctively where the other animals will be.

0:22:320:22:35

Now just look at this sinuous movement.

0:22:350:22:39

The lioness is the master of stalking,

0:22:390:22:41

perfectly adapted for creeping low along the ground.

0:22:410:22:46

OK, let's see how it manages to do that.

0:22:460:22:48

A lion's eyes are set high on its head,

0:22:480:22:51

so even when it's crawling along on its belly, it can still see.

0:22:510:22:54

Just fantastic.

0:22:540:22:56

If we go back to our aerial view,

0:22:560:22:59

we can see their stalking skills

0:22:590:23:01

have got them in an ambush position around the zebra.

0:23:010:23:04

But although all the lionesses need to work together as a team to hunt,

0:23:040:23:08

they only need one individual

0:23:080:23:10

to bring down a zebra.

0:23:100:23:12

Let's think about what's going on here.

0:23:120:23:14

The lion needs to get really close

0:23:140:23:16

to allow its spring and acceleration to come into play.

0:23:160:23:19

But look at the size of these zebras. This is a powerful animal.

0:23:190:23:23

To bring one of these down, you need to be really strong.

0:23:230:23:26

So what physical attributes does the lion have

0:23:260:23:30

that makes all this possible?

0:23:300:23:31

This is an animal that kills through brute force,

0:23:310:23:34

and this skull is just massive.

0:23:340:23:38

The most obvious thing to say about it is, it's incredibly heavy.

0:23:380:23:43

That's because it has very, very thick bone,

0:23:430:23:46

particularly here, encasing and protecting the brain,

0:23:460:23:49

also here at the jaw.

0:23:490:23:51

But when it comes to the final bite,

0:23:510:23:54

it has these at its disposal.

0:23:540:23:57

Look at the size of those canine teeth.

0:23:570:23:59

They're pretty much the size of my thumbs.

0:23:590:24:02

Very broad, long, and pointed at the end.

0:24:020:24:05

This gives it the advantage that the lion can make a killing blow

0:24:050:24:08

almost anywhere on its opponent.

0:24:080:24:10

So with all that in mind,

0:24:100:24:12

let's go back to the hunt.

0:24:120:24:14

The lionesses are ready to strike.

0:24:160:24:19

Prepare for a masterclass in teamwork.

0:24:190:24:22

In a split second, the lead lionesses take off,

0:24:230:24:26

getting up to 35 miles an hour in seconds.

0:24:260:24:29

But with the zebra now in motion,

0:24:290:24:31

the lionesses have to pick one out on the run

0:24:310:24:34

and that's not going to be easy.

0:24:340:24:36

The zebra's distinctive black and white striped colouration

0:24:390:24:43

looks dramatic, even beautiful, but believe it or not,

0:24:430:24:46

it's one of its chief defences against lions.

0:24:460:24:48

I'll show you how it works.

0:24:480:24:50

A lion's colour vision is nothing like as good as our own.

0:24:530:24:57

This is what a lion would see if looking at a herd on the horizon.

0:24:570:25:00

It's pretty confusing.

0:25:000:25:01

So for a start, these animals are much more likely

0:25:010:25:04

to blend into the wavy lines of the grasses of their background.

0:25:040:25:08

But it's much more than that.

0:25:080:25:10

Once a zebra herd starts a stampede,

0:25:100:25:12

it's almost impossible for a lion to pick out an individual animal,

0:25:120:25:16

and that's a very important part of the lion's hunting strategy.

0:25:160:25:19

Let's see how this drama plays out.

0:25:190:25:22

The lionesses are in pursuit of the zebra.

0:25:260:25:29

This senior lioness singles one out from the group and heads in on it.

0:25:290:25:33

With the zebra isolated, its striped defence is useless

0:25:340:25:37

and the lioness seizes her opportunity.

0:25:370:25:39

Ooh! That was nasty.

0:25:430:25:45

Let's just check that out again.

0:25:450:25:47

OK, you can see now the lioness has chosen her target,

0:25:470:25:50

but at the last second,

0:25:500:25:52

it's a total miscalculation.

0:25:520:25:54

It looks like she's heading for the rump, but instead

0:25:540:25:56

she's ended up getting kicked

0:25:560:25:58

and then trampled.

0:25:580:25:59

This could be really, really serious.

0:25:590:26:01

Like all members of the horse family,

0:26:010:26:04

zebras have phenomenally powerful kicks.

0:26:040:26:06

They could easily fracture a lion's skull,

0:26:060:26:09

perhaps cause an injury that could eventually kill them.

0:26:090:26:12

So really, this time it looks like she's escaped pretty well.

0:26:120:26:16

Right, back to the hunt.

0:26:160:26:18

While the first lioness recovers,

0:26:200:26:22

another takes up the chase,

0:26:220:26:24

coming in from a different angle.

0:26:240:26:28

She blindsides the panicked, fleeing animal,

0:26:280:26:30

engages her retractable claws,

0:26:300:26:32

hooking into and holding onto the prey.

0:26:320:26:35

Now the difficult part. She has to use all her power and strength

0:26:350:26:39

to overwhelm the zebra.

0:26:390:26:40

But after just a few seconds,

0:26:400:26:43

she's successful, and delivers her killer bite.

0:26:430:26:47

Although working together in a pride

0:26:510:26:53

means food has to be shared at the end of the day,

0:26:530:26:55

this is a much more effective way of catching prey.

0:26:550:26:59

It's reckoned the odds are 1 in 3 if you're working together as a group

0:26:590:27:03

and 1 in 5 when working alone.

0:27:030:27:05

So ultimately, the pride is more successful.

0:27:050:27:08

The zebra's defensive strategy

0:27:080:27:10

of deceptive design,

0:27:100:27:12

swift speed and a killer kick

0:27:120:27:15

paid off initially.

0:27:150:27:16

But with their incredible muscle power,

0:27:180:27:20

lethal jaws

0:27:200:27:22

and tactical teamwork,

0:27:220:27:24

the lionesses were eventually successful.

0:27:240:27:27

The big cats are probably the most iconic and exciting of all predators

0:27:300:27:35

and whether they're killing in a flat-out foot race,

0:27:350:27:38

from a silent ambush, or working together as a team,

0:27:380:27:41

their predatory skills are simply not in question.

0:27:410:27:44

That's all we've got time for.

0:27:440:27:46

Join us next time, as three more pairs of animals go head to head

0:27:460:27:50

and we analyse the action Deadly 360 style.
