My name's Steve Backshall!

0:00:020:00:03

You can call me Steve.

0:00:030:00:07

I'm on a mission to find the Deadly 60 -

0:00:090:00:12

that's 60 deadly creatures.

0:00:120:00:14

I'm travelling all over the world.

0:00:140:00:16

And you're coming with me every step of the way.

0:00:160:00:20

-HISSING

-Shark!

0:00:220:00:24

Aaah!

0:00:250:00:27

I'm on the search for animals to add to my Deadly 60 list.

0:00:290:00:32

Not all will be deadly to humans,

0:00:320:00:34

but they'll all be deadly in their own world.

0:00:340:00:37

We've come to Australia,

0:00:370:00:39

a continent that has so many lethal contenders

0:00:390:00:42

that I'm having to scour both the sea and the land.

0:00:420:00:45

It truly is an awesome place to see wildlife.

0:00:470:00:50

The sea is stuffed full of incredible creatures

0:00:500:00:53

all busy catching and killing each other.

0:00:530:00:56

And then there's the spiders.

0:01:020:01:05

Australia has more deadly spiders than anywhere else in the world.

0:01:050:01:09

And, of course, there's the crocs.

0:01:140:01:18

Australia can also boast

0:01:180:01:19

five of the top ten most venomous snakes in the world.

0:01:190:01:23

I'm gonna start my search here with one of them -

0:01:230:01:26

the highly venomous tiger snake.

0:01:260:01:28

Where better to start than a typical Aussie back yard?

0:01:280:01:32

I'm in the outskirts of Perth,

0:01:370:01:39

the largest city in Western Australia,

0:01:390:01:41

but this being Australia,

0:01:410:01:43

there's bound to be some contenders for my Deadly 60

0:01:430:01:46

even in people's back yards.

0:01:460:01:47

-Hi, Mitch. How are you doing?

-How you going, Steve?

0:01:470:01:50

Pretty good. This is a fantastic back yard - a good place to search.

0:01:500:01:53

We're gonna have an easy time catching things.

0:01:530:01:56

Excellent! Let's go look.

0:01:560:01:58

'This is Mitch Ladyman, and he's just bonkers about snakes.'

0:01:580:02:03

Basically, you know, to other people, it's rubbish,

0:02:050:02:09

but it's habitat for the animals.

0:02:090:02:12

I've gotta say,

0:02:120:02:13

this stuff here is perfect material for reptiles.

0:02:130:02:16

If any of you are wanting to have a wild corner of your garden

0:02:160:02:19

to attract slowworms, grass snakes, that kind of thing,

0:02:190:02:22

laying down a bit of corrugated iron like this is just perfect

0:02:220:02:26

because the snakes are attracted to lie underneath it

0:02:260:02:29

cos it generates warmth,

0:02:290:02:31

so I'm guessing that's why you've got this lot.

0:02:310:02:33

No, I'm doing a bit of building(!) STEVE LAUGHS

0:02:330:02:38

-Mate, you actually have a dunny!

-Well...

0:02:380:02:41

Have a look at the view! I mean...

0:02:410:02:44

An archetypal image of Australia is the outdoors toilet, or dunny.

0:02:440:02:49

Have a look in there!

0:02:490:02:51

Just picture yourself with a newspaper, sun shining,

0:02:510:02:55

birds are singing.

0:02:550:02:56

Oh! Mate, that's a throne!

0:02:560:02:59

-Made for you!

-I love it! 'Yeah, thanks, Mitch!

0:02:590:03:02

'I think I'll wait till the cameras are off!'

0:03:020:03:04

One of the cardinal rules... of doing stuff like this

0:03:040:03:08

is never to put your fingers

0:03:080:03:10

where you can't see what's underneath them.

0:03:100:03:12

And that's particularly true here in Australia

0:03:120:03:16

where there's an awful lot of things that can give you a nasty bite.

0:03:160:03:20

It's just so hard to find things.

0:03:200:03:22

An infinite amount of places for things to hide.

0:03:220:03:25

-Oh, look, look, look!

-Oh, oh, oh!

0:03:270:03:29

-Woah!

-Oh-ho! Good catch!

0:03:300:03:34

Oh, dear! Don't bite!

0:03:340:03:36

Grumpy! Oh!

0:03:360:03:39

-Thought that was a tiger snake for a second!

-Well done! So did I!

0:03:410:03:45

You saw that black form and thought, "Here we go!"

0:03:450:03:48

-Is this a king's skink?

-Yeah, mate, Egernia kingii.

0:03:480:03:51

Most people think they're like a coastal skink.

0:03:510:03:54

They hang out a lot on the limestone cliffs on the coast.

0:03:540:03:58

You can still get them on the local beaches

0:03:580:04:00

down in Perth's local foreshore.

0:04:000:04:03

Really robust - they eat insects, vegetation, all-sorts of stuff.

0:04:030:04:07

-Really quite strong, so...

-Yeah.

0:04:070:04:09

..pretty much eat whatever comes along.

0:04:090:04:11

He is wonderful!

0:04:110:04:12

They don't hurt.

0:04:120:04:14

If you let them bite on... they'll bite...

0:04:140:04:17

Let go.

0:04:170:04:18

Woah!

0:04:180:04:20

-They'll let go...

-Look at that!

-..when they realise it's pointless.

0:04:200:04:24

That's great stuff!

0:04:240:04:26

-So, the jaw is incredibly powerful...

-Heaps powerful.

0:04:260:04:30

Ow!

0:04:310:04:32

That REALLY hurts!

0:04:320:04:35

I can't believe you just made me do that!

0:04:350:04:38

I knew what I was getting in for.

0:04:380:04:40

I think it surprises half of the, er...

0:04:400:04:43

-Let go, please!

-STEVE CHUCKLES

0:04:430:04:46

If you can imagine that on your knuckle or something like that,

0:04:460:04:49

so much more painful.

0:04:490:04:51

-He's starting to settle down now.

-Yeah.

0:04:510:04:53

-That is wonderful.

-Yeah, he's so cute.

-Yeah.

0:04:530:04:56

Well, he's pretty good,

0:04:560:04:58

but he's not going on my Deadly 60.

0:04:580:05:00

Look at that - he grabbed hold of my hand, didn't even make me bleed!

0:05:000:05:04

'So, if you get giant skinks in your back yard,

0:05:070:05:09

'what's lurking in the local park?

0:05:090:05:12

'I'm hoping for tiger snakes!'

0:05:120:05:14

Despite the fact that we are so close to all these houses,

0:05:160:05:19

this really is fantastic habitat for tiger snakes,

0:05:190:05:22

mostly because there's so much water, so many reeds, long grasses,

0:05:220:05:26

and that's perfect habitat for their main prey source, which is frogs.

0:05:260:05:30

If you're a snake and these super-fast frogs are on the menu,

0:05:300:05:33

then you want to be able to kill them quickly

0:05:330:05:35

so they don't hop away and leave you hungry.

0:05:350:05:38

That's exactly why the tiger snake's venom is SO strong

0:05:380:05:41

and fast-acting.

0:05:410:05:43

One bite and it's game over.

0:05:430:05:45

It's one thing to stop a frog dead in its tracks,

0:05:470:05:50

but here's the scary thing -

0:05:500:05:51

there's enough lethal venom in one bite from a tiger snake

0:05:510:05:54

to kill a handful of people.

0:05:540:05:57

Imagine you tread on one and it bites you.

0:05:570:05:59

The bite itself wouldn't feel that bad,

0:05:590:06:03

but inside your body, it's a very different story.

0:06:030:06:06

At first, your nerves stop firing

0:06:060:06:09

and you feel a tingling in your hands and feet,

0:06:090:06:11

then your muscles stop functioning properly,

0:06:110:06:14

you can't keep your eyes open and your throat starts to close.

0:06:140:06:18

Paralysis sets in.

0:06:180:06:19

Other toxins in the venom dissolve and eat your muscles.

0:06:190:06:22

It gets harder to move.

0:06:220:06:24

Meanwhile, your blood is being thickened into sticky clumps,

0:06:240:06:28

and as all the effects of the toxin combine, the organs start failing.

0:06:280:06:32

The muscles round your lungs seize up and you stop breathing.

0:06:320:06:36

If you don't get help in the form of anti-venom,

0:06:360:06:39

it could all be over within an hour.

0:06:390:06:40

You might think we're crazy to go looking for tiger snakes.

0:06:400:06:44

But both Mitch and I have been working with snakes for years.

0:06:440:06:47

We're all rooting for you!

0:06:470:06:49

-Yeah, yeah!

-This way, mate.

0:06:490:06:51

STEVE SIGHS

0:06:510:06:55

Follow me, mate, you're more likely to catch something.

0:06:550:06:58

Get stuffed!

0:06:580:06:59

That's a good patch.

0:06:590:07:01

These basking platforms, they're perfect,

0:07:010:07:03

-cos they'll sit on there...

-Good!

0:07:030:07:05

Oh, yeah, trying to get in front! I can run too!

0:07:050:07:10

Normally, I'd be going really slowly, really gently,

0:07:110:07:15

but because I'm all competitive, I'm half-running along!

0:07:150:07:18

To be honest, it's the best way,

0:07:180:07:21

because, really, the longer we take to come on top of them,

0:07:210:07:24

-the more chance they've got of getting away.

-Yeah.

0:07:240:07:26

They are quite sensitive to disturbance,

0:07:260:07:29

so I've found, when I was doing research,

0:07:290:07:33

that walking at a good pace,

0:07:330:07:34

you know, all you're basically looking out for

0:07:340:07:37

is a black pile of shiny skin, so it's not like they're difficult,

0:07:370:07:42

and so you're better off just covering more ground.

0:07:420:07:45

Ah, got one!

0:07:450:07:46

'This method might look a bit gung-ho,

0:07:460:07:48

'but we're deadly serious.

0:07:480:07:50

'Using a snake hook like this keeps me at a safe distance

0:07:500:07:53

'and is also the gentlest way to handle the snake.'

0:07:530:07:56

It's all right, it's all right!

0:07:560:07:58

There's nothing worse than being patronised by an Australian!

0:07:580:08:01

THEY LAUGH

0:08:010:08:03

So... There's another one.

0:08:030:08:05

Yep, all right... That's...

0:08:060:08:08

-Get a hook...

-Get out the way...

0:08:080:08:09

MITCH LAUGHS

0:08:090:08:11

I...

0:08:130:08:14

Didn't say a word, wasn't me!

0:08:140:08:15

Here's one.

0:08:150:08:17

Ah, this is just getting unfair.

0:08:180:08:20

See, the problem is, Steve, you SEE them, you gotta CATCH them.

0:08:200:08:23

I was waiting for Mark to go in and film it!

0:08:230:08:25

I was waiting for you to throw it at me!

0:08:250:08:29

There's one, right at the side here.

0:08:290:08:31

-Back off, back off!

-Two, two, two!

0:08:310:08:33

There was two, that's why I couldn't grab it. There was two.

0:08:330:08:36

See that, basking together?

0:08:360:08:38

I just launched down, I thought, "There's too many coils there!"

0:08:380:08:42

Nearly had it!

0:08:420:08:44

This is a big one. It IS a big one.

0:08:440:08:45

And it's gone.

0:08:470:08:48

-Yep, there you go.

-There's one.

0:08:540:08:56

All right, whip it out.

0:08:560:08:57

Go on, get it, get it, get it!

0:08:590:09:00

Gone.

0:09:000:09:01

Wahey! Good save!

0:09:010:09:04

I got it, I got it.

0:09:040:09:06

-Oh! Well done!

-Finally!

-OK...

0:09:060:09:09

We've been looking for... probably five minutes.

0:09:090:09:13

-Maybe two!

-This is incredible!

-Yeah!

0:09:130:09:17

We are right on the outskirts

0:09:170:09:18

of the biggest city in Western Australia

0:09:180:09:21

-and I have in my hand...

-Watch it.

0:09:210:09:24

..the fourth most toxic venomous snake in the world -

0:09:240:09:27

the tiger snake.

0:09:270:09:29

-Mitch, this is an absolute beauty.

-Yeah, it's cute.

0:09:290:09:32

Cute?! Only an Australian could describe a tiger snake as cute!

0:09:320:09:37

This is a snake

0:09:370:09:39

that needs to be treated with an amazing amount of respect

0:09:390:09:42

because drop by drop,

0:09:420:09:43

its venom is far more toxic than any of the cobras,

0:09:430:09:47

far more toxic than a king cobra, than a black mamba...

0:09:470:09:50

This has enough venom to bring down...

0:09:500:09:52

Mitch and I and probably the rest of the film crew as well.

0:09:520:09:56

But as you can see,

0:09:560:09:58

he has absolutely no interest in striking whatsoever.

0:09:580:10:01

What's wonderful about this

0:10:010:10:03

is that tiger snakes are in the same family as the cobras -

0:10:030:10:06

they're called elapids -

0:10:060:10:08

and you can actually see that it does have a hood.

0:10:080:10:11

It'll spread its body sideways,

0:10:110:10:13

making itself seem bigger that it actually is,

0:10:130:10:16

and standing a good portion of its body up off the ground as well.

0:10:160:10:20

-That is a classic cobra shape, isn't it?

-Yeah.

0:10:200:10:22

For me, the reason the tiger snake is such an amazing predator

0:10:220:10:28

is just that it kills its prey so quickly, you know?

0:10:280:10:31

If you're feeding on a frog,

0:10:310:10:33

the last thing you want is to bite it,

0:10:330:10:35

for it to disappear into the reeds and you never find it again.

0:10:350:10:38

But if a tiger snake bites a frog, it's got minutes to live.

0:10:380:10:41

What you can see here...

0:10:410:10:43

Tiger snakes commonly have a reputation for charging people,

0:10:430:10:48

but you can see where that misconception comes from.

0:10:480:10:51

All this snake wants to do... is go straight back into the bush.

0:10:510:10:56

At the moment, he's heading straight for between my legs.

0:10:560:10:59

Just let him go.

0:10:590:11:01

This is the amount of confidence that I have...

0:11:010:11:04

..in this snake and its behaviour.

0:11:070:11:09

There's no way he was gonna bite me.

0:11:090:11:11

Heading off into the grass.

0:11:110:11:13

That is absolutely fantastic.

0:11:130:11:15

The thing that really gets me about this

0:11:160:11:19

is the fact that we've seen people wandering through here,

0:11:190:11:23

there's houses right there, but nobody here ever gets bitten.

0:11:230:11:26

In all the time I've been here, wandering around, like we're doing,

0:11:260:11:30

I'll actually have people pull over on their pushies, their push-bikes,

0:11:300:11:34

or stop while they're jogging in absolute disbelief,

0:11:340:11:38

and they say, "What are you doing?"

0:11:380:11:40

I say, "I'm studying tiger snakes."

0:11:400:11:42

They have no idea.

0:11:420:11:44

And the reason is, is because, this... I mean,

0:11:440:11:48

they're sitting along the edge in the vegetation,

0:11:480:11:51

minding their own business...

0:11:510:11:52

-The second anyone gets too close...

-Yep, they disappear.

0:11:520:11:55

As soon as he knows he's safe, he'll pick up speed

0:11:580:12:02

and he'll shoot into that bush like nobody's business.

0:12:020:12:05

Look at that, wonderful.

0:12:070:12:09

Excellent!

0:12:090:12:12

I have never seen anywhere with so many venomous snakes

0:12:120:12:15

this close to so many people.

0:12:150:12:17

With one of the most potent venoms on the planet,

0:12:190:12:21

a tiger snake can kill its frog prey in minutes.

0:12:210:12:24

And that's why it's going on the Deadly 60.

0:12:240:12:28

Time to get wet and check out some deadly predators in the sea.

0:12:350:12:39

This may sound obvious, but if you're a predator,

0:12:390:12:42

the main benefit to living in the sea is fish.

0:12:420:12:45

Beneath me, there could be huge, shimmering shoals of fish,

0:12:450:12:49

packed full of protein.

0:12:490:12:51

My next contender to the Deadly 60 are all masters at catching fish,

0:12:510:12:54

but they all have very different ways of doing it.

0:12:540:12:58

Argh!

0:12:580:12:59

Woah-ha-ha!

0:13:110:13:14

Look at that!

0:13:140:13:17

As soon as they get in the water, they are transformed!

0:13:170:13:20

He turns from a sluggish big boulder on the beach into a torpedo!

0:13:200:13:27

Oh, you're just showing off now!

0:13:400:13:43

This might look like fun,

0:13:430:13:45

but try and imagine if you were a fish being hunted by this!

0:13:450:13:48

You wouldn't stand any chance at all.

0:13:480:13:51

Sea lions are formidable predators.

0:13:510:13:54

They are super-fast, reaching speeds of up to 40km an hour,

0:13:540:13:58

twisting and turning their whole bodies,

0:13:580:14:01

so they can even catch fish that are right behind them.

0:14:010:14:04

Check THAT out for deadly accuracy!

0:14:040:14:07

They have fantastic eyesight and ultra-sensitive whiskers

0:14:090:14:13

that can sense the tiniest of ripples made by fish.

0:14:130:14:17

All of these skills combine to make it a truly awesome predator.

0:14:170:14:21

Where are ya?!

0:14:210:14:23

He's behind me!

0:14:260:14:28

And he's underneath me!

0:14:280:14:30

There's another predator round here that has a very different strategy

0:14:340:14:38

for killing fish.

0:14:380:14:40

How am I supposed to get out of here?!

0:14:400:14:42

I'm not taking YOUR hand!

0:14:420:14:44

HE LAUGHS

0:14:460:14:48

-What you doing down there, Steve?!

-STEVE LAUGHS

0:14:500:14:53

There are two birds here that would

0:14:590:15:02

definitely be in contention for the Deadly 60.

0:15:020:15:04

The first ones are these cormorants down the front here,

0:15:040:15:07

but I think the birds up the top definitely have the edge -

0:15:070:15:11

they're pelicans.

0:15:110:15:12

I'm sure there's a fair few of you at home who are thinking,

0:15:160:15:20

"Steve has finally lost it.

0:15:200:15:22

"Pelicans - they're rubbish, they're like big, oversized ducks."

0:15:220:15:26

If you're one of those thinking that, have a look at this.

0:15:260:15:30

Brown pelicans cruise effortlessly looking for their next meal.

0:15:300:15:34

Once they've spotted their prey, they fold up their wings

0:15:340:15:37

and accelerate to speeds of up to 65km an hour,

0:15:370:15:40

hitting the water like a javelin.

0:15:400:15:44

It's a regular pelican pile-up.

0:15:490:15:51

Although they hit the water fast, they stop quickly,

0:15:510:15:56

because their lightweight skeleton

0:15:560:15:58

is packed with air spaces that keeps them buoyant.

0:15:580:16:01

One of their most dramatic physical characteristics

0:16:010:16:04

is their unbelievable bill. It's the longest of any bird.

0:16:040:16:08

What's particularly extraordinary about it,

0:16:250:16:28

you think of pelicans as having huge swollen sacks under their bills,

0:16:280:16:33

but you can see at the moment,

0:16:330:16:34

it's lying right flush against the underside of the bill.

0:16:340:16:38

What's amazing is that when they hit the water,

0:16:380:16:41

they fill that sack with an enormous amount of water.

0:16:410:16:44

If you're wondering quite how much that is,

0:16:510:16:53

I'm gonna try and show you with the help of my glamorous assistant,

0:16:530:16:57

Rich the sound man.

0:16:570:16:59

Rich, if you could just hold this bag out like this...

0:16:590:17:02

So if you imagine this is the sack underneath the bill of the pelican.

0:17:020:17:06

This is water.

0:17:080:17:10

One litre...

0:17:100:17:12

Here we go...

0:17:230:17:25

13 litres of water!

0:17:280:17:31

HE LAUGHS

0:17:310:17:33

I can barely carry it!

0:17:330:17:36

Can you imagine that hanging underneath the beak?!

0:17:360:17:39

That's incredible!

0:17:390:17:41

Fortunately for the pelicans, they don't have to carry it around.

0:17:430:17:47

What they do is squeeze all the water out before eating the fish.

0:17:470:17:51

That can take about a minute,

0:17:510:17:53

and other birds keep trying to steal the fish left behind,

0:17:530:17:56

but finally, they do get to gulp it down.

0:17:560:17:58

Often, you'll see pelicans flying right over the surface of the water

0:17:580:18:02

and they can fly like that for a very long time.

0:18:020:18:05

It's not because they're too lazy to get up high and fly,

0:18:050:18:08

but because it's a very economical way of keeping in the air.

0:18:080:18:11

If you think of...waves... as being like this -

0:18:110:18:17

this is my rubbish drawing -

0:18:170:18:19

as wind blows along the surface of the wave,

0:18:190:18:21

it's driven up by the wave itself.

0:18:210:18:24

What this does is create lift,

0:18:240:18:27

so if a bird flies across here, it gets carried up by the wind.

0:18:270:18:32

You can see them almost cruising along with their wing tips

0:18:320:18:36

just grazing the top of the water,

0:18:360:18:37

and they can fly like that for miles, barely expending any effort.

0:18:370:18:41

I've got a little experiment to try and show you how this works.

0:18:410:18:45

Our researcher, John, is a dab hand...

0:18:450:18:50

with making paper aeroplanes.

0:18:500:18:52

I'm gonna see if this will lift up when it flies over the waves.

0:18:520:18:57

Don't worry, I AM gonna go and get it.

0:18:570:19:00

Here goes with a disastrous experiment...

0:19:020:19:06

If this works well, as this wave comes in,

0:19:060:19:08

it should lift the dart up.

0:19:080:19:10

HE LAUGHS

0:19:100:19:14

Rats! Got another dart, John?!

0:19:140:19:17

-HE LAUGHS

-That was even worse!

0:19:190:19:22

You should write your name on it - whoever's flies best, wins!

0:19:220:19:25

It's the winner!

0:19:280:19:29

The crew has bombarded me with darts - one of them is gonna work!

0:19:320:19:37

Good luck, Steve!

0:19:370:19:39

Ooooh!

0:19:410:19:42

HE LAUGHS

0:19:420:19:45

No.

0:19:460:19:47

Sound man Richard's deadly 747.

0:19:470:19:51

Yeah! That is the winner!

0:19:530:19:56

That one went backwards!

0:19:560:20:00

We can fairly safely say my science experiment is rubbish,

0:20:000:20:03

but the pelicans do it a lot better.

0:20:030:20:06

Be under no illusions -

0:20:130:20:15

pelicans are killing machines.

0:20:150:20:17

They're large, fast and deadly accurate,

0:20:170:20:22

securing them a place on my Deadly 60.

0:20:220:20:25

Another day, another boat.

0:20:380:20:40

I'm on the trail of possibly the finest fish-finder in the seas.

0:20:400:20:44

It's an animal you're familiar with.

0:20:440:20:46

With its distinctive curved dorsal fin,

0:20:460:20:48

its sleek grey profile

0:20:480:20:51

and its brutally sharp teeth.

0:20:510:20:53

This could well be the most perfect predator in the Deadly 60.

0:20:530:20:58

But it's identity might come as a bit of a surprise.

0:20:580:21:01

I'll give you a clue - Sarah here is going to be my guide

0:21:010:21:04

and they call her the Dolphin Girl.

0:21:040:21:08

Literally, five minutes out of the dock and already

0:21:080:21:12

a whole bunch of bottlenose dolphins have popped up alongside.

0:21:120:21:17

There's about six or seven animals and they are so close.

0:21:170:21:20

These ones are right up at the bow.

0:21:200:21:22

This is a family group, known as a pod.

0:21:220:21:25

We're hoping that they want to stay and play.

0:21:250:21:29

So how come cute and cuddly dolphins

0:21:290:21:32

get to be contenders on my Deadly 60?

0:21:320:21:35

Well, just bear with me and I'll show you.

0:21:350:21:38

There are so many reasons why dolphins have to be on my Deadly 60.

0:21:390:21:42

First, their streamlined bodies and powerful tails

0:21:420:21:45

mean they're incredibly fast.

0:21:450:21:47

They can easily outstrip a boat like this

0:21:470:21:49

and they can jump 16 feet out of the water.

0:21:490:21:53

That's as high as our sound man's boom pole.

0:21:530:21:58

But the thing that really sets them apart

0:22:060:22:08

is that dolphins are incredibly brainy.

0:22:080:22:11

Look at this.

0:22:110:22:13

If you can imagine, this green jelly here is about the size

0:22:130:22:18

and the weight of a human brain

0:22:180:22:20

and this pink one,

0:22:200:22:23

which has kind of fallen apart

0:22:230:22:25

rather drastically

0:22:250:22:27

is a bit of an embarrassment, really.

0:22:270:22:29

But that's about the size of a dolphin brain.

0:22:290:22:32

Having a brain that big, being that intelligent

0:22:320:22:35

means that dolphins can work together in teams,

0:22:350:22:37

and come up with all kinds of different strategies

0:22:370:22:40

for catching fish.

0:22:400:22:42

Mmm.

0:22:450:22:46

Brains taste good.

0:22:460:22:49

Using that superior brain power to work together as a team

0:22:500:22:54

means they can come up with astonishing strategies

0:22:540:22:57

for catching fish.

0:22:570:22:59

Check out these dolphins in Florida.

0:22:590:23:02

That ring of muddy water was actually made by a dolphin

0:23:020:23:05

swimming along the bottom

0:23:050:23:07

to churn up the mud with its tail.

0:23:070:23:09

The ring encircles a shoal of fish,

0:23:090:23:11

the fish think they're trapped, and as they leap out to escape,

0:23:110:23:15

the other dolphins are lying in wait.

0:23:150:23:17

But the really amazing thing

0:23:220:23:25

is they all take turns to churn up the mud

0:23:250:23:27

so everyone gets a chance to grab a fish dinner

0:23:270:23:30

and have a bit of fun as well.

0:23:300:23:33

These dolphins have come up with a completely different technique.

0:23:400:23:44

They're not rushing up to the beach for a bit of fun.

0:23:460:23:49

They're herding fish out of the water so they're easier to catch

0:23:490:23:52

and that means stranding themselves,

0:23:520:23:55

which is a very risky thing for a dolphin to do,

0:23:550:23:58

but they choose beaches with just the right slope

0:23:580:24:01

so they can roll back safely after grabbing the fish.

0:24:010:24:04

Getting this right

0:24:040:24:06

takes not only intelligence but agility as well.

0:24:060:24:10

Finally, as well as chatting with their whistles and clicks,

0:24:170:24:20

dolphins use sound to find and catch their prey.

0:24:200:24:24

Bursts of ultrasound echo off anything solid in the water,

0:24:240:24:28

giving the dolphins a kind of sound picture

0:24:280:24:31

which they can even beam to each other,

0:24:310:24:34

a bit like e-mailing a photo,

0:24:340:24:36

but better.

0:24:360:24:37

Their ultrasound even penetrates the sand,

0:24:370:24:40

so there's nowhere to hide,

0:24:400:24:42

but in order to really see them properly,

0:24:420:24:45

I have to join them in their world.

0:24:450:24:47

I tell you what, I absolutely hate my job.

0:24:480:24:51

OK. Wish me luck, guys.

0:24:590:25:01

Good luck, Steve.

0:25:010:25:03

Get ready.

0:25:030:25:04

OK, guys, go!

0:25:040:25:06

These motorised sleds actually give you an idea

0:25:100:25:13

of what it's like to be a dolphin

0:25:130:25:15

and help us keep up with these beautiful streamlined animals.

0:25:150:25:18

It's frustrating, because we can't hold our breath

0:25:180:25:21

anywhere near as long as a dolphin, we need to keep coming up for air.

0:25:210:25:25

They also seem to be having as much fun as we are

0:25:250:25:28

and this is even more special because these are

0:25:280:25:31

really wild dolphins, and they're choosing to play with us.

0:25:310:25:34

This is out of this world!

0:25:340:25:37

I've never seen anything like it before in my life.

0:25:370:25:41

Just incredible.

0:25:410:25:43

Ah! That was out of this world!

0:26:370:26:40

And that's why dolphins are pretty much everyone's favourite animal.

0:26:400:26:44

But they're also fearsome hunters.

0:26:440:26:47

And that's why they're going on my Deadly 60.

0:26:470:26:50

Ultra-intelligent and adaptable,

0:26:570:26:58

perfectly streamlined and turbo-charged,

0:26:580:27:01

with built-in ultrasound and weapons systems,

0:27:010:27:04

dolphins have to be on my Deadly 60.

0:27:040:27:07

All in the name of science. Ow! That stung right through the suit.

0:27:100:27:13

Join me next time

0:27:130:27:15

as I continue my search for the Deadly 60.

0:27:150:27:18

Oh-ho! Getting up some speed now!

0:27:200:27:23

Sunlight here.
