My name's Steve Backshall! | 0:00:02 | 0:00:03 | |
You can call me Steve. | 0:00:03 | 0:00:07 | |
I'm on a mission to find the Deadly 60 - | 0:00:09 | 0:00:12 | |
that's 60 deadly creatures. | 0:00:12 | 0:00:14 | |
I'm travelling all over the world. | 0:00:14 | 0:00:16 | |
And you're coming with me every step of the way. | 0:00:16 | 0:00:20 | |
-HISSING -Shark! | 0:00:22 | 0:00:24 | |
Aaah! | 0:00:25 | 0:00:27 | |
I'm on the search for animals to add to my Deadly 60 list. | 0:00:29 | 0:00:32 | |
Not all will be deadly to humans, | 0:00:32 | 0:00:34 | |
but they'll all be deadly in their own world. | 0:00:34 | 0:00:37 | |
We've come to Australia, | 0:00:37 | 0:00:39 | |
a continent that has so many lethal contenders | 0:00:39 | 0:00:42 | |
that I'm having to scour both the sea and the land. | 0:00:42 | 0:00:45 | |
It truly is an awesome place to see wildlife. | 0:00:47 | 0:00:50 | |
The sea is stuffed full of incredible creatures | 0:00:50 | 0:00:53 | |
all busy catching and killing each other. | 0:00:53 | 0:00:56 | |
And then there's the spiders. | 0:01:02 | 0:01:05 | |
Australia has more deadly spiders than anywhere else in the world. | 0:01:05 | 0:01:09 | |
And, of course, there's the crocs. | 0:01:14 | 0:01:18 | |
Australia can also boast | 0:01:18 | 0:01:19 | |
five of the top ten most venomous snakes in the world. | 0:01:19 | 0:01:23 | |
I'm gonna start my search here with one of them - | 0:01:23 | 0:01:26 | |
the highly venomous tiger snake. | 0:01:26 | 0:01:28 | |
Where better to start than a typical Aussie back yard? | 0:01:28 | 0:01:32 | |
I'm in the outskirts of Perth, | 0:01:37 | 0:01:39 | |
the largest city in Western Australia, | 0:01:39 | 0:01:41 | |
but this being Australia, | 0:01:41 | 0:01:43 | |
there's bound to be some contenders for my Deadly 60 | 0:01:43 | 0:01:46 | |
even in people's back yards. | 0:01:46 | 0:01:47 | |
-Hi, Mitch. How are you doing? -How you going, Steve? | 0:01:47 | 0:01:50 | |
Pretty good. This is a fantastic back yard - a good place to search. | 0:01:50 | 0:01:53 | |
We're gonna have an easy time catching things. | 0:01:53 | 0:01:56 | |
Excellent! Let's go look. | 0:01:56 | 0:01:58 | |
'This is Mitch Ladyman, and he's just bonkers about snakes.' | 0:01:58 | 0:02:03 | |
Basically, you know, to other people, it's rubbish, | 0:02:05 | 0:02:09 | |
but it's habitat for the animals. | 0:02:09 | 0:02:12 | |
I've gotta say, | 0:02:12 | 0:02:13 | |
this stuff here is perfect material for reptiles. | 0:02:13 | 0:02:16 | |
If any of you are wanting to have a wild corner of your garden | 0:02:16 | 0:02:19 | |
to attract slowworms, grass snakes, that kind of thing, | 0:02:19 | 0:02:22 | |
laying down a bit of corrugated iron like this is just perfect | 0:02:22 | 0:02:26 | |
because the snakes are attracted to lie underneath it | 0:02:26 | 0:02:29 | |
cos it generates warmth, | 0:02:29 | 0:02:31 | |
so I'm guessing that's why you've got this lot. | 0:02:31 | 0:02:33 | |
No, I'm doing a bit of building(!) STEVE LAUGHS | 0:02:33 | 0:02:38 | |
-Mate, you actually have a dunny! -Well... | 0:02:38 | 0:02:41 | |
Have a look at the view! I mean... | 0:02:41 | 0:02:44 | |
An archetypal image of Australia is the outdoors toilet, or dunny. | 0:02:44 | 0:02:49 | |
Have a look in there! | 0:02:49 | 0:02:51 | |
Just picture yourself with a newspaper, sun shining, | 0:02:51 | 0:02:55 | |
birds are singing. | 0:02:55 | 0:02:56 | |
Oh! Mate, that's a throne! | 0:02:56 | 0:02:59 | |
-Made for you! -I love it! 'Yeah, thanks, Mitch! | 0:02:59 | 0:03:02 | |
'I think I'll wait till the cameras are off!' | 0:03:02 | 0:03:04 | |
One of the cardinal rules... of doing stuff like this | 0:03:04 | 0:03:08 | |
is never to put your fingers | 0:03:08 | 0:03:10 | |
where you can't see what's underneath them. | 0:03:10 | 0:03:12 | |
And that's particularly true here in Australia | 0:03:12 | 0:03:16 | |
where there's an awful lot of things that can give you a nasty bite. | 0:03:16 | 0:03:20 | |
It's just so hard to find things. | 0:03:20 | 0:03:22 | |
An infinite amount of places for things to hide. | 0:03:22 | 0:03:25 | |
-Oh, look, look, look! -Oh, oh, oh! | 0:03:27 | 0:03:29 | |
-Woah! -Oh-ho! Good catch! | 0:03:30 | 0:03:34 | |
Oh, dear! Don't bite! | 0:03:34 | 0:03:36 | |
Grumpy! Oh! | 0:03:36 | 0:03:39 | |
-Thought that was a tiger snake for a second! -Well done! So did I! | 0:03:41 | 0:03:45 | |
You saw that black form and thought, "Here we go!" | 0:03:45 | 0:03:48 | |
-Is this a king's skink? -Yeah, mate, Egernia kingii. | 0:03:48 | 0:03:51 | |
Most people think they're like a coastal skink. | 0:03:51 | 0:03:54 | |
They hang out a lot on the limestone cliffs on the coast. | 0:03:54 | 0:03:58 | |
You can still get them on the local beaches | 0:03:58 | 0:04:00 | |
down in Perth's local foreshore. | 0:04:00 | 0:04:03 | |
Really robust - they eat insects, vegetation, all-sorts of stuff. | 0:04:03 | 0:04:07 | |
-Really quite strong, so... -Yeah. | 0:04:07 | 0:04:09 | |
..pretty much eat whatever comes along. | 0:04:09 | 0:04:11 | |
He is wonderful! | 0:04:11 | 0:04:12 | |
They don't hurt. | 0:04:12 | 0:04:14 | |
If you let them bite on... they'll bite... | 0:04:14 | 0:04:17 | |
Let go. | 0:04:17 | 0:04:18 | |
Woah! | 0:04:18 | 0:04:20 | |
-They'll let go... -Look at that! -..when they realise it's pointless. | 0:04:20 | 0:04:24 | |
That's great stuff! | 0:04:24 | 0:04:26 | |
-So, the jaw is incredibly powerful... -Heaps powerful. | 0:04:26 | 0:04:30 | |
Ow! | 0:04:31 | 0:04:32 | |
That REALLY hurts! | 0:04:32 | 0:04:35 | |
I can't believe you just made me do that! | 0:04:35 | 0:04:38 | |
I knew what I was getting in for. | 0:04:38 | 0:04:40 | |
I think it surprises half of the, er... | 0:04:40 | 0:04:43 | |
-Let go, please! -STEVE CHUCKLES | 0:04:43 | 0:04:46 | |
If you can imagine that on your knuckle or something like that, | 0:04:46 | 0:04:49 | |
so much more painful. | 0:04:49 | 0:04:51 | |
-He's starting to settle down now. -Yeah. | 0:04:51 | 0:04:53 | |
-That is wonderful. -Yeah, he's so cute. -Yeah. | 0:04:53 | 0:04:56 | |
Well, he's pretty good, | 0:04:56 | 0:04:58 | |
but he's not going on my Deadly 60. | 0:04:58 | 0:05:00 | |
Look at that - he grabbed hold of my hand, didn't even make me bleed! | 0:05:00 | 0:05:04 | |
'So, if you get giant skinks in your back yard, | 0:05:07 | 0:05:09 | |
'what's lurking in the local park? | 0:05:09 | 0:05:12 | |
'I'm hoping for tiger snakes!' | 0:05:12 | 0:05:14 | |
Despite the fact that we are so close to all these houses, | 0:05:16 | 0:05:19 | |
this really is fantastic habitat for tiger snakes, | 0:05:19 | 0:05:22 | |
mostly because there's so much water, so many reeds, long grasses, | 0:05:22 | 0:05:26 | |
and that's perfect habitat for their main prey source, which is frogs. | 0:05:26 | 0:05:30 | |
If you're a snake and these super-fast frogs are on the menu, | 0:05:30 | 0:05:33 | |
then you want to be able to kill them quickly | 0:05:33 | 0:05:35 | |
so they don't hop away and leave you hungry. | 0:05:35 | 0:05:38 | |
That's exactly why the tiger snake's venom is SO strong | 0:05:38 | 0:05:41 | |
and fast-acting. | 0:05:41 | 0:05:43 | |
One bite and it's game over. | 0:05:43 | 0:05:45 | |
It's one thing to stop a frog dead in its tracks, | 0:05:47 | 0:05:50 | |
but here's the scary thing - | 0:05:50 | 0:05:51 | |
there's enough lethal venom in one bite from a tiger snake | 0:05:51 | 0:05:54 | |
to kill a handful of people. | 0:05:54 | 0:05:57 | |
Imagine you tread on one and it bites you. | 0:05:57 | 0:05:59 | |
The bite itself wouldn't feel that bad, | 0:05:59 | 0:06:03 | |
but inside your body, it's a very different story. | 0:06:03 | 0:06:06 | |
At first, your nerves stop firing | 0:06:06 | 0:06:09 | |
and you feel a tingling in your hands and feet, | 0:06:09 | 0:06:11 | |
then your muscles stop functioning properly, | 0:06:11 | 0:06:14 | |
you can't keep your eyes open and your throat starts to close. | 0:06:14 | 0:06:18 | |
Paralysis sets in. | 0:06:18 | 0:06:19 | |
Other toxins in the venom dissolve and eat your muscles. | 0:06:19 | 0:06:22 | |
It gets harder to move. | 0:06:22 | 0:06:24 | |
Meanwhile, your blood is being thickened into sticky clumps, | 0:06:24 | 0:06:28 | |
and as all the effects of the toxin combine, the organs start failing. | 0:06:28 | 0:06:32 | |
The muscles round your lungs seize up and you stop breathing. | 0:06:32 | 0:06:36 | |
If you don't get help in the form of anti-venom, | 0:06:36 | 0:06:39 | |
it could all be over within an hour. | 0:06:39 | 0:06:40 | |
You might think we're crazy to go looking for tiger snakes. | 0:06:40 | 0:06:44 | |
But both Mitch and I have been working with snakes for years. | 0:06:44 | 0:06:47 | |
We're all rooting for you! | 0:06:47 | 0:06:49 | |
-Yeah, yeah! -This way, mate. | 0:06:49 | 0:06:51 | |
STEVE SIGHS | 0:06:51 | 0:06:55 | |
Follow me, mate, you're more likely to catch something. | 0:06:55 | 0:06:58 | |
Get stuffed! | 0:06:58 | 0:06:59 | |
That's a good patch. | 0:06:59 | 0:07:01 | |
These basking platforms, they're perfect, | 0:07:01 | 0:07:03 | |
-cos they'll sit on there... -Good! | 0:07:03 | 0:07:05 | |
Oh, yeah, trying to get in front! I can run too! | 0:07:05 | 0:07:10 | |
Normally, I'd be going really slowly, really gently, | 0:07:11 | 0:07:15 | |
but because I'm all competitive, I'm half-running along! | 0:07:15 | 0:07:18 | |
To be honest, it's the best way, | 0:07:18 | 0:07:21 | |
because, really, the longer we take to come on top of them, | 0:07:21 | 0:07:24 | |
-the more chance they've got of getting away. -Yeah. | 0:07:24 | 0:07:26 | |
They are quite sensitive to disturbance, | 0:07:26 | 0:07:29 | |
so I've found, when I was doing research, | 0:07:29 | 0:07:33 | |
that walking at a good pace, | 0:07:33 | 0:07:34 | |
you know, all you're basically looking out for | 0:07:34 | 0:07:37 | |
is a black pile of shiny skin, so it's not like they're difficult, | 0:07:37 | 0:07:42 | |
and so you're better off just covering more ground. | 0:07:42 | 0:07:45 | |
Ah, got one! | 0:07:45 | 0:07:46 | |
'This method might look a bit gung-ho, | 0:07:46 | 0:07:48 | |
'but we're deadly serious. | 0:07:48 | 0:07:50 | |
'Using a snake hook like this keeps me at a safe distance | 0:07:50 | 0:07:53 | |
'and is also the gentlest way to handle the snake.' | 0:07:53 | 0:07:56 | |
It's all right, it's all right! | 0:07:56 | 0:07:58 | |
There's nothing worse than being patronised by an Australian! | 0:07:58 | 0:08:01 | |
THEY LAUGH | 0:08:01 | 0:08:03 | |
So... There's another one. | 0:08:03 | 0:08:05 | |
Yep, all right... That's... | 0:08:06 | 0:08:08 | |
-Get a hook... -Get out the way... | 0:08:08 | 0:08:09 | |
MITCH LAUGHS | 0:08:09 | 0:08:11 | |
I... | 0:08:13 | 0:08:14 | |
Didn't say a word, wasn't me! | 0:08:14 | 0:08:15 | |
Here's one. | 0:08:15 | 0:08:17 | |
Ah, this is just getting unfair. | 0:08:18 | 0:08:20 | |
See, the problem is, Steve, you SEE them, you gotta CATCH them. | 0:08:20 | 0:08:23 | |
I was waiting for Mark to go in and film it! | 0:08:23 | 0:08:25 | |
I was waiting for you to throw it at me! | 0:08:25 | 0:08:29 | |
There's one, right at the side here. | 0:08:29 | 0:08:31 | |
-Back off, back off! -Two, two, two! | 0:08:31 | 0:08:33 | |
There was two, that's why I couldn't grab it. There was two. | 0:08:33 | 0:08:36 | |
See that, basking together? | 0:08:36 | 0:08:38 | |
I just launched down, I thought, "There's too many coils there!" | 0:08:38 | 0:08:42 | |
Nearly had it! | 0:08:42 | 0:08:44 | |
This is a big one. It IS a big one. | 0:08:44 | 0:08:45 | |
And it's gone. | 0:08:47 | 0:08:48 | |
-Yep, there you go. -There's one. | 0:08:54 | 0:08:56 | |
All right, whip it out. | 0:08:56 | 0:08:57 | |
Go on, get it, get it, get it! | 0:08:59 | 0:09:00 | |
Gone. | 0:09:00 | 0:09:01 | |
Wahey! Good save! | 0:09:01 | 0:09:04 | |
I got it, I got it. | 0:09:04 | 0:09:06 | |
-Oh! Well done! -Finally! -OK... | 0:09:06 | 0:09:09 | |
We've been looking for... probably five minutes. | 0:09:09 | 0:09:13 | |
-Maybe two! -This is incredible! -Yeah! | 0:09:13 | 0:09:17 | |
We are right on the outskirts | 0:09:17 | 0:09:18 | |
of the biggest city in Western Australia | 0:09:18 | 0:09:21 | |
-and I have in my hand... -Watch it. | 0:09:21 | 0:09:24 | |
..the fourth most toxic venomous snake in the world - | 0:09:24 | 0:09:27 | |
the tiger snake. | 0:09:27 | 0:09:29 | |
-Mitch, this is an absolute beauty. -Yeah, it's cute. | 0:09:29 | 0:09:32 | |
Cute?! Only an Australian could describe a tiger snake as cute! | 0:09:32 | 0:09:37 | |
This is a snake | 0:09:37 | 0:09:39 | |
that needs to be treated with an amazing amount of respect | 0:09:39 | 0:09:42 | |
because drop by drop, | 0:09:42 | 0:09:43 | |
its venom is far more toxic than any of the cobras, | 0:09:43 | 0:09:47 | |
far more toxic than a king cobra, than a black mamba... | 0:09:47 | 0:09:50 | |
This has enough venom to bring down... | 0:09:50 | 0:09:52 | |
Mitch and I and probably the rest of the film crew as well. | 0:09:52 | 0:09:56 | |
But as you can see, | 0:09:56 | 0:09:58 | |
he has absolutely no interest in striking whatsoever. | 0:09:58 | 0:10:01 | |
What's wonderful about this | 0:10:01 | 0:10:03 | |
is that tiger snakes are in the same family as the cobras - | 0:10:03 | 0:10:06 | |
they're called elapids - | 0:10:06 | 0:10:08 | |
and you can actually see that it does have a hood. | 0:10:08 | 0:10:11 | |
It'll spread its body sideways, | 0:10:11 | 0:10:13 | |
making itself seem bigger that it actually is, | 0:10:13 | 0:10:16 | |
and standing a good portion of its body up off the ground as well. | 0:10:16 | 0:10:20 | |
-That is a classic cobra shape, isn't it? -Yeah. | 0:10:20 | 0:10:22 | |
For me, the reason the tiger snake is such an amazing predator | 0:10:22 | 0:10:28 | |
is just that it kills its prey so quickly, you know? | 0:10:28 | 0:10:31 | |
If you're feeding on a frog, | 0:10:31 | 0:10:33 | |
the last thing you want is to bite it, | 0:10:33 | 0:10:35 | |
for it to disappear into the reeds and you never find it again. | 0:10:35 | 0:10:38 | |
But if a tiger snake bites a frog, it's got minutes to live. | 0:10:38 | 0:10:41 | |
What you can see here... | 0:10:41 | 0:10:43 | |
Tiger snakes commonly have a reputation for charging people, | 0:10:43 | 0:10:48 | |
but you can see where that misconception comes from. | 0:10:48 | 0:10:51 | |
All this snake wants to do... is go straight back into the bush. | 0:10:51 | 0:10:56 | |
At the moment, he's heading straight for between my legs. | 0:10:56 | 0:10:59 | |
Just let him go. | 0:10:59 | 0:11:01 | |
This is the amount of confidence that I have... | 0:11:01 | 0:11:04 | |
..in this snake and its behaviour. | 0:11:07 | 0:11:09 | |
There's no way he was gonna bite me. | 0:11:09 | 0:11:11 | |
Heading off into the grass. | 0:11:11 | 0:11:13 | |
That is absolutely fantastic. | 0:11:13 | 0:11:15 | |
The thing that really gets me about this | 0:11:16 | 0:11:19 | |
is the fact that we've seen people wandering through here, | 0:11:19 | 0:11:23 | |
there's houses right there, but nobody here ever gets bitten. | 0:11:23 | 0:11:26 | |
In all the time I've been here, wandering around, like we're doing, | 0:11:26 | 0:11:30 | |
I'll actually have people pull over on their pushies, their push-bikes, | 0:11:30 | 0:11:34 | |
or stop while they're jogging in absolute disbelief, | 0:11:34 | 0:11:38 | |
and they say, "What are you doing?" | 0:11:38 | 0:11:40 | |
I say, "I'm studying tiger snakes." | 0:11:40 | 0:11:42 | |
They have no idea. | 0:11:42 | 0:11:44 | |
And the reason is, is because, this... I mean, | 0:11:44 | 0:11:48 | |
they're sitting along the edge in the vegetation, | 0:11:48 | 0:11:51 | |
minding their own business... | 0:11:51 | 0:11:52 | |
-The second anyone gets too close... -Yep, they disappear. | 0:11:52 | 0:11:55 | |
As soon as he knows he's safe, he'll pick up speed | 0:11:58 | 0:12:02 | |
and he'll shoot into that bush like nobody's business. | 0:12:02 | 0:12:05 | |
Look at that, wonderful. | 0:12:07 | 0:12:09 | |
Excellent! | 0:12:09 | 0:12:12 | |
I have never seen anywhere with so many venomous snakes | 0:12:12 | 0:12:15 | |
this close to so many people. | 0:12:15 | 0:12:17 | |
With one of the most potent venoms on the planet, | 0:12:19 | 0:12:21 | |
a tiger snake can kill its frog prey in minutes. | 0:12:21 | 0:12:24 | |
And that's why it's going on the Deadly 60. | 0:12:24 | 0:12:28 | |
Time to get wet and check out some deadly predators in the sea. | 0:12:35 | 0:12:39 | |
This may sound obvious, but if you're a predator, | 0:12:39 | 0:12:42 | |
the main benefit to living in the sea is fish. | 0:12:42 | 0:12:45 | |
Beneath me, there could be huge, shimmering shoals of fish, | 0:12:45 | 0:12:49 | |
packed full of protein. | 0:12:49 | 0:12:51 | |
My next contender to the Deadly 60 are all masters at catching fish, | 0:12:51 | 0:12:54 | |
but they all have very different ways of doing it. | 0:12:54 | 0:12:58 | |
Argh! | 0:12:58 | 0:12:59 | |
Woah-ha-ha! | 0:13:11 | 0:13:14 | |
Look at that! | 0:13:14 | 0:13:17 | |
As soon as they get in the water, they are transformed! | 0:13:17 | 0:13:20 | |
He turns from a sluggish big boulder on the beach into a torpedo! | 0:13:20 | 0:13:27 | |
Oh, you're just showing off now! | 0:13:40 | 0:13:43 | |
This might look like fun, | 0:13:43 | 0:13:45 | |
but try and imagine if you were a fish being hunted by this! | 0:13:45 | 0:13:48 | |
You wouldn't stand any chance at all. | 0:13:48 | 0:13:51 | |
Sea lions are formidable predators. | 0:13:51 | 0:13:54 | |
They are super-fast, reaching speeds of up to 40km an hour, | 0:13:54 | 0:13:58 | |
twisting and turning their whole bodies, | 0:13:58 | 0:14:01 | |
so they can even catch fish that are right behind them. | 0:14:01 | 0:14:04 | |
Check THAT out for deadly accuracy! | 0:14:04 | 0:14:07 | |
They have fantastic eyesight and ultra-sensitive whiskers | 0:14:09 | 0:14:13 | |
that can sense the tiniest of ripples made by fish. | 0:14:13 | 0:14:17 | |
All of these skills combine to make it a truly awesome predator. | 0:14:17 | 0:14:21 | |
Where are ya?! | 0:14:21 | 0:14:23 | |
He's behind me! | 0:14:26 | 0:14:28 | |
And he's underneath me! | 0:14:28 | 0:14:30 | |
There's another predator round here that has a very different strategy | 0:14:34 | 0:14:38 | |
for killing fish. | 0:14:38 | 0:14:40 | |
How am I supposed to get out of here?! | 0:14:40 | 0:14:42 | |
I'm not taking YOUR hand! | 0:14:42 | 0:14:44 | |
HE LAUGHS | 0:14:46 | 0:14:48 | |
-What you doing down there, Steve?! -STEVE LAUGHS | 0:14:50 | 0:14:53 | |
There are two birds here that would | 0:14:59 | 0:15:02 | |
definitely be in contention for the Deadly 60. | 0:15:02 | 0:15:04 | |
The first ones are these cormorants down the front here, | 0:15:04 | 0:15:07 | |
but I think the birds up the top definitely have the edge - | 0:15:07 | 0:15:11 | |
they're pelicans. | 0:15:11 | 0:15:12 | |
I'm sure there's a fair few of you at home who are thinking, | 0:15:16 | 0:15:20 | |
"Steve has finally lost it. | 0:15:20 | 0:15:22 | |
"Pelicans - they're rubbish, they're like big, oversized ducks." | 0:15:22 | 0:15:26 | |
If you're one of those thinking that, have a look at this. | 0:15:26 | 0:15:30 | |
Brown pelicans cruise effortlessly looking for their next meal. | 0:15:30 | 0:15:34 | |
Once they've spotted their prey, they fold up their wings | 0:15:34 | 0:15:37 | |
and accelerate to speeds of up to 65km an hour, | 0:15:37 | 0:15:40 | |
hitting the water like a javelin. | 0:15:40 | 0:15:44 | |
It's a regular pelican pile-up. | 0:15:49 | 0:15:51 | |
Although they hit the water fast, they stop quickly, | 0:15:51 | 0:15:56 | |
because their lightweight skeleton | 0:15:56 | 0:15:58 | |
is packed with air spaces that keeps them buoyant. | 0:15:58 | 0:16:01 | |
One of their most dramatic physical characteristics | 0:16:01 | 0:16:04 | |
is their unbelievable bill. It's the longest of any bird. | 0:16:04 | 0:16:08 | |
What's particularly extraordinary about it, | 0:16:25 | 0:16:28 | |
you think of pelicans as having huge swollen sacks under their bills, | 0:16:28 | 0:16:33 | |
but you can see at the moment, | 0:16:33 | 0:16:34 | |
it's lying right flush against the underside of the bill. | 0:16:34 | 0:16:38 | |
What's amazing is that when they hit the water, | 0:16:38 | 0:16:41 | |
they fill that sack with an enormous amount of water. | 0:16:41 | 0:16:44 | |
If you're wondering quite how much that is, | 0:16:51 | 0:16:53 | |
I'm gonna try and show you with the help of my glamorous assistant, | 0:16:53 | 0:16:57 | |
Rich the sound man. | 0:16:57 | 0:16:59 | |
Rich, if you could just hold this bag out like this... | 0:16:59 | 0:17:02 | |
So if you imagine this is the sack underneath the bill of the pelican. | 0:17:02 | 0:17:06 | |
This is water. | 0:17:08 | 0:17:10 | |
One litre... | 0:17:10 | 0:17:12 | |
Here we go... | 0:17:23 | 0:17:25 | |
13 litres of water! | 0:17:28 | 0:17:31 | |
HE LAUGHS | 0:17:31 | 0:17:33 | |
I can barely carry it! | 0:17:33 | 0:17:36 | |
Can you imagine that hanging underneath the beak?! | 0:17:36 | 0:17:39 | |
That's incredible! | 0:17:39 | 0:17:41 | |
Fortunately for the pelicans, they don't have to carry it around. | 0:17:43 | 0:17:47 | |
What they do is squeeze all the water out before eating the fish. | 0:17:47 | 0:17:51 | |
That can take about a minute, | 0:17:51 | 0:17:53 | |
and other birds keep trying to steal the fish left behind, | 0:17:53 | 0:17:56 | |
but finally, they do get to gulp it down. | 0:17:56 | 0:17:58 | |
Often, you'll see pelicans flying right over the surface of the water | 0:17:58 | 0:18:02 | |
and they can fly like that for a very long time. | 0:18:02 | 0:18:05 | |
It's not because they're too lazy to get up high and fly, | 0:18:05 | 0:18:08 | |
but because it's a very economical way of keeping in the air. | 0:18:08 | 0:18:11 | |
If you think of...waves... as being like this - | 0:18:11 | 0:18:17 | |
this is my rubbish drawing - | 0:18:17 | 0:18:19 | |
as wind blows along the surface of the wave, | 0:18:19 | 0:18:21 | |
it's driven up by the wave itself. | 0:18:21 | 0:18:24 | |
What this does is create lift, | 0:18:24 | 0:18:27 | |
so if a bird flies across here, it gets carried up by the wind. | 0:18:27 | 0:18:32 | |
You can see them almost cruising along with their wing tips | 0:18:32 | 0:18:36 | |
just grazing the top of the water, | 0:18:36 | 0:18:37 | |
and they can fly like that for miles, barely expending any effort. | 0:18:37 | 0:18:41 | |
I've got a little experiment to try and show you how this works. | 0:18:41 | 0:18:45 | |
Our researcher, John, is a dab hand... | 0:18:45 | 0:18:50 | |
with making paper aeroplanes. | 0:18:50 | 0:18:52 | |
I'm gonna see if this will lift up when it flies over the waves. | 0:18:52 | 0:18:57 | |
Don't worry, I AM gonna go and get it. | 0:18:57 | 0:19:00 | |
Here goes with a disastrous experiment... | 0:19:02 | 0:19:06 | |
If this works well, as this wave comes in, | 0:19:06 | 0:19:08 | |
it should lift the dart up. | 0:19:08 | 0:19:10 | |
HE LAUGHS | 0:19:10 | 0:19:14 | |
Rats! Got another dart, John?! | 0:19:14 | 0:19:17 | |
-HE LAUGHS -That was even worse! | 0:19:19 | 0:19:22 | |
You should write your name on it - whoever's flies best, wins! | 0:19:22 | 0:19:25 | |
It's the winner! | 0:19:28 | 0:19:29 | |
The crew has bombarded me with darts - one of them is gonna work! | 0:19:32 | 0:19:37 | |
Good luck, Steve! | 0:19:37 | 0:19:39 | |
Ooooh! | 0:19:41 | 0:19:42 | |
HE LAUGHS | 0:19:42 | 0:19:45 | |
No. | 0:19:46 | 0:19:47 | |
Sound man Richard's deadly 747. | 0:19:47 | 0:19:51 | |
Yeah! That is the winner! | 0:19:53 | 0:19:56 | |
That one went backwards! | 0:19:56 | 0:20:00 | |
We can fairly safely say my science experiment is rubbish, | 0:20:00 | 0:20:03 | |
but the pelicans do it a lot better. | 0:20:03 | 0:20:06 | |
Be under no illusions - | 0:20:13 | 0:20:15 | |
pelicans are killing machines. | 0:20:15 | 0:20:17 | |
They're large, fast and deadly accurate, | 0:20:17 | 0:20:22 | |
securing them a place on my Deadly 60. | 0:20:22 | 0:20:25 | |
Another day, another boat. | 0:20:38 | 0:20:40 | |
I'm on the trail of possibly the finest fish-finder in the seas. | 0:20:40 | 0:20:44 | |
It's an animal you're familiar with. | 0:20:44 | 0:20:46 | |
With its distinctive curved dorsal fin, | 0:20:46 | 0:20:48 | |
its sleek grey profile | 0:20:48 | 0:20:51 | |
and its brutally sharp teeth. | 0:20:51 | 0:20:53 | |
This could well be the most perfect predator in the Deadly 60. | 0:20:53 | 0:20:58 | |
But it's identity might come as a bit of a surprise. | 0:20:58 | 0:21:01 | |
I'll give you a clue - Sarah here is going to be my guide | 0:21:01 | 0:21:04 | |
and they call her the Dolphin Girl. | 0:21:04 | 0:21:08 | |
Literally, five minutes out of the dock and already | 0:21:08 | 0:21:12 | |
a whole bunch of bottlenose dolphins have popped up alongside. | 0:21:12 | 0:21:17 | |
There's about six or seven animals and they are so close. | 0:21:17 | 0:21:20 | |
These ones are right up at the bow. | 0:21:20 | 0:21:22 | |
This is a family group, known as a pod. | 0:21:22 | 0:21:25 | |
We're hoping that they want to stay and play. | 0:21:25 | 0:21:29 | |
So how come cute and cuddly dolphins | 0:21:29 | 0:21:32 | |
get to be contenders on my Deadly 60? | 0:21:32 | 0:21:35 | |
Well, just bear with me and I'll show you. | 0:21:35 | 0:21:38 | |
There are so many reasons why dolphins have to be on my Deadly 60. | 0:21:39 | 0:21:42 | |
First, their streamlined bodies and powerful tails | 0:21:42 | 0:21:45 | |
mean they're incredibly fast. | 0:21:45 | 0:21:47 | |
They can easily outstrip a boat like this | 0:21:47 | 0:21:49 | |
and they can jump 16 feet out of the water. | 0:21:49 | 0:21:53 | |
That's as high as our sound man's boom pole. | 0:21:53 | 0:21:58 | |
But the thing that really sets them apart | 0:22:06 | 0:22:08 | |
is that dolphins are incredibly brainy. | 0:22:08 | 0:22:11 | |
Look at this. | 0:22:11 | 0:22:13 | |
If you can imagine, this green jelly here is about the size | 0:22:13 | 0:22:18 | |
and the weight of a human brain | 0:22:18 | 0:22:20 | |
and this pink one, | 0:22:20 | 0:22:23 | |
which has kind of fallen apart | 0:22:23 | 0:22:25 | |
rather drastically | 0:22:25 | 0:22:27 | |
is a bit of an embarrassment, really. | 0:22:27 | 0:22:29 | |
But that's about the size of a dolphin brain. | 0:22:29 | 0:22:32 | |
Having a brain that big, being that intelligent | 0:22:32 | 0:22:35 | |
means that dolphins can work together in teams, | 0:22:35 | 0:22:37 | |
and come up with all kinds of different strategies | 0:22:37 | 0:22:40 | |
for catching fish. | 0:22:40 | 0:22:42 | |
Mmm. | 0:22:45 | 0:22:46 | |
Brains taste good. | 0:22:46 | 0:22:49 | |
Using that superior brain power to work together as a team | 0:22:50 | 0:22:54 | |
means they can come up with astonishing strategies | 0:22:54 | 0:22:57 | |
for catching fish. | 0:22:57 | 0:22:59 | |
Check out these dolphins in Florida. | 0:22:59 | 0:23:02 | |
That ring of muddy water was actually made by a dolphin | 0:23:02 | 0:23:05 | |
swimming along the bottom | 0:23:05 | 0:23:07 | |
to churn up the mud with its tail. | 0:23:07 | 0:23:09 | |
The ring encircles a shoal of fish, | 0:23:09 | 0:23:11 | |
the fish think they're trapped, and as they leap out to escape, | 0:23:11 | 0:23:15 | |
the other dolphins are lying in wait. | 0:23:15 | 0:23:17 | |
But the really amazing thing | 0:23:22 | 0:23:25 | |
is they all take turns to churn up the mud | 0:23:25 | 0:23:27 | |
so everyone gets a chance to grab a fish dinner | 0:23:27 | 0:23:30 | |
and have a bit of fun as well. | 0:23:30 | 0:23:33 | |
These dolphins have come up with a completely different technique. | 0:23:40 | 0:23:44 | |
They're not rushing up to the beach for a bit of fun. | 0:23:46 | 0:23:49 | |
They're herding fish out of the water so they're easier to catch | 0:23:49 | 0:23:52 | |
and that means stranding themselves, | 0:23:52 | 0:23:55 | |
which is a very risky thing for a dolphin to do, | 0:23:55 | 0:23:58 | |
but they choose beaches with just the right slope | 0:23:58 | 0:24:01 | |
so they can roll back safely after grabbing the fish. | 0:24:01 | 0:24:04 | |
Getting this right | 0:24:04 | 0:24:06 | |
takes not only intelligence but agility as well. | 0:24:06 | 0:24:10 | |
Finally, as well as chatting with their whistles and clicks, | 0:24:17 | 0:24:20 | |
dolphins use sound to find and catch their prey. | 0:24:20 | 0:24:24 | |
Bursts of ultrasound echo off anything solid in the water, | 0:24:24 | 0:24:28 | |
giving the dolphins a kind of sound picture | 0:24:28 | 0:24:31 | |
which they can even beam to each other, | 0:24:31 | 0:24:34 | |
a bit like e-mailing a photo, | 0:24:34 | 0:24:36 | |
but better. | 0:24:36 | 0:24:37 | |
Their ultrasound even penetrates the sand, | 0:24:37 | 0:24:40 | |
so there's nowhere to hide, | 0:24:40 | 0:24:42 | |
but in order to really see them properly, | 0:24:42 | 0:24:45 | |
I have to join them in their world. | 0:24:45 | 0:24:47 | |
I tell you what, I absolutely hate my job. | 0:24:48 | 0:24:51 | |
OK. Wish me luck, guys. | 0:24:59 | 0:25:01 | |
Good luck, Steve. | 0:25:01 | 0:25:03 | |
Get ready. | 0:25:03 | 0:25:04 | |
OK, guys, go! | 0:25:04 | 0:25:06 | |
These motorised sleds actually give you an idea | 0:25:10 | 0:25:13 | |
of what it's like to be a dolphin | 0:25:13 | 0:25:15 | |
and help us keep up with these beautiful streamlined animals. | 0:25:15 | 0:25:18 | |
It's frustrating, because we can't hold our breath | 0:25:18 | 0:25:21 | |
anywhere near as long as a dolphin, we need to keep coming up for air. | 0:25:21 | 0:25:25 | |
They also seem to be having as much fun as we are | 0:25:25 | 0:25:28 | |
and this is even more special because these are | 0:25:28 | 0:25:31 | |
really wild dolphins, and they're choosing to play with us. | 0:25:31 | 0:25:34 | |
This is out of this world! | 0:25:34 | 0:25:37 | |
I've never seen anything like it before in my life. | 0:25:37 | 0:25:41 | |
Just incredible. | 0:25:41 | 0:25:43 | |
Ah! That was out of this world! | 0:26:37 | 0:26:40 | |
And that's why dolphins are pretty much everyone's favourite animal. | 0:26:40 | 0:26:44 | |
But they're also fearsome hunters. | 0:26:44 | 0:26:47 | |
And that's why they're going on my Deadly 60. | 0:26:47 | 0:26:50 | |
Ultra-intelligent and adaptable, | 0:26:57 | 0:26:58 | |
perfectly streamlined and turbo-charged, | 0:26:58 | 0:27:01 | |
with built-in ultrasound and weapons systems, | 0:27:01 | 0:27:04 | |
dolphins have to be on my Deadly 60. | 0:27:04 | 0:27:07 | |
All in the name of science. Ow! That stung right through the suit. | 0:27:10 | 0:27:13 | |
Join me next time | 0:27:13 | 0:27:15 | |
as I continue my search for the Deadly 60. | 0:27:15 | 0:27:18 | |
Oh-ho! Getting up some speed now! | 0:27:20 | 0:27:23 | |
Sunlight here. | 0:27:23 | 0:27:25 | |
