0:00:02 > 0:00:04My name's Steve Backshall...
0:00:04 > 0:00:05Whoo!
0:00:05 > 0:00:07..and this is my search
0:00:07 > 0:00:10for the Deadly 60.
0:00:10 > 0:00:12That's not just animals that are deadly to me,
0:00:12 > 0:00:15but animals that are deadly in their own world.
0:00:17 > 0:00:19'My crew and I are travelling the planet.'
0:00:19 > 0:00:21And you're coming with me!
0:00:21 > 0:00:22Every step of the way.
0:00:27 > 0:00:30WHISPER: Deadly!
0:00:30 > 0:00:32This time on Deadly 60, we're in the Florida Keys
0:00:32 > 0:00:34and we'll take you back through time.
0:00:34 > 0:00:37Well, back through the last three series of Deadly 60, anyway.
0:00:37 > 0:00:39We'll show you a whole bunch of stuff
0:00:39 > 0:00:40that's never been seen before,
0:00:40 > 0:00:44some outtakes that I'd rather were never seen by anyone, ever,
0:00:44 > 0:00:48and we're also going to be getting in with these ravenous fish.
0:00:49 > 0:00:51Quite big, aren't they?
0:00:53 > 0:00:55Here we go!
0:00:55 > 0:00:58'Over the past four years we've circumnavigated the globe
0:00:58 > 0:01:01'in search of the finest wildlife wonders.
0:01:01 > 0:01:04'We've filmed in the frozen wilderness,
0:01:04 > 0:01:08'scorching deserts and just about everywhere in between,
0:01:08 > 0:01:12'capturing thousands of spectacular predators on camera.
0:01:12 > 0:01:14'But we always film more than we can fit on screen.'
0:01:14 > 0:01:16Whoa!
0:01:16 > 0:01:18'We can't squeeze it all in,
0:01:18 > 0:01:21'so this is our chance to show you a few of those forgotten gems.
0:01:21 > 0:01:24'This is Deadly Unseen.
0:01:27 > 0:01:30'Probably the finest Deadly destination is Latin America,
0:01:30 > 0:01:33'and a real highlight country was Venezuela,
0:01:33 > 0:01:38'with coastlines and caves, swampland and forests.'
0:01:38 > 0:01:40Whoa, that's fantastic!
0:01:40 > 0:01:42'One of the creepiest encounters we filmed
0:01:42 > 0:01:47'never made it on screen - until now.
0:01:47 > 0:01:51'A tangle with the largest venomous centipede on the planet.'
0:01:51 > 0:01:54We've just had a spot of real Deadly 60 luck.
0:01:54 > 0:01:58We've just been told that some locals have actually found
0:01:58 > 0:02:01a giant scolopendra in their back garden.
0:02:01 > 0:02:02I'm going to have a look now.
0:02:02 > 0:02:04Hola. Como estas?
0:02:04 > 0:02:07- Puero bella. - HE REPLIES IN SPANISH
0:02:07 > 0:02:08Si.
0:02:11 > 0:02:12No way!
0:02:12 > 0:02:16No way, that's enormous!
0:02:16 > 0:02:18Muchas gracias!
0:02:18 > 0:02:21OK, I'd rather take this away from his family before I take it out,
0:02:21 > 0:02:25because this is an animal that certainly could do a child
0:02:25 > 0:02:28an enormous amount of damage.
0:02:28 > 0:02:32So, just take it away from the house a little bit.
0:02:32 > 0:02:35I have to admit I'm a little bit shaky about this.
0:02:35 > 0:02:38I've handled scolopendra many, many times in the past,
0:02:38 > 0:02:42but nothing of this kind of size.
0:02:42 > 0:02:46This is absolutely formidable.
0:02:46 > 0:02:49Look at the size of it.
0:02:49 > 0:02:52That is just extraordinary.
0:02:52 > 0:02:58It's incredibly strong, harder to handle certainly than any snake.
0:02:58 > 0:03:01Look at that, look at the strength of it!
0:03:01 > 0:03:05It's actually just sunk its claws right into the thumb of the glove,
0:03:05 > 0:03:09and I'm very, very glad that these are really... Look at that!
0:03:09 > 0:03:12It's almost puncturing the leather.
0:03:13 > 0:03:17In fact, I'm not entirely sure that these gloves are strong enough!
0:03:17 > 0:03:19Whoa!
0:03:19 > 0:03:23That is a true living monster.
0:03:23 > 0:03:26So this is scolopendra gigantea,
0:03:26 > 0:03:29the largest species of centipede found on Earth.
0:03:29 > 0:03:31Whoo-er!
0:03:31 > 0:03:34It can get to be nearly 30 centimetres in length,
0:03:34 > 0:03:37which is as long as my forearm.
0:03:37 > 0:03:42And at the front of the head you can see those curved claws,
0:03:42 > 0:03:46they're actually adapted legs, but they're linked to a venom gland,
0:03:46 > 0:03:50which means that they can inject an absolutely ferocious toxin
0:03:50 > 0:03:53and overpower even quite decent-sized mammals.
0:03:53 > 0:03:57Look at the breadth of the body on this thing!
0:03:57 > 0:04:00It's absolutely phenomenal!
0:04:00 > 0:04:03I'm actually having to cling on with quite a lot of force
0:04:03 > 0:04:06because if I didn't, well, it would be off.
0:04:06 > 0:04:10There is no doubt that if this actually got to exposed skin,
0:04:10 > 0:04:14it would definitely bite, and if it did, it probably wouldn't kill me,
0:04:14 > 0:04:16but I really don't want to take that chance.
0:04:18 > 0:04:21Wow!
0:04:21 > 0:04:23You horrible thing!
0:04:23 > 0:04:25You're horrible! I hate you!
0:04:25 > 0:04:29Can I put it back in the bucket now, please?
0:04:33 > 0:04:35Wugh-ha-ha-ha-ha!
0:04:35 > 0:04:38Oh! Holy Moley!
0:04:41 > 0:04:43'The crew admitted later,
0:04:43 > 0:04:46'they'd been holding their breath in horror the entire time.
0:04:50 > 0:04:53'If that gave you the creeps, bear with us,
0:04:53 > 0:04:56'cos the next charmer really has the furry factor.
0:04:56 > 0:04:59'Whilst in New Zealand filming sperm whales,
0:04:59 > 0:05:03'we met a colony of marine mammals that were about as cute and cuddly
0:05:03 > 0:05:05'as Deadly 60 ever gets.'
0:05:05 > 0:05:10Surrounding me now are New Zealand fur seals.
0:05:10 > 0:05:14In fact, there's one quite large male here,
0:05:14 > 0:05:17who's taken an active interest in us.
0:05:17 > 0:05:18You can instantly tell
0:05:18 > 0:05:20the difference between the boys and the girls.
0:05:20 > 0:05:23The males are so much bigger, so much bulkier.
0:05:23 > 0:05:28And the reason for that is not in any way to help them with hunting
0:05:28 > 0:05:30and it's not to get rid of predators.
0:05:30 > 0:05:32In fact, it's for fighting with other males.
0:05:33 > 0:05:38Confrontations between adult seals can be brutal.
0:05:43 > 0:05:45The males have just one thing on their minds
0:05:45 > 0:05:49and that's to gather as many females as possible
0:05:49 > 0:05:51in what's known as a hareem.
0:05:51 > 0:05:57From an early age, they face-off in ferocious fights with real bite.
0:06:04 > 0:06:08This guy here is bearing a fair few battle scars,
0:06:08 > 0:06:10where he's fought with other males.
0:06:10 > 0:06:12'The wounds are worth it
0:06:12 > 0:06:14'for the right to breed with the females
0:06:14 > 0:06:17'and pass on his genes to the next generation.'
0:06:17 > 0:06:21The young pups are impossibly inquisitive.
0:06:21 > 0:06:24This one here's just made his way all the way up from the water line
0:06:24 > 0:06:26to come and find out what we are.
0:06:26 > 0:06:29It seems ridiculous to be thinking about putting
0:06:29 > 0:06:32something so impossibly cute on the Deadly 60.
0:06:32 > 0:06:34But seeing the animal up this close,
0:06:34 > 0:06:40you can see a few of the features that make it a hunting machine.
0:06:40 > 0:06:42Those great big, dark, soulful eyes
0:06:42 > 0:06:46are very, very good at seeing fish in murky waters,
0:06:46 > 0:06:50but even when the water's too murky to be able to see the fish,
0:06:50 > 0:06:54it can sense them with these, the brisi, or whiskers,
0:06:54 > 0:07:00and right now, I think he wants to sense Graham the cameraman!
0:07:00 > 0:07:02I think he likes you, Gray!
0:07:03 > 0:07:06How cute is that?
0:07:06 > 0:07:11'Despite their pin-up pup good looks, when they grow into adults
0:07:11 > 0:07:14'these seals are not to be messed with.
0:07:14 > 0:07:17'And some of the macho males have decided
0:07:17 > 0:07:20'we've been on their turf a bit too long.'
0:07:20 > 0:07:25I'll tell you what, quite threatening, aren't they?
0:07:25 > 0:07:27We're actually hemmed in now,
0:07:27 > 0:07:29so I think it's maybe best that we move back.
0:07:34 > 0:07:37OK, it's all right, I'm going, I'm going.
0:07:40 > 0:07:44Wherever seals live, they need to be tough to survive
0:07:44 > 0:07:48and especially in the waters off South Africa.
0:07:48 > 0:07:51'Earlier in the series, we brought you some stunning images
0:07:51 > 0:07:53'of Cape fur seals under attack
0:07:53 > 0:07:55'from one of the world's most feared predators,
0:07:55 > 0:07:56'the great white shark.'
0:07:56 > 0:07:58Johnny, Johnny, Johnny!
0:07:59 > 0:08:01Real predation going on!
0:08:01 > 0:08:04Oh, it's a biggy, it's a biggy!
0:08:04 > 0:08:05Holy Moley!
0:08:05 > 0:08:08Let's get up the front of the boat, front of the boat!
0:08:10 > 0:08:15Directly off... Oh, this is huge! Absolutely huge!
0:08:15 > 0:08:16This is unbelievable!
0:08:18 > 0:08:20The shark is coming fully out of the water.
0:08:20 > 0:08:23This is one of the most extraordinary things I've seen,
0:08:23 > 0:08:25I never thought for a second we'd actually see
0:08:25 > 0:08:28a shark genuinely hunting a seal.
0:08:29 > 0:08:30Oh!
0:08:30 > 0:08:33The tail of the shark is just lashing around,
0:08:33 > 0:08:36you can see the dorsal fin and the tail breaking the surface
0:08:36 > 0:08:39and you can just see the seal leaping out of the water,
0:08:39 > 0:08:41porpoising, trying to get away from the shark.
0:08:41 > 0:08:44This tiny little seal is just battling for survival,
0:08:44 > 0:08:48it's leaping clear out of the water, trying to evade the shark.
0:08:51 > 0:08:52No way!
0:08:52 > 0:08:55'But these dramatic scenes were only half the story.
0:08:57 > 0:09:00'One remarkable unseen moment brought us closer
0:09:00 > 0:09:03'to the age-old struggle between shark and seal,
0:09:03 > 0:09:06'than we ever expected. After taking a hit from a great white,
0:09:06 > 0:09:10'one small wounded seal pup took refuge
0:09:10 > 0:09:13'in the only safe place he could find - our shark cage.'
0:09:13 > 0:09:18This little seal here is exactly the size of the animals
0:09:18 > 0:09:20that are being hunted by the great white sharks.
0:09:20 > 0:09:23It's just old enough to have become independent,
0:09:23 > 0:09:25to go out and start hunting for itself.
0:09:25 > 0:09:27It's incredibly vulnerable out here.
0:09:27 > 0:09:30If you look at the rear flipper
0:09:30 > 0:09:33you can see the teeth marks of a shark attack.
0:09:34 > 0:09:37Look at that.
0:09:37 > 0:09:39Look you can see where the teeth
0:09:39 > 0:09:44have sliced right through the outside skin.
0:09:44 > 0:09:48And this beautiful creature is just taking refuge here,
0:09:48 > 0:09:52because it knows that, out there, he's going to get hammered.
0:09:52 > 0:09:55And there's a shark up behind the boat.
0:09:57 > 0:09:58He looks really tired.
0:10:01 > 0:10:06Because he's a mammal and he's got those big, dark, soulful eyes -
0:10:06 > 0:10:08they're more closely related to us -
0:10:08 > 0:10:11it's very hard not to feel your heartstrings being tugged.
0:10:11 > 0:10:13You feel like you should come down on the side of the seal,
0:10:13 > 0:10:16but this is just nature.
0:10:16 > 0:10:19This is the battle between the predators and the smaller predators.
0:10:22 > 0:10:24'It would have been just plain cruel
0:10:24 > 0:10:28'to usher this pup out with sharks circling, scenting blood.
0:10:28 > 0:10:31'But great whites won't swim into the beds of giant kelp seaweed
0:10:31 > 0:10:33'that border the seal colony.
0:10:33 > 0:10:36'If we could get the pup close, he should have a fighting chance.'
0:10:38 > 0:10:41We're just backing up the boat, so that it's closer to the kelp
0:10:41 > 0:10:44and closer to the rocky islands where the seal will be safe.
0:10:44 > 0:10:48Hopefully, it'll make a beeline out of the cage
0:10:48 > 0:10:51and, yeah, away from the sharks.
0:10:51 > 0:10:53Ah, there he goes, there he goes!
0:10:53 > 0:10:55Yes!
0:10:55 > 0:10:58Oh, fantastic.
0:10:58 > 0:11:01We're right by the kelp now and he's going to be safe.
0:11:02 > 0:11:04Wow.
0:11:04 > 0:11:06That was all a bit crazy for a while there.
0:11:06 > 0:11:09'The pup lives to fight another day -
0:11:09 > 0:11:13'traumatised, tender, but hopefully, a whole lot wiser.
0:11:13 > 0:11:16'That a tiny seal could cheat the mightiest
0:11:16 > 0:11:21'set of jaws on Earth is one of the great escape feats on the planet.
0:11:21 > 0:11:25'This titanic battle plays out daily on these southern seas,
0:11:25 > 0:11:28'and I got to see it first-hand.'
0:11:31 > 0:11:33Ohhh!
0:11:34 > 0:11:37'The shark's breathtaking breach attack is so dynamic
0:11:37 > 0:11:40'that even a one-tonne shark
0:11:40 > 0:11:43'follows through into open air above the waves.
0:11:43 > 0:11:46'Imagine the force that must be behind that strike.
0:11:46 > 0:11:51'Any seal that can evade a great white is worthy of huge respect.'
0:11:54 > 0:11:57'We always aim to bring a new angle
0:11:57 > 0:11:59'to the animals we add to the Deadly 60,
0:11:59 > 0:12:03'and with the help of a special camera, that's what we did
0:12:03 > 0:12:06'during this unseen night-time outing in the Komodo National Park.'
0:12:09 > 0:12:15I've got here a thermal imaging camera, which picks up the heat
0:12:15 > 0:12:19from the moving bodies of animals, particularly warm-blooded animals.
0:12:19 > 0:12:24I can see that there's a couple of Timor deer feeding ahead of me.
0:12:24 > 0:12:29Just see their white forms from the heat being given off
0:12:29 > 0:12:33by their bodies. What else have we got out there?
0:12:33 > 0:12:37'How's about a heat-seeking shot of Komodo's most famous animal?'
0:12:37 > 0:12:39Wow.
0:12:39 > 0:12:43OK, so I'm actually looking at a Komodo dragon.
0:12:43 > 0:12:45Looking at these pictures,
0:12:45 > 0:12:49the things that are showing up as blue or green, those are very cool.
0:12:49 > 0:12:52Things that are yellow or red, they're quite warm,
0:12:52 > 0:12:56and things that are white, they're actually very hot.
0:12:56 > 0:12:58What's interesting is that these animals
0:12:58 > 0:13:00are thought of as being cold-blooded,
0:13:00 > 0:13:05but you can see the tongue is coming out as white, the belly is white,
0:13:05 > 0:13:07which means it's very hot.
0:13:07 > 0:13:10Even the skin is coming up much hotter
0:13:10 > 0:13:12than the surrounding environment.
0:13:12 > 0:13:16And the reason is that cold-blooded,
0:13:16 > 0:13:19well, it's not a very apt name, really.
0:13:19 > 0:13:23Actually reptiles can have blood that's much warmer than our own.
0:13:23 > 0:13:30So during the daytime, he'll absorb as much heat as he can
0:13:30 > 0:13:32from the surrounding environment
0:13:32 > 0:13:35and he can keep that warmth and use it for energy.
0:13:35 > 0:13:38Mind you, come back in the morning after a cool night,
0:13:38 > 0:13:40and it'd be a very different story.
0:13:42 > 0:13:44That's really cool.
0:13:47 > 0:13:50'Perhaps the most adrenaline-charged encounter of all
0:13:50 > 0:13:53'was in search of the largest reptile on Earth.
0:13:55 > 0:13:57'In the Northern Territories of Australia,
0:13:57 > 0:14:00'I was lowered into a croc's nest by helicopter.'
0:14:00 > 0:14:02I can see the nest.
0:14:02 > 0:14:03Whoa!
0:14:05 > 0:14:11'We scientifically measured the most formidable bite force on Earth.'
0:14:11 > 0:14:15Good Lord, the power of the animal is phenomenal.
0:14:15 > 0:14:20'In fact, we had so much croc action that we didn't get a chance
0:14:20 > 0:14:24'to show you another of the salties' sublime skills.
0:14:24 > 0:14:29'For now, they're lurking invisible, but even a monster croc can leap.'
0:14:31 > 0:14:34There, Gray, crocodile.
0:14:34 > 0:14:36Do you see it?
0:14:40 > 0:14:42'This river has one of the highest concentrations
0:14:42 > 0:14:44'of salties in the world.'
0:14:46 > 0:14:48'They know that food's on offer.'
0:15:04 > 0:15:06That is just incredible.
0:15:16 > 0:15:22The most extraordinary noise when those jaws just clatter shut.
0:15:22 > 0:15:26It has such a heavy, bony skull and a fantastically-powerful bite
0:15:26 > 0:15:30and that sound - just formidable.
0:15:34 > 0:15:39'Saltwater crocs can be territorial and fight rivals for access to food.
0:15:39 > 0:15:42'But we weren't expecting them to do it right in front of us.'
0:15:55 > 0:15:59EXCITED CHATTER
0:15:59 > 0:16:01Well, there you go.
0:16:01 > 0:16:05That's pretty good evidence of quite how fearsome this animal is.
0:16:05 > 0:16:08Two big males just had a complete fit over each other
0:16:08 > 0:16:13and this one here never even saw it coming.
0:16:13 > 0:16:17'Our bait is just an appetiser for these mammoth reptiles.
0:16:17 > 0:16:19'A fully-grown adult can consume
0:16:19 > 0:16:22'something as large as a water buffalo,
0:16:22 > 0:16:25'but they'll make do with much smaller morsels,
0:16:25 > 0:16:26'if that's all that's on offer.'
0:16:32 > 0:16:36This leaping might seem like unnatural behaviour,
0:16:36 > 0:16:39but they have been seen leaping clear out of the water
0:16:39 > 0:16:43to snatch bats, as they roost at the waterside.
0:16:44 > 0:16:47The way they do it is with that flat paddle-shaped tail,
0:16:47 > 0:16:50large muscles behind the leg at the base of the tail,
0:16:50 > 0:16:53which allow them to generate enormous dynamic forces,
0:16:53 > 0:16:56driving themselves right up out of the water.
0:16:57 > 0:17:00It's such an impressive animal.
0:17:04 > 0:17:08'One group of animals featured more on the Deadly 60 than any other
0:17:08 > 0:17:10'is the snakes.
0:17:10 > 0:17:13'I have a soft spot for these reptilian delights.
0:17:13 > 0:17:16'Any snake day is a good day by me.
0:17:16 > 0:17:19'We've showed you hundreds of species of snake,
0:17:19 > 0:17:23'but somehow this encounter in Argentina slipped through the net.'
0:17:23 > 0:17:24Stop! Stop, stop, stop.
0:17:28 > 0:17:30Not sure.
0:17:31 > 0:17:32Snake. Oh, yes.
0:17:35 > 0:17:40It's just come off the road, into this bush here.
0:17:40 > 0:17:43Oh, wow, it's a beauty. Can you see that?
0:17:43 > 0:17:46Right, this is a really good find.
0:17:46 > 0:17:49It's a lancehead, a highly-venomous snake
0:17:49 > 0:17:51and one of the most feared of this region.
0:17:51 > 0:17:54Let's just see if I can lift it out.
0:18:00 > 0:18:04Oh, look at that, vibrating of the tail on my hand.
0:18:04 > 0:18:07You see that?
0:18:07 > 0:18:11That's something this particular snake does to lure its rodent prey.
0:18:14 > 0:18:17Oh, it's beautiful!
0:18:17 > 0:18:22'Out here, so far from hospital, a bite would be a bad thing.'
0:18:23 > 0:18:31This is an absolutely wonderful snake. The crossed lancehead.
0:18:31 > 0:18:36Looking all the way down its back, its upper surface,
0:18:36 > 0:18:41you can see these perfect brown crosses with the white background.
0:18:41 > 0:18:43They're very, very beautiful.
0:18:43 > 0:18:49Very distinctive, but also a highly important part of its camouflage.
0:18:49 > 0:18:53This whole group of snakes is known as the lanceheads
0:18:53 > 0:18:56and that is because of the shape of the head.
0:18:56 > 0:19:00The head itself is shaped like an arrow or a spearhead.
0:19:00 > 0:19:03It's incredibly useful for throwing the head out at great speed
0:19:03 > 0:19:06when it's striking at its prey.
0:19:06 > 0:19:07Isn't he wonderful?
0:19:07 > 0:19:11The crossed lancehead mostly feeds on warm-blooded prey.
0:19:11 > 0:19:14Around here, that's going to be rats, mice, guinea pig.
0:19:14 > 0:19:18It can eat things that are much bigger than its own head.
0:19:18 > 0:19:21His venom is really quite fiery
0:19:21 > 0:19:25and I certainly wouldn't want to get bitten and, apart from that,
0:19:25 > 0:19:29I want to let him go about his business and go off and hunt.
0:19:32 > 0:19:37'I can't believe I didn't put that lethal lancehead on the list.
0:19:37 > 0:19:40'Just goes to show how strong the other contenders were.'
0:19:49 > 0:19:52'This series of Deadly introduced 60 more scintillating
0:19:52 > 0:19:53'ninjas of the natural world.'
0:19:56 > 0:19:57Wow!
0:19:57 > 0:19:59'But this is an unseen special.
0:19:59 > 0:20:03'So here's one more aquatic assassin haunting the Florida Keys.'
0:20:03 > 0:20:06These are tarpon.
0:20:06 > 0:20:10They're a predatory fish, very stout, thick bodied, fast,
0:20:10 > 0:20:12and they've also got quite sharp teeth.
0:20:15 > 0:20:17'They're impressive from the surface,
0:20:17 > 0:20:19'but in their world, it'll be even better.
0:20:19 > 0:20:23'While the crew keep their attention by feeding them from the jetty,
0:20:23 > 0:20:25'I'm going to slip in.'
0:20:26 > 0:20:29Here goes nothing!
0:20:33 > 0:20:37Oh-ho-ho! That is just brilliant!
0:20:37 > 0:20:40Almost a prehistoric mouth heading straight towards me,
0:20:40 > 0:20:43snatching the fish and then swimming away.
0:20:43 > 0:20:47You just get a flash of the silver side of the fish.
0:20:47 > 0:20:51'Tarpon can grow to over two metres long and weigh twice as much as me.
0:20:51 > 0:20:57'That is a big fish and the fish can accelerate surprisingly fast.
0:20:57 > 0:20:58'They use that turn of speed
0:20:58 > 0:21:03'and a decisive snap to monster down shrimp, crab and other fish.'
0:21:03 > 0:21:05Wow! That is brilliant!
0:21:08 > 0:21:10'The turn of pace of the tarpon,
0:21:10 > 0:21:14'another tantalising hunter I can't quite believe didn't make the list.'
0:21:17 > 0:21:20The Deadly 60 crew and I are true professionals.
0:21:20 > 0:21:24We've been doing this for many, many years and we never, ever
0:21:24 > 0:21:25make mistakes.
0:21:25 > 0:21:27Ever.
0:21:28 > 0:21:32Hello and welcome to Deadly 60.
0:21:32 > 0:21:36This time on Deadly 60, we're in the Philippines. Wah! Ha-ha!
0:21:36 > 0:21:41This time on Deadly 60, we're ooh! Ooh, ooh! Hoo-hoo!
0:21:41 > 0:21:44Am I supposed to be looking cool when doing this?
0:21:50 > 0:21:54But there are some deadly creatures...
0:21:54 > 0:21:57Even a huge croc can hide...
0:22:09 > 0:22:12That wasn't me. I didn't do that, nobody saw it.
0:22:13 > 0:22:16And to get close to them, I'm taking to the...
0:22:19 > 0:22:24..like paddles and it can. Argh! Who put that wall there?
0:22:24 > 0:22:26But our next step...
0:22:26 > 0:22:30THEY LAUGH
0:22:30 > 0:22:32Try that again, shall we?
0:22:32 > 0:22:34This is. Ooh! Crikey!
0:22:34 > 0:22:35Mwah!
0:22:35 > 0:22:37TINY BARK
0:22:37 > 0:22:40This is the high savanna of Nummibbia. Nnummbbbmmm!
0:22:40 > 0:22:42These are...
0:22:42 > 0:22:45..that's packed with muscle.
0:22:45 > 0:22:48This centipede in particular has much, much less than a...
0:22:48 > 0:22:51TONGUE TIED
0:22:52 > 0:22:55Deadly, debilly going on my deadliness.
0:22:55 > 0:22:57This place may not look the best place
0:22:57 > 0:23:00to look for wildlife, but as places go, it's a great place.
0:23:00 > 0:23:03It's called the giant scolopendra.
0:23:03 > 0:23:05It's the largest species of centipede
0:23:05 > 0:23:08and I've got myself trapped in a tree.
0:23:08 > 0:23:10SOUND OF BREAKING WIND
0:23:10 > 0:23:11Did you hear that?
0:23:11 > 0:23:14MORE BREAKING WIND
0:23:19 > 0:23:21Honestly, Nick!
0:23:21 > 0:23:23This is going to go on forever!
0:23:25 > 0:23:27Whoa!
0:23:27 > 0:23:30'So, we've shown you some memorable unseen moments.
0:23:30 > 0:23:34'Plus a few that I'd really rather forget!
0:23:34 > 0:23:37'But I'd like to finish with perhaps my most memorable Deadly encounter.'
0:23:39 > 0:23:42Oh, crikey! 'And there are a lot to choose from.
0:23:42 > 0:23:44'We've had close calls...'
0:23:44 > 0:23:48Apparently, there is a danger that they might leap out. Ohhh! Arrrgh!
0:23:51 > 0:23:54'..found rare and endangered species...'
0:23:54 > 0:23:56They are majestic animals.
0:23:56 > 0:23:57Stop, stop! There it is!
0:23:57 > 0:24:01'..and succeeded against all the odds.'
0:24:01 > 0:24:03I don't actually believe what I'm seeing.
0:24:03 > 0:24:07We have, at the side of the road, the most venomous snake on Earth.
0:24:07 > 0:24:10'I treasure each and every animal we film.
0:24:10 > 0:24:12'They're masters of their environment,
0:24:12 > 0:24:14'but some I will never forget.'
0:24:16 > 0:24:19'In series one, a great hammerhead shark shocked us all
0:24:19 > 0:24:22'when it swam out of the gloom.'
0:24:22 > 0:24:26Oh Simon, Simon! I do not believe it! That is out of this world!
0:24:28 > 0:24:32'And in series two, we saw orca hunting and playing.'
0:24:32 > 0:24:34Whoa!
0:24:34 > 0:24:35Oh, my goodness!
0:24:39 > 0:24:43'But on series three, one encounter really stood out -
0:24:43 > 0:24:46'a meeting with the animal record breaker.
0:24:46 > 0:24:48'It was hard work, against all the odds
0:24:48 > 0:24:50'and will always stay with me.'
0:24:50 > 0:24:53This is one of the biggest challenges we've ever taken on.
0:24:53 > 0:24:56We've got a small rib behind us, which is more manoeuvrable,
0:24:56 > 0:24:59which will make it easier to get into a good position
0:24:59 > 0:25:02and then Johnny the cameraman and I are just going to dive in
0:25:02 > 0:25:03and swim like crazy.
0:25:03 > 0:25:06But, if we pull it off, it'll be one of the greatest things
0:25:06 > 0:25:09we've ever done on Deadly 60.
0:25:09 > 0:25:12'We're about to try and swim with an animal I genuinely thought
0:25:12 > 0:25:15'I would never even see.
0:25:15 > 0:25:18'The largest creature that's ever known to have lived...'
0:25:18 > 0:25:21You see it? Johnny's got a vision on it.
0:25:21 > 0:25:23'..the blue whale.'
0:25:32 > 0:25:36'We're trying to keep up with an animal the size of a passenger jet.
0:25:36 > 0:25:40'I'm kicking as hard as I can. My heart is racing.'
0:25:53 > 0:25:55'The whales gather here off the coast of Sri Lanka
0:25:55 > 0:25:58'to feed on tiny crustaceans called krill,
0:25:58 > 0:26:01'gulping down up to four tonnes-worth every day.
0:26:03 > 0:26:06'Sadly, these gentle giants are endangered.
0:26:06 > 0:26:08'To share the sea with them
0:26:08 > 0:26:12'for precious seconds is one of the greatest moments of my life.'
0:26:16 > 0:26:19Vast blue shapes in the crystal clear water,
0:26:19 > 0:26:23they cruise by, barely seeming to move at all,
0:26:23 > 0:26:26but no Olympic swimmer could ever hope to keep pace.
0:26:29 > 0:26:31A truly humbling experience
0:26:31 > 0:26:35and my favourite Deadly encounter, so far.
0:26:37 > 0:26:39Whoo!
0:26:43 > 0:26:46That was like nothing I have ever seen before.
0:26:46 > 0:26:52Just a giant submarine cruising below us and totally at ease,
0:26:52 > 0:26:55didn't seem to care at all that we were there in its world.
0:26:55 > 0:27:01I have never felt so utterly dwarfed by a living creature in my life.
0:27:01 > 0:27:05The largest animal that has ever lived, the blue whale.
0:27:05 > 0:27:07Definitely on my list.
0:27:10 > 0:27:11Yes!!
0:27:14 > 0:27:17This is my search for the Deadly 60.
0:27:17 > 0:27:18'So far on Deadly 60,
0:27:18 > 0:27:23'we've been to 28 countries on six different continents.'
0:27:23 > 0:27:24No way!
0:27:24 > 0:27:28'We've filmed thousands of the world's deadliest animals.'
0:27:28 > 0:27:30Ooh. Argh. Oh, yeah!
0:27:30 > 0:27:33'But I reckon we haven't even scratched the surface.'
0:27:33 > 0:27:34Wow!
0:27:34 > 0:27:38'There's still an infinite amount of wild wonders out there.
0:27:38 > 0:27:42'Places to explore and adventures to be had.
0:27:44 > 0:27:47'This is just the beginning.'
0:27:47 > 0:27:50And you're coming with me every step of the way.
0:27:52 > 0:27:56They are absolutely extraordinary snakes.
0:27:56 > 0:27:58- Ah! - CREW:- He's lost his trunks!
0:27:58 > 0:27:59This is not good!
