0:00:02 > 0:00:04My name's Steve Backshall.
0:00:06 > 0:00:07You can call me Steve.
0:00:08 > 0:00:12I'm on a mission to find the Deadly 60 -
0:00:12 > 0:00:14that's 60 deadly creatures.
0:00:14 > 0:00:16I'm travelling all over the world...
0:00:16 > 0:00:20and you're coming with me every step of the way.
0:00:23 > 0:00:24Shark!
0:00:29 > 0:00:33This time on Deadly 60 we're with the sea gypsies of Borneo.
0:00:33 > 0:00:35It's here!
0:00:35 > 0:00:39Some of the happiest, smiliest, friendliest people on the planet.
0:00:39 > 0:00:42I have absolutely no idea what we're going to find on this programme.
0:00:42 > 0:00:45But trust me - we're going to get wet!
0:00:45 > 0:00:46Argh!
0:00:51 > 0:00:54The seas here are full of deadly animals.
0:00:54 > 0:00:57To find them, I've got to look in three main areas -
0:00:57 > 0:01:02the shallows near the beach, further out on the coral reef
0:01:02 > 0:01:05and further still, the open ocean.
0:01:06 > 0:01:09'The local sea gypsies spend their entire lives'
0:01:09 > 0:01:11living in boats on the water.
0:01:11 > 0:01:14To get an idea of what creatures I might find,
0:01:14 > 0:01:16I'm going to start with them.
0:01:21 > 0:01:23HE SPEAKS LOCAL DIALECT
0:01:26 > 0:01:31Ah, right. So I just asked how many people are living on board this boat.
0:01:31 > 0:01:35There's ten. Ten people who spend their whole lives
0:01:35 > 0:01:39on this one rather wonderful all-wooden boat.
0:01:42 > 0:01:44Obviously, when you spend your entire life at sea,
0:01:44 > 0:01:50the vast majority of food is going to be seafood.
0:01:50 > 0:01:53This is a bit of a selection of the things they've been catching.
0:01:53 > 0:01:56Look at that!
0:01:58 > 0:02:04THAT bizarre looking creature... is a slipper lobster.
0:02:04 > 0:02:06Wow.
0:02:12 > 0:02:15Let's see what other goodies they've got in here.
0:02:15 > 0:02:17Wow.
0:02:18 > 0:02:21'That tail slap can propel the lobster
0:02:21 > 0:02:24'through the water at a furious pace.
0:02:24 > 0:02:26'It's a great way to get away from predators.'
0:02:27 > 0:02:32Up on the roof, I'm going to see what Dad's preparing from the day's catch.
0:02:32 > 0:02:36Because they don't have any electricity, so no refrigeration,
0:02:36 > 0:02:39the best way of keeping fish so that it can still be eaten
0:02:39 > 0:02:40is to dry it in the sun.
0:02:40 > 0:02:43So this roof is covered with all different kinds of fish,
0:02:43 > 0:02:49but mostly these - blue-spotted stingrays.
0:02:49 > 0:02:52Seeing all of these creatures gives me a clue as to what's in the sea.
0:02:52 > 0:02:57'Time to splash down and find some contenders for my Deadly 60 list.'
0:02:57 > 0:03:00Obviously, it's far better to see animals
0:03:00 > 0:03:03when they're in their natural state and alive.
0:03:03 > 0:03:07We've got all of this high-tech kit to get us down there and keep
0:03:07 > 0:03:08us there as long as possible,
0:03:08 > 0:03:12all of this scuba equipment plus some amazing fancy looking cameras,
0:03:12 > 0:03:20and this, it's a special scuba mask which has a microphone inside,
0:03:20 > 0:03:22which means you can hear every single word
0:03:22 > 0:03:24I'm talking while I'm underwater.
0:03:25 > 0:03:30The first place I'm looking may seem a bit weird - it's an old oil rig.
0:03:30 > 0:03:35Why dive there? Well, it's famous locally for ambush predators.
0:03:35 > 0:03:39Those are deadly killers that all hunt in a similar way,
0:03:39 > 0:03:43using stealth and camouflage, so keep your eyes peeled.
0:03:47 > 0:03:53Diving with me are two cameramen, Simon and Chris.
0:03:53 > 0:03:56Keeping us safe are dive buddies, James...
0:03:56 > 0:03:57and Jimmy.
0:04:02 > 0:04:07Simon's first in. But it's not long until I can have a bit of a dip.
0:04:17 > 0:04:20This is the big blue.
0:04:21 > 0:04:24Absolutely dazzling.
0:04:37 > 0:04:38Wow!
0:04:41 > 0:04:43Huge piles of junk like this
0:04:43 > 0:04:48might look like a great big rubbish tip, but underwater,
0:04:48 > 0:04:53sometimes they can prove a great home for animals like this.
0:04:53 > 0:05:00This is one of the best disguised - our most dangerous fish on the reef.
0:05:00 > 0:05:03This is a...
0:05:04 > 0:05:07It's a superlative hunter.
0:05:09 > 0:05:14It tends to do most of its real hunting at night when it gets dark.
0:05:14 > 0:05:18This time of the day you can really appreciate
0:05:18 > 0:05:21its incredible camouflage, though.
0:05:21 > 0:05:24What's interesting is that as I'm getting close to it
0:05:24 > 0:05:27and it can feel me and it's feeling a little bit threatened by me...
0:05:29 > 0:05:33..all of those dorsal spines are going up on its back.
0:05:34 > 0:05:37At the base of each one of those is a venom gland
0:05:37 > 0:05:40with a really, really potent toxin.
0:05:42 > 0:05:44People who have been stung by this fish
0:05:44 > 0:05:47have called it the worst pain on the planet.
0:05:47 > 0:05:53While I've been talking about this superb ambush predator
0:05:53 > 0:05:54with great camouflage,
0:05:54 > 0:05:57there is an even better one just here. Look at this!
0:06:01 > 0:06:09Now this beautiful creature is a...
0:06:09 > 0:06:13You might be struggling to see it at the moment
0:06:13 > 0:06:17and I'm not surprised, because it is,
0:06:17 > 0:06:21I think, one of the most extraordinarily well-hidden creatures
0:06:21 > 0:06:22on the reef.
0:06:22 > 0:06:28With a big flat snout on it, it does look like a crocodile.
0:06:28 > 0:06:30Oh, it's moving.
0:06:30 > 0:06:33All of a sudden.
0:06:33 > 0:06:37In that split second when he starts moving,
0:06:37 > 0:06:39then he becomes very, very clear.
0:06:39 > 0:06:41And then he settles,
0:06:41 > 0:06:43and you wouldn't see him again.
0:06:46 > 0:06:48Great stuff.
0:06:56 > 0:06:57Ah, wow!
0:06:57 > 0:06:59Look at that!
0:07:03 > 0:07:05I've never seen one of these before.
0:07:05 > 0:07:10It's got to be one of the weirdest creatures in the sea.
0:07:10 > 0:07:12It's a....
0:07:12 > 0:07:17This is the ultimate ambush predator.
0:07:17 > 0:07:20It's all about just waiting
0:07:20 > 0:07:23for food to come to it.
0:07:23 > 0:07:30What it does, the frogfish will wait until it comes really, really close
0:07:30 > 0:07:35and bam, grab a hold of anything that's too close.
0:07:35 > 0:07:39Oh, hang on. Ha-ha!
0:07:39 > 0:07:42I can't believe I missed this.
0:07:42 > 0:07:44That's number one -
0:07:44 > 0:07:46there's another one down there!
0:07:46 > 0:07:49This is a totally different giant frogfish.
0:07:49 > 0:07:52Same creature but just a different colour.
0:07:52 > 0:07:54Look at that!
0:07:54 > 0:07:57I actually wonder if this is a male and a female.
0:07:57 > 0:08:00I'm sat here talking about this one for ages
0:08:00 > 0:08:04and that one under there, I completely missed it.
0:08:04 > 0:08:06It just proves how good the camouflage is on these creatures.
0:08:09 > 0:08:11You wouldn't want to be a little fish here.
0:08:11 > 0:08:14There are ambush predators everywhere.
0:08:14 > 0:08:16I can't sit here all day waiting for them to hunt,
0:08:16 > 0:08:17because I'd run out of air.
0:08:17 > 0:08:19So it's back to the surface.
0:08:20 > 0:08:23This is like diving in the world's biggest aquarium.
0:08:25 > 0:08:28How on earth am I going to choose my Deadly 60 creature out of that?
0:08:28 > 0:08:31Every single thing down there is deadly!
0:08:33 > 0:08:36I like it here, quite a lot!
0:08:36 > 0:08:37If you had to pick one,
0:08:37 > 0:08:42- and I'm forcing you to pick one, what would it be?- Erm...!
0:08:42 > 0:08:44Erm...!
0:08:44 > 0:08:47Erm...!
0:08:47 > 0:08:51Well, for once I'm totally indecisive and can't make up my mind,
0:08:51 > 0:08:53so we return to base.
0:08:57 > 0:08:59And then as the sun went down,
0:08:59 > 0:09:03hanging around in the lights of the dive centre was an animal
0:09:03 > 0:09:06that practically made the decision for me.
0:09:06 > 0:09:09Simon the cameraman and I just had to get in and film it.
0:09:12 > 0:09:15Out here on the sea bottom...
0:09:15 > 0:09:19is one of the most beautiful predators
0:09:19 > 0:09:22that you'll find anywhere in the sea.
0:09:22 > 0:09:26This incredible creature is a lionfish.
0:09:28 > 0:09:30It's a superlative predator.
0:09:31 > 0:09:36Those huge fans that he has held out to the side
0:09:36 > 0:09:41and the spines all down the top of his back
0:09:41 > 0:09:43are all super sharp.
0:09:43 > 0:09:46And at the base of them is a venom gland
0:09:46 > 0:09:47packed with poison.
0:09:50 > 0:09:52All of that can be very dangerous to something large
0:09:52 > 0:09:54that might threaten the lionfish.
0:09:55 > 0:09:59But when it's catching its prey,
0:09:59 > 0:10:03it just relies on speed and super powerful strike.
0:10:06 > 0:10:08Oh, dear -
0:10:08 > 0:10:10there's a small fish over here.
0:10:10 > 0:10:14It really doesn't know the kind of trouble it's getting itself into.
0:10:14 > 0:10:16The lionfish has spotted it.
0:10:18 > 0:10:20This could be trouble.
0:10:22 > 0:10:25It's moving in.
0:10:25 > 0:10:28Oh! Oh!
0:10:28 > 0:10:30Unbelievable!
0:10:32 > 0:10:35Can you see the speed of that strike?
0:10:40 > 0:10:42That is so cool!
0:10:44 > 0:10:46Oh, look, it's about to happen again.
0:10:49 > 0:10:53I have a feeling it could well be dinner time.
0:10:54 > 0:10:57Oh, no. Don't do it! Don't do it!
0:10:57 > 0:10:59You're in so much trouble.
0:10:59 > 0:11:01He did it again!
0:11:04 > 0:11:06This is just unbelievable.
0:11:06 > 0:11:10Astounding display of feeding... I think, I've ever seen.
0:11:16 > 0:11:19All of the light we are creating here
0:11:19 > 0:11:22is attracting all of these tiny little fish.
0:11:22 > 0:11:26That's like an all-you-can-eat buffet for the lionfish.
0:11:30 > 0:11:35They can just hang around until the perfect bite-size morsel turns up.
0:11:35 > 0:11:38It's kind of hard for us, myself and the cameraman -
0:11:38 > 0:11:41we really have to watch where we're kicking our fins
0:11:41 > 0:11:45and putting out hands, because those venomous spines...
0:11:45 > 0:11:53well, they could actually be pretty dangerous even to a person.
0:11:53 > 0:11:57Certainly the sting would be as powerful as many venomous snakes.
0:11:58 > 0:12:01Almost everything leaves the lionfish alone.
0:12:03 > 0:12:05It's not surprising really.
0:12:07 > 0:12:08Oh!
0:12:09 > 0:12:12Oh! Unbelievable!
0:12:22 > 0:12:26Well, I reckon in its way
0:12:26 > 0:12:28that's every bit as impressive
0:12:28 > 0:12:32as watching ACTUAL lions hunting in Africa.
0:12:32 > 0:12:34They have lethal venomous spines.
0:12:34 > 0:12:37Nobody messes with a lionfish.
0:12:37 > 0:12:40They're one of the fastest striking fish I've ever seen.
0:12:40 > 0:12:44They're kind of like ninjas in stripy orange pyjamas,
0:12:44 > 0:12:48and the lionfish is definitely going on the Deadly 60.
0:12:50 > 0:12:52With defensive venomous spines
0:12:52 > 0:12:54that can cripple a person just with pain alone
0:12:54 > 0:12:56and a super fast gulp,
0:12:56 > 0:12:59seeing these lionfish hunt in front of me
0:12:59 > 0:13:01has earned them a spot on the Deadly 60.
0:13:05 > 0:13:07I've done my buddy check. Fine.
0:13:07 > 0:13:10Jim and Steve will do theirs.
0:13:10 > 0:13:14'The waters around these tropical islands are berserk with wildlife.
0:13:14 > 0:13:17'But to give myself the best chance of finding the deadly ones,
0:13:17 > 0:13:20'we're cutting through the waves bound for the coral reef.'
0:13:25 > 0:13:27Most of the places we go to on the Deadly 60
0:13:27 > 0:13:30we're going out with a good idea of the sort of animals
0:13:30 > 0:13:31we're likely to find,
0:13:31 > 0:13:34but it just isn't like that when you're diving.
0:13:34 > 0:13:38Especially on a coral reef, where anything can turn up.
0:13:40 > 0:13:44Really, the next dive I could find a tiny brightly coloured fish
0:13:44 > 0:13:46I've never seen before the size of my finger,
0:13:46 > 0:13:49or I could get chased by a shark the size of the boat.
0:13:49 > 0:13:51You just never know what you're going to find,
0:13:51 > 0:13:53and that's what makes it so much fun.
0:14:08 > 0:14:11A coral reef is a living thing.
0:14:11 > 0:14:15Well, actually several billion living things,
0:14:15 > 0:14:18all clustered together like some undersea city.
0:14:19 > 0:14:22The building blocks of the city are the shell-like skeletons
0:14:22 > 0:14:25of millions of microscopic animals
0:14:25 > 0:14:28that have built up over thousands of years.
0:14:29 > 0:14:33The lumps of coral provide shelter and some surprising animals.
0:14:36 > 0:14:40Wow! This is something you don't see very often -
0:14:40 > 0:14:43a turtle properly sleeping.
0:14:44 > 0:14:46Look at that!
0:14:47 > 0:14:49Sea turtles can sleep underwater,
0:14:49 > 0:14:53because they can stay submerged for three hours!
0:14:56 > 0:14:59The reef's not just about shelter.
0:14:59 > 0:15:03Because it's a living thing, there are animals that will eat it.
0:15:04 > 0:15:06Look at this!
0:15:08 > 0:15:11These are...
0:15:11 > 0:15:14As you can see, they're feeding on the coral,
0:15:14 > 0:15:17munching it down with their hard beaks.
0:15:20 > 0:15:23These bumphead parrotfish are about half as big as me.
0:15:23 > 0:15:25They graze on the reef like cows graze on a field
0:15:25 > 0:15:31and poo out a fine powder that ends up as sand on tropical beaches.
0:15:32 > 0:15:35But some reef fish eat even stranger things for dinner.
0:15:37 > 0:15:41These plate-shaped fish are called batfish.
0:15:43 > 0:15:45They're well-known for hanging around
0:15:45 > 0:15:48where there's lots of turtles, feeding...
0:15:48 > 0:15:51Well, there's no nice way of putting this -
0:15:51 > 0:15:54they eat turtle poo.
0:15:54 > 0:15:59It seems like a weird way to make a living.
0:15:59 > 0:16:04Speaking of turtles, it seems our sleepy friend has woken up.
0:16:04 > 0:16:06What a wonderful creature.
0:16:16 > 0:16:19It doesn't get much more beautiful than that.
0:16:22 > 0:16:24There are so many beautiful animals here,
0:16:24 > 0:16:28I just don't know where to look. But the reef has a dark side.
0:16:28 > 0:16:32Already, I can see clues that there are deadly predators about.
0:16:32 > 0:16:34See what happens.
0:16:34 > 0:16:36As a large fish gets close...
0:16:37 > 0:16:41..they all disappear into the coral.
0:16:41 > 0:16:44The tiny fish duck into the shelter of the reef as I pass.
0:16:44 > 0:16:45I'd never be able to catch them,
0:16:45 > 0:16:48but there are plenty of fish around here that could.
0:16:51 > 0:16:53These are...
0:16:55 > 0:17:00They're a very fast-moving fish,
0:17:00 > 0:17:04sticking together and hunting in huge silvery schools like this.
0:17:10 > 0:17:16It's an amazing sensation to be totally immersed in fish like this.
0:17:16 > 0:17:21Nothing wants to get caught in the open by these guys.
0:17:21 > 0:17:25And then another silent hunter, a white-tip reef shark.
0:17:26 > 0:17:30How about that! I tell you what, I've not seen that before.
0:17:30 > 0:17:34It's almost as if the trevally are mobbing him.
0:17:36 > 0:17:40The trevally mob the shark like a small bird will mob a bird of prey,
0:17:40 > 0:17:42driving it from their territory.
0:17:42 > 0:17:45The powerful shark gives way to the greater number of trevally.
0:17:45 > 0:17:47And he's gone!
0:17:55 > 0:17:57The coral city is buzzing with life
0:17:57 > 0:18:01and a fair few candidates for my Deadly 60 list.
0:18:04 > 0:18:07Before I decide, I want to dive when it's dark
0:18:07 > 0:18:09and check out the night life.
0:18:16 > 0:18:19At night, the sea changes character completely.
0:18:19 > 0:18:23Plant-feeding animals hide away, and the predators start to hunt,
0:18:23 > 0:18:25which means more deadly animals.
0:18:32 > 0:18:37Loads of creatures with teeth, stings and tentacles,
0:18:37 > 0:18:38all out looking for food.
0:18:45 > 0:18:47I'm approaching very slowly.
0:18:49 > 0:18:51Very purposely...
0:18:53 > 0:18:55..because what lives in this hole here
0:18:55 > 0:18:58is an animal I've been trying to find
0:18:58 > 0:19:01for many years.
0:19:01 > 0:19:04One of the most remarkable creatures
0:19:04 > 0:19:07you'll find anywhere around here
0:19:07 > 0:19:10and possibly THE most amazing hunter.
0:19:10 > 0:19:11It's called the mantis shrimp.
0:19:11 > 0:19:15Let's see if we can get it out to play.
0:19:16 > 0:19:21Shrimp by name, but certainly not by nature, this is a lethal assassin.
0:19:24 > 0:19:26Oh!
0:19:34 > 0:19:37That was absolutely remarkable!
0:19:37 > 0:19:40The mantis shrimp strikes!
0:19:40 > 0:19:43It's back in its hole.
0:19:45 > 0:19:47Wow!
0:19:52 > 0:19:53Ha-ha!
0:19:53 > 0:19:56When they come out and they catch that shrimp
0:19:56 > 0:19:58just like a preying mantis would.
0:20:00 > 0:20:03In fact, this stunning killer is neither mantis
0:20:03 > 0:20:04nor even a true shrimp.
0:20:04 > 0:20:07Some species are known as thumb splitters
0:20:07 > 0:20:10for the damage they've done to divers.
0:20:10 > 0:20:11Ouch!
0:20:12 > 0:20:17Any small fish that gets too close to the burrow is going to be history!
0:20:17 > 0:20:20But today, my thumbs are not on the menu!
0:20:22 > 0:20:24It's the king of ambush predators,
0:20:24 > 0:20:27waiting patiently for its prey...
0:20:27 > 0:20:32then bang, the mantis shrimp uses its claws like some medieval weapon
0:20:32 > 0:20:38to stun, then impale its victim before dismantling and devouring it.
0:20:38 > 0:20:41Ah!
0:20:42 > 0:20:46That...was so fast!
0:20:47 > 0:20:49I've heard it said that that strike
0:20:49 > 0:20:55can be as fast and have as much power as a small-calibre bullet.
0:20:59 > 0:21:02I can't say I disagree.
0:21:05 > 0:21:09It has to be one of the most stunning animals you'll find around here.
0:21:09 > 0:21:11The mantis shrimp -
0:21:11 > 0:21:14absolutely awe-inspiring!
0:21:20 > 0:21:23With some species punching with the power of a bullet,
0:21:23 > 0:21:26the mantis shrimp is one awesome animal -
0:21:26 > 0:21:29wicked weapons, scintillating speed.
0:21:29 > 0:21:32One of my favourite Deadly 60 stars.
0:21:36 > 0:21:41Between all of the diving, we hang out with the Badajoz sea gypsies
0:21:41 > 0:21:43who live on the island and in the sea around the reef.
0:21:43 > 0:21:44Hello!
0:21:50 > 0:21:53The world beneath their boats is a multi-coloured dream
0:21:53 > 0:21:56of dazzling marine creatures. But for the moment,
0:21:56 > 0:22:00the most fascinating thing to them is our cameras.
0:22:02 > 0:22:05We've had a tip-off. There's one place around here
0:22:05 > 0:22:09that attracts the largest, most powerful predators,
0:22:09 > 0:22:14so that's exactly where we're diving now, to find my last deadly animal.
0:22:15 > 0:22:20It's not far from the reef. In fact, it's the edge of it.
0:22:20 > 0:22:23The reef really feels like home...
0:22:24 > 0:22:28..when just at the end of it you've got this.
0:22:30 > 0:22:32The drop off.
0:22:33 > 0:22:37This is where the reef meets the open ocean.
0:22:41 > 0:22:47The drop off disappears 600 metres straight down into the abyss.
0:22:47 > 0:22:49It gives you vertigo.
0:22:51 > 0:22:53It's like stepping off the edge of a cliff
0:22:53 > 0:22:56with the big blue beneath you.
0:22:57 > 0:23:02There are still plenty of fish here, but they daren't stray too far
0:23:02 > 0:23:07from the wall, because the open ocean is full of lethal killers.
0:23:08 > 0:23:13In keeping closer to the coral, it keeps them safe from the big fish
0:23:13 > 0:23:14with the big teeth.
0:23:14 > 0:23:17And then looming out of the deep blue,
0:23:17 > 0:23:19one of the fastest assassins in the sea.
0:23:19 > 0:23:23Steve, check out the fish up above you.
0:23:23 > 0:23:29Dogtooth tuna - with power, speed and sharp teeth, this is the real deal.
0:23:30 > 0:23:33It's swimming straight at our cameraman -
0:23:33 > 0:23:35look at that! Gulping, his mouth open.
0:23:43 > 0:23:46Wonderful stuff!
0:23:46 > 0:23:47I love it!
0:23:54 > 0:23:56Fierce hunters stalk the depths, just waiting
0:23:56 > 0:23:59for a small fish to stray too far from home.
0:23:59 > 0:24:02This is another one of the speed merchants of the sea.
0:24:03 > 0:24:05It's a giant trevally.
0:24:05 > 0:24:07There's another one over there as well.
0:24:09 > 0:24:11Look at the size of him!
0:24:11 > 0:24:14Absolutely huge.
0:24:14 > 0:24:16They're exceptional hunters.
0:24:16 > 0:24:20At the moment, they're just curling along the outside...
0:24:23 > 0:24:25..looking for something to snap up.
0:24:27 > 0:24:29No way I'm keeping up with them.
0:24:30 > 0:24:35Cruising through crystal seas, the sun cuts down through the blue.
0:24:35 > 0:24:38Then suddenly, it seemed a huge cloud blocked out the sun.
0:24:38 > 0:24:41But it wasn't a cloud.
0:24:41 > 0:24:46It was one of the world's most awe-inspiring wildlife spectacles.
0:24:46 > 0:24:50That is the largest school of barracuda I've ever seen.
0:24:55 > 0:24:58This is absolutely dazzling.
0:24:58 > 0:25:00One of the meanest...
0:25:00 > 0:25:05fastest, fiercest fish in the sea.
0:25:06 > 0:25:09And I've never seen so many of them.
0:25:09 > 0:25:10Ha-ha-ha!
0:25:19 > 0:25:22That is unbelievable!
0:25:22 > 0:25:25Absolutely surrounded by them.
0:25:44 > 0:25:46I've never seen anything like it!
0:25:46 > 0:25:49They're almost surrounding me in a circle.
0:25:53 > 0:25:56Spinning around and around.
0:25:56 > 0:26:01This is absolutely dazzling.
0:26:13 > 0:26:16Barracuda are all about teeth.
0:26:16 > 0:26:20They have two sets - the huge long teeth at the front are used to grab
0:26:20 > 0:26:25their prey, but the real damage is done by the teeth at the back.
0:26:25 > 0:26:29They act like scissors, cutting prey in half in a single bite.
0:26:29 > 0:26:31Even sharks can't do that.
0:26:31 > 0:26:34When you're diving with barracuda, it's wise to keep your hands
0:26:34 > 0:26:37tucked in and don't show off silvery items like watches,
0:26:37 > 0:26:41otherwise they might mistake it for a small fish
0:26:41 > 0:26:43and then you're going to lose your hand.
0:26:43 > 0:26:48Look at them! There are thousands of them!
0:26:51 > 0:26:53I've never seen anything like it!
0:26:56 > 0:27:00Although they look totally effortless in the way they move,
0:27:00 > 0:27:05actually they're really travelling quite fast.
0:27:05 > 0:27:09I'm breathing pretty heavily just keeping up with them.
0:27:12 > 0:27:15Barracuda -
0:27:15 > 0:27:19definitely going on my Deadly 60.
0:27:22 > 0:27:24Hanging around in whirlwind shoals,
0:27:24 > 0:27:27lightning fast with terrifying teeth,
0:27:27 > 0:27:29barracuda are the wolves of the sea.
0:27:29 > 0:27:31We finished with the very best,
0:27:31 > 0:27:34one of the most dazzling spectacles I've ever seen
0:27:34 > 0:27:36and undoubtedly deadly.
0:27:36 > 0:27:39Coming up next time, as I continue my search for the Deadly 60...
0:27:39 > 0:27:43I have to say, I will treasure this forever.
0:27:43 > 0:27:45Argh! Argh!
