0:00:02 > 0:00:04My name's Steve Backshall.
0:00:09 > 0:00:11I'm on a mission to find the Deadly 60.
0:00:11 > 0:00:15That's 60 deadly creatures from around the world.
0:00:17 > 0:00:19And you're coming with me every step of the way.
0:00:19 > 0:00:21Ow!
0:00:31 > 0:00:34This time on Deadly 60, we're in the Bahamas -
0:00:34 > 0:00:39here - and we're looking for one very special kind of animal.
0:00:40 > 0:00:41Sharks!
0:00:45 > 0:00:48The Bahamas is a real global hotspot for sharks.
0:00:48 > 0:00:51It's not just the amount of sharks down here,
0:00:51 > 0:00:53but all different kinds of species of sharks.
0:00:53 > 0:00:57All those weird and wonderful creatures don't just look different,
0:00:57 > 0:01:00they have different kinds of prey, they're found in different parts
0:01:00 > 0:01:03of the ocean and have different behaviours.
0:01:03 > 0:01:05I'm looking for three sharks for my list
0:01:05 > 0:01:08and each one has a very different way of hunting.
0:01:12 > 0:01:14First up is one of the most manoeuvrable sharks
0:01:14 > 0:01:17in the Caribbean. The king of the coral reef,
0:01:17 > 0:01:18the reef shark.
0:01:18 > 0:01:21Helping me, as ever, are my crew,
0:01:21 > 0:01:25including underwater cameraman, Simon,
0:01:25 > 0:01:29and from the nearby Sharklab, Dr Sam Gruber,
0:01:29 > 0:01:31also known as the Doc.
0:01:34 > 0:01:37The minute we arrive at the reef, Doc and his Sharklab crew
0:01:37 > 0:01:42start dishing the goodies to bring in the sharks, while cameraman,
0:01:42 > 0:01:45Simon, gets in position below the boat.
0:01:45 > 0:01:50The divers are barely in the water when our first guest turns up.
0:01:53 > 0:01:56A lot of people around the world are terrified of going into the sea,
0:01:56 > 0:01:59because of just this. That dorsal fin cutting the surface.
0:01:59 > 0:02:03Sharks really are an element of fear for people all over the world.
0:02:03 > 0:02:05Look at this. Coming right in close!
0:02:05 > 0:02:08I guess one of the central problems is the image of
0:02:08 > 0:02:10the shark-feeding frenzy.
0:02:10 > 0:02:13The idea that as soon as any bit of blood goes in the water,
0:02:13 > 0:02:16sharks will come in from miles around and as soon as they're there,
0:02:16 > 0:02:18they're just gonna go crazy,
0:02:18 > 0:02:21attacking everything that moves and killing and eating it.
0:02:21 > 0:02:24People have an idea of sharks as being these crazed man-eaters,
0:02:24 > 0:02:26but that simply isn't true.
0:02:28 > 0:02:31What I want to prove is that sharks are way smarter and
0:02:31 > 0:02:34way more selective about what they eat than people think.
0:02:34 > 0:02:36And the best way to do that is to bring them in and
0:02:36 > 0:02:38then go in and join them.
0:02:40 > 0:02:43No matter how many times I do this, there's still that
0:02:43 > 0:02:46feeling of excitement coming up from your stomach when
0:02:46 > 0:02:48you're getting ready to get in the water with sharks.
0:02:48 > 0:02:52Particularly when they're as active as these ones.
0:02:52 > 0:02:56I have to be very careful, to go in quite quietly and carefully.
0:02:56 > 0:03:00Not because the sharks are gonna go for me,
0:03:00 > 0:03:03but more that they're likely to be frightened off.
0:03:03 > 0:03:07Also have to be careful when you're in the water not to thrash around
0:03:07 > 0:03:10with your hands, because all of a sudden, these white fingers
0:03:10 > 0:03:13could well turn into little fishies in the shark's eye.
0:03:16 > 0:03:17Good luck, Steve-O.
0:03:27 > 0:03:33As far as I can see, I've got three big Caribbean reef sharks
0:03:33 > 0:03:34already coming in very close.
0:03:34 > 0:03:36They don't seem too frightened of me.
0:03:36 > 0:03:39Absolutely magnificent creatures.
0:03:46 > 0:03:49You can see how fearless they are.
0:03:49 > 0:03:52Three of them have just swam straight into the lens
0:03:52 > 0:03:54of the camera. If I wasn't pushing them off with this,
0:03:54 > 0:03:57they'd probably have been swimming into me!
0:04:02 > 0:04:05We've got six now! Six big Caribbean reef sharks.
0:04:05 > 0:04:11As they're coming in right up close, taking food right form in front of
0:04:11 > 0:04:14the camera, they're revealing those sharp teeth.
0:04:14 > 0:04:18The thing that really sets the Caribbean reef shark apart
0:04:18 > 0:04:22is it's manoeuvrability. It can snap almost back on itself
0:04:22 > 0:04:25with its head and snap bait right next to the side of it.
0:04:34 > 0:04:38That was too close! Way too close!
0:04:46 > 0:04:49I've been in the water with these sharks feeding
0:04:49 > 0:04:50for about 15 minutes now.
0:04:50 > 0:04:54They've bumped me, they've bumped the camera, they've bumped
0:04:54 > 0:04:58each other, but I've still got all my fingers, still got all my toes.
0:04:58 > 0:05:01It's pretty obvious that they're not interested in me to eat.
0:05:01 > 0:05:04But for their manoeuvrability, for the speed and for
0:05:04 > 0:05:07their razor-sharp teeth, the reef sharks are our first sharks
0:05:07 > 0:05:08on the Deadly 60.
0:05:10 > 0:05:12That was amazing!
0:05:14 > 0:05:16In the reef world here in the Bahamas,
0:05:16 > 0:05:18nothing hunts fish
0:05:18 > 0:05:19better than these guys.
0:05:21 > 0:05:24Fast, agile and packed with muscle,
0:05:24 > 0:05:26the Caribbean reef shark.
0:05:31 > 0:05:35The centre for shark research here in the Bahamas is called Sharklab.
0:05:35 > 0:05:38Run by the Doc, his team study pretty much
0:05:38 > 0:05:41all the shark species in the area.
0:05:41 > 0:05:46To help their research, they keep some baby sharks for a while
0:05:46 > 0:05:48in pens, just off the beach.
0:05:48 > 0:05:50Here at Sharklab, we get a unique opportunity
0:05:50 > 0:05:52to get close to some baby sharks.
0:05:52 > 0:05:55They are so cute, you are just not gonna believe it.
0:05:55 > 0:05:59OK, so these babies are not exactly deadly, but they have
0:05:59 > 0:06:04the same awesome sensory abilities that adult sharks do.
0:06:04 > 0:06:06Seeing them up close will give me an insight into
0:06:06 > 0:06:08what makes the adults deadly predators.
0:06:08 > 0:06:12Now, if you'll just stay on this fence here
0:06:12 > 0:06:16and walk around that way, I'll try to bring these guys to you.
0:06:16 > 0:06:18Here we go, here we go.
0:06:18 > 0:06:20Yeah!
0:06:24 > 0:06:27So there we go. Our first baby shark.
0:06:27 > 0:06:28I'd be careful, now. Really.
0:06:28 > 0:06:30OK, now, this is just the baby shark -
0:06:30 > 0:06:32I do need to be quite careful
0:06:32 > 0:06:35about how I handle it, cos this is a lemon shark
0:06:35 > 0:06:38and this species is well-known for being incredible mobile.
0:06:38 > 0:06:41They can whip right round and bite their own tail.
0:06:41 > 0:06:44So, actually, if I let go with my right hand now,
0:06:44 > 0:06:46I would almost certainly get bitten.
0:06:46 > 0:06:50What we can do is - let's put him in tonic immobility.
0:06:50 > 0:06:52Put him to sleep, now, together.
0:06:52 > 0:06:54- Just roll him over like that, hold his tail.- OK.
0:06:54 > 0:06:58Now he's gonna go to sleep.
0:06:58 > 0:07:01So what's the theory with these sharks? You flip them over and
0:07:01 > 0:07:03they almost act as though they're hypnotised.
0:07:03 > 0:07:06They are. We also call it animal hypnosis.
0:07:06 > 0:07:10When you turn their senses around and make everything the wrong way,
0:07:10 > 0:07:14it confuses the animal and there's so much sensory input that they
0:07:14 > 0:07:17just go into this state of relaxation.
0:07:17 > 0:07:19This does actually work for adult sharks
0:07:19 > 0:07:22- as well as for juniors, doesn't it?- Yes, it does.
0:07:22 > 0:07:27We have five senses, but these baby sharks have an extra two,
0:07:27 > 0:07:30giving them the power to detect movement and electricity in water.
0:07:34 > 0:07:36Take our hypnotised shark...
0:07:36 > 0:07:38and we'll wake her up.
0:07:41 > 0:07:43There she goes. Look at that! Almost as soon as
0:07:43 > 0:07:46she turns back over, starts moving again. It's incredible.
0:07:46 > 0:07:49Right, it's a very special day for this little lemon shark.
0:07:49 > 0:07:52It's time for her to go back into the wild.
0:07:52 > 0:07:54Come on, little lady!
0:07:59 > 0:08:03He's certainly feeling very excited at being back out in the sea.
0:08:03 > 0:08:06I reckon if we release him now, he's gonna be right at home.
0:08:07 > 0:08:09There you go.
0:08:10 > 0:08:12Wow!
0:08:13 > 0:08:18Ha! Actually jumped right on Simon the cameraman.
0:08:22 > 0:08:23It's just over there.
0:08:23 > 0:08:26I'm hoping to see some adult lemon sharks a bit later on.
0:08:26 > 0:08:31But now, we're heading out to find my next Deadly 60 animal.
0:08:32 > 0:08:33Tiger sharks.
0:08:33 > 0:08:38These huge predators prefer to live off-shore and in deep water.
0:08:38 > 0:08:42One way Doc can study them in this area is to bait long lines
0:08:42 > 0:08:45right down to the sea bed, hundreds of metres below and
0:08:45 > 0:08:47check them very few hours.
0:08:51 > 0:08:53Ho! Woo!
0:08:56 > 0:08:58We got something!
0:08:58 > 0:09:00We got a small tiger shark.
0:09:02 > 0:09:05Couldn't even feel it pulling until the very last minute.
0:09:05 > 0:09:08Just on the end of the line, here.
0:09:11 > 0:09:13He's not very big.
0:09:13 > 0:09:16Probably two and a half metres.
0:09:18 > 0:09:22OK, so the first thing we need to do is to bring the tiger along side
0:09:22 > 0:09:27and then the Doc, here, has certain tests he needs to do on it.
0:09:27 > 0:09:30Take some blood, get the length and the approximate weight of it.
0:09:30 > 0:09:33Wow.
0:09:33 > 0:09:36This information is crucial to help Doc's team find out
0:09:36 > 0:09:39as much as possible about these secretive animals.
0:09:39 > 0:09:42I know this looks really stressful for the shark,
0:09:42 > 0:09:44but they are such tough creatures.
0:09:44 > 0:09:47OK.
0:09:52 > 0:09:53OK, 172.
0:09:53 > 0:09:56It's really important that we minimise the amount of time that
0:09:56 > 0:09:58we have this shark kept like this.
0:09:58 > 0:10:00Now, all we really need to do is just to tag it,
0:10:00 > 0:10:03so we can identify the individual, and then let it go.
0:10:03 > 0:10:06OK, there you go.
0:10:07 > 0:10:12That's the tag in there and the tag number is 323871.
0:10:12 > 0:10:15Now we need to let this wonderful creature go.
0:10:15 > 0:10:17But in order to get it to get moving again,
0:10:17 > 0:10:20I'm gonna need to get in the water with it
0:10:20 > 0:10:22and help it start swimming.
0:10:22 > 0:10:25The shark's groggy form lack of oxygen,
0:10:25 > 0:10:28so it's important that someone swims alongside,
0:10:28 > 0:10:30keeping its head into the current,
0:10:30 > 0:10:33forcing water into its gills until it's moving strongly.
0:10:33 > 0:10:36Today, that's gonna be my job.
0:11:18 > 0:11:20It's gonna be OK. It's gonna be fine.
0:11:20 > 0:11:21That was amazing.
0:11:21 > 0:11:24Just disappeared off into the blue.
0:11:24 > 0:11:25He was totally unharmed.
0:11:25 > 0:11:28A little bit shocked by the whole experience, I think.
0:11:28 > 0:11:29But he's gonna be OK.
0:11:29 > 0:11:32What a beautiful, beautiful creature.
0:11:32 > 0:11:35He gave Simon the cameraman a little bit of a shock, though.
0:11:35 > 0:11:38Nearly took a right bite out of the camera.
0:11:38 > 0:11:39Wow.
0:11:44 > 0:11:46We were just pulling up the rest of the line,
0:11:46 > 0:11:50fully expecting there not to be anything else on it,
0:11:50 > 0:11:53and we've had a real surprise.
0:11:53 > 0:11:56This big animal is a tiger shark.
0:11:56 > 0:11:59And the most amazing thing about it is, despite the fact that
0:11:59 > 0:12:01it's absolutely huge, it's a male!
0:12:01 > 0:12:04Usually, the really big animals are the females.
0:12:04 > 0:12:06You got it?
0:12:10 > 0:12:11Good job.
0:12:11 > 0:12:13This monster shark is an old friend
0:12:13 > 0:12:16and has already been tagged by Doc and his team.
0:12:16 > 0:12:18This is great news for their research
0:12:18 > 0:12:21and means we don't need to measure him again.
0:12:21 > 0:12:25It's a monster! This is a unique opportunity for me to show you,
0:12:25 > 0:12:29up close, some of what makes this shark so special.
0:12:30 > 0:12:35If I just lift the snout out of the water,
0:12:35 > 0:12:39we might be able to show you...
0:12:39 > 0:12:40those incredible teeth.
0:12:40 > 0:12:48The tiger shark is probably the most generalist feeder of all sharks.
0:12:48 > 0:12:51They'll take an incredible variety of prey.
0:12:51 > 0:12:56from turtles and bits of carrion that are just floating in the water,
0:12:56 > 0:13:00through to fish - even sea birds.
0:13:00 > 0:13:04And their remarkable teeth act like can openers.
0:13:04 > 0:13:08They'll easily scissor through the shell of a turtle.
0:13:09 > 0:13:14I cannot believe I'm this close to this incredible animal.
0:13:14 > 0:13:18This has to rank up there with the greatest experiences of my life.
0:13:18 > 0:13:22What a privilege. Look at the size of him!
0:13:22 > 0:13:24What do you say we release him?
0:13:24 > 0:13:26- I think that's a great idea.- Right.
0:13:33 > 0:13:38- Ready?- Ready?- He's all yours! Let him go.
0:14:15 > 0:14:19That might just be the coolest thing I've ever seen.
0:14:20 > 0:14:23Seeing that incredible prehistoric creature just
0:14:23 > 0:14:25heading off into the big blue.
0:14:25 > 0:14:29Just really... Wow.
0:14:29 > 0:14:31I dunno what to say.
0:14:31 > 0:14:36There's no doubt that I'm going to put tiger sharks on the Deadly 60.
0:14:36 > 0:14:39But first, I want to see them on their own terms,
0:14:39 > 0:14:40without catching them.
0:14:40 > 0:14:43So we've sailed far out to sea in the boat Indigo,
0:14:43 > 0:14:46to a place where we have a chance to see wild tiger sharks.
0:14:48 > 0:14:51It's called Tiger Beach.
0:14:54 > 0:14:56- Morning, Cap.- Morning.
0:14:56 > 0:15:00Oh-oh-oh-oh! Come and have a look at this.
0:15:09 > 0:15:16I can see one, two, three, four, five, six...
0:15:16 > 0:15:19six sharks already.
0:15:19 > 0:15:21I think this is going to be a pretty good day.
0:15:21 > 0:15:24Let's go down below, shall we?
0:15:24 > 0:15:27So far, the tigers are keeping their distance.
0:15:27 > 0:15:29These dark shapes belong to lemon sharks
0:15:29 > 0:15:32and they're next up for the list.
0:15:32 > 0:15:37- What do you reckon, Si? - Oh, I think it'll do, mate.
0:15:40 > 0:15:44These fully grown sharks couldn't be more different to the cute,
0:15:44 > 0:15:46vulnerable babies I'd seen back at Sharklab.
0:15:46 > 0:15:50And don't be fooled by their name. The only lemony thing about them
0:15:50 > 0:15:52is their colour.
0:15:52 > 0:15:55Particularly at dawn, dusk and in murky water, they are killers.
0:15:55 > 0:15:59And with more sensing capabilities than a submarine.
0:15:59 > 0:16:04If you're a fish, you can run, but hiding from them is not an option.
0:16:04 > 0:16:09Good job that it's day time and that I'm not a fish.
0:16:09 > 0:16:11Look at the size of that!
0:16:34 > 0:16:38We're absolutely surrounded by lemon sharks!
0:16:39 > 0:16:42Wow! What an unbelievable sight!
0:16:44 > 0:16:46Look at those one, here!
0:16:46 > 0:16:50This shark is absolutely covered in sucker fish.
0:16:50 > 0:16:53They're covering the body!
0:16:53 > 0:16:55Look at that!
0:16:56 > 0:16:59It's such a serene shark.
0:16:59 > 0:17:01They're totally unbothered by our presence.
0:17:03 > 0:17:06This is extraordinary!
0:17:09 > 0:17:13Oh! I've literally only just got in the water
0:17:13 > 0:17:18and I can already see, what, nine? Ten, I think!
0:17:18 > 0:17:20Ten adult lemon sharks.
0:17:20 > 0:17:25And they look like they're all fully grown females.
0:17:25 > 0:17:30You can see how incredibly close they're comfortable getting to me.
0:17:30 > 0:17:35They have absolutely no fear of me whatsoever.
0:17:38 > 0:17:43And why would they? In this environment, they really are king.
0:17:45 > 0:17:51They're very distinctive, with small yellow eyes and their mouth
0:17:51 > 0:17:54is just spilling over with teeth.
0:17:54 > 0:17:59These lemon sharks can turn right around and bite their own tail.
0:17:59 > 0:18:02They're that flexible.
0:18:04 > 0:18:07You can see how easily this amazing predator
0:18:07 > 0:18:10can suddenly become a terrible threat.
0:18:10 > 0:18:14I mean, we're in their environment, not they in ours.
0:18:14 > 0:18:17Although I'm not on the menu,
0:18:17 > 0:18:20these sharks can be incredibly intimidating.
0:18:20 > 0:18:24They'll go around, over and even through you after the bait.
0:18:24 > 0:18:27Just imagine if you were a fish and they were after you.
0:18:27 > 0:18:30Look how close they're getting to Simon the cameraman.
0:18:30 > 0:18:34They're probably sensing electricity from the camera.
0:18:39 > 0:18:40Thank you, Doc.
0:18:40 > 0:18:45This stick, here - at the end of it are two different kinds of metals
0:18:45 > 0:18:48and it gives off a weak electrical field,
0:18:48 > 0:18:51which the sharks can sense
0:18:51 > 0:18:55with loads of tiny sensors in their snout.
0:18:55 > 0:18:58They think that the end of the stick is food.
0:18:58 > 0:19:00Hey, there, big fella!
0:19:03 > 0:19:04See that?
0:19:04 > 0:19:07It's actually taking a bite of the stick.
0:19:07 > 0:19:09Incredible stuff.
0:19:14 > 0:19:20As for what I think about sharks and their lack of danger to humans,
0:19:20 > 0:19:24they're still a predator that's right at the top of their game
0:19:24 > 0:19:27and you can see why.
0:19:28 > 0:19:30Nothing rivals them.
0:19:31 > 0:19:36OK, no tigers yet, but these are the biggest, most imposing,
0:19:36 > 0:19:40free-swimming sharks I've seen so far and
0:19:40 > 0:19:42I suddenly feel a bit exposed.
0:19:49 > 0:19:51That was remarkable.
0:19:51 > 0:19:57Anybody thinks that sharks are mindless killers can think again.
0:19:57 > 0:20:00I mean, even when there's loads of food in the water
0:20:00 > 0:20:03and they're thrashing around, teeth and sharks everywhere,
0:20:03 > 0:20:05they still leave us well alone.
0:20:05 > 0:20:07That said, if you were a fish in there,
0:20:07 > 0:20:10and you were faced with that face full of teeth
0:20:10 > 0:20:13and those incredibly manoeuvrable bodies,
0:20:13 > 0:20:14you wouldn't stand a chance.
0:20:14 > 0:20:18And that's why the lemon shark is definitely going on the Deadly 60.
0:20:18 > 0:20:20Can I go back in now?
0:20:20 > 0:20:23THEY LAUGH Did you enjoy that?
0:20:25 > 0:20:28Super-sensitive electro sensors
0:20:28 > 0:20:29enable them to track their prey
0:20:29 > 0:20:31better than any submarine
0:20:31 > 0:20:33and they have the weapons
0:20:33 > 0:20:34to finish it off.
0:20:34 > 0:20:36The lemon shark.
0:20:42 > 0:20:47I got up this morning and there were absolutely no sharks around at all.
0:20:47 > 0:20:52And all of a sudden, one dark shape just appeared close to the boat.
0:20:52 > 0:20:55We're pretty sure it's a tiger shark.
0:20:55 > 0:20:59So we're gonna get in the water and see if we can get it to come close.
0:20:59 > 0:21:04There's just a few tantalising shapes just out here,
0:21:04 > 0:21:06probably 15 metres behind the boat.
0:21:06 > 0:21:08The only way we can really know for sure
0:21:08 > 0:21:10is to get in and get a good look.
0:21:10 > 0:21:12Look at the size of it!
0:21:12 > 0:21:17Right, before I jump in, I just want to show you what tigers can do
0:21:17 > 0:21:19when they push the nasty button.
0:21:21 > 0:21:25Tigers can vary their hunting strategy to whatever is available.
0:21:25 > 0:21:26Even sea birds aren't safe.
0:21:31 > 0:21:34There's not much that's subtle about their table manners.
0:21:34 > 0:21:36Imagine carving a Sunday roast with a chainsaw
0:21:36 > 0:21:38and you get the idea.
0:21:47 > 0:21:48Right, chaps.
0:21:54 > 0:21:55As we get into the water,
0:21:55 > 0:21:58the dark shapes move further away from the boat.
0:22:08 > 0:22:11While the dive team get down on to the bottom,
0:22:11 > 0:22:14it's crucial that the surface team keep the bait coming in
0:22:14 > 0:22:20to try and bring the shy tigers back and hopefully keep them interested.
0:22:24 > 0:22:27I reckon that barracuda head could feed me for a week!
0:22:27 > 0:22:31It's the perfect bait to bring tigers in.
0:22:31 > 0:22:35Damn few lemons around, though.
0:22:40 > 0:22:43Oh, look! We were right, there are tigers about!
0:22:44 > 0:22:47That's just a youngster, though.
0:22:47 > 0:22:51It's the same size as a fully grown lemon and it's just a baby.
0:22:51 > 0:22:55Completely different size and shape, though.
0:22:55 > 0:23:00And look at its back! The markings are much clearer at this age.
0:23:00 > 0:23:02That is beautiful.
0:23:02 > 0:23:06Do you see it's a bit less cocky than the lemon shark?
0:23:09 > 0:23:10So graceful, though.
0:23:10 > 0:23:13Go on. Go on, take it!
0:23:13 > 0:23:15Yes!
0:23:15 > 0:23:16Yes! Look at that!
0:23:19 > 0:23:21Wow, that is a powerful creature!
0:23:23 > 0:23:27I reckon she's giving the guys on the surface a hard time.
0:23:31 > 0:23:33Look at that thrashing!
0:23:33 > 0:23:36Ah, she's got a face full of fish, though.
0:23:38 > 0:23:40That's some reward.
0:23:40 > 0:23:45Oh! Oh, look! That's a seriously big tiger coming in.
0:23:45 > 0:23:47A huge female!
0:23:47 > 0:23:51I reckon that must be double the size of the baby.
0:23:51 > 0:23:54I bet that was the big shape we saw from the deck before.
0:23:57 > 0:24:01It's coming... She's coming right in, right up to Simon!
0:24:01 > 0:24:04I reckon she could swallow him in one go!
0:24:04 > 0:24:07She's like a swimming bus!
0:24:09 > 0:24:13I can't believe it! She's swimming right between us!
0:24:15 > 0:24:17Really, really cautious.
0:24:17 > 0:24:20The eyes are darting around.
0:24:20 > 0:24:25I don't think she's scared, but she's certainly not aggressive.
0:24:28 > 0:24:32This is why this place is called Tiger Beach.
0:24:33 > 0:24:37Sun, sand and tigers.
0:24:40 > 0:24:45I reckon in this situation the sharks are quite used to divers,
0:24:45 > 0:24:49you can see they're totally relaxed, so it's safe for me to be here.
0:24:49 > 0:24:52But that could change in a second.
0:24:54 > 0:24:56Let's be honest, if I got bitten by that,
0:24:56 > 0:25:00it would take more than a sticking plaster to fix it.
0:25:01 > 0:25:04Here we go.
0:25:04 > 0:25:06Now we're going to see her in action.
0:25:10 > 0:25:12Look at that!
0:25:16 > 0:25:18That is awesome.
0:25:19 > 0:25:23Those guys on top better be ready for the pull.
0:25:25 > 0:25:29I reckon she weighs, what, quarter of a tonne?
0:25:34 > 0:25:37I hope I don't get any closer than this.
0:25:37 > 0:25:40To be honest, she's being gentle.
0:25:40 > 0:25:44Those teeth can go straight through a turtle's shell.
0:25:47 > 0:25:50She's kind of more playing with it like a big puppy dog.
0:26:02 > 0:26:04That was unbelievable!
0:26:08 > 0:26:09Whoo-hoo!
0:26:15 > 0:26:17I don't think Steve wants to come out.
0:26:19 > 0:26:21He's like a kiddie in a sweet shop.
0:26:33 > 0:26:36Well...all my years diving with sharks
0:26:36 > 0:26:39and they still have the power to surpriseme.
0:26:39 > 0:26:43Even that huge bulldog of a female Tiger
0:26:43 > 0:26:47was just nosing cautiously between Simon the cameraman and I,
0:26:47 > 0:26:49It was almost like she was being polite
0:26:49 > 0:26:53and she didn't want to grab the bite, didn't want to jump the queue.
0:26:53 > 0:26:57For all that though the tiger shark has to be on the Deadly 60.
0:26:57 > 0:27:02They're big, they're powerful, they have enormous can opener teeth,
0:27:02 > 0:27:04and they're one of the wonders of the ocean.
0:27:04 > 0:27:07That was incredible.
0:27:10 > 0:27:13You could argue that tiger sharks deserve the "deadly" tag
0:27:13 > 0:27:15more than any other shark,
0:27:15 > 0:27:17because they hunt so many things -
0:27:17 > 0:27:21turtles, fish, seabirds, mammals.
0:27:21 > 0:27:23Certainly not me though!
0:27:25 > 0:27:26Join me next time...
0:27:26 > 0:27:29Ah! I can't believe how close we are!
0:27:29 > 0:27:31..for more deadly animal encounters.
0:27:31 > 0:27:33Like a little glow-in-the-dark brooch.
0:27:33 > 0:27:36This is officially the deadliest spider in the world
0:27:36 > 0:27:38in terms of its venom.
