0:00:02 > 0:00:06My name's Steve Backshall. Self-confessed shark obsessed.
0:00:06 > 0:00:08This is Shark Bites.
0:00:10 > 0:00:12There's one shark that has a reputation
0:00:12 > 0:00:14for being the most ravenous.
0:00:15 > 0:00:17The tiger shark.
0:00:17 > 0:00:19Often nicknamed the dustbin of the ocean,
0:00:19 > 0:00:24they've been known to swallow tin cans and even car number plates.
0:00:26 > 0:00:29But they're far from just mindless munchers.
0:00:29 > 0:00:33Hunting fast-moving fish and armoured turtles,
0:00:33 > 0:00:35they ambush their prey.
0:00:35 > 0:00:36But in the open ocean,
0:00:36 > 0:00:40how does the tiger shark manage a surprise attack?
0:00:40 > 0:00:43The warm waters of the Bahamas are home to this apex predator.
0:00:46 > 0:00:49A big tiger shark has teeth
0:00:49 > 0:00:52and bite force than can get through the shell of a turtle.
0:00:52 > 0:00:54So, this...
0:00:54 > 0:00:57Well, I think it's more for my peace of mind than anything else.
0:00:59 > 0:01:01Oh, my goodness!
0:01:03 > 0:01:06Well, this is why we came here to Tiger Beach.
0:01:07 > 0:01:10It's a true monster of a tiger shark.
0:01:10 > 0:01:14It's one of the largest purely predatory creatures on Earth.
0:01:14 > 0:01:16While I'm not on their menu,
0:01:16 > 0:01:18it doesn't stop them from being curious.
0:01:18 > 0:01:20And, as sharks don't have hands,
0:01:20 > 0:01:23they'll investigate with their teeth.
0:01:23 > 0:01:24It's going for your fin, Si.
0:01:24 > 0:01:26No, draw in your foot, draw in your foot, seriously.
0:01:26 > 0:01:28Whoa, whoa, whoa, Si, Si, Si!
0:01:32 > 0:01:34This is absolute chaos.
0:01:34 > 0:01:36They may be overly inquisitive,
0:01:36 > 0:01:40but these hungry hunters rely on stealth to catch their prey.
0:01:42 > 0:01:46For a surprise attack, tiger sharks use camouflage,
0:01:46 > 0:01:48known as counter shading.
0:01:48 > 0:01:51In the ocean, light from the sun falls from above, and if you
0:01:51 > 0:01:56see the shark from underneath, its light belly blends in with the sky.
0:01:56 > 0:01:59But if you look down on the shark from above,
0:01:59 > 0:02:03you see its dark upper surface against the sea bed below.
0:02:03 > 0:02:07But tiger sharks also ambush their prey at the surface,
0:02:07 > 0:02:10and that's where their stripy pattern comes in.
0:02:10 > 0:02:12It mimics the movement of light on the water,
0:02:12 > 0:02:15breaking up their outline and allowing them
0:02:15 > 0:02:18to get close enough to their prey to launch an attack.
0:02:22 > 0:02:23Camouflage even allows them
0:02:23 > 0:02:27to hunt wary albatross chicks who are learning to fly.
0:02:28 > 0:02:30Almost hidden in the shallows,
0:02:30 > 0:02:34tiger sharks wait for the perfect moment to strike...
0:02:34 > 0:02:36snatching a feathery supper.
0:02:44 > 0:02:48The tiger shark, driven by its voracious appetite,
0:02:48 > 0:02:51armed with bone-crushing jaws
0:02:51 > 0:02:53and using crafty camouflage...
0:02:54 > 0:02:57This is the most ravenous shark in our seas.
