Crocodiles : Under the Skin

Saltwater crocodiles. They can grow over twenty feet long ... and weigh well over a ton! They're the biggest and most dangerous reptile on the planet. They can take down a fully-grown buffalo. Smash the shell of a massive turtle. And just as easily snatch a low-flying bird from the air. Crocodiles kill more humans every year than any other predator on earth...including the great white shark. They're one of the most successful predators the world has ever seen. A 100 million year-old biological design, perfectly engineered for the modern world. But how can a creature this primitive still be state-of-the-art? The answer lies beneath its skin - and that's exactly where EXPLORER takes you. A rare dissection opens up the inner workings of this bio-engineered machine. The saltie's weaponry: perhaps the most powerful jaws since T-Rex. Its early warning system: built-in pressure detectors that allow this huge beast to strike in an eye-blink. Multi-tasking organs that give the croc a killer edge. The most complex heart in the animal kingdom. Skin actually creates a 'cloak' of low-pressure - the same basic design employed by golf balls, sports cars and stealth bombers to reduce air resistance and drag! And one of biology's greatest mysteries - was the crocodile once warm-blooded, like us? On CROCODILES: UNDER THE SKIN you'll witness the extraordinary facts behind a creature we once dismissed as a primitive monster.
