Mark Evans joins experts in anatomy, evolution and behaviour in a bid to get under the skin of the crocodile. Meanwhile evolutionary biologist Professor Richard Dawkins explains how little the crocodile has changed since the age of the dinosaurs. The team uncovers the crocodile's incredible jaw muscles, as biologist Simon Watt travels to Florida to test the huge strength of the massive reptile's bite: the most powerful in the animal kingdom. But while crocodiles' spiked teeth are excellent for gripping prey as they plunge into a death roll, they are useless for chewing. So how do these animals manage to digest large chunks of raw meat and bone? As the experts dissect the digestive system and inspect the stomach contents for clues, they reveal the bizarre plumbing between the heart and the stomach that might provide the key to this puzzle. And they also solve the mystery of this crocodile's premature death. Also the programme reveals that despite its prehistoric appearance, the crocodile's anatomy is far from primitive, it is perfectly evolved to be the ultimate predator.

    Be assured that none were killed for the purposes of the show. The elephants was an older animal from a zoo which had to be euthanised due to severe illness. The whale stranded and died of natural causes.
