There is a creature that once walked the earth with dinosaurs... a creature that spent 135 million years adapting into one of the world's most brilliant killing machines... a creature that more than lives up the deadly reputation it has...
...a crocodile!

This is a Nile Crocodile and when fully grown, it could reach up to 6m in length.
He may look slow moving and clumsy, but rest assured that crocodiles can really shift!
You might have heard the expressions "crocodile smile" or "crocodile tears" - but have you ever heard of the crocodile death roll?

It originated because of the way crocodiles kill. They have a special technique for ripping chunks off their prey.
They take a big bite, hang on tight and then spin around and around, ripping chunks of meat off the victim!

To put it to the test, we used a dwarf crocodile. This one is smaller than the nile crocodile but could still rip a human hand off with great ease.
To conduct the test we put a piece of meat onto the end of a short piece of rope. Stephen carefully dangled the rope with the meat in the crocodile's tank.

And then, sure enough, the crocodile grabbed it and started to spin, tearing ferociously at the meat!
There you have it - the crocodile death roll.
