Jamie heads to the Namib desert to see how animals survive in a desolate, dry environment.
First up is the sidewinder snake, which has evolved to move perfectly up and down the sand dunes at great speed. Jamie then demonstrates how humans have developed their own side-winding in the form of sand boarding. Taking a huge wipe out at the bottom of a dune, Jamie shows that maybe we are not quite so well adapted.
He then discovers how desert elephants find and store huge amounts of water, and how chameleons and bat-eared foxes find food.
Jamie also attempts to find water in the desert like a fog-basking beetle. He makes a contraption very similar to a beetle shell to see how much water he can collect. And finally Jamie investigates the cartwheeling spider, which can cartwheel down a slope at speeds of 44 turns a second. So Jamie creates a human cartwheeling device out of car inner tube and hurls himself down a sand dune.
