Desc: Speed Kills Desert: Directed by Graeme Duane, Richard Slater-Jones. Desert creatures endure searing heat and zero rainfall, but speed is their ticket to survival. A Tiger beetle runs at the human equivalent of 500 miles per hour. A caracal jumps six feet to swat a weaverbird out of midair. And the world's fastest chameleon hunts on the desert floor. Only the hardiest, fastest animals survive. Nothing else stands a chance.
