In Africa, a caracal catches birds in flight with a 'rocket-propelled' launch; in the Australian outback, a kangaroo's hop locates water in a vast desert; on an English farm, an insect accelerates at 700G with help from a clutch in its crotch; and high above the jungles of Borneo, a leaping snake's unique shape allows it to glide through the air without wings.
