When the time comes to attack, the crocodile explodes from below the surface in a whirl of teeth and spray, moving faster than the human eye can follow. If need be they can jump and stretch to take prey two metres above the surface, and is quick enough to catch a bird in flight, striking as quickly and as deadly as those other reptiles, the snakes.
The crocodile is related to the dinosaurs, and once shared the world with them. Now they are a remnant from a bygone age but remains one of nature's most effective amphibious designs for land and water.
