Cocodrils are large reptiles covered in bony plates on their backs and tails and scales on their sides. They have short legs with webbed digits and powerful jaws and sharp teeth used to catch and hold prey without chewing. Cocodrils live in rivers, lakes, swamps and other freshwater and saltwater habitats in warm countries, preying on various animals and even humans by ambushing them at water's edge. Females lay between 20 to 60 eggs which they bury and guard until hatching.
