crocodile2

The crocodile family contains 23 species, including alligators, caimans and gavials. All are large reptiles with long bodies and short legs. most crocodiles have wider, U-shaped snouts. The gavial has long slender jaws – just right for catching fish.

In alligators and caimans the teeth of the lower jaw fit into pits in the upper jaw and cannot be seen when the mouth is closed. In crocodiles the fourth tooth on each side of the lower jaw firs into a notch on the upper jaw, so they are always visible. Crocodiles are generally bigger and more aggressive than alligators.
