There are only two species of true alligators in the world, the American Alligator (Alligator mississippiensis) and the endangered Chinese Alligator (Alligator sinensis).

Compared to crocodiles, alligators have a rounder and wider “U” shaped snout. Also, when the alligator’s jaw is closed, the fourth bottom tooth cannot be seen.

Most alligators prefer to live in fresh water.
