Difference between alligators and crocodiles.

First up, check the snout! Alligators have wide, U-shaped snouts, while crocodiles have sharp, V-shaped ones. Next, teeth. An alligator's teeth is usually hidden when its mouth is closed, while a crocodile's teeth are usually visible. Alligators prefer freshwater while crocodiles prefer saltwater. Neither alligators or crocodiles enjoy being pet. Don't try it!
