How to tell the difference between a crocodile and an alligator
Look at the snout.
The easiest way to tell the difference between crocodiles and alligators is to look at their snouts. Alligators have a wide, rounded, " u "-shaped snouts with larger noses, whereas crocodiles have longer, thinner, pointed " v "-shaped snouts and smaller noses.
Alligator snouts are also shorter than crocodile snouts. The broad snouts that alligators have give them more strength than crocodiles.
