alligator and crocodile Alligators (bottom left) have a broad and rounded snout. Crocodiles (top right) have a narrow pointed snout.

A crocodile's fourth tooth on the lower jaw is visible when its mouth is closed. Alligators don't have a protruding fourth tooth and when an alligators mouth is closed, usually only the upper teeth show.
