I've always wondered what the difference between the crocodile and the alligator is. Can you tell me?

The main difference between a crocodile and an alligator is that crocodiles have more prominent ridges along their snout, while alligators do not. Crocodiles also typically have longer, thicker tails than alligators, which helps them swim faster and maneuver better. Alligators tend to be larger overall than crocodiles, with some individuals growing up to 20 feet long in length.
