The primary difference between a crocodile and an alligator is their size. Crocodiles can be up to 6 meters (20 feet) in length, while alligators typically range from 3-4 meters (10-13 feet). Crocodiles have more rounded snouts than alligators, which helps them better maneuver through tight spaces such as rivers and lakes. Alligators tend to be more aggressive and territorial than crocodiles, often attacking humans if they feel threatened.
