Crocodiles have long, narrow, V-shaped snouts, while those of alligators are wider and U-shaped. Crocodiles and alligators are also found in different locations around the globe.

Alligators are native in the eastern section of China and the southern area of the United States, and are most common in states along the Gulf Coast.
