Dont know an alligator, or gator, from a crocodile? You're probably not alone. Although these large reptiles belong to different families, they share many similarities, including long snouts, powerful tails, short legs, and bony-plated backs.However, there are few easy ways to tell them apart. The first is the shape of the snout. Alligators have broad and U-shaped snouts, while crocodiles' are narrow and V-shaped. Next are the teeth. In the case of alligators, the lower teeth are typically not visible when the mouth is shut. In crocodiles, however, same teeth in the bottom jaw appear, most notably the large fourth tooth. Another difference is color. Gray or black? It's probably an alligator. Olive or tan? A crocodile. The two reptiles also differ in location. Crocodiles are usually found in saltwater habitats, while alligators prefer freshwater areas. And last-but not least-is behavior. Crocodiles are typically more aggressive than gators.
