Difference Between Alligator and Crocodile: Key Facts You Should Know

 

Knowing the difference between alligator and crocodile holds significance to biologists.

Wildlife fans and explorers consider it important as well. If it's your first encounter with them, you might believe that both are the same animal. 

But several major characteristics distinguish them from one another. You can see them in their physical appearance, behavior, geographic distribution, and habitat.

To help you better grasp these amazing reptiles, let's go through their contrasts. Let's also have a look at these intriguing alligator facts.

Physical Variances: Skins, Teeth, and Snouts

Look at their snout. This is one of the quickest ways of differentiating an alligator from a crocodile.

  • Alligators' snouts are round and broad. Their U-shaped muzzles are wide.

  • Crocodiles have more pointed, V-shaped snouts.

With their mouths shut:

  • The upper jaws of alligators entirely enclose their bottom teeth.

  • The crocodiles' upper and lower teeth are visible. But the fourth tooth on the bottom jaw remains hidden.

Additionally, there are changes in their skin's texture:

  • The skin of alligators is rough and dark.

  • With a rougher appearance, crocodiles may seem lighter and more olive brown.
