Even though they are distinct creatures (both belong to the order Crocodilia but not the same family), many people remain curious about how to tell crocodiles and alligators apart. They may seem quite similar at first glance. To those who aren't familiar with them, both appear as ancient reptiles from the swamps. However, there are simple tricks to help you avoid a mistake the next time you're in Florida.
The fastest way to distinguish between the two is by examining their smile: Both animals have long teeth on either side of their lower jaws. When crocodiles close their mouths, these teeth remain visible, sticking out from their faces. Alligators, however, tuck them into sockets in their upper jaws. Generally, the more prominent the teeth, the more likely you're looking at a crocodile.
You can also check their head shape and skin color. Crocodiles typically have a V-shaped snout, while alligators have a shorter, U-shaped one. Alligators also feature darker, greener skin, unlike crocodiles, which tend to have a lighter, tan or brown hue.
Geographically speaking, crocodiles are far more widespread, found throughout much of the eastern hemisphere and Central America. Alligators, on the other hand, have a more limited distribution, mainly residing in South America and the southern U.S., with a small population in China.
There are 23 different species of crocodilians, meaning plenty of variation to consider. When identifying your large reptile, the tooth rule is crucial. Like sharks, crocodiles and alligators are capable of regrowing their teeth, so those sharp, telltale teeth are likely to always be visible.
