Alligator Vs. Crocodile

What’s the difference between alligators and crocodiles?

Alligators and crocodiles are both large, lizardlike reptiles known for their large, powerful jaws and sharp teeth, their long tails, and their thick, plated skin.

However, you can tell them apart through some physical differences. Alligators are typically darker and have broader snout. Crocodiles are often lighter in color and have a narrower snout.

When they’re in the water, alligators typically lurk under the surface, with only their eyes visible. In contrast, crocodiles typically hold the top of their head out of the water. When alligators’ jaws are closed, only their upper teeth are visible, but both the upper and lower teeth of crocodiles are visible when their jaws are closed.

Alligators mainly live in the southeastern U.S. and eastern China. Crocodiles live in tropical areas of Africa, Asia, the Americas, and Australia. The only place that wild alligators and crocodiles have been documented as inhabiting the same area is in south Florida.

Taxonomically speaking, alligators and crocodiles are not only different species, they also belong to a different genus (alligators belong to the genus Alligator, while crocodiles belong to the genus Crocodylus). Still, they both belong to the order Crocodylia, which means they can both be called crocodilians.

Here’s an example of alligator and crocodile used correctly in a sentence.

Example: Florida is known for its population of alligators, although a few crocodiles also live in the extreme south.
