Usage
What’s the difference between crocodiles and alligators? Crocodiles and alligators 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. Crocodiles are often lighter in color and have a narrower snout. Alligators are typically darker and have broader snout. When they’re in the water, crocodiles typically hold the top of their head out of the water. In contrast, alligators typically lurk under the surface, with only their eyes visible. 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. Crocodiles live in tropical areas of Africa, Asia, the Americas, and Australia. Alligators mainly live in the southeastern U. S. and eastern China. The only place that wild alligators and crocodiles have been documented as inhabiting the same area is in south Florida. Taxonomically speaking, crocodiles and alligators are not only different species, they also belong to a different genus (crocodiles belong to the genus Crocodylus, while alligators belong to the genus Alligator). Still, they both belong to the order Crocodylia, which means they can both be called crocodilians. Here’s an example of crocodile and alligator used correctly in a sentence. Example: Florida is known for its population of alligators, although a few crocodiles also live in the extreme south. Want to learn more?

Etymology
Origin of crocodile
1250–1300; < Latin crocodīlus < Greek krokódeilos crocodile, originally a kind of lizard, said to be equivalent to krók ( ē ) pebble + -o- -o- + drîlos, dreîlos worm (though attested only in sense “penis”), with r lost by dissimilation replacing Middle English cocodrille < Medieval Latin cocodrilus
Explanation
A crocodile is an enormous reptile that has a long mouth lined with sharp teeth. Crocodiles live in and out of the water, preying on fish, birds, lizards, and mammals, snapping them between their powerful jaws. Although crocodiles and alligators are related, they're from separate biological families and look slightly different from each other. Crocodiles have narrower heads and more pointed snouts — and even when their mouths are closed, you can still see all 80 of their teeth. They're carnivores that feed on everything from molluscs to large mammals, including buffalo, deer, and wildebeest. Crocodile has a Greek root, krokódilos, or "lizard."
