Revered for their unmatched strength and respected for their tenacity, alligators and crocodiles are among the most impressive reptiles on the planet!
Not only are these some of the largest living reptile species, they’re also among the oldest. Crocodilians originated more than 200 million years ago. With their scaly, armored bodies, sharp teeth and massive tails, they resemble the dinosaur relatives they outlived.
But how will you tell our closely related reptile species apart? The answer is right on the nose! Crocodiles have a long, narrow snout while alligators sport a broad, shovel-shaped snout.
American alligator and Orinoco crocodile
Alligators have broad, u-shaped snouts. Also, their bottom teeth fit neatly into upper jaw sockets, so only an alligator’s top teeth show with closed jaws.
American alligators are the largest reptile native to the U.S. Once on the brink of extinction, courageous conservation efforts has brought this species roaring back.
Alligators are the most cold-tolerant of the crocodilians and can be found in our heated outdoor pool year-round!
A crocodile has a snout that's long and narrow. They also show off all their fierce teeth when their jaws are closed.
Found in rivers in a small part of South America, Orinoco crocodiles are among the largest predators on the continent. The species is critically endangered due to habitat loss and pollution. You can support Orinoco crocodile conservation by participating in our 2021 Round Up for Conservation at our Gift Shop.
