Once an endangered species, the American alligator-- like this one in the Ocala National Forest-- now lives in freshwater swamps, marshes, and rivers across much of the southern United States, from North Carolina to Texas. While submerged underwater, the alligator’s ear and nostril flaps close and they activate a specialized third eyelid, known as a nictitating membrane, to safeguard their eyes. With 74 to 80 conical teeth at the ready, the reptiles are able to take on any aquatic prey that comes their way. Younger alligators generally start by feeding on shrimp and insects, but move on to snakes, frogs, fish, and mammals as they mature. Learn more in the Museum’s Hall of Reptiles and Amphibians.
