Alligators are large, semi-aquatic reptiles in the genus Alligator (family Alligatoridae), closely related to crocodiles and caimans. They are carnivorous apex predators found in freshwater habitats such as swamps, lakes, rivers, and marshes. Alligators have armored skin with bony plates (osteoderms), webbed feet, and powerful tails for swimming and defense. Their eyes, ears, and nostrils are positioned on top of their heads, allowing them to stay mostly submerged while keeping their senses alert. In the wild, alligators live about 50 years, with some reaching 70 in captivity. They can survive in temperate climates, unlike most other crocodilians, and often dig burrows to escape extreme weather
