Just above water
The American Alligator is endemic to the southeastern United States from Texas to North Carolina and lives in a variety of wetland habitats. Alligators hunt by swimming surreptitiously underwater, often with only their nose and eyes above water to breath and see their prey. Terrestrial prey often don't notice the alligator until it's too late.
The American Alligator is one of the big success stories of the Endangered Species Act in the United States. Historically hunting had reduced their numbers so low that they were listed as endangered. Since the Endangered Species Act was passed in 1973, conservation efforts have helped the species recover from low numbers that it was de-listed in 1987.
