Alligator Snapping Turtle

The alligator snapping turtle is one of the largest freshwater turtle species in the world, native to slow-moving rivers, lakes and swamps of the southeastern United States, and readily identified by its massive, spiked shell, powerful hooked jaws and three prominent ridges running the length of its carapace that give it a distinctly prehistoric appearance. It is a patient ambush predator, spending long periods motionless on the riverbed with its mouth open, wiggling a small pink, worm-like appendage on its tongue to lure curious fish within striking range of its powerful bite. Almost entirely aquatic, it rarely leaves the water except for females digging nests to lay eggs, and it can remain submerged for extended periods by absorbing oxygen through specialized tissue in its throat. Individuals can live for many decades and grow to well over 100 kilograms, making it one of the heaviest freshwater turtles on Earth. Historically overharvested for turtle soup and further reduced by habitat degradation, the species has faced significant population declines and is now protected across much of its range.
