Alligator snapping turtles are sometimes described as dinosaur-like because of their spiky shells and primitive-looking faces. They have three pointed ridges along their shells that run from head to tail. Unlike all other species of snapping turtle, this one has eyes on the sides of its head. Alligator snapping turtle is the largest species of freshwater turtle. Males typically weigh between 155 and 175 pounds (70 and 80 kilograms). It is said that a 400-pound (180-kilogram) alligator snapping turtle was caught in Kansas in 1937, but there isn’t sufficient evidence to confirm the claim.
Alligator snapping turtles are found exclusively in the United States, from northern Florida to eastern Texas and as far north as Iowa.
