The alligator snapping turtle (Macrochelys temminckii) is one of the largest freshwater turtles in the world. It is not closely related to, but is often associated with, the common snapping turtle. The alligator snapping turtle is characterized by a large, heavy head, and a long, thick shell with three dorsal ridges of large scales (osteoderms) giving it a primitive appearance reminiscent of some of the plated dinosaurs.
The largest freshwater turtle in North America, the alligator snapping turtle is found primarily in southeasten United States waters.
This alligator snapping turtle was in a reptile park in South Africa. Never seen one till that day.
