A large freshwater turtle known for its combative disposition when out of the water with its powerful beak-like jaws, and highly mobile head and neck. The shell ranges in color from dark brown to tan and can even be black in some individuals. Snapping turtles have characteristic tubercles (protrusions) on their necks and legs. Plastrons (bottom of the shell) of snapping turtles are very small and leave much of the extremities exposed. Snapping turtle necks, legs, and tails have a yellowish color and the head is dark in color.
