Common Snapping Turtle

Scientific Name

Chelydra serpentina

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.

Diet

Snapping turtles are omnivores and opportunistic feeders. They feed on carrion, invertebrates, fish, birds, small mammals, amphibians, and a surprisingly large amount of aquatic vegetation.

Behavior

Snapping turtles are not social creatures. Social interactions are limited to aggressive interactions between individuals, usually males. Many individuals can be found within a small range; snapping turtle density is normally related to the amount of available food. Snapping turtles can be very vicious when removed from the water, but they become docile when placed back into the water. Snapping turtles sometimes bury themselves in mud with only their nostrils and eyes exposed. This burying behavior is used as a means of ambushing prey.
