The Common Snapping Turtle is a freshwater turtle that can be found in areas from southeastern Canada, to the southwest edge of the Rocky Mountains, in Nova Scotia to the east, south into Florida and into northeastern Mexico. The Common Snapping Turtle is one of two of the species found in North America. Common Snapping Turtles have ridged carapaces (upper shell) which at maturity can measure up to 20 inches in length. They are known for their powerful jaws, and mobile heads and necks which resemble a snake (the word serpentina means "snake-like"). Their weight can average from 10 to 35 pounds. The heaviest wild Common Snapping Turtle caught weighed 75 pounds.
