The Common Snapping Turtle (Chelydra serpentina) is a large freshwater turtle of the family Chelydridae. Its natural range extends from southeastern Canada south, west to the Rocky Mountains (and beyond, where introduced), throughout Mexico, and as far south as Ecuador. This species and the larger Alligator Snapping Turtle are both widely referred to as snapping turtles or snappers (though the Common Snapping Turtle, as its name implies, is much more widespread overall).
