Snapping turtle

The Snapping Turtle (Chelydra serpentina), or more formally referred to as Common Snapping Turtle when distinguishing them from their larger cousins (Macrochelys), and are popularly nicknamed "snappers". They are large freshwater turtles of the family Chelydridae, ranging from southeastern Canada west to the Rocky Mountains (and beyond, where introduced), and south through Mexico to Ecuador.

Common snappers are noted for their pugnacious dispositions when out of the water, their powerful beak-like jaws and their highly mobile head and neck (hence the specific name "serpentina," meaning "snake-like"). In some areas they are hunted heavily for their meat, a popular ingredient in turtle soup. Common snappers have lived for up to 39 years in captivity, while the lifespan of wild individuals is estimated to be around 30 years.
