Snapping Turtle

(Chelydra serpentina)

Snapping turtle

Snapping turtles can be easily distinguished from other species because of their large size, massive head, and long tail. Turtles are vulnerable while on land, especially when road crossings are necessary. Unlike many other turtles, snapping turtles can’t pull their head and limbs completely inside their protective shell. Therefore, when encountered on land, snapping turtles may react defensively and snap their powerful jaws. While in aquatic habitats, snapping turtles usually go undetected and can escape without the necessity of a defensive snap.©Charles H. Warren, courtesy of life.nbii.gov

Snapping turtles are long-lived and are known to live in some habitats that may have excessive nutrient loads or pollutants. As a result, snapping turtles are likely to accumulate large levels of toxins within their body tissues. © Mike Marchand Photo
