The Snapping Turtle is probably the most common turtle in Vermont. The carapace (shell covering the back) is shallowly domed with a strongly toothed posterior margin (see photo below). The plastron (shell covering the belly) is narrow, leaving the turtle’s flesh always partially exposed. It is uniformly grayish brown with no colorful markings, spots, or stripes.  It is often covered in algae, giving it the nickname moss back.

The Snapping Turtle can get quite large. The upper shells of adults range from 10-18 inches long. The young have three keels that disappear with age and wear. They have a long tail that has spines along the top. They also have a long neck.

When out of the water Snapping Turtles are defensive. To prevent injury to yourself, you should stay out of reach of their long necks and strong jaws.  When in the water, they try to avoid humans.

How to Help a Snapping Turtle Cross The Road

Lifting the turtle by the base of the hind legs works very well, but many people are wary of trying it.  Snapping Turtles do have a dangerous bite and you should remember that their neck can reach just short of the length of their shells.  Approach the turtle from behind and keep your hands low.  Wrap your hands around the very base of the hind legs with the turtle facing up and away from you (see above photo).  They will resist at first with their very powerful legs and claws, but once your hands are in position, it is an easy and safe way to carry all but the very heaviest turtles.
