About Snapping Turtles in Minnesota

The largest turtle in Minnesota, the Common Snapping Turtle, is widely known due to its widespread distribution and nasty temperament.

Nine species of turtles can be found in Minnesota. None are more widespread or widely known than the common snapping turtle (commonly referred to just as 'snapper'), which also happens to be the largest. The Minnesota Department of Natural Resources considers the common snapping turtle as a species of special concern. They are hunted for their meat year round. While their take is unregulated, a license is required.

Geography

The common snapping turtle occurs throughout the Unites States east of the Rocky Mountains. They are found statewide in Minnesota in almost any semi-permanent body of freshwater. They reach their peak abundance is slow water habitats with mud bottoms and plenty of aquatic vegetation.

Identification

The common snapping turtle can be distinguished from all other Minnesota turtles by its large head, serrated posterior shell margin and a long saw-toothed tail. Common snapping turtles are drab colored and often will be covered by mud and algae, making any attempt at identification by color or pattern pointless.

Size

The average straight-line measurement of the upper shell (the carapace) in Minnesota is 8 to 14 inches, and the average adult weighs between 10 to 35 pounds. The largest specimen known from Minnesota had a carapace length of 19.5 inches and weighed 65 pounds. Male common snapping turtles grow larger than females.

Considerations

Holding a large common snapping turtle by its tail isn't a recommend way to handle them. While it may be safe to you, there is a risk of damaging the turtle's tail vertebrate and associated ligaments. A safer means to handle one is to grasp the hind legs securely near the shell and hold them away from your body.

Warning

A common snapping turtle removed from its wetland home will eagerly demonstrate how it got its name. The will repeatedly lunge with their mouth open, even if you are well out of reach. They are quite capable of delivering a bite that is both painful and potentially damaging should you get too close.
