  • Aquatic insects and invertebrates, aquatic plants and carrion.


  • Hibernation, under mud or logs, lasts from late October to April.
  • If handled, the Stinkpot Turtle lives up to its name by releasing a musky smelling substance from under its carapace.


  • Mating occurs from April to May, and possibly a second time in the fall.
  • From late May to early July, clutches of 2-5 brittle eggs are laid in a hole dug in sandy soil, or beneath ground cover. Typically muskrat houses are used by the females for nesting sites.
  • Males mature after 3 or 4 years, however females may not mature until they are 7 or older.
  • May live to the age of 50.


  • The main factor in their decline is the draining of wetlands and shoreline development.
