Adult carapace length: 3.25 to 5.37 inches (8.3 to 13.6 cm).

Habitat: In Michigan, mostly inhabits clear lakes with sand or marl bottoms.

Habits: Rarely bask, are generally seen foraging along the bottom in shallow water. May be nocturnal in summer. They eat snails, crayfish, insects, tadpoles, etc. If disturbed, glands along lower edge of shell secrete a foul-smelling musk, hence the common name "stinkpot."

Reproduction: Females deposit 2 to 9 elliptical, hard shelled eggs in ground or under shoreline debris. Eggs hatch in late summer or fall. Hatchlings are less than one inch long.

Range and Status: Common in southern Lower Peninsula, but threatened by lakeshore development.
