This turtle begins hibernation in the fall when the water temperature falls to about 6 to 13 degrees Celsius. It hibernates in mud or trash either in or near the water. It emerges from hibernation in very early spring. This is a timid turtle, hiding in the water or closing into its shell when on land. It is most active in the morning, either feeding or basking. During the night it sleeps in underwater vegetation. It also likes to wander overland.
Mating takes place from March to October (any time it is not hibernating). Males and females both do not become sexually mature until in their teens, but from that point on are sexually active until they die. The female will usually lay one clutch of eggs per year in a soft ground-based nest. The sex of egg embryos is temperature dependent. Males are produced at incubation temperatures of 23 to 26 degrees Celsius, while females are produced at 30 to 31 degrees Celsius. In the middle of the range both sexes are created.
Gestation: Incubation: 50 to 80 days, depending on temperature
Litter: Clutch: 3 to 27 eggs
Conservation Status: Endangered
