Life and Habits

The turtle lives in rivers, lakes and marshes, ponds, reservoirs, and other freshwater areas where the currents are gentle and fish and shrimp thrive. It is also often found in large mountain streams. In the quiet, clean, sunny waterfront activities are more frequent. Prefer to bask in the sun or ride the cool wind.

The hibernation period is from October to March every year, when it dives in the mud and sand under the water. In Baiyangdian, Hebei Province, China, the soft-shelled turtle starts hibernating in late October when the water temperature is 6-8 degrees Celsius, and it hibernates individually or in groups, about 7.5 centimeters into the mud, mostly in the places where Malay eyelet, castor eyelet, and red cabbage are cultivated. When the water temperature reaches 13-15℃ in April, hibernation is lifted.
