Description: Females are larger than males, with a carapace length of 16.5-35.6cm compared to 11.4-17.8cm in males. Females and males also differ in colour. The carapace of adult females is tan or brown with irregular dark brown blotches, while the carapace of males and juveniles is brown or greyish with scattered, small dark brown dots or dashes.
Habitat: It prefers large, unpolluted rivers with sandy substrates. It can also be found in lakes, impoundments, and shallow bogs.
Breeding: They begin mating from the age of 8-10 years. They mate in mid to late spring in deep water. The male nudges the female’s head while swimming, and if she chooses to mate, the male swims above the female without clasping her with his claws (unlike other turtles). The female lays her eggs on a sunny sandbar or gravel bank in a flask-shaped cavity that she digs close to the water.
