Sexual dimorphism is present within this species, which aids in differentiating between females and males. Females generally grow larger than males, with the females growing to 26cm compared to that of the males at 21cm. The males' plastron is generally more concave, and females' platsron is generally more convex. The males' anal scutes are predominately 'V' shaped, where the females' are predominately 'U' shaped. Also, the males generally have a longer tail.
When these two sexes breed, the female turtle lays her 4-24 eggs in the early Summer. She lays them in the bank of her aquatic habitat, well above the waterline, and buries them in the soil. The eggs are long, pointy, and hard shelled. The incubation period is 3-5 months.
Hatchlings emerge usually after rain has softened the soil above the nesting chamber, to where they scuttle straight to the water. Their colourings differ from the adults by having a red or orange plastron.
Females may have 1 - 3 clutches a year.
