Mating behaviour appears to be triggered by rain; in captivity, spraying males with water results in them chasing females and attempting to mount. Nothing is known of nesting behaviour in the wild. One, two, or rarely three eggs are laid per clutch; in captivity, laying usually occurs in the night or early morning. Females produce up to three clutches per year. A plastron hinge develops to ease laying. Three captive incubations have succeeded, with durations of 106, 110, and 145 days.
