Characteristic         

It is a forest floor dweller. The attractive juveniles have a carapace which is heavily serrated at the margin, but in adults this feature is reduced to small serrations only on the rear margin of the carapace. The heads of both adults and juveniles bear a distinctive arrangement of reddish spots and blotches on the snout and behind the eye. Adults can be identified by the reddish, or sometimes yellowish, markings on the head and neck and the reddish spot behind the eye. Juveniles and adults have a vertebral keel along the back of the carapace. Their plastral scute has radiating black lines on the upper and middle suture.
