Description: This is a small to medium-sized Chelid turtle with a long neck, moderately deep body-form and with only 4 claws on each forelimb. The head is moderately depressed, and the snout is blunt and the eyes tend to be laterally directed. In mature specimens the colouration varies somewhat depending upon location. The carapace may be brown to black and with or without brownish or blackish speckling. The ventral surface may be creamish or whitish, with the sutures of the plastral plates edged in black to a varying extent. Some other significant features of this species' morphology are: gular shields in contact in front of the intergular; inguinal musk glands present; plastron greatly expanded anteriorly, with the anterior lobes of the plastron rounded and not extending laterally any further than the inner edges of the marginals; intergular at least twice, or more than twice the length of the pectoral suture. Generally, the carapace is strongly convex, has a distinct vertebral groove and is more 'crinkled' or irregularly sculptured in surface pattern. The carapace is oval-shaped with some posterior expansion, but there is notable variation in shell shape from one area to another (after WELLS 2007).
Habitat: freshwater (rivers, swamps)
