The distinguishing character of the species is its shell, which is elongated and tapers to a sharp point posteriorly. The carapace is ridged and leathery and does not show any scutes like structure in adult. The carapace has 7 ridges whereas the plastron bears 5. The whole shell is covered by smooth black skin with black spots. It possesses 2 sharp cusps on the upper jaw that can seize a slippery prey.
