The Ganges Soft-shelled Turtle "Aspideretes gangeticus" is a species of softshell turtle found in South Asia in rivers such as the Ganges, Indus and Mahanadi.

Description

Costal plates eight pairs, the last well developed and in contact throughout on the median line; two neurals between the first pair of costals; plates coarsely pitted and vermieulate. Epiplastra narrowly separated from each other in front of the ontoplastron, which forms an obtuse or a right angle; plastral callosities very large, hyo-hypoplastral, xiphiplastral, and, in old specimens, ento-plastral. Dorsal skin of young with longitudinal ridges of small tubercles. Head moderate; snout (on the skull) about as long as the diameter of the orbit; interorbital region, in the adult, considerably narrower than the nasal fossa; postorbital arch one third to one half the greatest diameter of the orbit; mandible with the inner edge strongly raised, forming a sharp ridge, which sends off a short perpendicular process at the symphysis; the diameter of the mandible at the symphysis does not exceed the diameter of the orbit. Olive above; back of young vermiculated with fine black lines, but without ocelli; head with a black longitudinal streak from between the eyes to the nape, intersected by two or three inverted-V shaped black streaks; lower parts yellowish.Length of dorsal disk 2 feet.
