The Trionychidae are a taxonomic family of a number of turtle genera, commonly known as softshell turtles. The family was erected by Leopold Fitzinger in 1826. Softshells include some of the world's largest freshwater turtles, though many can adapt to living in highly brackish areas. Members of this family occur in Africa, Asia, and North America, with extinct species known from Australia. Most species have traditionally been included in the genus Trionyx, but the vast majority have since been moved to other genera. Among these are the North American Apalone softshells that were placed in Trionyx until 1987.
The Indian narrow-headed softshell turtle, also known as the small-headed softshell turtle or the Indo-Gangetic softshell turtle, is an endangered species of softshell turtle native to waterways and rivers of the Indian subcontinent. It is very large, feeding on fish, frogs, worms, crustaceans and molluscs, and even the occasional swimming small rodent or other mammal. C. indica, like other softshell turtles, uses it flexible shell to dig itself deep into sandy lake and river bottoms; here, it patiently waits for potential prey to swim by. They will also ambush and chase their prey, depending on availability, the time of year, and size of the prey. In the past it was included as a subspecies of Chitra chitra, a species restricted to Southeast Asia using current taxonomy.
The Asian giant softshell turtle, also known commonly as Cantor's giant softshell turtle and the frog-faced softshell turtle, is a species of freshwater turtle in the family Trionychidae.
