River Terrapin (Tutong)

The River Terrapin (Batagur baska), also known as the Tutong, is one of the world's most critically endangered freshwater turtles. Reaching impressive shell lengths of up to 2 feet, these aquatic giants inhabit the estuaries and creeks of India, Indonesia, Bangladesh, and Malaysia, having already been driven to extinction in much of their former Southeast Asian range.
