Big headed turtle platysternum megacephalum
Background
Previously considered a distinct family placed on occasion in "Kinosternoidea", it was later moved to the Emydidae. With the Geoemydidae being split off from these, it seems wisest to reinstate, at least for the time being, the Platysternidae. This, as well as the subfamily and the genus Platysternon, are monotypic.
Distribution
It is found in Cambodia, China, Laos, Myanmar, Thailand, and Vietnam.
Behaviour
The big-headed turtle is known to readily climb over obstacles in and around rivers and fast streams, using its tail as a prop to extend the reach of its strong claws; it also uses its beak to assist in climbing. It has been reported to climb trees and bushes. It is not a strong swimmer, and when swimming, this species occasionally arches its tail in the manner of a scorpion. The big-headed turtle cannot pull its head in its shell. That being the case, it will not hesitate to use its powerful jaws to defend itself. It is a fish and snail eater.
Exploitation
The big-headed turtle is readily consumed in Asia and is frequently a market item. Hunters capture them on lines with baited straight pins, so this species is rapidly disappearing in the wild.
Subspecies
In addition, two other subspecies, P. m. tristernalis (1984) and P. m. vogeli (1969), have been given, but may be invalid.
