The Snake-eating Twin-hinged Tortoise lives in ponds and flooded rice fields in China and the Ryukyu Islands.
It is also called the Chinese Box Turtle, but it doesn't swim and is not a true turtle. Like other Asian Box Turtles, it is a terrapin.
It can live in shallow water and it eats frogs and juvenile snakes as well as insects (unlike most true tortoises which are vegetarian).
It can also live on land.
The name "Twin-hinged" refers to hinges on front and back which can be closed to seal "carapace" and "plastron" together with head and limbs inside protected against predators.
Considered a food delicacy, they are now an endangered species.
