Impressed tortoise

Thai: เต่าเดือย, dtao deuay

Binomial name: Manouria impressa, Albert Charles Lewis Günther, 1882

The impressed tortoise (Manouria impressa), occurs in mountainous forest areas in Southeast Asia in Burma, southern China, Thailand, Laos, Vietnam, Cambodia and Malaysia. The species has a golden brown shell and skin. Adults are much smaller than their relatives the Asian forest tortoise (Manouria emys), with a maximum size of 35 cm.

The impressed tortoise lives at high elevations, up to 2, 000 m. Its behavior is little known; diet in the wild may consist largely of mushrooms, although bamboo shoots are also eaten. The species is known for being difficult to keep alive in captivity; although its status in the wild is uncertain, it is eaten widely by local people and little captive breeding has occurred.
