The giant Asian pond turtle (Heosemys grandis) inhabits rivers, streams, marshes, and rice paddies from estuarine lowlands to moderate altitudes (up to about 400 metres (1,300 ft)) throughout Cambodia and Vietnam and in parts of Laos, Malaysia, Myanmar and Thailand.

[6] Capable of living in water or on land the giant Asian pond turtle can be located along bodies of water such as lakes, ponds, rivers, streams, and canals.

The giant Asian pond turtle is omnivorous and finds food in both aquatic and terrestrial environments.

Their diets consist of worms, larvae, insects, snails, deceased animals, and aquatic and terrestrial plants.

[8] The main area of concern is the illegal capture and export of these turtles for use as food and (less commonly) as pets in parts of Asia.
