is native to Vietnam, Cambodia and in some regions of Myanmar, Laos, Thailand and Malaysia. The Giant Asian pond turtle can be found inhabiting streams, marshes and rice paddies extending from moderate altitudes of up to approximately 1312 feet (400 meters) above sea level to the estuarine lowlands. The giant Asian pond turtle can also be found on a variety of freshwater habitats, including lakes, rivers and swamps which are located from the sea level up to hilly areas. However, the pond turtle species is not restricted only to water habitats, it can also be found partially hidden underneath ground vegetation.
Breeding in the Giant Asian pond turtle species is derived from the observations of individuals in captivity. The Giant Asian pond turtle practices an aggressive mating process which lasts for many hours. The male species usually bites the neck and head of the female species. Upon biting, the male Giant Asian pond turtle mounts the female and tightly grips its shell. After mating, the female Giant Asian pond turtle usually lays approximately four to six clutches of eggs. The eggs take about one hundred days with temperature ranges between 80 to 82 f degrees (27 to 28 degrees Celsius) before they hatch into hatch-lings. Occasionally, the hatch-lings are born with a soft area in the center of its plastron.
The giant Asian pond turtle species is a semi aquatic turtle. They are one of the largest hard-shelled semi-aquatic species. The upper shell, also known as the carapace, has a black or brown to grayish-brown coloration with a well-marked ridge which runs along the center and is highlighted with a pale streak. Adults measure up to 19 inches (48 cm).

The major threat that the giant Asian pond turtle species faces is the increasing, uncontrolled freshwater turtle’s trade in Southeast Asia. Some of the species varieties have been traded, pushing them towards extinction. In other regions like Malaysia, the turtle species makes about fourteen percent of the filed exports of freshwater turtles. The turtle is exploited for subsistence food and medicine. They are also threatened by pollution and drainage of there habitat.
Most researchers work has observed the Giant Asian pond turtle species often feeds on primarily aquatic plants in the wild habitats. However, the turtle varieties which are kept in captivity usually has an omnivorous type of diet.
