The yellow pond turtle (Mauremys mutica), is a medium-sized (to 19.5 cm), semi-aquatic turtle in the family Geoemydidae. This species has a characteristic broad yellow stripe extending behind the eye and down the neck; the carapace ranges in color from grayish brown to brown and the plastron is yellow or orange with black blotches along the outer edges.[2] It is found in East Asia, ranging from central Vietnam, north through the coastal provinces of south and central China. Additional insular populations are found in Taiwan, Hainan, Ryukyu Islands, and Japan.[3] The Japanese populations are believed to have been introduced as a result of imports from Taiwan.[4]

This species inhabits ponds, creeks, swamps, marshes and other bodies of shallow, slow-moving water. It is omnivorous, feeding on insects, fish, tadpoles, and vegetable matter such as leaves and seeds. The yellow pond turtle generally remains in or close to water during the day but may become more active at night and during rainy weather, when it sometimes ventures onto land.[4]

One subspecies, Mauremys mutica kami, is currently recognized in the Ryukyu Islands.[4] Research has shown unexpected genetic diversity in M. mutica, raising the possibility that additional subspecies might exist. Evidence of widespread hybridization further complicates efforts to understand the genetics of this and related species.[5] Several hybrid Asian pond turtles that were described as new species have been found to be hybrids. Fujian pond turtles (Mauremys iversoni) are hybrid specimens mainly produced in Chinese turtle farms, usually from matings between female yellow pond turtles and golden coin turtles (Cuora trifasciata) males. The supposed Mauremys pritchardi turtles are wild and captive-bred hybrids between the present species and the Chinese pond turtle (Chinemys reevesi).[6][7]

The yellow pond turtle is threatened with extinction. China is the largest consumer of turtles in the world and this trade has been cited as the greatest threat to Asian turtles including M. mutica. Most of the turtle trade is destined for human consumption but traditional medicine[8] and the pet trade are also driving demand for turtles.[9][10][11] Habit loss and water pollution are additional impacts. The IUCN considers M. mutica an endangered species and it is listed in CITES Appendix II.[3]
