Mauremys mutica
A semi-aquatic geoemydid turtle with a broad yellow stripe running from behind the eye down the neck. The carapace reaches 20.5 cm. Animals traded in Japan are mostly the Yaeyama subspecies, Mauremys mutica kami.
Mauremys mutica is a geoemydid turtle ranging from southern China through Taiwan and Viet Nam to the Yaeyama Islands of Japan. The carapace is oval seen from above, the vertebral keel is weak and becomes indistinct in large animals, and the specific name mutica, meaning smooth, refers to the unserrated marginal scutes. Its most distinctive feature is the broad yellow stripe running from behind the eye down the neck; the plastron is yellow to yellowish brown with dark blotches. The endemic subspecies M. m. kami occurs on Ishigaki, Iriomote, Hateruma and Yonaguni, and most animals in the Japanese pet trade belong to it. The nominate population established in the Kinki region is thought to have been brought from Taiwan in the 1920s and 1930s. It is semi-aquatic, favouring shallow still water with a muddy bottom and dense aquatic plants, and although nocturnal in the wild it is also active by day in captivity.

Listed in CITES Appendix II, effective February 13, 2003. As an Appendix II species, registration certificates for international rare wildlife are not required. It does not fall under the designated animals listed in the Animal Protection and Management Act Enforcement Order, nor is it designated as a designated invasive species. Individuals resulting from hybridization with Malayan box turtles are designated as invasive species. The subspecies Yaeyama box turtle is listed as Vulnerable (VU) in the Ministry of the Environment Red List.

The species inhabits lowlands and hills in a warm humid climate, and M. m. kami lives on subtropical flatland. Avoid sudden swings in water and air temperature and provide a basking area with a thermal gradient.
Keep it in an aquarium with a generous water area. It is semi-aquatic and juveniles stay in water, but adults also forage on land, so provide a dry land section. For nesting it needs a diggable substrate mimicking the bare ground at a water edge.
Omnivorous, taking fish, tadpoles, insects, small crustaceans, earthworms, leaves, algae and fruit. Most individuals feed readily and take prepared pellets well in captivity.
It is poorly tolerant of company and may bite other animals. Males in particular force copulation on both sexes and on other species, so house it singly as a rule.
Listed on CITES Appendix II; because it is an Appendix II species no individual registration certificate is required in Japan. It is neither a designated dangerous animal under the Act on Welfare and Management of Animals nor an invasive alien species, although hybrids with the Chinese stripe-necked turtle are designated invasive alien species. Escaped and abandoned M. m. kami have been found across Japan and hybridisation with native populations is a recognised genetic concern. Never release or abandon animals outdoors.
Intermediate. This is an intermediate-level species. Some prior experience and knowledge of environmental management are recommended.
The average lifespan of Asian Yellow Pond Turtle is Maximum recorded longevity in captivity is 22 years. With proper care and nutrition, they can live a long and healthy life.
Asian Yellow Pond Turtle typically reaches Carapace up to 20.5cm (19.5cm in the nominate subspecies, 18.9cm in M. m. kami) as an adult. Size may vary depending on care conditions and individual genetics.
Asian Yellow Pond Turtle feeds on: Prepared pellets, fish, tadpoles, insects, small crustaceans, earthworms, leaves, algae and fruit. Aim for a balanced diet with appropriate feeding frequency.
