Mauremys reevesii
A geoemydid turtle of East Asia. Three distinct keels run along the carapace and irregular yellow to pale green streaks mark the head. The carapace reaches 30 cm, with females growing larger than males.
Mauremys reevesii is a geoemydid turtle of East Asia and the smallest member of its genus. The carapace is rather flat, with three keels running along the vertebral and costal scutes, the vertebral keel being the most prominent. The head is olive to dark brown with irregular yellow or pale green streaks. The carapace reaches 30 cm and females grow larger, males stopping at 19.9 cm. Adult males turn entirely melanistic, iris included, and lose their markings. It is not a strong swimmer, prefers still water with a gentle flow and basks readily. Scent glands at the base of the limbs release a foul smell when it is attacked, the origin of its Japanese name. Japanese populations have no fossil record and are thought to have been introduced from the Korean peninsula and mainland China. Hybrids with the Japanese pond turtle, known as unkyu, are fertile.

Listed in CITES Appendix III at the request of the People's Republic of China, effective February 17, 2005 (listing country: People's Republic of China). As an Appendix III species, an international endangered species certificate is not required, though import requires a certificate issued by the exporting country. It does not qualify as a designated animal under the Animal Protection and Management Act enforcement regulations, nor is it designated as a specified alien species. It is protected in South Korea, the People's Republic of China, and Taiwan. Individuals resulting from hybridization with the yellow-margined box turtle are designated as specified alien species.

Prepared pellets, small fish, snails, crustaceans and greens
Build a gradient with water at 21-27 C, ambient air at 24-29 C and a basking area at 29-35 C. Temperatures inside an aquarium differ from those in the room, especially under a hood, so check them with a thermometer regularly.
An active turtle that should have as much water as possible: allow at least about 19 litres for a single hatchling and add eight to eleven litres for each additional animal. A basking platform is essential. Females grow large, so the species is unsuitable where a big enclosure cannot be provided.
Omnivorous: build the diet around a purpose-made pellet with small fish and greens alongside. Large individuals crush and eat snails and sizeable crustaceans. Overfeeding fouls the water and leads to obesity.
It tames readily and many individuals will beg for food. It can hybridise with other geoemydids, however, so mixed-species housing is not advised. Hatchlings have delicate skin, so pay close attention to water quality.
Listed on CITES Appendix III at the request of China, effective 17 February 2005. Appendix III species need no individual registration certificate in Japan, but import requires documentation issued by the exporting country. It is neither a designated dangerous animal nor an invasive alien species in Japan. Japanese populations are nonetheless believed to be introduced, and hybridisation with the Japanese pond turtle is a recognised conservation problem; hybrids with the Chinese stripe-necked turtle are themselves designated invasive alien species. Never release or abandon animals outdoors.
Beginner. This is a beginner-friendly species. No special equipment or experience is required, and it can be kept successfully with basic care setup.
The average lifespan of Reeves' Turtle is 10-15 years or more in captivity, with animals exceeding 20 years. With proper care and nutrition, they can live a long and healthy life.
Reeves' Turtle typically reaches Carapace up to 30cm, males up to 19.9cm as an adult. Size may vary depending on care conditions and individual genetics.
Reeves' Turtle feeds on: Prepared pellets, small fish, snails, crustaceans and greens. Aim for a balanced diet with appropriate feeding frequency.
