Pseudemys nelsoni
A large cooter whose plastron is a uniform reddish orange. The carapace reaches 34 cm and its domed shape is thought to make the turtle harder for the American alligator, which shares its range, to swallow.
Pseudemys nelsoni is a cooter of the southeastern United States. Large, with a carapace to 34 cm, it has a domed shell that is highest at the front of the third vertebral scute. The black to dark brown carapace carries narrow yellow or orange bars, and the plastron is a uniform reddish orange that gives the turtle its English and Japanese names. Large animals of both sexes often turn melanistic and lose their markings. Adults are largely herbivorous, feeding mainly on aquatic plants such as duckweed and waterweed, together with algae. They bask readily and are commonly seen on banks and fallen logs. The species nests year round and is known for laying its eggs inside the nest mounds of the American alligator. It has been imported into Japan since the 1950s, and animals in the trade today are mostly captive bred or farmed.

Aquatic turtle pellets, aquatic plants, algae and greens; juveniles also take insects
Aim for a basking surface of about 29 C and a water temperature of about 24 C. Indoors, full-spectrum UVB lighting is essential. In lowland Japan from the Kanto region southwards the species can be kept outdoors, and in cold areas captive animals will hibernate.
Adults are large and need a tank or pond of around 1,100 litres. Juveniles can be kept in a 75-110 litre aquarium filled to about two thirds. Always provide a basking platform big enough for the turtle to stretch out and dry off.
Largely herbivorous: alongside aquatic turtle pellets, offer plenty of aquatic plants and leafy greens. Juveniles are more carnivorous, so give them insects too and raise the proportion of plant food as they grow.
Placid and a strong swimmer. Numbers decline where congeners share the same habitat, so mixing it with other Pseudemys in captivity is best avoided.
Not listed on any CITES appendix, and neither a designated dangerous animal nor an invasive alien species in Japan. The genus was, however, placed on Japan alien species list in 2015 as a species to be prevented from establishing, so animals must never be released or abandoned outdoors.
Intermediate. This is an intermediate-level species. Some prior experience and knowledge of environmental management are recommended.
