The Mississippi mud turtle is Kinosternon subrubrum hippocrepis, a subspecies of the eastern mud turtle. The species ranges widely across the eastern and southern United States, from New York to Florida and west to Texas and Oklahoma, and three subspecies are recognized: the nominate form, this one and the Florida mud turtle (K. s. steindachneri). This subspecies ranges mainly through the Mississippi River basin, including Louisiana, Texas, eastern Oklahoma, Arkansas, southeastern Missouri, Mississippi, western Tennessee and southeastern Illinois. The species is small, 7.6 to 10.2 cm in carapace length, and often hard to identify. The carapace is keelless and unpatterned, varying from yellowish to black. The large plastron has two hinges and is yellowish to brown, sometimes with a dark pattern. The chin and throat are yellowish grey streaked and mottled with brown, the limbs and tail are greyish, and the iris is yellow with dark clouding. It lives in weedy fresh waters such as rivers, lakes, ponds, ditches and swamps, rarely basks and hibernates by burrowing into mud. In Japan small numbers are sold by specialist shops.
