The keeled box turtle (Cuora mouhotii syn. Pyxidea mouhotii) is a species of turtle in the family Geoemydidae. The species is endemic to Asia.
Other common names for C. mouhotii include keel-backed terrapin, jagged-shelled turtle, and Mouhot’s turtle.
The keeled box turtle’s upper shell (carapace) has three large, raised ridges and is serrated on the back end. The lower shell (plastron) is different variations of brown in color, ranging from light brown to dark brown. The upper jaw is strong, while the snout is short and curved. The feet are only partially webbed, which suggest a terrestrial lifestyle as opposed to an aquatic one.
Male and female keeled box turtles can be distinguished by the color of their eyes as well as their nails. A male generally has longer and thicker nails than a female, and eyes that are either black or brown. A female generally has shorter, thinner nails, and eyes that are orange or red.
In China the species is bred in captivity on a small scale for the pet trade.
