Chinese Pond Turtle

The Chinese Pond Turtle, also called Reeves's Turtle or the Chinese Three-keeled Pond Turtle, is an East Asian freshwater turtle in the family Geoemydidae. Its native range includes China and Korea. Populations in Japan and Taiwan, once regarded as native, are now thought to result from historical introductions. The species can hybridize with other Mauremys turtles, which complicates the identification and management of introduced populations. (Wikipedia, general species account)
