Sacalia

Sacalia is a genus of turtles in the family Geoemydidae (formerly called Bataguridae). The genus was erected by John Edward Gray in 1870. The Sacalia is native to Southereastern China, Laos, and Vietnam. It was declared an endangered species of turtle by the IUCN Red List due to its illegal trade.[2] The sacalia has a carapace of dark-brown color that permits it to camouflage to its habitat. They are believed to select the area of a river that better matches their color.[3]
