The Central American river turtle (Dermatemys mawii), also known locally as the hickatee or tortuga blanca (white turtle), is the only living species in the family Dermatemydidae. Its closest relatives are only known from fossils with some 19 genera described from a worldwide distribution from the Jurassic and Cretaceous. The species is currently found in the Atlantic drainages of Central America, specifically southern Mexico, Belize and Guatemala. It is a relatively large-bodied species, with historical records of 60 cm (24 in) and weights of 22 kg (49 lb); however, more recent records have found few individuals over 14 kg (31 lb) in Mexico or 11 kg (24 lb) in Guatemala.
