Clemmys is a genus of turtle, consisting of one North American species, the spotted turtle (C. guttata). "Clemmys guangxiensis" is a composite taxon described from specimens of Mauremys mutica and the natural hybrid "Mauremys" × iversoni. The spotted turtle is declining throughout eastern Northern America due to habitat loss and poaching. From this study, most specifically on the Southeastern population, females had greater shell heights, heavier body masses, and longer plastrons than males.
