The spotted turtle (Clemmys guttata), the only extant species of Clemmys, is a small, semi-aquatic turtle that reaches a carapace length of 8–12 cm (3.1–4.7 in) upon adulthood. Their broad, smooth, low dark-colored upper shell, or carapace, ranges in its exact colour from black to a bluish black with a number of yellow tiny round spots. The spotting patterning extends from the head, to the neck and out onto the limbs. Males and females can be distinguished by differences in plastron shape and eye and chin colouration.
