spotted turtle

The spotted turtle, the only species of the genus Clemmys, is a small, semi-aquatic turtle. Their broad, smooth, low upper shell, or carapace, reaches 8–12 cm (3.1–4.7 in) upon adulthood, and ranges in its exact colour from black to a bluish black with a number of tiny yellow round spots. The spotting patterning extends from the head, to the neck and out onto the limbs. Sexually mature males have a concave plastron and a long, thick tail. By contrast, sexually mature females possess a flat plastron and have a tail that is noticeably shorter and thinner than that of mature males. Mature males also have a dark iris and face; females typically have a yellow or orange iris and a similarly coloured face that is distinctly lighter than the males'. Juveniles appear female-like in this regard, and at maturity males begin to develop darker features.
