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.
