Description
The spotted turtle is one of North America’s smallest turtle species, averaging 8.0–12.5 cm (3–5 in) in carapace length. This cryptic species is named for the bright yellow circular spots that dot its smooth, keelless black carapace (upper shell). The number of spots varies significantly among individuals, and these unique patterns can help identify individual turtles.
Hatchlings generally have one spot per scute (keratinous scales that cover the shell), although some may lack spots altogether. In adult turtles, the spots may be sparse or absent entirely, and individuals may be stained with tannins or iron oxide. The plastron (bottom shell) is creamy yellow with dark blotches along its edges. The skin is usually gray to black, with occasional yellow or orange spots on the head, neck, and limbs. The undersides of the limbs and other soft parts can appear in shades of pink, orange, or salmon-red.
