Spotted turtles are named for the round yellow spots found on the turtle’s carapace. The rest of the smooth carapace is dark brown or black in color. The head is black with yellow splotches often found on each side with scattered yellow spots. The legs are also black with scattered spots. The turtle’s plastron has a splotchy pattern of black and yellow or orange. There is sexual dimorphism found between the males and females. Male spotted turtles have a concave plastron, while the female’s is flat. Their carapace is more compressed and extended than the females, which is higher and more rounded. Eye color also varies as the male’s eyes are brown and the female’s are orange. The female’s chin is yellow or orange in contrast to the tan, brown, or black of the male’s. There is also a difference in their tails. His tail is generally longer with his vent placed beyond the edge of the carapace when his tail is extended. Her tail is narrow, and with it completely extended, her vent is at or beneath the edge of the carapace.
