The broad-headed skink, which grows from six to 12 inches long, is the largest lizard in Ohio. The female and young closely resemble the female and young of the five-lined skink. Young specimens even have a bright blue tail. Large males become a uniform olive-brown and have considerable red coloration on the head. The back of the head is greatly enlarged. This skink is essentially a woodland inhabitant. It is found only in several counties in the southern half of the state and is rare even there. Occasionally, broad-headed skinks can be observed high in the branches of dead trees. It has the distinction of being the most arboreal of our four species of skinks. LENGTH: 6.5”–12.75”
