Eastern Blue-tongued Skinks measure an average of 17 inches long, with a maximum of 22 inches. Their average weight is 10-18 ounces.



In the wild, blue-tongued skinks are omnivores that eat a variety of plants and animals including insects, snails, flowers, fruits, and berries. At Cosley Zoo, the skinks are fed fruits, vegetables, crickets, worms, and mice.


Blue-tongued skinks breed in the spring. Gestation is 150 days. Females give birth to an average of 10 live young at a time, with a maximum clutch size of 25. There is no parental care, and the young skinks are on their own soon after birth. The young grow very quickly and can reach adult size in less than one year.
