A Startling Display: Why the Blue Tongue?
When threatened, the skink opens its mouth wide, hisses and flashes its tongue. The bright color and contrasting pink mouth may startle predators and give the lizard time to escape.
Live Birth
Female blue-tongues give birth to live young, which develop in eggs retained in the body, an arrangement known as ovoviviparity. Litters can contain up to about two dozen babies.
Omnivorous Diet
The lizard eats snails, insects, fruit and flowers, and often helps gardeners by eating slugs. Its smooth, shiny scales are typical of skinks.
