Their litters: Of all the species of Blue-tongue Lizards, the Eastern Blue-Tongue Lizard has the largest litters of the smallest young.

They flick their tongue to bring particles into contact with the Jacobson's organ on the roof of their mouth.

With their distinctively coloured tongues, these lizards are a common sight in many Australian backyards. With six different subspecies of Blue-tongue Lizards found around Australia, they make up the group of the largest skinks in the world.

Eastern Blue-tongues have long bodies with short stumpy legs and small claws on their fingers.  While their short legs make a fast get away from predators unlikely, they do have a dramatic defence.  When threatened these lizards will open their large mouths and stick out their broad bright blue tongue which contrasts against the pink of the mouth.  This contrast acts as a warning bluff to predators of the potential dangers of the lizard.

Their quiet nature has meant that they have been a welcome guest in many Australian backyards as well as making very interesting pets.
