Common Bluetongue

Tiliqua scincoides

Also known as Eastern Blue-tongued Lizard, Northern Blue-tongued Skink, Blue-tongued Skink

Common bluetongues are robust, ground-dwelling skinks famous for their vivid cobalt-blue tongues, which they flash alongside a dramatic hiss to startle potential predators. They spend their days basking on warm rocks or slow-foraging through leaf litter, relying on powerful jaws to crush hard-shelled snails and beetles. These gentle omnivores have adapted remarkably well to suburban backyards, where they provide natural pest control around gardens and rockeries.

Why interaction risk is low
Delivers a painful, crushing bite if handled; observe calmly without cornering or picking up.
Why it is dangerous
Possesses exceptionally strong jaw-closing muscles evolved to crush hard shells, capable of causing deep bruising, lacerations, or broken skin.
How to recognize a risky encounter
Recognized by its heavy, sausage-shaped torso, short legs, banded grey or brown scales, and vivid blue tongue displayed inside a wide pink mouth.
What to do
Allow the lizard an escape route into mulch or beneath rocks, and never attempt to pick it up or restrict its movement.
Responsible observation
  • Garden safety: Avoid chemical snail baits in your garden, as ingested poisoned snails can be lethal to visiting lizards.
  • Basking etiquette: Watch them from a few paces back; if approached too quickly, they will flatten their bodies and display defensively.
