Eastern Blue-tongued Skink (Tiliqua scincoides) in the wild — Catch'Um species field guide

Eastern Blue-tongued Skink (Tiliqua scincoides) wildlife photograph

Overview

Eastern blue-tongued skinks are large, slow-moving lizards with bold bands and a startling cobalt tongue flashed as a bluff. They waddle through leaf litter and suburban gardens hunting snails, insects, and soft plant matter.

For Australia collectors, the blue-tongue is a common backyard classic — thick-bodied, tongue-flash defence, and a favourite find under timber and compost.
