Lamington Crayfish (Euastacus sulcatus)

The Lamington Crayfish is a freshwater crayfish, or “yabby”. It is bright blue in colour and roams the forest floor when conditions are damp. E. sulcatus ranged from Mount Tamborine to the Lamington Plateau, southern Queensland, and west along the McPherson Range bordering New South Wales.
