Description

The Australian thornback skate is a skate (Rajidae) of the continental slope in the waters around Tasmania in southern Australia. The species grows to about 55 cm and has a flat, diamond-shaped disc with a pointed snout and a prickly back and tail. As a bottom-dweller of the cold deep water it lies on sand and mud and searches for crustaceans, molluscs and bottom fish. It reproduces with egg cases ('mermaid's purses').
