The Australian angelshark ia a common but little-known angelshark found on the continental shelf and uppermost slope, on or near the bottom. It has greatly enlarged pectoral fins with broad triangular lobes extending forward from their bases on either side of the gill slits. The pelvic fins are enlarged and wing-like, and the caudal fin is very short. The head is flat or convex between the eyes and the spiracles are small. Enlarged denticles on the snout, head, and multiple rows on the back ahead of the first dorsal fin, are lost in adults.
