It is characterised by a dark reddish brown to dark green or black body with orange, reddish brown, green and white spots. There are distinctive cross-like white patches, outlined in blue, around the gill pocket, and between the rhinophores. In one specimen from eastern Australia many of the spots are green rather than orange. It was previously known from western Australia and the Great Barrier Reef.
