Two species of stonefishes are recorded from Australia, the Reef Stonefish and the Estuarine Stonefish and the Reef Stonefish, Synanceia verrucosa. One of the ways to tell the two species apart is the placement of the eyes. The eyes of the Estuarine Stonefish are are elevated and separated by a bony ridge; those of the Estuarine Stonefish are separated by a deep depression.
