The Sharptail Sunfish has teeth in both jaws fused into beak-like plates. The species resembles the Ocean Sunfish and the Southern Ocean Sunfish, but can be distinguished by the median projection from the clavus.
The Sharptail Sunfish has a deep compressed body with the dorsal and anal fins positioned posteriorly. The teeth in both jaws are fused into beak-like plates. Adults are uniform brown or greyish. Larvae are blue above and white below.
There is still much to learn about the distribution of the Sharptail Sunfish. It probably occurs worldwide in temperate and tropical marine waters. In Australia it has been recorded in the literature from eastern South Australia to south-western Western Australia. The fish in the lower images was caught in the Coral Sea off north-eastern Queensland.
