Histiophryne

Histiophryne is a genus of frogfishes found in waters ranging from Taiwan to South Australia. There are currently three known species. These fishes are easily distinguished from other anglerfishes as having a reduced (or missing) luring appendage, a highly evolved form of the first dorsal fin spine. The second and third spines are immobile and reduced as well to mere bumps beneath the skin. The rear fins extend past the body of the fish and meet its tail fin.
