Opah

Opah (also commonly known as moonfish, sunfish, kingfish, redfin ocean pan, and Jerusalem haddock) are large, colorful, deep-bodied pelagic Lampriform fish comprising the small family Lampridae (also spelled Lamprididae). There are only two living species in a single genus: Lampris (from the Greek lamprid-, "brilliant" or "clear"). One species is found in tropical to temperate waters of most oceans, while the other is limited to a circumglobal distribution in the Southern Ocean, with the 34th parallel as its northern limit. Two additional species, one in the genus Lampris and the other in the monotypic Megalampris, are only known from fossil remains. The extinct family, Turkmenidae, from the Paleogene of Central Asia, is closely related, though much smaller.
