|Scopelogadus mizolepis mizolepis, a ridgehead|
The Stephanoberyciformes are an order of marine ray-finned fishes, consisting of about 45 species, the majority (37) of which belong to the ridgehead family (Melamphaidae). The Stephanoberyciformes are mostly uncommon deep-sea species with little, if any, importance to commercial fishery. They share many morphological similarities with the Beryciformes, their sister order.
The families are:
- Melamphaidae – ridgeheads (about 35 species)
- Gibberichthyidae – gibberfishes (2 species)
- Stephanoberycidae – pricklefishes (3 species)
- Hispidoberycidae - Bristlyskin (1 species)
The gibberfishes on the other hand appear to be closer to whalefishes such as Rondeletia, as has been proposed time and again. These two groups have - apparently as only living fishes - the mysterious Tominaga's organ. Rondeletia, meanwhile, is suspected to be very close to the velvet whalefish, Barbourisia rufa.
