Gymnelus is a genus of small fish in the family Zoarcidae found in the Arctic Ocean, and adjacent parts of the North Pacific and North Atlantic. They are highly variable in color, which has resulted in the description of several taxa now considered invalid.
Species There are currently eleven recognized species in this genus:
Gymnelus andersoni Chernova, 1998 Gymnelus diporus Chernova, 2000 Gymnelus gracilis Chernova, 2000 Gymnelus hemifasciatus Andriashev, 1937 (Halfbarred pout) Gymnelus obscurus Chernova, 2000 Gymnelus pauciporus Anderson, 1982 Gymnelus popovi (Taranetz & Andriashev, 1935) (Aleutian pout) – often in monotypic genus Commandorella Gymnelus retrodorsalis Le Danois, 1913 (Aurora unernak) Gymnelus soldatovi Chernova, 2000 Gymnelus taeniatus Chernova, 1999 Gymnelus viridis J. C. Fabricius, 1780 (Fish doctor)
