Gymnelinae is a subfamily of marine ray-finned fish belonging to the family Zoarcidae, the eelpouts. Most species are found in the North Pacific Ocean but one genus is cosmopolitan, and another is endemic to the Southern Ocean.
Gymenlinae was first proposed as a taxonomic grouping in 1861 by Theodore Gill. [1] The subfamily is classified within the eelpout family, Zoarcidae part of the suborder Zoarcoidei within the order Scorpaeniformes. [2] The name of the subfamily derives from its type genus, Gymnelus, which means "naked eel" and refers to the scaleless body of its type species Gymnelus viridis. [3]
Gymnelinae contains the following genera: [4]
Gymnelinae eelpouts have an elongate body and tail. Their branchiostegal membranes have a wide joint with the isthmus, the gill slit typically reaches to around the centre of the base of the pectoral fin, although it may just be a small pore placed high above the pectoral fin. There is normally a pore between the eyes. The caudal fin has between 5 and 12 rays. There are between 4 and 8 suborbital bonmes which form a semicircular ridge around the eye. there are usually no spines in the fins. [5] Most of the species are between 10 and 20 cm (3.9 and 7.9 in) in length but the largest is Gymnelus viridis which has a maximum published total length of 56 cm (22 in). [6]
Gymnelinae eelpouts are mostly found in the North Pacific with one genus, Melanostigma being found around the world, and another, Seleniolycus, being restricted to the Southern Ocean. [5]
The eelpouts are the ray-finned fish family Zoarcidae. As the common name suggests, they are somewhat eel-like in appearance. All of the 300 species are marine and mostly bottom-dwelling, some at great depths. Eelpouts are predominantly found in the Northern Hemisphere. The Arctic, north Pacific and north Atlantic oceans have the highest concentration of species; however, species are found around the globe.
Zoarces is a genus of marine ray-finned fishes belonging to the family Zoarcidae, the eelpouts. It is the only genus in the subfamily Zoarcinae. These eelpouts are found in the northern Atlantic and northern Pacific Oceans.
Aiakas is a genus of marine ray-finned fishes belonging to the family Zoarcidae the eelpouts. These fishes are found in the southwestern Atlantic Ocean.
Bothrocara is a genus of marine ray-finned fishes belonging to the family Zoarcidae, the eelpouts. They are found in the Pacific Ocean with one species reaching the southwestern Atlantic Ocean.
Lycodes is a genus of zoarcid fish in the subfamily Lycodinae. It is the most species-rich genus in its taxonomic family as well as in the Arctic Ocean and adjacent waters. They occupy both shallow waters and deeper waters down to 3000 meters. A few species can occur in brackish waters.
Lycodichthys is a genus of marine ray-finned fish belonging to the family Zoarcidae, the eelpouts. They are found in the Southern Ocean.
Lycenchelys is a genus of marine ray-finned fishes belonging to the family Zoarcidae, the eelpouts. The genus has almost cosmopolitan distribution.
Andriashevia is a monospecific genus of marine ray-finned fish belonging to the subfamiy Gymnelinae of the family Zoarcidae, the eelpouts, its only species is Andriasheevia aptera. It is found in the northwestern Pacific Ocean, where it occurs off the Pacific coast of Japan. It appears to be a demersal fish which is associated with large red gorgonian corals, e.g. Paragorgia. Examinations of the stomach contents of collected specimens has shown that its diet is mainly crustaceans but it likely also feeds on encrusting invertebrates which it searches for among coral branches and the hard substrates they live in. This species attains a maximum published standard length of 19.3 cm (7.6 in). Unlike other species in the subfamily Gymnelinae, this taxon has no pectoral fins. The genus name honours the Soviet ichthyologist Anatoly Petrovich Andriashev for his work on fishes of the Russian Far East and especially eelpouts. The specific name, aptera means "without wings" and refers to the absence of pectoral fins.
Davidijordania is a genus of marine ray-finned fishes belonging to the family Zoarcidae, the eelpouts. The fishes in this genus are found in the northwestern Pacific Ocean.
