Taxonomy

Ocynectes was first proposed as a monospecific genus in 1904 by the American ichthyologists David Starr Jordan and Edwin Chapin Starks with Ocynectes maschalis, which they described from Wakanoura in Wakayama Prefecture in Japan, designated as its type species. [1] [2] The 5th edition of Fishes of the World classifies this genus within the subfamily Cottinae of the family Cottidae, [3] however, other authors classify the genus within the subfamily Psychrolutinae of the family Psychrolutidae. [1]

Etymology

Ocynectes is a combination of ocy, which means "swift", and nectes, meaning "swimmer", an allusion to the large pectoral fins of O. maschalis. [4]

Species

Ocynectes currently contains two recognized species: [5]

Characteristics

Ocynectes was described by Jordan and Starks as being similar to Bero but they highlighted a difference in the lateral line which is not protected by concealed plates, has a tentacle at each pore and is not undulating towards the head. They also note the very large head which was greater than the length of the head or around half the length of the body. [6] Both species are small fishes, O. maschalis attains a maximum published standard length of 10 cm (3.9 in) while O. modestus it is 7 cm (2.8 in). [5]

Distribution and habitat

Ocynectes sculpins are found in the northwestern Pacific Ocean around Japan and Sakhalin with O. maschalis being reported from South Korea. [7] Both species are found in tidal pools. [7] [8]

The Andriyashev largeheaded sculpin is a species of marine ray-finned fish belonging to the family Cottidae, the typical sculpins. This species is found in the northwestern Pacific Ocean. This monospecific genus, and therefore this species, are known from a single specimen, the holotype. This was collected from off Simushir Island in the Kuril Islands at a depth of 100 metres (330 ft). That specimen had a total length of 23.6 cm (9.3 in) long. FishBase classifies this taxon within the Cottidae but other authorities classify it within the subfamily Psychrolutinae of the family Psychrolutidae. The genus name Andriashevicottus includes a patronym, the person honoured was not identified by the describer Fedorov, however, it is almost certainly the Soviet ichthyologist Anatoly Petrovich Andriashev, the patronym is suffixed with Cottus, the type genus of the family Cottidae. The specific name megacephalus means "big head".

The Sakhalin sculpin was first formally described in 1904 by the Russian zoologist Peter Yulievich Schmidt with its type locality given as the Lyutoga River on Sakhalin. This species is sometimes placed in the subgenus Cephalocottus. The specific name is a misspelling of Ambystoma, the axolotl combined with opsis, meanning "having the look of", and Schmidt described it as having a head that is “strongly dorsoventrally depressed, wide, nearly flat dorsally, abruptly sloping laterally, similar to the head of an axolotl” (translation).
