Taxonomy

Artedius was first proposed as a genus in 1854 by the French zoologist Charles Frédéric Girard with Scorpaenichthys lateralis, described by Girard from California in 1854, designated as its type species by Jordan and Evermann in 1896. [1] The 5th edition of Fishes of the World classifies this genus in the subfamily Cottinae of the family Cottidae [3] but other authorities classify it in the subfamily Oligocottinae of the family Psychrolutidae. [1]

Etymology

Artedius suffixes ius, meaning “belonging to” Artedi; Girard did not explain who this was honouring but it is almost certain that it is Peter Artedi, the “father of ichthyology”. [4]

Species

There are currently five recognized species in this genus: [5]

Characteristics

Artedius sculpins are similar to many other cottid genera. They share the following identifying characteristics. They do not possess any postcleithra in the pelvic girdle, they have two or three parallel scale rows in the axilla of the pectoral fins with no cirrhi above these. There is a triangular extension of the pterotic bone which extends onto the edge of the cranium, The chin are dark in colour broken by paler circular blotches and the dark flanks are broken by colourless circular blotches too. [6] The largest species is the bonehead sculpin ( A. notospilotus ) which has a maximum published total length of 25 cm (9.8 in) while the smallest is the scalyhead sculpin ( Artedius harringtoni ) which has a maximum published total length of 10 cm (3.9 in). [5]

Distribution

Artedius sculpins are found in the eastern North Pacific Ocean from the Komandorski Islands, Russia, south along the Pacific coast of North America to northern Baja California in Mexico. [5]

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".

Argyrocottus is a monospecific genus of marine ray-finned fish belonging to the family Cottidae, the typical sculpins. Its only species is Argyrocottus zanderi which is found in the northwestern Pacific Ocean from Japan to the Kuril Islands and in the Sea of Japan. It is found at depths of from 0 to 85 metres. This species grows to a standard length of 9 centimetres (3.5 in). This taxon was first formally described in 1892 by the Russian zoologist Solomon Herzenstein with its type locality given as Korsakov on Sakhalin in the Sea of Okhotsk. The 5th edition of Fishes of the World classifies the genus Argyrocottus within the subfamily Cottinae of the family Cottidae, however, other authors classify the genus within the subfamily Myoxocephalinae of the family Psychrolutidae. although others place the subfamily Myoxocephalinae within the Cottidae.
