Eulophiidae, the spinous eelpouts, is a small family of marine ray-finned fishes classified within the suborder Zoarcoidei of the order Scorpaeniformes. They are found in the northwestern Pacific Ocean.
Eulophiidae was first proposed as a family in 2013 by the Korean biologists Hyuck Joon Kwun and Jin-Koo Kim for the genus Eulophias, which had previously been classified as belonging to the family Stichaeidae. Kwun and Kim argued that the molecular phylogenetics showed that Eulophias was only distantly related to the species classified within the Stichaeidae. [1] This was suuported by further molecular phylogenetic analyses published in 2014. [2] and the validity of the family has been accepted by the 5th edition of Fishes of the World , [3] by FishBase [4] and by the Catalog of Fishes . [5] The type species of the family, Eulophias tanneri , was described from Japan by Hugh McCormick Smith in 1902, Smith thought that his new species was a blenny but was different enough from other blennies that he proposed a new subfamily, Eulophiasinae, as a monotypic subfamily of the Blennidae, [6] Jordan and Snyder changed the name to Eulophinae in 1902. [7] The genera Eulophias and Azygopterus were subsequently placed in the subfamily Neozarchinae in the tribe Eulophini prior to Kwun and Kim's analysis. [8]
The 5th edition of Fishes of the World classifies this family within the suborder Zoarcoidei, within the order Scorpaeniformes. [3] Other authorities classify this family in the infraorder Zoarcales within the suborder Cottoidei of the Perciformes because removing the Scorpaeniformes from the Perciformes renders that taxon non monophyletic. [9]
Eulophiidae contains the following 3 genera, and only 4 or 5 species are classified as belonging to the family: [4] [5]
The family name is based on the name Smith gave to Eulophias tanneri in 1902 and is a combination of eu, meaning “well”, and lophias, which means “bristley backed”, a reference to the long, spiny dorsal fin of that species. [10]
Eulophiidae fishes are characterised by having an almost completely spiny dorsal fin, [4] the pectoral fins may be absent or have at most 7 rays, there are no teeth on the vomerine or on the palatine teeth, they have 6 branchiostegal rays, there is no pyloric caeca, they have between 26 and 45 vertebrae in front of the tail and the parietals do not meet at the midline of the skull. [8]
Eulophidae fishes are found in the North Western Pacific Ocean off Japan, Korea and the Russian Far East. [8]
The Scorpaeniformes are a diverse order of ray-finned fish, including the lionfishes and sculpins, but have also been called the Scleroparei. It is one of the five largest orders of bony fishes by number of species, with over 1,320.
Ronquils is a small family marine ray-finned fish, the Bathymasteridae. These fishes are found only in Arctic and North Pacific waters. This family contains just seven species in three genera. The larger species are important to commercial fisheries as food fish. Ronquils are most closely related to the eelpouts and prowfish in the suborder Zoarcoidei of the order Scorpaeniformes.
Anarhichadidae, the wolffishes, sea wolves or wolf eels, is a family of marine ray finned fishes belonging to the order Scorpaeniformes. These are predatory, eel shaped fishes which are native to the cold waters of the Arctic, North Pacific and North Atlantic Oceans.
Pholidae is a family of marine ray-finned fishes, known as gunnels, in the scorpaeniform suborder Zoarcoidei. These are fishes of the littoral zone and are mainly found in North Pacific Ocean, with two species found in the North Atlantic Ocean and Arctic Ocean.
Stichaeidae, the pricklebacks or shannies, are a family of marine ray-finned fishes in the suborder Zoarcoidei of the order Scorpaeniformes. Most species are found in the North Pacific Ocean with a few in the North Atlantic Ocean.
The quillfish,, is a species of marine ray-finned fish, it is the only species in the genus Ptilichthys and family Ptilichthyidae. This fish occurs in the northern North Pacific Ocean.
The stripedfin ronquil, also known as the bluebanded ronquil, is a species of marine ray-finned fish belonging to the family Bathymasteridae, the ronquils. This fish is found in the eastern Pacific Ocean.
Zoarcoidei is a suborder of marine ray-finned fishes belonging to the order Scorpaeniformes. The suborder includes the wolffishes, gunnels and eelpouts. The suborder includes about 400 species. These fishes predominantly found in the boreal seas of the northern hemisphere but they have colonised the southern hemisphere.
Anarhichas is a genus of marine ray-finned fishes belonging to the family Anarhichadidae, the wolffishes or sea wolves. These fishes are found in the northern North Atlantic and North Pacific oceans.
Cryptacanthodes is a genus of marine ray-finned fishes belonging to the monogeneric family Cryptacanthodidae, commonly referred to as wrymouths. Three of the four species are found in the Pacific Ocean with one species native to the western Atlantic Ocean where they are benthic fishes, tunneling through soft substrates. It is currently the only known genus in its family.
Bathymaster is a genus of marine ray-finned fishes belonging to the family Bathymasteridae, the ronquils. These fishes are found in the northern Pacific Ocean.
Rathbunella is a genus of marine ray-finned fishes belonging to the family Bathymasteridae, the ronquils. These fishes are found in the eastern Pacific Ocean.
The northern ronquil is species of marine ray-finned fish belonging to the family Bathymasteridae, the ronquils. This species is found in the eastern Pacific Ocean. This species is the only known member of its genus.
The stippled gunnel is a species of marine ray-finned fish belonging to the family Pholidae, the gunnels. It is the only species in the monospecific genus Rhodymenichthys. It is found in the northern North Pacific Ocean.
Stichaeinae is a subfamily of marine ray-finned fishes, classified within the family Stichaeidae, the pricklebacks or shannies. These fishes are found in the North Pacific, Arctic and North Atlantic Oceans.
The crisscross prickleback is a species of marine ray-finned fish belonging to the family Stichaeidae, the pricklebacks and shannies. It is the only species in the monotypic genus Plagiogrammus. This fish is found in the eastern Pacific Ocean off California.
