The Cyclopteridae are a family of marine fishes, commonly known as lumpsuckers or lumpfish, in the order Scorpaeniformes. They are found in the cold waters of the Arctic, North Atlantic, and North Pacific oceans. The greatest number of species are found in the North Pacific. The family name Cyclopteridae derives from the Greek words κύκλος (kyklos), meaning "circle", and πτέρυξ (pteryx), meaning "wing" or "fin", in reference to the circle-shaped pectoral fins of most of the fish in this family.
The Trichodontidae, or sandfishes, are a small family of ray-finned fishes from the order Scorpaeniformes. The species in this family are found in the North Pacific Ocean.
Careproctus is a genus of snailfishes found in benthic and benthopelagic habitats in the Atlantic, Pacific, Arctic and Southern Oceans. Whether they truly are absent from the Indian Ocean is unknown and might be an artifact of limited sampling. They range from shallow coastal seas in the far north of their range to the abyssal zone, at depths of 6 to 5,459 m (20–17,910 ft). In the Northern Hemisphere they mostly live shallower than Paraliparis, but this pattern is reversed in the Southern Hemisphere. Although almost entirely restricted to very cold waters, a single species, C. hyaleius, lives at hydrothermal vents.
Anatoly Petrovich Andriyashev was a Soviet and Russian ichthyologist, marine biologist, and zoogeographist, notable for his studies of marine fauna of the Arctic and the Northern Pacific.
Lethotremus is a monospecific genus of marine ray-finned fish belonging to the family Cyclopteridae, the lumpfishes or lumpsuckers. This genus is found in the northern Pacific Ocean. Following a 2017 taxonomic review by Lee et al., the species Lethotremus awae was reclassified as a species of Eumicrotremus, leaving the genus monotypic with Lethotremus muticus as its only species. Also known as the docked snailfish, is a species of lumpfish native to the Northeast Pacific. It is known from the Bering Sea and the Aleutian Islands, where its range extends to Unimak Pass, and it occurs at a depth range of 58 to 330 m. It is a benthic species that reaches 11.5 cm in total length. It can be found on substrates of mud, rock, or gravel, and it is currently the only known species of Lethotremus, following a reclassification of the second described species in the genus as Eumicrotremus awae.
Cottoidei is a suborder of ray-finned fishes which, according to the 5th edition of Fishes of the World, is placed within the order Scorpaeniformes, alongside the scorpionfishes, flatheads, eelpouts, sticklebacks and related fishes.
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.
Eumicrotremus barbatus, the papillose lumpsucker, is a species of marine ray-finned fish belonging to the family Cyclopteridae, the lumpfishes or lumpsuckers, found in the north Pacific Ocean. This species is characterized by the following unique apomorphies: teeth in the outer row at symphysis of premaxillae fuse with premaxillae, teeth at symphysis of dentary fuse among themselves and with dentary, forming the regular cutting edge; there are numerous barbs on the head and body; the bony plaques located in centers of connective tissue tubercles leaving the edges free. This species was originally classified in the monospecific genus Georgimarinus, but it is now regarded as a species within Eumicrotremus.
The Pacific spiny lumpsucker is a species of bony fish in the family Cyclopteridae.
Eumicrotremus andriashevi, also known as the pimpled lumpsucker, is a species of lumpfish native to the Arctic and North Pacific. In addition to the Arctic Ocean, it may be found in the Chukchi and Bering Seas, where it occurs at a depth range of 20 to 83 m. It is a small bottom-dwelling fish that reaches 4.8 cm in standard length.
Eumicrotremus spinosus, commonly known as the Atlantic spiny lumpsucker, is a species of lumpfish native to the Arctic and North Atlantic.
Eumicrotremus jindoensis is a species of lumpfish native to the Northwest Pacific, where it may be found off the coast of the Korean Peninsula and in the Yellow Sea. It occurs at a depth range of 20 to 30 metres, and it reaches 2.5 centimetres (1 in) SL. This species was described in 2017 as part of a review of "dwarf" species of Eumicrotremus, which reclassified the species then known as Lethotremus awae as a member of Eumicrotremus in addition to describing another similarly small new species, known as Eumicrotremus uenoi.
Eumicrotremus pacificus, sometimes known as the spotted lumpsucker or the balloon lumpfish, is a species of lumpfish native to the Northwest Pacific. It can be found in the Sea of Okhotsk, the Sea of Japan, the East China Sea, and the Pacific Ocean off Hokkaido and the Kuril Islands. It may be confused with the closely related Eumicrotremus orbis, which overlaps with E. pacificus in range, although E. pacificus is larger, reaching 20 cm (7.9 inches) TL. This fish is generally yellow to orange in color with small dark spots and its tubercles are usually smaller and less pronounced than E. orbis, giving it a less spiny appearance.
Eumicrotremus schmidti is a species of lumpfish native to the Northwest Pacific. It is a demersal fish known only from the northern Sea of Okhotsk, where it is found at a depth range of 20 to 143 m. Specimens of E. schmidti were once attributed to the related species E. andriashevi, which does not inhabit the Sea of Okhotsk. This species was first formally described in 1955 by the Soviet ichthyologists Georgii Ustinovich Lindberg and Marina Iosifovna Legeza with its type locality given as Penzhinskaya Bay in the Sea of Okhotsk in Russia. The identity of the person honoured in the specific name was not given by Lindberg and Legeza but it is likely to be Petr Yulievich Schmidt, a Russian ichthyologist.
Proeumicrotrmus is a monospecific genus of marine ray-finned fish belonging to the family Cyclopteridae, the lumpfishes or lumpsuckers. The only species in the genus is Proeumicrotremus soldatovi, Soldatov's lumpsucker. This species is found in the Northwest Pacific. It is known from the Sea of Okhotsk, where it can be found at depths of 10 to 350 m. It reaches 26 cm (10 in) in total length, making it larger than average for a lumpfish. It was previously considered a species of Eumicrotremus until a morphology-based revision in 2020 concluded that it represents the only known species of a distinct genus.
Eumicrotremus tartaricus is a species of lumpfish native to the Northwest Pacific. It is known from the Sea of Japan, the Sea of Okhotsk, Peter the Great Bay, and the Pacific coast of the Kuril Islands, where it may be found at a depth range of 20 to 30 m. It has sometimes been considered a subspecies of the Pacific spiny lumpsucker, but it is generally agreed upon that E. tartaricus represents its own distinct species.
Eumicrotremus tokranovi is a species of lumpfish native to the Northwest Pacific, and one of two species some authorities place in the genus Microancathus. It is known from the Kuril Islands. It is distinguished from the closely related E. fedorovi by a taller body and flatter and less developed bone plaques. FishBase does not recognize the genus Microancathus,. This species was described by the Russian ichthyologist Olga Stepanovna Voskoboinikova in 2015 in the proposed new genus, Microancathus and the reclassification of M. fedorovi in that genus. Catalog of Fishes does not recognize the new genus and classifies this species in Eumicrotremus. The specific name honors the ichthyologist Alexei Mikhailovich Tokranovof the Kamchatka Branch of the Pacific Institute of Geography and the Far East Branch of the Russian Academy of Sciences.
Cyclopteroidea is a superfamily of ray-finned fishes within the order Scorpaeniformes. The superfamily comprises 2 families, the Cyclopteridae, the lumpsuckers, of the cool northern seas and the widespread Liparidae, the snailfishes. A common feature shared by these families is that they typically have the pelvic fins modified to form a disc shaped sucker.
Eumicrotremus fedorovi is a species of marine ray-finned fish belonging to the family Cyclopteridae, the lumpfishes or lumpsuckers. This species is found in the northwestern Pacific Ocean around the Kuril Islands. It is a demersal fish that occurs at a depth range of 115 to 370 m. This species was first formally described in 1991 by Sergey Anatolyevich Mandritsa with its type locality given as the Rikord Strait. The specific name honours the Russian zoologist Vladimir Vladimirovich Fedorov who studied the holotype and suggested that it represented a new species.
Dolichopteryx andriashevi is a species of fish endemic to in the Philippine Sea.
