The snailfishes or sea snails, are a family of marine ray-finned fishes. These fishes make up the Liparidae, a family classified within the order Scorpaeniformes.
The Ganges shark is a critically endangered species of requiem shark found in the Ganges River and the Brahmaputra River of India and Bangladesh. It is often confused with the more common bull shark, which also inhabits the Ganges River and is sometimes incorrectly referred to as the Ganges shark. The genus is currently considered to contain three recent species; genetic evidence has shown that both the Borneo river shark and Irrawaddy river shark should be regarded as synonyms of the Ganges shark, expanding the range of the species to Pakistan, Myanmar, Borneo, and Java. The species remains poorly known and very rare.
The sea toads and coffinfishes are a family, the Chaunacidae, of deep-sea ray-finned fishes belonging to the monotypic suborder Chaunacoidei within the order Lophiiformes, the anglerfishes. These are bottom-dwelling fishes found on the continental slopes of the Atlantic, Indian, and Pacific Oceans, at depths to at least 2,460 m (8,070 ft). There have also been findings of deep-sea anglerfishes off the coasts of Australia and New Caledonia. Other findings suggest some genera of Chaunacidae are found near volcanic slopes encrusted with manganese. Of the two genera in the family, Chaunacops are typically found at deeper depths than Chaunax, but with considerable overlap between the two genera.
The quagga catshark is a species of shark belonging to the family Pentanchidae, the deepwater catsharks. A small, slim-bodied shark reaching 37 cm (15 in) in length, it has a distinctive color pattern of narrow, dark brown vertical bars, which resemble those of the quagga. Its head is short and flattened, with a pointed snout tip that is not upturned.
Cetopsis is a genus of catfishes of the family Cetopsidae.
Notoliparis kermadecensis is a species of snailfish (Liparidae) that lives in the deep sea. Endemic to the Kermadec Trench in the Southwest Pacific, it is hadobenthic with a depth range between 6,474 and 7,561 m (21,240–24,806 ft), and can reach a standard length of up to 25.8 cm (10.2 in).
Paraliparis skeliphrus is a species of snailfish. It was described in 2005 from a single poorly preserved specimen of 71 mm standard length collected in 1966 off the Chilean coast near Antofagasta.
Paraliparis carlbondi is a species of snailfish. It was described in 2005 from two specimens collected in 1966 off the coast of Peru.
Paraliparis membranaceus is a species of snailfish only known from a single specimen of 57 mm standard length collected in Sarmiento Channel in the fjordlands of southern Chile.
Notoliparis is a genus of marine ray-finned fish belonging to the family Liparidae, the snailfishes. These fishes are found in deep Oceanic trenches in the South Atlantic South Pacific and Southern Oceans.
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.
Psednos carolinae is a species of snailfish only known from a single male specimen collected in mid-Indian Ocean in 1964.
Liparis fabricii, commonly known as the gelatinous seasnail or gelatinous snailfish, is a benthopelagic species of snailfish from the Arctic Ocean. It has a tadpole-like body with a maximum length of about 20 cm (7.9 in). It is brown to black in coloration with a distinctive dark peritoneum. It preys on small crustaceans and marine worms. It is not commercially important, though it is a valuable food source for predatory fish and seabirds in the Arctic region.
Allocareproctus is a genus of marine ray-finned fishes belonging to the family Liparidae, the snailfishes. These fish are found in the northern Pacific Ocean.
The hardhead snailfish is a species of marine ray-finned fish belonging to the family Liparidae, the snailfishes. This species is found in the northern Pacific Ocean where a single specimen was collected in June 2000 from near the Aleutian Islands at a depth of 285 m (935 ft). The length of the fish was 3.3 cm (1.3 in) SL. This species is the only member of the monospecific genus Lopholiparis. The specific name honors the collector of the holotype, William C. Flerx of the National Marine Fisheries Service.
Hiodon woodruffi is an extinct species of bony fish in the mooneye family, Hiodontidae. The species is known from fossils found in the early Eocene deposits of northern Washington state in the United States and late Eocene deposits in northwestern Montana. The species was first described as Eohiodon woodruffi. H. woodruffi is one of two Eocene Okanagan Highlands mooneye species, and one of five fish identified in the Klondike Mountain Formation.
Liparis gibbus, the polka-dot snailfish, variegated snailfish or dusky snailfish, is a species of marine ray-finned fish belonging to the family Liparidae, the snailfishes. This fish is found in Arctic waters. Juveniles of the species have been found to be biofluorescent.
Pseudoliparis belyaevi is a species of snailfish found in hadal zone of the Northwest Pacific Ocean, particularly the Japan Trench.
Careproctus spiraki, or pimpled snailfish, is a small, marine, bottom-dwelling snailfish. The type specimen was collected in a bottom trawl 457 meters deep in Seguam Pass in the Aleutian Islands. The species was first described to science by J. W. Orr in 2021.
Careproctus maslenikovae, or blushing snailfish, is a small, marine, bottom-dwelling snailfish. The type specimen was collected in a bottom trawl 234 meters deep west of the Islands of Four Mountains in the Aleutian Islands. The species was first described to science by J. W. Orr in 2021.
