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.
Allocareproctus was first proposed as a monospecific genus in 1993 by the Russian ichthyologists Dmitry Leonidovich Pitruk and Vladimir Vladimirovich Fedorov with Careproctus jordani as its only species. C. jordani had been described in 1930 by Charles Victor Burke with its type locality in Sagami Bay in Japan. [2] In 2006 James Wilder Orr and Morgan Scott Busby reviewed the genus, described 4 new species from the Aleutian Islands and confirmed the genus as a valid genus. [3]
Allocareproctus is made up of Careproctus, the original genus of A. jordani, prefixed with allo, which means "other", i.e. close to Careproctus. [4]
Allocareproctus has 5 species currently classified within it: [5]
Allocareproctus is characterized by the first 4 to 8 rays of the dorsal fin having their tips free of the fin membrane and they have papillae associated with of the sensory system on the head. In the skull the symplectic bone extends to the central faces of the quadrate bone and the metapterygoid. [3] The largest species is A. jordani which has a maximum published total length of 34 cm (13 in). [5]
Allocareproctus snailfishes are only found in the northern Pacific Ocean from Japan to the Aleutian Islands. [3] They are bathydemersal fishes found in deep water down to 631 m (2,070 ft). [5]
The snailfishes or sea snails are a family of marine ray-finned fishes. These fishes make up the Liparidae, which is classified within the order Scorpaeniformes.
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.
Aetheliparis rossi is a species of snailfish only known from the mesopelagic zone in the North Atlantic off Cape Hatteras, North Carolina. This species is found at depths of from 500 to 674 metres.
Liparis liparis, the common seasnail, striped seasnail or seasnail, is a small species of marine ray-finned fish belonging to the family Liparidae, the snailfishes, in the order Scorpaeniformes, the scorpionfishes and flatheads. It is found in the northeastern Atlantic Ocean where it lives on the seabed.
Ereunias is a monotypic genus of marine ray-finned fish belonging to the family Rhamphocottidae, the grunt sculpins. Its only species is Ereunias grallator which is a bathydemersal species found at depths of around 500 m (1,600 ft) in the northwestern Pacific Ocean off Japan. This species attains a maximum published total length of 30 cm (12 in). This species was first formally described in 1901 by the American ichthyologists David Starr Jordan and John Otterbein Snyder from Misaki, Sagami in Japan. Jordan and Snyder proposed the new genus Ereunias for the new species. The genus name is derived from ereunao, meaning "to explore" which may refer how it uses elongated pectoral-fin rays as feelers or “feet” to explore the substrate; suffixed with ias which is used in some Greek names for fishes. The specific name grallator is "stiltwalker" in Latin and is an allusion to the elongated pectoral fin rays. Along with the genus Marukawichthys this taxon was classified in the family Ereunidae but this was synonymised with the Rhamphocottidae in 2014.
Acantholiparis is a genus of marine ray-finned fishes belongong to the family Liparidae, the snailfishes. These fishes are found in the northern Pacific Ocean.
Crystallichthys is a genus of marine ray-finned fishes belonging to the family Liparidae, the snailfishes. These fishes are found in the northern Pacific Ocean.
Elassodiscus is a genus of marine ray-finned fishes belonging to the family Liparidae, the snailfishes. These fishes are found in the 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.
Osteodiscus is a genus of snailfishes native to the Pacific Ocean.
Adelosebastes is a monotypic genus of marine ray-finned fish belonging to the subfamily Sebastinae, the rockfishes, part of the family Scorpaenidae. The only species in this genus is Adelosebastes latens, the Aleutian scorpionfish. It is found in the northern 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.
Liparis atlanticus, the Atlantic snailfish or Atlantic seasnail, is a species of marine ray-finned fish belonging to the family Liparidae, the snailfishes. This species is found in the western Atlantic Ocean off the eastern coast of North America.
The yellow Irish lord is a species of marine ray-finned fish belonging to the family Agonidae It is found in the northern Pacific Ocean.
Careproctus ovigerus, commonly known as the abyssal snailfish, is a species of snailfish found in the northeastern Pacific Ocean. It is found at depths of 1,920–2,910 m (6,300–9,550 ft) off northern British Columbia and off Washington state.
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.
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.
James Wilder Orr is an American fisheries biologist, ichthyologist, and systematist best known for his studies of skates, rockfishes, snailfishes, and flatfishes. He has described 32 new species and two new genera of fishes, and is the author or co-author of more than 130 scientific and popular articles, including three books. His work has focused primarily on the phylogenetic relationships, zoogeography, reproductive biology, and behavior of marine teleosts, particularly deep-water benthic taxa. He has spent most of his career at the Alaska Fisheries Science Center, National Marine Fisheries Service (NMFS), in Seattle, as a Research Fisheries Biologist. At the same time, he has served as an Affiliate Professor at the School of Aquatic and Fishery Sciences, and Affiliate Curator of Fishes at the Burke Museum of Natural History and Culture, University of Washington, Seattle. For his lifetime of service, Orr was presented with a National Oceanic and Atmospheric Administration (NOAA) Distinguished Career Award in 2022.
