Cod Icefish
: ''In some scientific literature, the term "cod icefish" is used to identify members of this family. This should not be confused with the term "icefish," which refers to the "white-blooded" fishes of the family Channichthyidae. See Icefish (other).'' Nototheniidae, the notothens or cod icefishes, is a family of ray-finned fishes, part of the suborder Notothenioidei which is traditionally placed within the order Perciformes. They are largely found in the Southern Ocean. Taxonomy Nototheniidae was described as a family in 1861 by the German-born British ichthyologist Albert Günther with the type genus being ''Notothenia'' which had been described in 1844 by Sir John Richardson with the species ''Notothenia coriiceps'' which Richardson had also described in 1844 subsequently being designated as the type in 1862 by Theodore Nicholas Gill. The name ''Notothenia'' means “coming from the south”, a reference to the Antarctic distribution of the genus. They are tradit ...

Channichthyidae
The crocodile icefish or white-blooded fish comprise a family (Channichthyidae) of notothenioid fish found in the Southern Ocean around Antarctica. They are the only known vertebrates to lack hemoglobin in their blood as adults. Icefish populations are known to reside in the Atlantic and Indian sectors of the Southern Ocean, as well as the continental shelf waters surrounding Antarctica. Water temperatures in these regions remain relatively stable, generally ranging from . One icefish, ''Champsocephalus esox,'' is distributed north of the Antarctic Polar Frontal Zone. At least 16 species of crocodile icefish are currently recognized, although eight additional species have been proposed for the icefish genus ''Channichthys.'' In February 2021, scientists discovered and documented a breeding colony of ''Neopagetopsis ionah'' icefish estimated to have 60 million active nests across an area of approximately 92 square miles at the bottom of the Weddell Sea in Antarctica. The majority ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almost al ...

Lepidonotothen
The grey rockcod (''Lepidonotothen squamifrons''), also known as the grey notothen, stripe-eyes notothen or stripe-eyed rockcod, is a species of marine ray-finned fish belonging to the family Nototheniidae, the notothens or cod icefishes. It is native to the Southern Ocean. The grey rockcod feeds mainly on macrozooplankton and is of minor importance to commercial fisheries. It is the only species in the genus ''Lepidonotothen''. Taxonomy The grey rockcod was first formally described in 1880 as ''Notothenia squamifrons'' by the German-born British ichthyologist Albert Günther with the type locality given as Kerguelen Island.

Pleuragramma
The Antarctic silverfish (''Pleuragramma antarctica''), or Antarctic herring, is a species of marine ray-finned fish belonging to the Family (biology), family Nototheniidae, the notothens or cod icefishes. It is native to the Southern Ocean and the only truly pelagic fish in the waters near Antarctica. It is a keystone species in the ecosystem of the Southern Ocean.Bottaro M., Oliveri D., Ghigliotti L., Pisano E., Ferrando S. & Vacchi M. (2009).

Gvozdarus
''Gvozdarus'' is a genus of marine ray-finned fishes belonging to the family Nototheniidae, the notothens or cod icefishes. It is native to the Southern Ocean. Taxonomy ''Gvozdarus'' was first formally described as a genus in 1989 by the Soviet ichthyologist Arkady Vladimirovich Balushkin with the type species by monotypy being ''Gvozdarus svetovidovi'', a second species has subsequently been described. Some authorities place this taxon in the subfamily Pleuragrammatinae, but the 5th edition of ''Fishes of the World'' does not include subfamilies in the Nototheniidae. The name of the genus is a Latinised version of a local name for the zander (''Sander lucioperca'') in Veliky Novgorod, Russia. Balushkin did not explain why he chose this name but it may refer to the similarity in form of ''G. svetovidovi'', especially the long, pointed teeth, to the zander. Species The recognized species in this genus are: * '' Gvozdarus balushkini'' Voskoboinikova & Kellermann, 1993 * '' Gvoz ...

Dissostichus
''Dissostichus'', the toothfish, is a genus of marine ray-finned fish belonging to the family Nototheniidae, the notothens or cod icefish. These fish are found in the Southern Hemisphere. Toothfish are marketed in the United States as Chilean sea bass (or Chilean seabass) or less frequently as white cod. "Chilean sea bass" is a marketing name coined in 1977 by Lee Lantz, a fish wholesaler who wanted a more attractive name for selling the Patagonian toothfish to Americans. Retrieved on 16 May 2015.G. Bruce Knecht, ''Hooked: Pirates, Poaching, And the Perfect Fish", 2006. . p. 9'' In 1994, the U.S. Food and Drug Administration (FDA) accepted "Chilean sea bass" as an "alternative market name" for Patagonian toothfish. The toothfish was remarkably successful in the United States, Europe and Asia, and earned the nickname "white gold" within the market. Toothfish are vital to the ecological structure of Southern Ocean ecosystems. For this reason, on 4 September a national day is dedic ...

Hugh Hamilton DeWitt
Hugh Hamilton DeWitt (28 December 1933-5 January 1995) was an American ichthyologist, marine biologist and oceanographer. DeWitt was born on 28 December 1933 in San Jose, California, son of Carl Bryce Seligman, a country doctor, and Honor Pettit Seligman, a teacher of mathematics and Latin. His surname at birth was Seligman but at his father's urging he and his brothers changed their name to DeWitt in the 1950s, a name from their mother’s side of the family, as they had encountered mistaken preconceptions while attending High Schools in the eastern United States. His brothers were the theoretical physicist Bryce Seligman DeWitt, Lloyd Lewis DeWitt (1926-1988), who joined the United States Foreign Service and Hiram Pettit DeWitt (b.1936), a teacher. He grew up largely in California, leaving to attend high school at the Putney School in Vermont. He returned to California to enrol at Stanford University, gaining his Bachelor's degree in 1955, masters in 1960 and doctorate in 1966, ...

Aethotaxis
The longfin icedevil (''Aethotaxis mitopteryx''), also known as the threadfin pinhead, is a species of marine ray-finned fish belonging to the family Nototheniidae, the notothens or cod icefishes. It is native to the Southern Ocean where it can be found at depths down to . This species grows to a length of TL. This species is the only known member of its genus and is of no interest to commercial fisheries. Taxonomy The longfin icedevil was first formally described in 1962 by the American ichthyologist Hugh H. DeWitt with the type locality given as off Pram Point on Ross Island in McMurdo Sound, Antarctica at 77°53'S, 166°44'E, the type being picked up dead at the surface. Dewitt placed the new species in the monotypic genus ''Aethotaxis'' in which it is still the only species. The species is sometimes split into 2 subspecies, with ''A.m. pawsoni'' proposed as a subspecies in the Weddell Sea and the Scotia Sea but this requires more evidence.
