Paranotothenia
''Paranotothenia'' is a genus of marine ray-finned fishes belonging to the family Nototheniidae, the notothens or cod icefishes. These fishes are native to the Southern Ocean. Taxonomy ''Paranotothenia'' was first formally described as a genus in 1976 by the Soviet ichthyologist Arkady Vladimirovich Balushkin, it was originally a monotypic genus with ''Gadus magellanicus'', which had been described in 1801 by Johann Reinhold Forster with the type locality given as the Straits of Magellan. as its type species. Some authorities place this genus in the subfamily Nototheniinae, but the 5th edition of '' Fishes of the World'' does not include subfamilies in the Nototheniidae. The genus name is a compound of ''para'' meaning "near" or "similar to" and ''Notothenia'', the type genus of Nototheniidae, from which it differs by being short snouted and having crests above the eye. Species The recognized species in this genus are: * '' Paranotothenia dewitti'' Balushkin, 1990 * '' Para ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paranotothenia Magellanica
''Paranotothenia magellanica''), also known as Magellanic rockcod, Maori cod, blue notothenia or orange throat notothen, 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. " Maori chief" and " black cod", sometimes used for this species, usually refer to fishes from the related genus ''Notothenia''. Being a perciform fish, it is unrelated to the true cods of the order Gadiformes. This species is commercially important as a food fish. Taxonomy ''Paranotothenia magellanica'' was first formally described as ''Gadus magellanicus'' in 1801 by the German naturalist Johann Reinhold Forster with the type locality given as the Straits of Magellan. The Russian ichthyologist Arkady Vladimirovich Balushkin placed it in its own monotypic genus, ''Paranotothenia'', in 1976. A second species '' P. dewitti'' was described by Balushkin in 1990. The specific name refers to the type locality. Des ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paranotothenia Dewitti
''Paranotothenia dewitti'' 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 is found in the area of sea which the Russians refer to as the Somov Sea. This species was first formally described in 1990 by the Russian ichthyologist Arkady Vladimirovich Balushkin with the type locality given as the Somov Sea at 64°04'S, 165°39'E. Balushkin did not identify who he honoured in the specific name but it is almost certainly the American ichthyologist 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 ....

Notothenia Trigramma
''Notothenia trigramma'' is a species of marine ray-finned fish, belonging to the family Nototheniidae, the notothens or cod icefishes. It occurs in the southwestern Atlantic Ocean. Taxonomy ''Notothenia trigramma'' was first formally described in 1913 by the English ichthyologist Charles Tate Regan with the type locality given as the harbour at Port Stanley in the Falkland Islands, the type specimen being collected on the Scottish National Antarctic Expedition. Some authorities classify this species in the genus '' Paranotothenia'', although FishBase has retained it in the genus ''Notothenia'' pending further studies. Other authorities have placed this species in the genus '' Patagonotothen'' and some have regarded it as a synonym of '' Patagonotothen canina''. The specific name ''trigramma'' means “three lined”, a reference to the three lateral lines possessed by this species.

Nototheniidae
: ''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 traditio ...

Caudal Fin
Fins are distinctive anatomical features composed of bony spines or rays protruding from the body of a fish. They are covered with skin and joined together either in a webbed fashion, as seen in most bony fish, or similar to a flipper, as seen in sharks. Apart from the tail or caudal fin, fish fins have no direct connection with the spine and are supported only by muscles. Their principal function is to help the fish swim. Fins located in different places on the fish serve different purposes such as moving forward, turning, keeping an upright position or stopping. Most fish use fins when swimming, flying fish use pectoral fins for gliding, and frogfish use them for crawling. Fins can also be used for other purposes; male sharks and mosquitofish use a modified fin to deliver sperm, thresher sharks use their caudal fin to stun prey, reef stonefish have spines in their dorsal fins that inject venom, anglerfish use the first spine of their dorsal fin like a fishing rod to lu ...

Ctenoid
A fish scale is a small rigid plate that grows out of the skin of a fish. The skin of most jawed fishes is covered with these protective scales, which can also provide effective camouflage through the use of reflection and colouration, as well as possible hydrodynamic advantages. The term ''scale'' derives from the Old French , meaning a shell pod or husk. Scales vary enormously in size, shape, structure, and extent, ranging from strong and rigid armour plates in fishes such as shrimpfishes and boxfishes, to microscopic or absent in fishes such as eels and anglerfishes. The morphology of a scale can be used to identify the species of fish it came from. Scales originated within the jawless ostracoderms, ancestors to all jawed fishes today. Most bony fishes are covered with the cycloid scales of salmon and carp, or the ctenoid scales of perch, or the ganoid scales of sturgeons and gars. Cartilaginous fishes (sharks and rays) are covered with placoid scales. Some species ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fishes Of The World
''Fishes of the World'' by the American ichthyologist Joseph S. Nelson (1937–2011) is a standard reference for fish systematics. Now in its fifth edition (2016), the work is a comprehensive overview of the diversity and classification of the 30,000-plus fish species known to science. The book begins with a general overview of ichthyology, although it is not self-contained. After a short section on Chordata and non-fish taxa, the work lists all known fish families in a systematic fashion. Each family (biology), family gets at least one paragraph, and usually a body outline drawing; large families have subfamilies and tribes described as well. Notable genera and species are mentioned, while the book generally does not deal with the species-level diversity. The complexities of the higher taxa are described succinctly, with many references for difficult points. The book does not involve color illustrations. The fourth edition was the first to incorporate the wide use of DNA analy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Straits Of Magellan
The Strait of Magellan (), also called the Straits of Magellan, is a navigable sea route in southern Chile separating mainland South America to the north and Tierra del Fuego to the south. The strait is considered the most important natural passage between the Atlantic and Pacific oceans. It was discovered and first traversed by the Spanish expedition of Ferdinand Magellan in 1520, after whom it is named. Prior to this, the strait had been navigated by canoe-faring indigenous peoples including the Kawésqar. Magellan's original name for the strait was ''Estrecho de Todos los Santos'' ("Strait of All Saints"). The King of Spain, Emperor Charles V, who sponsored the Magellan-Elcano expedition, changed the name to the Strait of Magellan in honor of Magellan. The route is difficult to navigate due to frequent narrows and unpredictable winds and currents. Maritime piloting is now compulsory. The strait is shorter and more sheltered than the Drake Passage, the often stormy open sea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subfamily
In biological classification, a subfamily (Latin: ', plural ') is an auxiliary (intermediate) taxonomic rank, next below family but more inclusive than genus. Standard nomenclature rules end subfamily botanical names with "-oideae", and zoological names with "-inae". See also * International Code of Nomenclature for algae, fungi, and plants * International Code of Zoological Nomenclature * Rank (botany) * Rank (zoology) In biological classification, taxonomic rank is the relative level of a group of organisms (a taxon) in an ancestral or hereditary hierarchy. A common system consists of species, genus, family, order, class, phylum, kingdom, domain. While ... Sources {{biology-stub ...
