Binomial Nomenclature
In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, name or a scientific name; more informally it is also historically called a Latin name. The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Homo sapiens''. ''Tyrannosaurus rex'' is likely the most widely known binomial. The ''formal'' introduction of this system of naming species is credit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Patagonotothen Longipes
''Patagonotothen'' is a genus of marine ray-finned fishes, belonging to the family Nototheniidae, the notothens or cod icefishes. They are native to the southeast Pacific Ocean, southern Atlantic Ocean and the Southern Ocean. Taxonomy ''Patagonotothen'' was first formally described in 1976 by the Soviet ichthyologist Arkady Vladimirovich Balushkin with ''Notothenia tessellata'', which had been described in 1845 by the Scottish naturalist, Arctic explorer and naval surgeon John Richardson with a type locality of the Falkland Islands, as the 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 ''Patago'', a reference to Patagonia, and ''notothen'', indicating that this genus is part of the family Nototheniidae. Species The 15 recognized species in this genus are: * '' Patagonotothen brevicauda'' (Lönnberg, 1905) (Patagon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Champsocephalus Esox
''Champsocephalus esox'', the pike icefish or northern icefish, is a species of marine ray-finned fish belonging to the family Channichthyidae, the crocodile icefishes. Taxonomy ''Champsocephalus esox'' was first formally described in 1861 as ''Chaenichthys esox'' by the German-born British ichthyologist Albert Günther with the type locality given as Port Famine in Chile. In 1862 the American ichthyologist Theodore Nicholas Gill placed it in the new monotypic genus ''Champsocephalus''. The ''specific name'' ''esox'' means “pike”, Günther did not explain why but it may be because of the resemblance to the Northern pike (''Esox lucius''). Description ''Champsocephalus esox'' has a whitish body, dark brown caudal fins, and dark brown bars (sometimes forming irregular dark blotches connected with yellowish regions) with no scales except on its lateral line. Distribution and habitat ''Champsocephalus esox'' is found at depths of in the oceans off Patagonia, the Falkland ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beagle Channel
Beagle Channel (; Yahgan: ''Onašaga'') is a strait in the Tierra del Fuego Archipelago, on the extreme southern tip of South America between Chile and Argentina. The channel separates the larger main island of Isla Grande de Tierra del Fuego from various smaller islands including the islands of Picton, Lennox and Nueva; Navarino; Hoste; Londonderry; and Stewart. The channel's eastern area forms part of the border between Chile and Argentina and the western area is entirely within Chile. The Beagle Channel, the Straits of Magellan to the north, and the open-ocean Drake Passage to the south are the three navigable passages around South America between the Pacific and Atlantic Oceans. Most commercial shipping uses the open-ocean Drake Passage. The Beagle Channel is about long and wide at its narrowest point. It extends from Nueva Island in the east to Darwin Sound and Cook Bay in the Pacific Ocean in the west. Some from its western end, it divides into two branches, north ...
