Sebastolobus
''Sebastolobus'', the thornyheads, is a genus of marine ray-finned fish belonging to the subfamily Sebastinae, the rockfishes, part of the family Scorpaenidae. These fishes are native to the northern and eastern Pacific Ocean. They are generally found in deep waters. Taxonomy ''Sebastolobus'' was first described as a genus by the American ichthyologist Theodore Gill in 1881 with ''Sebastes macrochir'', a species described, with its type locality given as Japan, by the German-born British ichthyologist and herpetologist Albert Gunther in 1877. It is the type genus of the tribe Sebastolobini, on of two in the Sebastinae, a subfamily of the family Scorpaenidae. The generic name is a compound of ''Sebastes'', the original genus of the type species, and ''lobus'', “lobed”, a reference to the lower rays of the pectoral fins being widened into tongue-shaped lobes.

Sebastolobus Macrochir
''Sebastolobus macrochir'', the broadbanded thornyhead or broadfin thorny head, is a species of marine ray-finned fish belonging to the subfamily Sebastinae, the rockfishes, part of the family Scorpaenidae. It is found in deep waters of the northwestern Pacific Ocean. Taxonomy ''Sebastolobus macrochir'' was first formally described in 1877 as ''Sebastes macrochir'' by the German born British ichthyologist and herpetologist Albert Günther with the type locality given as the Inland Sea of Japan. When the American ichthyologist Theodore Gill described the genus ''Sebastolobus'' Sebastes macrochir was the type species by monotypy, two other species have since been added. The specific name ''acrochir'' is a compound of ''macro'' which means "long" or "large" and ''cheirus'' meaning "hand", an allusion to the broad pectoral fin with its upper 5 or 6 tays elongatedrays. Description ''Sebastolobus macrochir'' has 15-16 spines and 8-10 soft rays in its dorsal fin and 3 spines and 5 sof ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sebastolobini
Sebastini is a tribe of marine ray-finned fishes belonging to the subfamily Sebastinae of the family Scorpaenidae in the order Scorpaeniformes. Many species have the common name thornyhead. Taxonomy Sebastolobini was first formally recognised as a grouping in 1943 by the Japanese ichthyologist Kiyomatsu Matsubara. Authorities who treat the clade referred to as Sebastinae as a family treat the Sebastolobini as a subfamily and call this grouping Sebastolobinae. Genera Sebastini contains three genera with 11 species, most in ''Trachyscorpia''. * '' Adelosebastes'' Eschmeyer, T.

Sebastinae
Sebastinae is a subfamily of marine fish belonging to the family Scorpaenidae in the order Scorpaeniformes. Their common names include rockfishes, rock perches, ocean perches, sea perches, thornyheads, scorpionfishes, sea ruffes and rockcods. Despite the latter name, they are not closely related to the cods in the genus ''Gadus'', nor the rock cod, ''Lotella rhacina''. Taxonomy Sebastinae, or Sebastidae, was first formally recognised as a grouping in 1873 by the German naturalist Johann Jakob Kaup. Some authorities recognise this family as distinct from Scorpaenidae. FishBase, a finfish database generated by a consortium of academic institutions, does, but the United States Federal government's Integrated Taxonomic Information System and the 5th Edition of ''Fishes of the World'' do not, FotW classify it as a subfamily of the Scorpaenidae. Tribes and genera Sebastinae is divided into two tribes and seven genera: * Tribe Sebastini Kaup, 1873 ** ''Helicolenus'' Goode & Bean, 1 ...

Tarleton Hoffman Bean
Tarleton Hoffman Bean (October 8, 1846 – December 28, 1916) was an American ichthyologist. Biography and education Tarleton Hoffman Bean was born to George Bean and Mary Smith Bean in Bainbridge, Pennsylvania, on October 8, 1846. He attended State Normal School at nearby Millersport, Pennsylvania, graduating in 1866. He received an M.D. degree from Columbian University, now George Washington University, Washington, DC, 1876. In 1883, he was awarded an M.S. degree from the Indiana University on the basis of his professional accomplishments, although he did not attend classes there. He married Laurette H. van Hook, daughter of John Welsh VanHook, a local Washington businessman, in 1878 in Washington, DC. They had one daughter, Caroline van Hook Bean (born in Washington on November 16, 1879), a noted artist who later married Bernardus Blommers, Jr. His brother, Barton Appler Bean, also became an ichthyologist and worked under him at the National Museum.

Oviparous
Oviparous animals are animals that lay their eggs, with little or no other embryonic development within the mother. This is the reproductive method of most fish, amphibians, most reptiles, and all pterosaurs, dinosaurs (including birds), and monotremes. In traditional usage, most insects (one being ''Culex pipiens'', or the common house mosquito), molluscs, and arachnids are also described as oviparous. Modes of reproduction The traditional modes of reproduction include oviparity, taken to be the ancestral condition, traditionally where either unfertilised oocytes or fertilised eggs are spawned, and viviparity traditionally including any mechanism where young are born live, or where the development of the young is supported by either parent in or on any part of their body. However, the biologist Thierry Lodé recently divided the traditional category of oviparous reproduction into two modes that he named ovuliparity and (true) oviparity respectively. He distinguished the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Demersal Fish
Demersal fish, also known as groundfish, live and feed on or near the bottom of seas or lakes (the demersal zone).Walrond Carl . "Coastal fish - Fish of the open sea floor"Te Ara - the Encyclopedia of New Zealand. Updated 2 March 2009 They occupy the sea floors and lake beds, which usually consist of mud, sand, gravel or rocks. In coastal waters they are found on or near the continental shelf, and in deep waters they are found on or near the continental slope or along the continental rise. They are not generally found in the deepest waters, such as abyssal depths or on the abyssal plain, but they can be found around seamounts and islands. The word ''demersal'' comes from the Latin ''demergere'', which means ''to sink''. Demersal fish are bottom feeders. They can be contrasted with pelagic fish which live and feed away from the bottom in the open water column. Demersal fish fillets contain little fish oil (one to four percent), whereas pelagic fish can contain up to 30 percent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vagrancy (biology)
Vagrancy is a phenomenon in biology whereby an individual animal (usually a bird) appears well outside its normal range (biology), range; they are known as vagrants. The term accidental is sometimes also used. There are a number of poorly understood factors which might cause an animal to become a vagrant, including internal causes such as navigatory errors (endogenous vagrancy) and external causes such as severe weather (exogenous vagrancy). Vagrancy events may lead to colonisation and eventually to speciation. Birds In the Northern Hemisphere, adult birds (possibly inexperienced younger adults) of many species are known to continue past their normal breeding range during their spring migration and end up in areas further north (such birds are termed spring overshoots). In autumn, some young birds, instead of heading to their usual wintering grounds, take "incorrect" courses and migrate through areas which are not on their normal migration path. For example, Siberian passeri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Standard Length
Fish measurement is the measuring of individual fish and various parts of their anatomies. These data are used in many areas of ichthyology, including taxonomy and fisheries biology. Overall length * Standard length (SL) is the length of a fish measured from the tip of the snout to the posterior end of the last vertebra or to the posterior end of the midlateral portion of the hypural plate. Simply put, this measurement excludes the length of the caudal (tail) fin. * Total length (TL) is the length of a fish measured from the tip of the snout to the tip of the longer lobe of the caudal fin, usually measured with the lobes compressed along the midline. It is a straight-line measure, not measured over the curve of the body. Standard length measurements are used with Teleostei (most bony fish), while total length measurements are used with Myxini (hagfish), Petromyzontiformes (lampreys), and (usually) Elasmobranchii (sharks and rays), as well as some other fishes.
