Dieidolycus
''Dieidolycus'' is a genus of marine ray-finned fishes belonging to the family Zoarcidae, the eelpouts. The genus comprises three species which are found in the western central Pacific, southeastern Pacific and Southern Oceans. Taxonomy ''Dieidolycus'' was first proposed as a monospecific genus in 1988 by the South Africa based American ichthyologist M. Eric Anderson when he described its type species ''Dieidolycus leptodermatus'', with its type locality given as south of South Georgia in the Scotia Sea at 55°01'-10'S, 39°55'-46'W, and from a depth of . This genus is classified within the , one of 4 subfamilies in the family Zoarcidae, the eelpouts. This genus is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lycodinae
Lycodinae is a subfamily of marine ray-finned fish belonging to the family Zoarcidae, the eelpouts. These eelpouts are found are in all the world's oceans, with a number of species being found off southern South America. Taxonomy Lycodinae was first proposed as a taxonomic grouping in 1861 by the American zoologist Theodore Gill. The subfamily is classified within the eelpout family, Zoarcidae part of the suborder Zoarcoidei within the order Scorpaeniformes. The name of the subfamily derives from its type genus, ''Lycodes'', which means "wolf-like" and refers to the then presumed close relationship of that taxon to the wolffish. Genera Lycodinae contains the following genera: Characteristics Lycodinae eelpouts have elongate heads and bodies, they have between 58 and 144 vertebrae. The branchiostegal membranes are typically attached to the isthmus, although not in ''Lycodapus''. Most have a wide bill slit but some in some species it is more restricted. The do not usually posses ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zoarcidae
The eelpouts are the ray-finned fish family (biology), family Zoarcidae. As the common name suggests, they are somewhat eel-like in appearance. All of the roughly 300 species are ocean, marine and mostly bottom-dwelling, some at great depths. Eelpouts are predominantly found in the Northern Hemisphere. The arctic, north pacific and north Atlantic oceans have the highest concentration of species, however species are found around the globe. They are conventionally placed in the "perciform" assemblage; in fact, the Zoarcoidei seem to be specialized members of the Gasterosteiformes-Scorpaeniformes group of Acanthopterygii. The largest member of the family is ''Zoarces americanus'', which may reach 1.1 m in length. Other notable genera include ''Lycodapus'' and ''Gymnelus''. Taxonomy The eelpout family was first proposed as the family Zoarchidae in 1839 by the English naturalist William John Swainson but the spelling was changed to Zoarcidae after the spelling of the genus Zoarces w ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Total 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.

Pectoral 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 ...

''Lycodes'' is a genus of Zoarcidae, zoarcid fish in the subfamily (biology), subfamily Lycodinae. It is the most species-rich genus in its family (biology), taxonomic family as well as in the Arctic Ocean and adjacent waters. They occupy both shallow waters and deeper waters down to 3000 meters. A few species can occur in brackish waters. Taxonomy ''Lycodes'' was first proposed as a monospecific genus in 1831 by the Danish zoologist Johan Reinhard when he Species description, described ''Lycodes vahlii'', which he described from off Greenland.

Scotia Sea
The Scotia Sea is a sea located at the northern edge of the Southern Ocean at its boundary with the South Atlantic Ocean. It is bounded on the west by the Drake Passage and on the north, east, and south by the Scotia Arc, an undersea ridge and island arc system supporting various islands. The sea sits atop the Scotia Plate. It is named after the expedition ship ''Scotia''. Many icebergs melt there. Location and description The Scotia Sea is the area of water between the Drake Passage, Tierra del Fuego, South Georgia, the South Sandwich Islands, the South Orkney Islands, and the Antarctic Peninsula. These island groups all sit atop the Scotia Arc, which frames the sea on the north, east, and south. The Scotia Sea covers an area around . About half of the sea stands above the continental shelf. History The sea was named about 1932 after the ''Scotia'', the expedition ship used in these waters by the Scottish National Antarctic Expedition (1902–04) under William S. Bruce. The ...
