Stichaeinae
Stichaeinae is a subfamily of marine ray-finned fishes, Taxonomy (biology), classified within the family Stichaeidae, the pricklebacks or shannies. These fishes are found in the North Pacific, Arctic and North Atlantic Oceans. Taxonomy Stichaeinae contains the type taxon of the family Stichaeidae, the Arctic shanny (''Stichaeus punctatus''), and the name is based on Theodore Gill’s 1864 name for the family. The name of the subfamily comes from that of its type genus ''Stichaeus'', which means “set in a row”, which may be an allusion to the row of black spots on the dorsal fin, dorsal fins of the species in that genus. Genera Stichaeinae contains the following genera: ''Dinogunellus'' Solomon Herzenstein, Herzenstein, 1890 is treated as a vaild genus by ''Catalog of Fishes'' but ''Fishbase'' does not and treats the 3 species classified within it as belonging to the genus ''Stichaeus''.

Stichaeus Nozawae
''Stichaeus'' is a genus of marine ray-finned fishes belonging to the family Stichaeidae, the pricklebacks or shannies. These fishes are mainly found in the North Pacific Ocean with one species in the Arctic and western North Atlantic Oceans. Taxonomy ''Stichaeus'' was first proposed as a monospecific genus in 1836 by the Danish zoologist Johan Reinhardt with ''Blennius punctatus'', which was described by Johan Christian Fabricius in 1780 from western Greenland, designated as the type species. This genus is classified within the subfamily Stichaeinae of the Zoarcoid family Stichaeidae. Species ''Stichaeus'' contains 6 extant species and 2 known extinct species, as follows: † means extinct Etymology The genus name, ''Stichaeus'' means "to set in a row", and is presumed to refer to the row of 5 or 6 circular spots on the dorsal fin.

Stichaeidae
Stichaeidae, the pricklebacks or shannies, are a family of marine ray-finned fishes in the suborder Zoarcoidei of the order Scorpaeniformes. Most species are found in the North Pacific Ocean with a few in the North Atlantic Ocean. Taxonomy Stichaeidae was first proposed as a family in 1864 by the American zoologist Theodore Gill, although he called it the Stichaeoidae. The 5th edition of ''Fishes of the World'' classifies this family within the suborder Zoarcoidei, within the order Scorpaeniformes. Other authorities classify this family in the infraorder Zoarcales wihin the suborder Cottoidei of the Perciformes because removing the Scorpaeniformes from the Perciformes renders that taxon non monophyletic. ''Fishes of the World'' mentions six subfamilies but does not assign genera to the subfamilies while other authorities split the Cebidichthyidae, Opisthocentridae, Lumpenidae and Neozoarcidae from the Sitchaeidae as valid families.

Arctic Shanny
The Arctic shanny (''Stichaeus punctatus'') is a species of marine ray-finned fish belonging to the family Stichaeidae, the pricklebacks and shannies. This species occurs in the North Pacific, Arctic and western North Atlantic Oceans. Taxonomy The Arctic shanny was first formally described in 1780 as ''Blennius punctatus'' by the Danish zoologist Johan Christian Fabricius, giving its type locality as Western Greenland. When Johan Reinhardt proposed the genus '' Stichaeus'' he designated ''Blennius punctatus'' as its type species. The specific name ''punctatus'' means spotted, a reference to the 5 or 6 spots on the dorsal fin. Subspecies Some authorities recognise two subspecies of the Arctic shanny: The nominate subspecies is found in the northern western Atlantic and Pacific Oceans and is sympatric with ''S.p. pulcherrimus'' in the Sea of Okhtosk and this subspecies may be a valid, distinct species.

Taxonomy (biology)
In biology, taxonomy () is the scientific study of naming, defining ( circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxa (singular: taxon) and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain, kingdom, phylum (''division'' is sometimes used in botany in place of ''phylum''), class, order, family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, as he developed a ranked system known as Linnaean taxonomy for categorizing organisms and binomial nomenclature for naming organisms. With advances in the theory, data and analytical technology of biological systematics, the Linnaean system has transformed into a system of modern biological classification intended to reflect the evolu ...

Anal 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 ...

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.

Theodore Gill
Theodore Nicholas Gill (March 21, 1837 – September 25, 1914) was an American ichthyologist, mammalogist, malacologist and librarian. Career Born and educated in New York City under private tutors, Gill early showed interest in natural history. He was associated with J. Carson Brevoort in the arrangement of the latter's entomological and ichthyological collections before going to Washington D.C. in 1863 to work at the Smithsonian Institution. He catalogued mammals, fishes and mollusks most particularly although maintaining proficiency in other orders of animals. He was librarian at the Smithsonian and also senior assistant to the Library of Congress. He was elected as a member of the American Philosophical Society in 1867. Gill was professor of zoology at George Washington University. He was also a member of the Megatherium Club at the Smithsonian Institution in Washington, D.C. Fellow members frequently mocked him for his vanity. He was president of the American Associati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genera
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below 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 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 of an ancestral taxon are grouped together (i.e. phylogenetic analysis should clearly demons ...
