Brosmophycinae
Brosmophycinae is a subfamily of the viviparous brotulas. They are divided from the subfamily Bythitinae by having the dorsal fin, caudal fin and anal fin all separate whereas they are joined in the Bythitinae. It is divided into the tribes Dinematichthyini and Brosmophycini, with the first having hardened genital claspers and the second soft genital claspers. A review in 2016 elevated the Dinematichthyini to the status of a family Family (from la, familia) is a Social group, group of people related either by consanguinity (by recognized birth) or Affinity (law), affinity (by marriage or other relationship).

Dinematichthyini
Dinematichthyini is a tribe of viviparous brotulas, which is conventionally placed within the subfamily Brosmophycinae. They are differentiated from the other tribe within that subfamily, the Brosmophycinae , by having a single pair of ossified genital claspers, having an absence or greatly reduced scales on the head and having the posterior end of the maxillary bone showing a small amount of vertical expansion. A review of the viviparous brotulas carried out in 2016 elevated the tribe to a family, the Dinematichthyidae. Abstract Genera The following genera are included in the tribe Dinematichthyini: * ''Alionematichthys'' * ''Beaglichthys'' * ''Brosmolus'' * ''Brotulinella'' * ''Dactylosurculus'' * ''Dermatopsis'' * ''Dermatopsoides'' * '' Diancistrus'' * ''Didymothallus'' * ''Dinematichthys'' * ''Dipulus'' * ''Gunterichthys'' * ''Lapitaichthys'' * '' Majungaichthys'' * '' Mascarenichthys'' * ''Monothrix'' * '' Nielsenichthys'' * ''Ogilbia'' * '' Ogilbichthys'' * ''Paradiancist ...

Viviparous Brotula
The viviparous brotulas form a family, the Bythitidae, of ophidiiform fishes.

Brosmophycini
Brosmophycini is a tribe of viviparous brotula, one of two tribes in the subfamily Brosmophycinae. They are distinguished from the other brosmophycin tribe, the Dinematichthyini, by having a male intromittent organ which has no ossified parts, a scale-covered body and well developed gill rakers. Genera The following genera are classified as being members of the tribe Brosmophycini: * '' Bidenichthys'' * '' Brosmodorsalis'' * '' Brosmophyciops'' * ''Brosmophycis'' * '' Eusurculus'' * ''Fiordichthys'' * ''Lucifuga ''Lucifuga'' is a genus of viviparous brotulas.

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] |
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 ...

Bythitinae
Bythitinae is a subfamily of viviparous brotulas, one of the two subfamilies in the family Bythitidae. This subfamily is characterised by having the dorsal, caudal and anal fins combined. They are mostly found in temperate to tropical seas, from reefs to the benthopelagic zone, but some species from the North Atlantic Ocean occur in into Arctic waters. Genera The following genera are included in the subfamily Bythininae: * '' Acarobythites'' * ''Anacanthobythites'' * '' Bellottia'' * '' Bythites'' * '' Calamopteryx'' * '' Cataetyx'' * '' Diplacanthopoma'' * ''Ematops'' * ''Grammonus'' * ''Hastatobythites'' * ''Hephthocara'' * ''Microbrotula'' * '' Parasaccogaster''Nielsen, J.G., Schwarzhans, W. & Cohen, D.M.

Dorsal Fin
A dorsal fin is a fin located on the back of most marine and freshwater vertebrates within various taxa of the animal kingdom. Many species of animals possessing dorsal fins are not particularly closely related to each other, though through convergent evolution they have independently evolved external superficial fish-like body plans adapted to their marine environments, including most numerously fish, but also mammals such as cetaceans (whales, dolphins, and porpoises), and even extinct ancient marine reptiles such as various known species of ichthyosaurs. Most species have only one dorsal fin, but some have two or three. Wildlife biologists often use the distinctive nicks and wear patterns which develop on the dorsal fins of large cetaceans to identify individuals in the field. The bony or cartilaginous bones that support the base of the dorsal fin in fish are called ''pterygiophores''. Functions The main purpose of the dorsal fin is to stabilize the animal against rollin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Tribe (biology)
In biology, a tribe is a taxonomic rank above genus, but below family and subfamily. It is sometimes subdivided into subtribes. By convention, all taxonomic ranks from genus upwards are capitalized, including both tribe and subtribe. In zoology, the standard ending for the name of a zoological tribe is "-ini". Examples include the tribes Caprini (goat-antelopes), Hominini (hominins), Bombini (bumblebees), and Thunnini (tunas). The tribe Hominini is divided into subtribes by some scientists; subtribe Hominina then comprises "humans". The standard ending for the name of a zoological subtribe is "-ina". In botany, the standard ending for the name of a botanical tribe is "-eae". Examples include the tribes Acalypheae and Hyacintheae. The tribe Hyacintheae is divided into subtribes, including the subtribe Massoniinae. The standard ending for the name of a botanical subtribe is "-inae". In bacteriology, the form of tribe names is as in botany, e.g., Pseudomonadeae, based on the ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
