Hypsagoninae
Hypsagoninae is a subfamily of marine ray-finned fishes belonging to the Family (biology), family Agonidae, part of the sculpin Superfamily (biology), superfamily Cottoidea. These fishes are found in the North Pacific Ocean. Taxonomy Hypsagoninae was first proposed as a taxonomic grouping in 1861 by the American zoologist Theodore Gill. Some workers have regarded the genus Agonomalus as synonymous with Hypsagonus and place the two remaining genera in the subfamily Percidinae which was also named by Gill in 1897. However, most authorities recognise the three genera and place them in the subfamily Hypsagoninae. The 5th edition of ''Fishes of the World'' classifies the Hypsagoninae within the family Agonidae, part of the superfamily Cottoidea, the sculpins. Genera Hypsagoninae contains following 3 genera: Characteristics Hypsagoninae sculpins typically have deep, laterally compressed bodies with a terminal mouth which has nearly equal jaws, The rear edge of the orbit is convex.

Agonidae
Agonidae is a family of small, bottom-dwelling, cold-water marine fish. Common names for members of this family include poachers, Irish lords, sea ravens, alligatorfishes, starsnouts, hooknoses, and rockheads. They are notable for having elongated bodies covered by scales modified into bony plates, and for using their large pectoral fins to move in short bursts. The family includes about 59 species in some 25 genera, some of which are quite widespread. The pelvic fins are nearly vestigial, typically consisting of one small spine and a few rays. The swim bladder is not present. At in length, the dragon poacher (''Percis japonica'') is the largest member of the family, while '' Bothragonus occidentalis'' is long as an adult; most are in the 20–30 cm range. Agonidae species generally feed on small crustaceans and marine worms found on the bottom. Some species camouflage Camouflage is the use of any combination of materials, coloration, or illumination for conce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, DC, in 1863 to work at the Smithsonian Institution. He catalogued mammals, fishes, and mollusks most particularly, although he maintained 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, DC. Fellow members frequently mocked him for his vanity. He was president of the American Asso ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Achille Valenciennes
Achille Valenciennes (9 August 1794 – 13 April 1865) was a French zoology, zoologist. Valenciennes was born in Paris, and studied under Georges Cuvier. His study of parasitic worms in humans made an important contribution to the study of parasitology. He also carried out diverse systematic classifications, linking fossil and current species. He worked with Cuvier on the 22-volume "''Histoire Naturelle des Poissons''" (Natural History of Fish) (1828–1848), carrying on alone after Cuvier died in 1832. In 1832, he succeeded Henri Marie Ducrotay de Blainville (1777–1850) as chair of ''Histoire naturelle des mollusques, des vers et des zoophytes'' at the Muséum national d'histoire naturelle. Early in his career, he was given the task of classifying animals described by Alexander von Humboldt (1769–1859) during his travels in the American tropics (1799 to 1803), and a lasting friendship was established between the two men. He is the binomial authority for many species of fish, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solomon Herzenstein
Solomon Markovich Herzenstein (; 1854 – August 7, 1894) was a Russian zoologist. Biography Herzenstein received a degree in natural sciences and mathematics from St. Petersburg University and was appointed as the custodian of the Zoological Museum of the Imperial Academy of Science in 1879 or 1880. He also supervised practical training at the University for Women. In 1880, 1884, and 1887, he was commissioned to travel to the Murman Coast of the Kola Peninsula to study the mollusks and fishes there. His work, "Materialy k Faunye Murmanskavo Berega i Byelavo Morya," which was published in the ''Trudy'' of the in 1885, became a standard reference. He co-wrote ''Zamyetki po Ikhtologii Basseina Ryeki Amura'' (1887) and ''Nauchnye Rezultaty Puteshestvi Przevalskavo'' (1888–91) with N. L. Varpakhovski. He also wrote ''Ryby'' (St. Petersburg, 1888-91), and published "Ichthyologische Bemerkungen" in the ' (1890-92). Species described * '' Acanthogobio guentheri'' (Herzenstein, ...

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. 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 of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five Borders of the oceans, oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean, or, depending on the definition, to Antarctica in the south, and is bounded by the continents of Asia and Australia in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), the Pacific Ocean is the largest division of the World Ocean and the hydrosphere and covers approximately 46% of Earth's water surface and about 32% of the planet's total surface area, larger than its entire land area ().Pacific Ocean .
