Taractes
''Taractes'' is a genus of marine ray-finned fishes from the family Bramidae, the pomfrets. ''Taractes'' can be distinguished from other bramid genera but having a flat, or slightly curved profile, between the eyes (unlike the definitive arched profile present in the other genera) and by having scales on both the dorsal and anal fins (unlike ''Pterycombus '' and ''Pteraclis'' which lack these scales). Species There are currently two recognized species in this genus: * '' Taractes asper'' R. T. Lowe, 1843 (Rough pomfret) * '' Taractes rubescens'' ( D. S. Jordan & Evermann, 1887) (Pomfret) These two species are easily distinguished from one another as adults. Adult ''T. rubescens'' develop a dense, bony keel on the caudal peduncle that is thought to be composed of enlarged, fused scales, which are absent in ''T. asper''. Additionally, adult ''T. rubescens'' lack a noticeable lateral line, which is typically present in adult ''T. asper''. Distribution The genus is widely distri ...

Taractes Rubescens
''Taractes rubescens'', the pomfret, keeltail pomfret, knifetail pomfret or black pomfret, is a species of marine ray-finned fish, a pomfret of the family Bramidae. ''T. rubescens'' is closely related, and quite similar, to '' Taractes asper'', but adults can most easily be distinguished by the bony keel present on the caudal peduncle. In fact, this bony keel is unique to ''Taractes rubescens'' and will distinguish it from all other bramids. Diet ''T. rubescens'' have a varied diet consisting of marine invertebrates (including decapods and cephalopods) and, presumably, small fishes. Habitat and Ecology As with most bramids,''T. rubescens'' are epi- mesopelagic fish that are typically found at depths between 0-600m. They are highly migratory and believed to be solitary. They are frequently found in the stomachs of large pelagic predator fishes, including billfish and tuna, suggesting that they play an important role in the diets of fast swimming, predatory fishes.

Pomfret
Pomfrets are perciform fishes belonging to the family Bramidae. The family currently includes 20 species across seven genera. Several species are important food sources for humans, especially ''Brama brama'' in South Asia. The earlier form of the pomfret's name was "", a word which probably ultimately comes from Portuguese ''pampo'', referring to various fish such as the blue butterfish (''Stromateus fiatola''). The fish meat is white in color. Distribution They are found globally in the Atlantic, Indian, and Pacific Oceans, as well as numerous seas including the Norwegian, Mediterranean, and Sea of Japan. Nearly all species can be found in the high seas. However, fishes in the genera '' Pterycombus'' and '' Pteraclis'' tend to be found off continental shelves. Further, fishes in the genus '' Eumegistus'' are hypothesized to be largely benthic and found to occupy deep water shelves. Some species of pomfrets are also known as monchong, specifically in Hawaiian cuisine. Gen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Richard Thomas Lowe
Richard Thomas Lowe (1802–1874) was an English scientist, a botanist, ichthyologist, malacologist, and a clergyman. In 1825 he graduated from Christ's College, Cambridge, and in the same year he took holy orders. In 1832 he became a clergyman in the Madeira Islands, where he was also a part-time naturalist, extensively studying the local flora and fauna. He wrote a book on the Madeiran flora. He died in 1874 when the ship he was on was wrecked off the Isles of Scilly. Taxa Lowe named and described numerous molluscan taxa, including: * ''Caseolus'', a land snail genus and eight species within it * ''Lemniscia'', a land snail A land snail is any of the numerous species of snail that live on land, as opposed to the sea snails and freshwater snails.

David Starr Jordan
David Starr Jordan (January 19, 1851 – September 19, 1931) was the founding president of Stanford University, serving from 1891 to 1913. He was an ichthyologist during his research career. Prior to serving as president of Stanford University, he had served as president of Indiana University from 1884 to 1891. Starr was also a strong supporter of eugenics, and his published views expressed a fear of "race-degeneration" and asserted that cattle and human beings are "governed by the same laws of selection". He was an antimilitarist since he believed that war killed off the best members of the gene pool, and he initially opposed American involvement in World War I. Early life and career Jordan was born in Gainesville, New York, and grew up on a farm in upstate New York. His parents made the unorthodox decision to educate him at a local girls' high school. His middle name, Starr, does not appear in early census records, and was apparently self-selected; he had begun using ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barton Warren Evermann
Barton Warren Evermann (October 24, 1853 – September 27, 1932) was an American ichthyologist. Early life and education Evermann was born in Monroe County, Iowa in 1853. His family moved to Indiana while he was still a child and it was there that he grew up, completed his education, and married. Evermann graduated from Indiana University in 1886. Career For 10 years, he served as teacher and superintendent of schools in Indiana and California. While teaching in Carroll County, Indiana Evermann met fellow teacher Meadie Hawkins. They married on October 24, 1875 and had a son, Toxaway Bronte (born 1879) and a daughter, Edith (born). He was professor of biology at the Indiana State University in Terre Haute from 1886 to 1891. He lectured at Stanford University in 1893–1894, at Cornell University in 1900–1903, and at Yale University in 1903–1906.

Louis Roule
Louis Roule (; 20 December 1861 – 30 July 1942) was a French zoologist born in Marseille. In 1881 he obtained a degree in natural sciences at Marseille, followed by his doctorate of sciences (1884) at Paris with a thesis on ascidians of coastal Provence. From 1885 he worked as a lecturer at the faculty of sciences in Toulouse, where in 1892 he became a professor. During the previous year (1891), he earned a doctorate in medicine. In 1910 he succeeded Léon Vaillant (1834–1914) as chair of zoology (reptiles and fish) at the Muséum national d'histoire naturelle in Paris, a position he would hold until 1937. During this time period he was also an instructor at the Institut National Agronomique (from 1925), and director of the laboratory of ichthyology at the École pratique des hautes études (EPHE). Works Roule's early research dealt largely with invertebrates. Later his focus turned to ichthyology, of which he had the opportunity to take inventory of large collections of mari ...

Genus
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 cl ...

Ray-finned Fish
Actinopterygii (; ), members of which are known as ray-finned fishes, is a class of bony fish. They comprise over 50% of living vertebrate species. The ray-finned fishes are so called because their fins are webs of skin supported by bony or horny spines (rays), as opposed to the fleshy, lobed fins that characterize the class Sarcopterygii (lobe-finned fish). These actinopterygian fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the link or connection between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). By species count, actinopterygians dominate the vertebrates, and they constitute nearly 99% of the over 30,000 species of fish. They are ubiquitous throughout freshwater and marine environments from the deep sea to the highest mountain streams. Extant species can range in size from ''Paedocypris'', at , to the massive ocean sunfish, at , and the long-bodied oarfish, at . The vast majority of Actino ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opin ...

Pterycombus
''Pterycombus'' is a genus of pomfret distinguished by greatly elongated dorsal and anal fins. Along with the genus '' Pteraclis'', these fishes are commonly referred to as fanfishes. ''Pterycombus'' can be distinguished from ''Pteraclis'' by examining the dorsal and anal fin rays, which should be relatively uniform in thickness to neighboring rays and by a lack of scales anterior to the dorsal fin. Species Currently, there are two recognized species in this genus: * '' Pterycombus brama'', Atlantic fanfish (Fries, 1837) * '' Pterycombus petersii'', prickly fanfish ( Hilgendorf, 1878) Species Distinction ''Pterycombus brama'' can be distinguished from ''Pterycombus petersii'' by measuring the length of the longest dorsal and anal fin rays. In ''P. brama'', the longest ray will be greater than half standard length, but will be less than half standard length in ''P. petersii''. These two species can also be distinguished by geographic location. ''P. brama'' is generally distribute ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pteraclis
''Pteraclis'' is a genus of fish in the family Bramidae, the pomfrets. They are known commonly as fanfishes. The three species are distributed throughout the oceans of the world. Species Species include: * '' Pteraclis aesticola'' ( D. S. Jordan & Snyder, 1901) – Pacific fanfish * '' Pteraclis carolinus'' Valenciennes, 1833 – fanfish * '' Pteraclis velifera'' (Pallas Pallas may refer to: Astronomy * 2 Pallas asteroid ** Pallas family, a group of asteroids that includes 2 Pallas * Pallas (crater), a crater on Earth's moon Mythology * Pallas (Giant), a son of Uranus and Gaia, killed and flayed by Athena * Pa ..., 1770) – spotted fanfish References Bramidae {{Perciformes-stub ...
