Psilorhynchus
''Psilorhynchus'' is a genus of ray-finned fish in the family Psilorhynchidae native to South Asia. This genus is the only member of its family. The members of ''Psilorhynchus'' are small benthic fishes which occur in rivers and streams with fast to swift currents, hence they are often referred to as torrent minnows. They are distributed in southern Asia, in the Indo-Burma region and the Western Ghats. The genus is the sister group to the family Cyprinidae, and with that family the Psilorhynchidae makes up the superfamily Cyprinoidea, with all the other cypriniform families in the superfamily Cobitoidea. Species There are currently 33 recognized species in this genus: * '' Psilorhynchus amplicephalus'' Arunachalam, Muralidharan & Sivakumar, 2007 * '' Psilorhynchus arunachalensis'' ( Nebeshwar, Bagra & D. N. Das, 2007) * '' Psilorhynchus balitora'' (Hamilton, 1822) * '' Psilorhynchus bichomensis'' Shangningam, Kosygin & Gopi, 2019 * '' Psilorhynchus brachyrhynchus'' Co ...

Francis Hamilton Buchanan
Francis Buchanan (15 February 1762 – 15 June 1829), later known as Francis Hamilton but often referred to as Francis Buchanan-Hamilton, was a Scottish surgeon, surveyor and botanist who made significant contributions as a geographer and zoologist while living in India. He did not assume the name of Hamilton until three years after his retirement from India. The standard botanical author abbreviation Buch.-Ham. is applied to plants and animals he described, though today the form "Hamilton, 1822" is more usually seen in ichthyology and is preferred by Fishbase. Early life Francis Buchanan was born at Bardowie, Callander, Perthshire where Elizabeth, his mother, lived on the estate of Branziet; his father Thomas, a physician, came in Spittal and claimed the chiefdom of the name of Buchanan and owned the Leny estate. Francis Buchanan matriculated in 1774 and received an MA in 1779. As he had three older brothers, he had to earn a living from a profession, so Buchanan studied med ...

Cyprinidae
Cyprinidae is a family of freshwater fish commonly called the carp or minnow family, including the carps, the true minnows, and their relatives the barbs and barbels, among others. Cyprinidae is the largest and most diverse fish family, and the largest vertebrate animal family overall, with about 1,780 species divided into 166 valid genera. Cyprinids range from about in size to the giant barb (''Catlocarpio siamensis''). By genus and species count, the family makes up more than two-thirds of the ostariophysian order Cypriniformes. The family name is derived from the Greek word ( 'carp'). Biology and ecology Cyprinids are stomachless, or ''agastric'', fish with toothless jaws. Even so, food can be effectively chewed by the gill rakers of the specialized last gill bow. These pharyngeal teeth allow the fish to make chewing motions against a chewing plate formed by a bony process of the skull. The pharyngeal teeth are unique to each species and are used to identify spec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Loach
Loaches are ray-finned fishes of the suborder Cobitoidei. They are freshwater, benthic (bottom-dwelling) fish found in rivers and creeks throughout Eurasia and North Africa, northern Africa. Loaches are among the most diverse groups of fish; the 1249 known species of Cobitoidei comprise about 107 genus, genera divided among 9 family (biology), families. Etymology The name Cobitoidei comes from the type genus, ''Cobitis'', described by Carl Linnaeus in his landmark 1758 10th edition of Systema Naturae, 10th edition of ''Systema Naturae''. However, its origin predates modern zoological nomenclature and derives from a term used by Aristotle to refer to "small fishes that bury... like the Gudgeon (fish), gudgeon." Description Loaches display a wide variety of morphologies, making the group difficult to characterize as a whole using external traits. They range in adult length from the 23 mm (1 in) miniature eel-loach, ''Pangio longimanus'', to the 50 cm (20 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Benthic
The benthic zone is the ecological region at the lowest level of a body of water such as an ocean, lake, or stream, including the sediment surface and some sub-surface layers. The name comes from the Ancient Greek word (), meaning "the depths". Organisms living in this zone are called benthos and include microorganisms (e.g., bacteria and fungi) as well as larger invertebrates, such as crustaceans and polychaetes. Organisms here, known as bottom dwellers, generally live in close relationship with the substrate and many are permanently attached to the bottom. The benthic boundary layer, which includes the bottom layer of water and the uppermost layer of sediment directly influenced by the overlying water, is an integral part of the benthic zone, as it greatly influences the biological activity that takes place there. Examples of contact soil layers include sand bottoms, rocky outcrops, coral, and bay mud. Description Oceans The benthic region of the ocean begins at the ...
