Isorineloricaria Villarsi
''Isorineloricaria villarsi'' is a species of catfish in the family Loricariidae. It is native to South America, where it is known only from Venezuela. The species reaches 32 cm (12.6 inches) in standard length and is believed to be a facultative air-breather. ''Isorineloricaria villarsi'' was originally described as a member of ''Plecostomus'' by Christian Frederik Lütken in 1874, although it was subsequently transferred to '' Hypostomus'' after ''Plecostomus'' was found to be an invalid genus. It was later classified within the now-invalid genus ''Squaliforma'', although a 2016 taxonomic review of the genera ''Aphanotorulus'' and '' Isorineloricaria'' conducted by Jonathan W. Armbruster (of Auburn University) and C. Keith Ray found it to be a member of ''Isorineloricaria''.Ray, C. K., & Armbruster, J. W. (2016).

Christian Frederik Lütken
Christian Frederik Lütken (; 7 October 1827, in Sorø – 6 February 1901), was a Denmark, Danish zoologist and naturalist. In 1852, he resigned his commission as a lieutenant with the Danish army, and earned his master's degree in sciences the following year.Darwinarkivet.dk Christian Frederik Lütken (1827-1901) Afterwards, he served as an assistant to Japetus Steenstrup (1813–1897) at the University of Copenhagen Zoological Museum, at the time an independent institution, now part of the University of Copenhagen Botanical Garden, Natural History Museum of Denmark. Following Steenstrup's retirement in 1885, he became a professor of zoology and director of the zoological museum. As he grew older, he suffered from physical infirmities and during the last year of his life, he was strick ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Catfish
Catfish (or catfishes; order Siluriformes or Nematognathi) are a diverse group of ray-finned fish. Named for their prominent barbels, which resemble a cat's whiskers, catfish range in size and behavior from the three largest species alive, the Mekong giant catfish from Southeast Asia, the wels catfish of Eurasia, and the piraíba of South America, to detritivores (species that eat dead material on the bottom), and even to a tiny parasitic species commonly called the candiru, ''Vandellia cirrhosa''. Neither the armour-plated types nor the naked types have scales. Despite their name, not all catfish have prominent barbels or "whiskers". Members of the Siluriformes order are defined by features of the skull and swimbladder. Catfish are of considerable commercial importance; many of the larger species are farmed or fished for food. Many of the smaller species, particularly the genus ''Corydoras'', are important in the aquarium hobby. Many catfish are nocturnal, [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Loricariidae
The Loricariidae is the largest family of catfish (order Siluriformes), with 92 genera and just over 680 species. Loricariids originate from freshwater habitats of Costa Rica, Panama, and tropical and subtropical South America. These fish are noted for the bony plates covering their bodies and their suckermouths. Several genera are sold as " plecos", notably the suckermouth catfish, ''Hypostomus plecostomus'', and are popular as aquarium fish. Common names Members of the family Loricariidae are commonly referred to as loricariids, suckermouth armoured catfishes, or armoured catfish. The name "plecostomus", and its shortened forms "pleco" and "plec", are used for many Loricariidae, since ''Plecostomus plecostomus'' (now called ''Hypostomus plecostomus'') was one of the first loricariid species imported for the fish-keeping hobby. Some loricariids are not normally considered "plecostomus", such as ''Farlowella'' catfish. In their native range, these fish are known as ''cascudos'' ...

South America
South America is a continent entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a relatively small portion in the Northern Hemisphere at the northern tip of the continent. It can also be described as the southern subregion of a single continent called America. South America is bordered on the west by the Pacific Ocean and on the north and east by the Atlantic Ocean; North America and the Caribbean Sea lie to the northwest. The continent generally includes twelve sovereign states: Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Guyana, Paraguay, Peru, Suriname, Uruguay, and Venezuela; two dependent territories: the Falkland Islands and South Georgia and the South Sandwich Islands; and one internal territory: French Guiana. In addition, the ABC islands of the Kingdom of the Netherlands, Ascension Island (dependency of Saint Helena, Ascension and Tristan da Cunha, a British Overseas Territory), Bouvet Island ( dependency of Norway), Pa ...

Fish Measurement
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. Total length meas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hypostomus
''Hypostomus'' is a genus of catfish in the family Loricariidae. They are native to tropical and subtropical South America. '' H. plecostomus'' is the popular freshwater aquarium fish formerly known as ''Plecostomus plecostomus''. The taxonomic structure of the Loricariidae is still being expanded by scientists. ''Hypostomus'' is a highly species-rich and widely distributed catfish genus. [Baidu] |
Aphanotorulus
''Aphanotorulus'' is a genus of armored catfishes native to the Amazon, Orinoco, Essequibo and Jaguaribe basins in South America.Ray, C.K. & Armbruster, J.W. (2016): The genera ''Isorineloricaria'' and ''Aphanotorulus'' (Siluriformes: Loricariidae) with description of a new species. ''Zootaxa, 4072 (5): 501–539.'' They typically occur on a sand or gravel bottom in slow to moderately flowing rivers and streams, but some species occur in areas with fast current. The largest species in the genus reaches up to in standard length. Taxonomy The taxonomy of this genus has been a matter of dispute, all having been placed in '' Hypostomus'' in the past, and some occasionally placed in ''Squaliforma''. ''Squaliforma'' is now regarded as a synonym of ''Aphanotorulus'', but species west of the Andes have been moved to '' Isorineloricaria''. There are currently 7 recognized species of ''Aphanotorulus'': * ''Aphanotorulus ammophilus'' Armbruster & Page, 1996 * ''Aphanotorulus emarg ...
