Pimelodidae
The Pimelodidae, commonly known as the long-whiskered catfishes, are a family of catfishes (order Siluriformes). Taxonomy The family Pimelodidae has undergone much revision. Currently, it contains about 30 genera and about 90 recognized and known but unnamed species. Wikipedia lists 109 species in this family. The low-eye catfish (previously family Hypophthalmidae), and thus the genus '' Hypophthalmus'', which contains four species, was reclassified with the pimelodids. This family previously included fish that are now classified under Pseudopimelodidae (previously subfamily Pseudopimelodinae) and Heptapteridae (previously subfamily Rhamdiinae). This family also previously included '' Conorhynchos conirostris'', currently ''incertae sedis''. However, a molecular analysis has shown unequivocal support for monophyly of the individual families and the genus ''Conorhynchos'' into a clade called Pimelodoidea, including Pimelodidae + Pseudopimelodidae and Heptapteridae + ''Conorhynch ...

Brachyplatystoma
''Brachyplatystoma'' is a genus of catfish from the family Pimelodidae sometimes collectively termed the goliath catfishes. As this common name indicates, this genus includes some of the largest species of catfish, including the piraíba, ''B. filamentosum'', which reaches up to in length; though the other species (and indeed most individuals of ''B. filamentosum'') don't reach this length. ''Brachyplatystoma'' are found in the Amazon and Orinoco basins, and other tropical freshwater and brackish habitats in South America. All species are migratory, which makes them important as food fish across their wide range. Some are also kept as aquarium fish. Classification ''Brachyplatystoma'' is derived from the Greek words '' brachy'', '' platy'', and ''stoma'', which mean "short", "flat", and "mouth", respectively. This genus was described in 1862 by Pieter Bleeker. ''Brachyplatystoma'' and its monotypic sister species '' Platynematichthys'' are the only genera in the tribe B ...

Sorubimichthys
The firewood catfish (''Sorubimichthys planiceps'') is a species of South American pimelodid catfish, the sole member of the genus ''Sorubimichthys''. Firewood catfish are one of the hundreds of freshwater fish in the Amazon Basin that play important ecological and economic roles. Known by locals along the Amazon Basin as ''peixe-lenha'', the firewood catfish is so called because it is of little eating value and is often dried and used for firewood. Firewood catfish are imported to areas outside their native range as in-demand aquarium fish. Description The largest recorded specimen of adult firewood catfish was reported at in standard length (a measurement from the tip of the snout to the posterior end of the last vertebrae). Juveniles have been measured ranging from , and other adult specimens have been measured ranging from . Juveniles Standard adult and subadult appearance includes a flat head (the species name, '' planiceps'', comes from the Latin for flathead or flat- ...

Sorubim
''Sorubim'' is a small genus of long-whiskered catfish native to tropical South America. A number of characteristics allows the differentiation of each species in the genus. ''Sorubim'' species are important food fish in South America and are highly significant to fisheries of some areas; however, harvests of these fish are not identified as much as other, more popular food fishes such as ''Colossoma'', ''Arapaima'', and ''Brachyplatystoma''. Some species of this family are popular aquarium fish. Taxonomy The genus name is derived from a Brazilian local name, ''sorubí''.Littman, M.W. (2007): page 4 The description of ''Sorubim'' has been attributed to both Cuvier and Agassiz in 1829, but because Cuvier's description predates that of Agassiz by two months, Cuvier's is valid. Later, ''Sorubim lima'', originally described as ''Siluris lima'' in 1801, was designated as the type species by Bleeker in 1862.Littman, M.W. (2007): page 2 In 2007, this genus was reviewed, validating five ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pseudoplatystoma
''Pseudoplatystoma'' is a genus of several South American catfish species of family Pimelodidae. The species are known by a number of different common names. They typically inhabit major rivers where they prefer the main channels and tend to stay at maximum depth, but some species can also be seen in lakes, flooded forests, and other freshwater habitats. They have robust bodies, and are important food fish. Recently, their population size has been on the drastic decline due to a variety of factors including overfishing and habitat destruction due to the construction of hydroelectric dams. Nomenclature ''Pseudoplatystoma'' is a monophyletic genus of catfishes. ''P. fasciatum'' was the first species to be described, under the name ''Siluris fasciatus''. In 1829, ''P. corruscans'' was described under the name ''Platystoma corruscans'', and over a decade later, ''P. tigrinum'' was described as ''Platystoma tigrinum''. In 1862, ''Pseudoplatystoma'' was described and these species t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Platynematichthys
''Platynematichthys notatus'', the coroatá or striped catfish, is a species of catfish (order Siluriformes) of the monotypic genus ''Platynematichthys'' of the family Pimelodidae. It is native to the Amazon and Orinoco Basins in South America. In the Orinoco this distinctly spotted species reaches up to in standard length, but it reportedly only reaches about half that size in the Amazon. ''Platynematichthys'' and its sister group '' Brachyplatystoma'' are the only genera in the tribe Brachyplatystomatini. These two genera are characterized by two synapomorphies; these include a gas bladder divided into an anterior portion and a triangular posterior portion, as well as a ventral crest under the cleithrum, the main bone supporting the pectoral fin Fins are moving appendages protruding from the body of fish that interact with water to generate thrust and help the fish aquatic locomotion, swim. Apart from the tail or caudal fin, fish fins have no direct connection with the v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pinirampus
''Pinirampus pirinampu'' is a species of catfish (order Siluriformes) of the family Pimelodidae. ''P. pirinampu'' is also known as the flatwhiskered catfish. Taxonomy This species was first described as ''Pimelodus barbancho''; however, this is considered a ''nomen oblitum''. It was then described as ''Pimelodus pirinampu'' in 1829. In 1858, the genus ''Pinirampus'' was described for this species, in which it is usually classified as the only species. However, '' Megalonema argentinum'' has sometimes been considered a part of this genus. Distribution This species is found in the Amazon, Essequibo, Orinoco, and Paraná basins. Description ''P. pirinampu'' may reach a length of and an average weight of . This species has a maximum published weight of . These fish reach sexual maturity at just under in length.

Platystomatichthys
''Platystomatichthys sturio'' is the only species in the genus ''Platystomatichthys'' of the catfish (order Siluriformes) family Pimelodidae. It is sometimes called the sturgeon catfish. This species occurs in the Amazon Basin and reaches a length of about TL. ''Platystomatichthys'' is classified under the "'' Calophysus-Pimelodus'' clade". Within this clade, it is considered a part of the "Pimelodus-group" of Pimelodids, which also includes ''Pimelodus'', '' Exallodontus'', '' Duopalatinus'', ''Cheirocerus'', '' Iheringichthys'', '' Bergiaria'', '' Bagropsis'', ''Parapimelodus ''Parapimelodus'' is a small genus of long-whiskered catfishes native to South America.

Steindachneridion
''Steindachneridion'' is a genus of South American pimelodid catfish (order Siluriformes). Taxonomy The first species of the genus, ''S. parahybae'', was described in 1877 by Franz Steindachner under the name ''Platystoma parahybae''. Later, Carl H. Eigenmann and Rosa Smith Eigenmann described ''Steindachneridia'', named for Steindachner, for this species and for ''S. amblyurum'' (designated as the type species) in 1888. The next year, Eigenmann and Eigenmann described ''S. doceanum''. In 1918, Miranda Ribeiro described ''S. scriptum'' and ''S. scriptum punctatum''; later, ''S. punctatum'' was studied and considered to be a species of its own. However, because ''Steindachneria'' was already being used, these fish were transferred to ''Steindachneridion'' in 1919. The most recent species, ''S. melanodermatum'', was described by Garavello in 2005. This genus currently includes six extant species. Two fossil species of ''Steindachneridion'' have been found. The first to be describ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Propimelodus
''Propimelodus'' is a genus of South American catfish of the family Pimelodidae. Taxonomy The type species of this genus, ''P. eigenmanni'', was first described in 1946 under the genus ''Pimelodus''. In 2002, the genus ''Propimelodus'' was described for this species. Shortly after, in 2006, the species ''P. caesius'' was described to this genus and in 2007 another new species, ''P. araguayae'' was described. Other species will be described in the future. ''Propimelodus'' is classified under the "'' Calophysus-Pimelodus'' clade".
