Pseudobunocephalus
''Pseudobunocephalus'' is a genus of banjo catfishes. Taxonomy The species of ''Pseudobunocephalus'' were originally classified in the genus ''Bunocephalus'', but after further study it was found that these fish were unrelated to the type species ''Bunocephalus verrucosus'' or any of the other existing aspredinid genera. Thus, a new genus was described in 2008. ''Pseudobunocephalus'' is the most basal genus in the family, and represents the sister group to all other Aspredinidae. ''P. lundbergi'' is also the most basal species and is the sister taxon to the rest of the species in the genus. Species There are currently six species in this genus: *''Pseudobunocephalus amazonicus'' ( Mees, 1989) *''Pseudobunocephalus bifidus'' ( C. H. Eigenmann, 1942) *''Pseudobunocephalus iheringii'' ( Boulenger, 1891) *''Pseudobunocephalus lundbergi'' Friel, 2008 *''Pseudobunocephalus quadriradiatus'' ( Mees, 1989) *''Pseudobunocephalus rugosus'' ( C.

Aspredinidae
The Aspredinidae are a small South American family of catfishes ( order Siluriformes) also known as the banjo catfishes, with about 43 species. Distribution Aspredinids are found throughout the major tropical rivers of South America (e.g., Magdalena, Orinoco, Amazon, São Francisco, Paraguay- Paraná, and Uruguay). ''Bunocephalus'' is the only genus found in rivers west of the Andes including the Atrato, San Juan, and Patía Rivers. Taxonomy Of the 13 genera in the family Aspredinidae, a few genera have been described relatively recently, including '' Acanthobunocephalus'' in 1995, '' Micromyzon'' in 1996, and '' Pseudobunocephalus'' in 2008. These genera are categorized into three subfamilies. The Aspredinidae are often recognized as a part of the primarily Asian superfamily Sisoroidea as the sister group to the family Erethistidae. However, other authors find that they are sister to the superfamily Doradoidea, which includes Doradidae, Auchenipteridae, and perhaps Mochok ...

Bunocephalus
''Bunocephalus'' is a genus of banjo catfishes from South America. It is found in Magdalena, Orinoco, Amazon, Paraguay- Paraná, and São Francisco Rivers. It is also the only aspredinid genus found west of the Andes, found in the Atrato, San Juan, and Patía Rivers. This genus is a part of the family Aspredinidae, known as banjo catfishes for their large, flattened heads and slender tails that give the appearance of a banjo. Most species exhibit cryptic coloration, and the same holds true among ''Bunocephalus'' species. The skin is completely keratinized and is covered by large, unculiferous tubercles. ''Bunocephalus'' species may reach up to 13 centimetres SL. Species There are currently 12 recognized species in this genus: * ''Bunocephalus aleuropsis'' Cope, 1870 * ''Bunocephalus amaurus'' C. H. Eigenmann, 1912 (Camouflaged catfish) * ''Bunocephalus chamaizelus'' C. H. Eigenmann, 1912 * '' Bunocephalus colombianus'' C. H. Eigenmann, 1912 * '' Bunocephalus coracoid ...

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 (shark Sharks are a group of elasmobranch fish chara ...

Paraná River
The Paraná River ( es, Río Paraná, links=no , pt, Rio Paraná, gn, Ysyry Parana) is a river in south-central South America, running through Brazil, Paraguay, and Argentina for some ."Parana River".

Encyclopædia Britannica Inc., 2012. Web. 26 May. 2012 Among South American rivers, it is second in length only to the Amazon River. It merges with the Paraguay River and then farther downstream with the Uruguay River to form the Río de la Plata and empties into the Atlantic Ocean. The first European to go up the Paraná River was the Venetian explorer Sebastian Cabot, in 1526, while working for Spain. A drought hit the river in 2021, causing a 77-year low.
