Aspredinidae
The Aspredinidae are a small South American family (biology), family of catfishes (order (biology), 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 River, Magdalena, Orinoco, Amazon River, Amazon, São Francisco River, São Francisco, Paraguay River, Paraguay-Paraná River, Paraná, and Uruguay River, Uruguay). ''Bunocephalus'' is the only genus found in rivers west of the Andes including the Atrato River, Atrato, San Juan River (Colombia), San Juan, and Patía Rivers. Taxonomy Of the 13 genus, 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 cladistics, ...

Catfish
Catfish (or catfishes; order (biology), order Siluriformes or Nematognathi) are a diverse group of ray-finned fish. Catfish are common name, named for their prominent barbel (anatomy), barbels, which resemble a cat's whiskers, though not all catfish have prominent barbels or "whiskers", with some seemingly not having them. Siluriformes as a whole are Fish scale, scale-less, with neither the Armoured catfish, armour-plated nor the naked species having scales. This order of fish are Autapomorphy, defined by features of the skull and swimbladder. Catfish range in size and behavior from the three List of largest fish, largest species alive, the Mekong giant catfish from Southeast Asia, the wels catfish of Eurasia, and the piraíba of South America, to detritivorous and scavenging bottom feeders, down to tiny ectoparasitic species known as the Candiru (fish), candirus. In the Southern United States, catfish species may be known by a variety of slang names, such as "mud cat", " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 cor ...

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.

Platystacus Cotylephorus
''Platystacus '' is a genus of banjo catfish in the family Aspredinidae. It is monotypic, being represented by the single species ''Platystacus cotylephorus'', commonly known as the banded banjo . The genus ''Platystacus'' is the sister group to a clade containing '' Aspredo'' and '' Aspredinichthys''. ''P. cotylephorus'' originates from coastal waters and lower portions of rivers of northern South America, from Venezuela to northern Brazil. This species grows up to about SL and is distinguished from all other aspredinids by having 4+5 caudal fin rays. They are further distinguished from its close relatives by the absence of accessory maxillary barbels and the presence of well developed rows of unculiferous tubercles. ''P. cotylephorus'' is usually found in brackish waters on the soft bottoms of shallow, turbid water near to the mouths of rivers. reportedly it migrates into freshwater, though spawning Spawn is the Egg cell, eggs and Spermatozoa, sperm released or deposit ...

''Hoplomyzon'' is a genus of banjo catfishes that are native to tropical South America. ''Hoplomyzon'' species are small, armoured aspredinids, growing up to 32 millimetres (1.3 in) SL in ''H. sexpapilostoma''.

Xyliphius
''Xyliphius'' is a genus of banjo catfishes from South America. This genus appears to be widespread in the Magdalena, Orinoco, Amazon, and Paraguay-Paraná River systems where they are most common in deeper waters. ''Xyliphius'' includes moderately sized aspredinids, ranging from 8.8–14.7 centimetres (3.5–5.8 in) SL. Species of this genus are distinguished from all other aspredinids by having highly reduced eyes, toothless premaxilla The premaxilla (or praemaxilla) is one of a pair of small cranial bones at the very tip of the upper jaw of many animals, usually, but not always, bearing teeth. In humans, they are fused with the maxilla.
