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 Mochokidae. ...

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] |
Bunocephalus Verrucosus
''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 coracoideus' ...

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.

Pterobunocephalus
''Pterobunocephalus'' is a genus of banjo catfishes found in tropical South America. Distribution The genus is widespread in the Orinoco, Amazon and Paraguay-Paraná River systems and typically occur at depths greater than 5 metres. Description ''Pterobunocephalus'' is genus of small to medium-sized aspredinid species. Members of this genus are distinguished from all other aspredinids by the following characters having an extremely depressed (flattened) head and body, having the head ornamentation highly reduced or absent, often having a distinct notch in the upper jaw, and having 10–20 anal fin rays. Females of this genus carry embryo An embryo is an initial stage of development of a multicellular organism.

Ernstichthys
''Ernstichthys'' is a genus of banjo catfishes that occurs in the Amazon and Orinoco basins.

''Ernstichthys'' species are small to medium-sized, armored aspredinids. Members of this genus are distinguished from all other aspredinids by having two sets of paired pre- anal-fin plates and a strongly recurved pectoral Pectoral may refer to: * The chest region and anything relating to it. * Pectoral cross, a cross worn on the chest * a decorative, usually jeweled version of a gorget * Pectoral (Ancient Egypt), a type of jewelry worn in ancient Egypt * Pectoralis ... spine that is much longer than first branched pectoral-fin ray.

Hoplomyzon
''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''. Members of this genus are distinguished from all other aspredinids by having each premaxilla with two bony knobs superficially covered by fleshy papillae, the dorsal and ventral armor plates not overlapping, and 2–3 sets of paired pre- anal-fin plates. They also have the maxillary barbels adnate with the head and the pectoral spine less than one-quarter of the fish's standard length.

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 premaxillae, a row of fleshy papillae projecting anteriorly off the lower lip, flattened unculi and unculiferous tubercle In anatomy, a tubercle (literally 'small tuber', Latin for 'lump') is any round nodule, small eminence, or warty outgrowth found on external or internal organs of a plant or an animal.

Aspredinichthys
''Aspredinichthys'' is a genus of banjo catfishes found in fresh and brackish waters in tropical South America from the Orinoco delta, through the Guianas, to the Amazon delta. Both species are found in lower portions of rivers and in coastal waters of northern South America from Venezuela to northern Brazil where they are benthic fish. Description ''Aspredinichthys'' species are large aspredinids that grow up to about 22.0 centimetres (8.7 in) SL; they are distinguished from all other aspredinids by the characters including having 8 pectoral-fin rays and several pairs of accessory mental barbels present. The two species placed in this genus are very similar in appearance and are most readily separated by the pattern and number of accessory mental barbels. Species There are currently two described species in this genus: * '' Aspredinichthys filamentosus'' (Valenciennes, 1840) (Sevenbarbed banjo) * '' Aspredinichthys tibicen'' (Valenciennes Valenciennes (, also ...
