Proteocephalidae
Proteocephalidae is a diverse family tapeworms with nearly 300 recognized species in 66 genera and 13 subfamilies, whose species are found in every continent. They are mainly parasites of siluriforms and other freshwater fishes, but also parasitize reptiles and amphibians. A typical proteocephalid life cycles include planktonic crustaceans, and small fish as intermediate hosts.

Brown Bullhead
The brown bullhead (''Ameiurus nebulosus'') is a fish of the family Ictaluridae that is widely distributed in North America. It is a species of bullhead catfish and is similar to the black bullhead (''Ameiurus melas'') and yellow bullhead (''Ameiurus natalis''). It was originally described as ''Pimelodus nebulosus'' by Charles Alexandre Lesueur in 1819, and is also referred to as ''Ictalurus nebulosus''. The brown bullhead is also widely known as the "mud pout", "horned pout", "hornpout", or simply "mud cat", a name also used with the other bullhead species. The brown bullhead is important as a clan symbol of the Ojibwe people. In their tradition, the bullhead or is one of six beings that came out of the sea to form the original clans.

Tachysurus Fulvidraco
''Tachysurus fulvidraco'', the yellowhead catfish or Korean bullhead, is a species of bagrid catfish found in eastern Asia from Siberia to China, Korea, Vietnam, and Laos, where it can be found in lakes and river channels. It can reach a maximum length of 34.5 cm (13.5 in), weighing 3 kg (6.6 lb), though it is much more commonly found to a length of 8 cm. It is a minor component of commercial fisheries. Parasites A total of 11 species of helminthes, including six species of digeneans, three species of nematodes, a species of cestode, and an acanthocephalan have been found in the stomach and intestines of ''T. fulvidraco'':.Li W.

Silurus Biwaensis
''Silurus biwaensis'', the giant Lake Biwa catfish or ''Biwako-o'namazu'' (ビワコオオナマズ (Japan)), is a large predatory catfish species endemic to Lake Biwa in Japan. Description The giant Lake Biwa catfish is very similar to wels catfish, which it is closely related to. It has an elongated cylindrical body and can reach up to in length and weigh as much as . The top of the body is dark grey to black in colour while the underside is a pale, whitish colour. Lifecycle They prey on fish and frogs which live in the lake. ''S. biwaensis'' is the largest predatory fish in Lake Biwa. Using telemetry methods researchers tried to explain the migratory behavior of the species. It was found that the fish are more or less site-faithful and mostly stay close to their spawning grounds. Other studies have shown that the sub-populations of the lake hardly mix. Relationship to humans Some fishermen believe that the catfish change their behavior and become very active when an earthqua ...

Redtail Catfish
The redtail catfish, ''Phractocephalus hemioliopterus'', is a pimelodid (long-whiskered) catfish. In Venezuela, it is known as cajaro, and in Brazil, it is known as pirarara, stemming from the Tupi language words ''pirá'' and ''arara''. It is the only extant species of the genus ''Phractocephalus''. This fish is common in the aquarium trade, although its massive adult size makes it unsuitable for all but the largest aquariums. They feed on fish, crustaceans and fallen fruits. They are not evaluated by IUCN. Fossil species Although the redtail catfish is the only living representative of this genus, there are other members that date back to the upper Miocene, and are only known from fossil remains. '' P. nassi'' was described in 2003, from the Urumaco Formation at Urumaco, Venezuela. Another fossil species, '' P. acreornatus,'' is known from the Solimões Formation, Acre, Brazil. This genus has a minimum age of about 13.5 million years. Description ''Phractocephalus hemi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Auchenipterus
''Auchenipterus'' is a genus of driftwood catfishes (order Siluriformes). Taxonomy The genus is hypothesized to be monophyletic, diagnosed by the shared presence of grooves in the ventral surface of the head that accommodate adducted mental barbels. The presence of papillae on the dorsal and medial surface of the ossified maxillary barbel of mature males is also a possible synapomorphy, but in three species this cannot be confirmed as there are no adult male specimens yet discovered. This genus contains 11 species: *'' Auchenipterus ambyiacus'' Fowler, 1915 *'' Auchenipterus brachyurus'' (Cope, 1878) *'' Auchenipterus brevior'' C. H. Eigenmann, 1912 *'' Auchenipterus britskii'' Ferraris & Vari, 1999 *'' Auchenipterus demerarae'' C. H. Eigenmann, 1912 *'' Auchenipterus dentatus'' Valenciennes, 1840 *'' Auchenipterus fordicei'' C.

Brachyplatystoma
''Brachyplatystoma'' is a genus of catfish from the family Pimelodidae. As the occasionally used common name goliath catfishes indicates, this genus includes some of the largest species of catfish, including the piraíba, ''B. filamentosum'', which reaches up to the region of in length. ''Brachyplatystoma'' are found in the Amazon and Orinoco basins, and other tropical freshwater and brackish habitats in South America. Some species are migratory. These fish are important as food fish and, to some extent, aquarium fish. Taxonomy ''Brachyplatystoma'' originates from Greek ''brachys'', ''platys'', and ''stoma'', which mean ''short'', ''flat'', and ''mouth'' respectively. This genus was described in 1862 by Pieter Bleeker. The type species is ''B. vaillantii''. The subgenus ''Malacobagrus'' is applied to ''B. capapretum'', ''B. filamentosum'', ''B. rousseauxii'', and the extinct species ''B. promagdalena'', which only is known from fossil remains.
