Loricarioidei
Loricarioidei is a suborder of catfishes (order Siluriformes). It contains the six families Trichomycteridae, Nematogenyiidae, Callichthyidae, Scoloplacidae, Astroblepidae, and Loricariidae. Some schemes also include Amphiliidae. This superfamily, including Amphiliidae, includes about 156 genera and 1,187 species. Taxonomy Loricarioidea was previously considered a part of Siluroidei, a clade of all catfishes excluding Diplomystidae. In Nelson, 2006, this grouping is sister to the superfamily Sisoroidea. However, in a recent molecular analysis, it was determined that the suborder Loricarioidei (not including Amphiliidae) is sister to a group including Diplomystidae and Siluroidei. Amphiliidae, in this analysis, was found to be much more closely related to Mochokidae or Malapteruridae. It is disputed whether Loricarioidea or Diplomystidae are the most basal group of catfish, with molecular studies favoring the former while morphological studies favor the latter. The earliest ...

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] |
Afrocascudo
''Afrocascudo'' is a controversial genus of extinct Neopterygii, neopterygian fish, either an ancient loricariid catfish or a juvenile Obaichthyidae, obaichthyid Lepisosteiformes, lepisosteiform of the genus ''Obaichthys''. It is known from the Late Cretaceous Douira Formation (Kem Kem Group) of Morocco. The genus contains a Monotypic taxon, single species, ''A. saharaensis'', known from a partial articulated specimen. Discovery and naming The ''Afrocascudo'' holotype specimen, Museum of Natural History of Marrakech, MHNM-KK-OT 36 a—c, was discovered in sediments of the Douira Formation (Jbel Oum Tkout locality) of the Kem Kem Group near Tafraoute Sidi Ali in Errachidia Province, southeastern Morocco. The Joint, articulated specimen consists of a nearly complete fish collected in three pieces. It is missing parts of the head and fins. In 2024, Brito et al. Species description, described ''Afrocascudo saharaensis'' as a new genus and species of loricariid catfishes based on th ...
