Claroteidae
The Claroteidae are a family of catfish (order Siluriformes) found in Africa. This family was separated from Bagridae. However, the monophyly of the family is sometimes contested. The 9 genera contain 65 known species of claroteids. The family Auchenoglanididae was formerly considered a subfamily of this family. This group was also often formerly placed in Bagridae. A well-known species is the African big-eye catfish, '' Chrysichthys longipinnis''. Claroteids have moderately elongated bodies, usually with four pairs of barbels, an adipose fin, and strong pectoral and dorsal fin spines. The earliest known fossil member of the Claroteidae is '' Nigerium'' from the Late Paleocene and Early Eocene of Nigeria and Mali. The extinct genus '' Eaglesomia'' is also known from the Middle Eocene of Nigeria. The Late Eocene genus '' Fajumia'' from Egypt is of uncertain affinities, but most likely belongs to this group. In addition, extinct species of the extant genus '' Chrysichthys'' are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eaglesomia
''Eaglesomia'' is an extinction, extinct genus of freshwater catfish, most likely of the family (biology), family Claroteidae, that inhabited western Africa during the Eocene. It contains a single species, ''E. eaglesomei'', known from the presumably Lutetian-aged marine Oshosun Formation, Oshosun and Ameki Formation, Ameki Formations of Nigeria. Initially placed in the modern genus ''Chrysichthys'', a 1934 reanalysis found it to be more similar to the Egyptian fossil catfish ''Socnopaea'', and it was thus reclassified into its own genus within the Claroteidae. However, a 2010 study found it to lack several characteristics of the Claroteidae, and thus not be a claroteid. In contrast, a 2021 study retained it in the Claroteidae based on its distinctive skull ornamentation, which more closely resembled that of claroteids than any other catfish family.

Catfish Families
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] |

Nigerium
''Nigerium'' is an extinct genus of catfish known from the early Paleogene of northern Africa. It is the earliest known member of the family Claroteidae, which is still widespread in freshwater habitats of tropical Africa. Its presence also supports the Claroteidae being the earliest occurring catfishes in Africa. It contains two known species: * †''N. wurnoense'' White, 1934 (type species) - Late Paleocene of Sokoto, Nigeria ( Dange Formation) * †''N. tamaguelense'' Longbottom, 2010 - Early Eocene of Mali ( Tamaguélelt Formation of the Trans-Saharan Seaway) In addition, a former third species "''N.''" ''gadense'' White, 1934 is known from the same Late Paleocene deposits as ''N. wurnoense''. However, White only tentatively assigned this species to ''Nigerium'', and an analysis by Murray & Holmes (2021) supported it belonging to a different genus than the other two species. Remains of ''Nigerium'' are found only in marine deposits, despite this family only occurring in fres ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bagridae
The Bagridae are a family of catfish that are native to Africa ('' Bagrus'') and Asia (all other genera) from Japan to Borneo. It includes about 245 species. These fish are commonly known as naked catfishes or bagrid catfishes. Many large bagrids are important as a source of food. Some species are also kept as aquarium fishes. Physical characteristics The dorsal fin is preceded by a spine. The adipose fin is present and can have a relatively long base in some species. The pectoral fin spine can be serrated. The body is completely naked (they have no scales). The maximum length is about . Fishes of the family Bagridae have four pairs of well-developed barbels covered by a layer of taste bud-enriched epithelium Epithelium or epithelial tissue is a thin, continuous, protective layer of cells with little extracellular matrix. An example is the epidermis, the outermost layer of the skin. Epithelial ( mesothelial) tissues line the outer surfaces of man .... Taxonomy The taxon ...
