Cetopsidium
''Cetopsidium'' is a genus of catfishes (order Siluriformes) of the family Cetopsidae. Taxonomy ''Cetopsidium'' was described in 2005, its name coming from the ''Cetopsis'', the first described cetopsid genus, and ''idium'' which means diminutive, in reference to the relatively small size of ''Cetopsidium'' species. Three existing species were transferred to this genus and three new species were described. In 2009 a new species, ''Cetopsidium soniae'', was described bringing the number of species in the genus to seven. Species There are currently seven recognized species in this genus: * '' Cetopsidium ferreirai'' Vari, Ferraris & de Pinna, 2005 * '' Cetopsidium minutum'' ( C. H. Eigenmann, 1912) * '' Cetopsidium morenoi'' ( Fernández-Yépez, 1972) * '' Cetopsidium orientale'' (Vari, Ferraris & Keith, 2003) * '' Cetopsidium pemon'' Vari, Ferraris & de Pinna, 2005 * '' Cetopsidium roae'' Vari, Ferraris & de Pinna, 2005 * '' Cetopsidium soniae'' Vari & Ferraris, 2009 Distribu ...

Cetopsidae
The Cetopsidae are a small family of catfishes (order Siluriformes), commonly called the whale catfishes. Taxonomy This family contains five genera divided into two subfamilies, Cetopsinae and Helogeneinae. Helogeneinae was previously a family-level group, but now it has been reclassified as a subfamily of Cetopsidae. This subfamily contains four species in the genus ''Helogenes''. The subfamily Cetopsinae contains four genera. ''Cetopsidium'' contains six species, ''Cetopsis'' contains 21 species, ''Denticetopsis'' contains seven species, and ''Paracetopsis'' contains three species; this makes a total of 37 cetopsines. The genera have been changed as recently as 2005 with the genera ''Bathycetopsis'', ''Hemicetopsis'', and ''Pseudocetopsis'' set in synonymy with ''Cetopsis'' and the description of the new genus ''Cetopsidium''. ''Cetopsidium'' is the sister group to the rest of Cetopsinae. ''Denticetopsis'' forms the next sister group to the remaining cetopsine genera. The tribe ...

Denticetopsis
''Denticetopsis'' is a genus of catfishes (order Siluriformes) of the family Cetopsidae. Taxonomy Originally ''Denticetopsis'' as described by Ferraris in 1996 was restricted to two species, ''D. royeroi'' and ''D. sauli''. These two species have proved to be a subunit of a larger clade that also includes two species previously assigned to the now invalid genus ''Pseudocetopsis'' (''D. macilenta'', ''D. praecox''), together with three species described as new in 2005 (''D. epa'', ''D. iwokrama'', ''D. seducta''). Species There are currently seven recognized species in this genus: * '' Denticetopsis epa'' Vari, Ferraris & de Pinna, 2005 * '' Denticetopsis iwokrama'' Vari, Ferraris & de Pinna, 2005 * '' Denticetopsis macilenta'' ( C.

Barbel (anatomy)
In fish anatomy and turtle anatomy, a barbel is a slender, whiskerlike sensory organ near the mouth. Fish that have barbels include the catfish, the carp, the goatfish, the hagfish, the sturgeon, the zebrafish, the black dragonfish and some species of shark such as the sawshark. Barbels house the taste buds of such fish and are used to search for food in murky water. The word "barbel" comes from the Middle Latin ''barbula'', for "little beard." Barbels are sometimes erroneously referred to as '' barbs'', which are found in bird feathers for flight. Barbels may be located in a variety of locations on the head of a fish. "Maxillary barbels" refers to barbels on either side of the mouth. Barbels may also be nasal, extending from the nostrils. Also, barbels are often mandibular or mental, being located on the chin. In fish, barbels can take the form of small, fleshy protrusions or long, cylindrical shaped extensions of the head of a fish. The cylindrical barbel shapes are bui ...

Dorsal Fin
A dorsal fin is a fin located on the back of most marine and freshwater vertebrates within various taxa of the animal kingdom. Many species of animals possessing dorsal fins are not particularly closely related to each other, though through convergent evolution they have independently evolved external superficial fish-like body plans adapted to their marine environments, including most numerously fish, but also mammals such as cetaceans (whales, dolphins, and porpoises), and even extinct ancient marine reptiles such as various known species of ichthyosaurs. Most species have only one dorsal fin, but some have two or three. Wildlife biologists often use the distinctive nicks and wear patterns which develop on the dorsal fins of large cetaceans to identify individuals in the field. The bony or cartilaginous bones that support the base of the dorsal fin in fish are called ''pterygiophores''. Functions The main purpose of the dorsal fin is to stabilize the animal against rollin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
