Characins
Characidae, the characids, is a family of freshwater subtropical and tropical fish belonging to the order Characiformes. They are found throughout much of Central and South America, including such major waterways as the Amazon and Orinoco Rivers.Nelson (2006) These fish vary in length; many are less than . The name " characins" is a historical one, but scientists today tend to prefer "characids" to reflect their status as a, by and large, monophyletic group (at family rank). This family includes some of the first characiforms to be described to science, such as '' Charax'' and ''Tetragonopterus'', and thus lend their name to the order, as well as to common names such as "characin" and "tetra". Past taxonomic treatments had a much more expansive definition of the family, including numerous South American fish families such as the piranhas and dorados, as well as the African alestids. Following multiple taxonomic revisions, this was eventually restricted to just the American "tet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Characin
Characiformes is an order of ray-finned fish, comprising the characins and their allies. Grouped in 18 recognized families, more than 2000 different species are described, including the well-known piranha and tetras.; Buckup P.A.: "Relationships of the Characidiinae and phylogeny of characiform fishes (Teleostei: Ostariophysi)", ''Phylogeny and Classification of Neotropical Fishes'', L.R. Malabarba, R.E. Reis, R.P. Vari, Z.M. Lucena, eds. (Porto Alegre: Edipucr) 1998:123-144. Taxonomy The Characiformes form part of a series called the Otophysi within the superorder Ostariophysi. The Otophysi contain three other orders, Cypriniformes, Siluriformes, and Gymnotiformes. The Characiformes form a group known as the Characiphysi with the Siluriformes and Gymnotiformes. The order Characiformes is the sister group to the orders Siluriformes and Gymnotiformes, though this has been debated in light of recent molecular evidence. Originally, the characins were all grouped within a sing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stevardiidae
Stevardiidae is a large family of freshwater fish in the order Characiformes. It includes many genera previously placed in the family Characidae, which was split into multiple families in 2024. They are found throughout South and Central America. In earlier taxonomic treatments, most genera in this family were placed in the characid subfamily Glandulocaudinae, which has been redefined as a much smaller subfamily of the Stevardiidae. As suggested by their former taxonomic name, a gland on their caudal fin is found almost exclusively in the males of many species of this family, which allows the release and pumping of pheromones. Members of this subfamily have complex courtship behaviors which lead to insemination. The ecology and life history of these fish is complex yet little studied. Stevardiids are important components of the diet for commercially-harvested larger fish. Taxonomy The following taxonomy is based on '' Eschmeyer's Catalog of Fishes'': Family Stevardiidae * S ...

Acestrorhamphidae
Acestrorhamphidae, the American tetras, are a diverse family of freshwater fish in the order Characiformes. They are native to North and South America, from the southwestern United States south to temperate Argentina, with a few species introduced to other parts of the world. It includes many genera previously placed in the family Characidae, which was split into multiple families in 2024. It contains many of the most famous ornamental aquarium fish that are popularly known as tetras.

Eschmeyer's Catalog Of Fishes
Catalog of Fishes is a comprehensive on-line database and reference work on the scientific names of fish species and genera. It is global in its scope and is hosted by the California Academy of Sciences. It has been compiled and is continuously updated by the curator emeritus of the CAS fish collection, William N. Eschmeyer. The taxonomy maintained by the Catalog of Fishes is considered authoritative and it is used as a baseline reference for instance by the broader global fish database FishBase, which involves cross-references to the Catalog's information for all accepted taxa. the searchable catalogue contains entries for about 58,300 fish species names, about 33,400 of which are currently accepted (valid), and for some 10,600 genera (5,100 valid).

Aphyocharax Anisitsi
The bloodfin tetra (''Aphyocharax anisitsi'') is a species of characin from the Paraná River basin in South America. The bloodfin is a relatively large tetra, growing to 5.5 cm.Nico, L., 2022, Aphyocharax anisitsi' Eigenmann and Kennedy, 1903: U.S. Geological Survey, Nonindigenous Aquatic Species Database, Gainesville, FL, Revision Date: 6/22/2012, Peer Review Date: 6/22/2012, Access Date: 9/4/2022 Its notable feature (as the name suggests) is the blood-red colouration of the tail, dorsal, anal and adipose fin, while the body is silver in color. Bloodfin tetras are extremely hardy, making them popular with novice fish keepers. Aquarium care Bloodfin tetras are typically kept in schools of five or more. They swim mainly in the upper and middle water layers and are highly sociable fishes, mixing well with other types of tetras and tropical fish in general, so are often kept (like many other tetras) in a community tank. However, they will tend to nip at the fins of fish wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alestidae
African tetras (family (biology), family Alestidae, formerly spelled Alestiidae) are a group of Characiformes, characiform fish found exclusively in Africa. This family contains about 18 genera and 119 species. Among the best known members are the Congo tetra, and Hydrocynus, African tigerfish. Although presently found only in Africa, fossil evidence suggests that during the Paleogene, they ranged as far north as southern Europe and as far east as the Arabian subcontinent. Fossil remains date back to potentially the Late Paleocene with ''Hydrocynus'' remains known from Algeria. Alestid-like teeth are also known from the Late Cretaceous (Maastrichtian) of France, and phylogenetic evidence also suggests they diverged around this time.

Piranha
A piranha (, or ; ) is any of a number of freshwater fish species in the subfamily Serrasalminae, of the family Serrasalmidae, in the order Characiformes. These fish inhabit South American rivers, floodplains, lakes and reservoirs. Although often described as extremely predatory and mainly feeding on fish, their dietary habits vary extensively, and they will also take plant material, leading to their classification as omnivorous. Etymology The name originates from Old Tupi '' pirãîa'', being first attested in the 1587 treatise ' by Portuguese explorer Gabriel Soares de Sousa. ''Piranha'' first appears in 1869 in English literature, likely borrowed from Portuguese. Taxonomy and evolution Piranhas belong to the family Serrasalmidae, which includes closely related omnivorous fish such as pacus. Traditionally, only the four genera '' Pristobrycon'', '' Pygocentrus'', '' Pygopristis'', and '' Serrasalmus'' are considered to be true piranhas, due to their specialized teeth. H ...
