Acestrorhynchidae
Acestrorhynchidae is a family of freshwater fish in the order Characiformes, found in South America. Members of this family are known as freshwater barracudas (not to be confused with the unrelated true barracudas of the Sphyraenidae) and biting tetras. Until recently, this family contained only the genus '' Acestrorhynchus''. However, taxonomic studies have found that the subfamilies Heterocharacinae (originally placed in the closely related Characidae) and Roestinae (originally placed in the more distantly related Cynodontidae) are actually more closely related to ''Acestrorhynchus'', and now they are also placed in this family. The family is classified as follows: * Family Acestrorhynchidae ** Subfamily Acestrorhynchinae Eigenmann, 1912 (freshwater barracudas) *** Genus '' Acestrorhynchus'' Eigenmann & Kennedy, 1903 ** Subfamily Roestinae Lucena & Menezes, 1998 (biting tetras) *** Genus '' Gilbertolus'' Eigenmann, 1907 *** Genus '' Roestes'' Günther, 1864 ** Subfamily ...

Characiformes
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 sin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Acestrorhynchus
''Acestrorhynchus'' ("needle jaw" ) is a genus of characiform fish found only in fresh water in South America, the sole genus in the subfamily Acestrorhynchinae. Their greatest diversity is in the Orinoco and Amazon basins. These fish have elongated pike-like bodies and large conical teeth, adapted for predation on other types of fish. They are sometimes referred to as freshwater barracudas in the aquarium trade, although the name is used of other characins, as well. They range from in length. Until recently, they were considered the only genus in the family Acestrorhynchidae, but phylogenetic studies have recovered several smaller characins previously placed elsewhere in the family (known as " biting tetras") as closely related to them. Common names are ''cachorinho, cachorro, mopiye, payala, pejezorro, pez cachorro, pez zorro'', pike characin, ''moinge, halatawéi, halataway, dagu fisi, ueua, wayabra, zadoe,'' freshwater barracuda, ''saicanga, branca, cajaba, cachorra magra, c ...

Cynodontidae
Cynodontidae, from Ancient Greek κύων (''kúōn''), meaning "dog", and ὀδούς (''odoús''), meaning "tooth", also known as dogtooth characins or vampire tetras, are a family of predatory, characiform freshwater fishes from South America. This group is not very diverse, and includes only three genera and 8 species. The largest species in this family ranges up to . They are characterized by an oblique mouth and very long distinct canines, which are used to capture and stab their prey, other fish that can be up to half the length of the cynodontine itself. They are not prized as food fish, but are important in subsistence and commercial fisheries. '' Hydrolycus'' are game fish, having been recently added to the International Game Fish Association in the fly and rod class. Cynodontid fish are also sometimes housed in aquaria.

Characidae
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 Americ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
