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] [Amazon] |

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 ...

Tetragonopterus
''Tetragonopterus'' is a genus of fish in the family Characidae native to South America. It is the only member of the subfamily Tetragonopterinae. The subfamily was originally much larger as previously defined, and contained many of the genera known as " tetras". The name "tetra" derives from this former classification. Species There are currently 14 recognized species of this genus: * '' Tetragonopterus anostomus'' G. S. C. Silva & Benine, 2011 Silva, G.S.C. & Benine, R.C.

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] [Amazon] |
Tetra
Tetra is the common name of many small freshwater characiform fishes. Tetras come from Africa, Central America, and South America, belonging to the biological families Characidae, Alestidae (the "African tetras"), Lepidarchidae, Lebiasinidae, Acestrorhynchidae, Stevardiidae, and Acestrorhamphidae. In the past, all of these families were placed in the Characidae. The Characidae and their allies are distinguished from other fish by the presence of a small adipose fin between the dorsal and caudal fins. Many of these, such as the neon tetra (''Paracheirodon innesi''), are brightly colored and easy to keep in captivity. Consequently, they are extremely popular for home aquaria. ''Tetra'' is no longer a taxonomic, phylogenetic term. It is short for ''Tetragonopterus'', a genus name formerly applied to many of these fish, which is Greek for "square-finned" (literally, four-sided-wing). Because of the popularity of tetras in the fishkeeping hobby, many unrelated fish are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
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.

Fish
A fish (: fish or fishes) is an aquatic animal, aquatic, Anamniotes, anamniotic, gill-bearing vertebrate animal with swimming fish fin, fins and craniate, a hard skull, but lacking limb (anatomy), limbs with digit (anatomy), digits. Fish can be grouped into the more basal (phylogenetics), basal jawless fish and the more common jawed fish, the latter including all extant taxon, living cartilaginous fish, cartilaginous and bony fish, as well as the extinct placoderms and acanthodians. In a break to the long tradition of grouping all fish into a single Class (biology), class (Pisces), modern phylogenetics views fish as a paraphyletic group. Most fish are ectotherm, cold-blooded, their body temperature varying with the surrounding water, though some large nekton, active swimmers like white shark and tuna can hold a higher core temperature. Many fish can communication in aquatic animals#Acoustic, communicate acoustically with each other, such as during courtship displays. The stud ...

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 ...
