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 single ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Characidae
Characidae, the characids or characins is a family of freshwater subtropical and tropical fish, belonging to the order Characiformes. The name "characins" is the historical one, but scientists today tend to prefer "characids" to reflect their status as a by and large monophyletic group at family rank. To arrive there, this family has undergone much systematic and taxonomic change. Among those fishes that remain in the Characidae for the time being are the tetras, comprising the very similar genera ''Hemigrammus'' and ''Hyphessobrycon'', as well as a few related forms such as the cave and neon tetras. Fish of this family are important as food and also include popular aquarium fish species. These fish vary in length, though many are less than . One of the smallest species, ''Hyphessobrycon roseus'', grows to a maximum length of 1.9 cm. These fish inhabit a wide range and a variety of habitats. They originate in the Americas, ranging from southwestern Texas and Mexico through ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hepsetidae
''Hepsetus'' is a genus of African fishes, the African pikes or African pike characins, in the order Characiformes. It is the sole genus in the family Hepsetidae. It was long believed that only a single widespread species existed, ''H. odoe'', but studies in 2011–2013 have shown that this species is restricted to parts of West and Central Africa. The well-known species of southern Africa, including Kafue River, is '' Hepsetus cuvieri''. These predatory fish reach up to in length. Species There are currently six recognized species in this genus: * '' Hepsetus cuvieri'' ( Castelnau, 1861) * ''Hepsetus kingsleyae'' Vreven, Decru & Snoeks, 2013 * '' Hepsetus lineatus'' ( Pellegrin, 1926) * '' Hepsetus microlepis'' (Boulenger, 1901) * '' Hepsetus occidentalis'' Decru, Snoeks & Vreven, 2013 * ''Hepsetus odoe'' (Bloch, 1794) Synonym: * ''Hepsetus akawo'' Decru, Vreven & Snoeks, 2012 = ''Hepsetus odoe ''Hepsetus odoe'', the African pike characin, is a predatory freshwater ch ...

Distichodontidae
The Distichodontidae are a family of African freshwater fishes of the order Characiformes. Two evolutionary grades are found in this family; micropredators (predators of very small organisms like aquatic insect larvae) and herbivores have a nonprotractile upper jaw and a deep to shallow body, while carnivores have a movable upper jaw and an elongated body. Although the herbivores primarily feed on plant material, these species often have omnivorous tendencies. The carnivores include specialized fish-eaters (genus ''Mesoborus''), fin-eaters (''Belonophago'', ''Eugnathichthys'' and ''Phago'') and species that will feed on both whole fish and fins (''Ichthyborus''). The fin-eaters attack other fish, even ones that are much larger, where they bite off pierces of fins with their sharp teeth. The fish in Distichodontidae vary greatly in size among species, with the smallest micropredators being less than in length, and the largest herbivores can reach up to . Genera The 17 genera i ...

Anostomidae
The Anostomidae are a family of ray-finned fishes that belong to the order Characiformes. Closely related to the Chilodontidae and formerly included with them, the Anostomidae contain about 150 described species. Commonly known as anostomids, they are found in freshwater habitats from the Río Atrato in northernmost South America to warm-temperate central Argentina; they are of Amazon origin, with few found west of the Andes (mainly in Colombia and Venezuela). Their scientific name approximately means "mouth on top", from Ancient Greek ''áno-'' (ἄνω) "up" (as an adverb) + ''stóma'' (στόμᾶ) "mouth", in reference to the arrangement of these fishes' mouth opening.FishBase (2004), Sidlauskas & Vari (2008) Description Anostomids have elongated bodies ranging from in length; their shape varies between fusiform and deeper-bodied, but even the latter are only moderately laterally. They have elongated, tapering heads with rather long, straight snouts, and small apical to up ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iguanodectidae
Iguanodectidae is a family of freshwater fish in the order Characiformes that lives in South America. It is home to the subfamily Iguanodectinae (Eigenmann, 1909) and the monotypic ''Bryconops'' clade. Several species in the family, such as the green line lizard tetra (''Iguanodectes spilurus''), the tailspot tetra (''Bryconops caudomaculatus''), and the orangefin tetra (''Bryconops affinis''), are sometimes taken as aquarium fish. Description Iguanodectids are generally small, and are brightly colored or reflective, making them moderately-popular ornamental fish. They range from 3.1 cm to 15 cm SL (standard length). They are rather narrow in shape, somewhat resembling minnows; ichthyologist Carl H. Eigenmann compared them to smelt. Habitat Iguanodectids are found in South America, spread all across the northern half of the continent. Though they primarily inhabit freshwater, Iguanodectid fishes are known to tolerate brackish water as well. Habitat destruction, ...

Crenuchidae
The Crenuchidae, South American darters, are a family of freshwater fish of the order Characiformes. The 12 genera include about 74 species, though several species are undescribed. These fish are relatively small (usually under in standard length) and originate from eastern Panama and South America. Both subfamilies were previously included in the family Characidae, and were placed in a separate family by Buckup, 1998. Buckup, 1993, revised all genera, except ''Characidium''.Buckup, P.A. 1993.

Chalceidae
Chalceidae, the tucanfishes, is a family of freshwater fish first described by Henry Weed Fowler in the year 1958. It is a monotypic family, home only to the genus ''incertae sedis'' ''Chalceus''. All members of the family inhabit areas of northern South America, including the Amazon River and various tributaries. Classification Chalceidae is in the order Characiformes. The genus ''Chalceus'' used to be placed in the family Characidae, and is still listed there by several sources (like GBIF and ITIS). Research since its original placement suggested movement into the family Chalceidae, based upon phylogenetic significance as a monophyletic group.Oliveira, C., Avelino, G.S., Abe, K.T., Mariguela, T.C., Benine, R.C., Orti, G., Vari, R.P., & Correa e Castro, R.M.

Chilodontidae (fishes)
The Chilodontidae, or headstanders, are a small family of freshwater characiform fishes found in northern and central South America. This family is closely related to the family Anostomidae and is sometimes treated as a subfamily, Chilodontinae, within Anostomidae. Due to issues of homonymy with two other family-rank names called "Chilodontidae", it has been proposed that the fish family retain the spelling, and the other families will be either suppressed or renamed. Chilodontids have colourful markings, making them popular in aquariums. They are small fish, all less than in adult length, and are distinguished by their habitual head-down postures. Genera This family currently contains two genera: * Genus ''Caenotropus'' (4 species) * Genus ''Chilodus ''Chilodus'' is a genus of chilodontid headstanders from South America, found in the Orinoco and Amazon Basins, as well as various rivers in the Guianas.

Curimatidae
The Curimatidae, toothless characins, are a family of freshwater fishes, of the order Characiformes. They originate from southern Costa Rica to northern Argentina. The family has around 105 species, many of them frequently exploited for human consumption. They are closely related to the Prochilodontidae. This family lacks jaw teeth, although they do sometimes have small teeth on their pharyngeal plates. They eat films of slime coating underwater surfaces, which consist largely of algae, zooplankton and detritus. It has been suggested that feeding behavior of some species like ''Psectrogaster essequibensis'' may change its diet pattern in function of the sediment content of the water, showing a regime mainly based on algae in waters with high sediment load, until an omnivorous or detritivore regime in waters with low sediment load. Classification The family has eight genera and around 105 species: Family Curimatidae * '' Curimata'' (13 species) * ''Curimatella'' (five species) ...
