Characiform
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]   |

Serrasalmidae
The Serrasalmidae (serrasalmids) are a family of characiform fishes, recently elevated to family status. It includes more than 90 species. The name means "serrated salmon family", which refers to the serrated keel running along the belly of these fish. Fish classified as Serrasalmidae are also known by these common names: pacu, piranha, and silver dollar. These common names generally designate differing dental characteristics and feeding habits. Description Serrasalmids are medium- to large-sized characiform fishes that reach about long, generally characterized by a deep, laterally compressed body with a series of midventral abdominal spines or scutes, and a long dorsal fin (over 16 rays). Most species also possess an anteriorly directed spine just before the dorsal fin extending from a supraneural bone; exceptions include members of the genera ''Colossoma'', ''Piaractus'', and ''Mylossoma''. Most serrasalmids have about 60 chromosomes, ranging from 54 to 62.''Metynnis'' has ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Tarumaniidae
''Tarumania'' is a genus of freshwater fish first described in 2017. It contains a single species, ''Tarumania walkerae'', and constitutes the only genus in the family Tarumaniidae. ''T. walkerae'' is a predatory species that hunts among the leaf litter of the flooded forest floor in the Rio Negro drainage basin. Discovery and taxonomy The species first came to the attention of scientists in 2002 in the form of a poorly preserved juvenile specimen collected as part of a survey. The specimen possessed many unusual traits and could not be identified even to family level. Due to the poor preservation, no formal description was attempted until many years later, after the discovery of a living population and collection of better specimens. The genus name ''Tarumania'' was chosen after the site of first collection (the Tarumã Mirim River). ''Tarumania'' is a characiform, the order which includes piranhas and tetras. Due to its distinctness from all other characiformes, the describe ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Hyphessobrycon Bentosi
''Hyphessobrycon bentosi'', the Bentos tetra,ornate tetra, is a species of characin fish found in sluggish tributaries at the Amazon Basin in Brazil and Peru. Occasionally, it makes its way into the aquarium trade. It has often been confused with the rosy tetra. Named in memory of a Colonel Bentos, who was a volunteer on the Thayer Expedition to Brazil (1865-1866), during which the type specimen was collected. Description The ornate tetra can grow up to 4 cm (1.6"). It is silvery pink, and has a dark spot around the gills, which distinguishes it from the rosy tetra. Its dorsal fin is black and has a white tip on it. Males have longer dorsal and anal fins and appear slightly larger than females. Distribution and habitat The ornate tetra lives in sluggish tributaries of the Amazon River, associated flood plain lakes. It is a benthopelagic fish and is often found in creeks and around submerged vegetation. Diet It is an omnivorous fish that feeds on small invertebrates. In ...

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.

Cynodontidae
Cynodontidae, 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 five genera and 14 species. Most of what is known about this family is from the members of the subfamily Cynodontinae, which includes the largest species of this family, up to . The members of subfamily Roestinae only reach up to . and are less known. Physical characteristics Cynodontidae are elongated in shape with a silvery or grey colour and an upturned mouth. Some species have a hunchbacked appearance. The family names (both scientific and common) derive from the long and well-developed canines which are used to spear their prey, mainly other fish. Their pectoral fins are also expanded. The maximum length reached is . Distribution and habitat These fish live in midlevel to surface waters of rivers, lakes, and flooded forests. Most species of this family originate from the Orinoco and ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

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]   |
