Anostomus is a small genus of fish in the family Anostomidae found in South America. They are found in the Orinoco and Amazon Basin, as well as various rivers in the Guianas. The genus currently contains five described species. Petulanos was until recently included here.
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. Their scientific name approximately means "mouth on top", from Ancient Greek áno- (ἄνω) "up" + stóma (στόμᾶ) "mouth", in reference to the arrangement of these fishes' mouth opening.
Franz Steindachner was an Austrian zoologist, ichthyologist, and herpetologist. He published over 200 papers on fishes and over 50 papers on reptiles and amphibians. Steindachner described hundreds of new species of fish and dozens of new amphibians and reptiles. At least seven species of reptile have been named after him.
A headstander is any of several species of South American fish, including Anostomus ternetzi, Anostomus anostomus and members of genus Chilodus from the family Chilodontidae. The name derives from their habit of swimming at a 45° angle, head pointed downwards, as if "standing on their heads".
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.
Charax is a genus containing several species of South American tetras, including the glass headstander, C. gibbosus. These fish, among other characteristics, are small and have a rhomboid shape. Some species are semi-translucent.
Chilodus punctatus, known as the spotted headstander or pearl headstander, is a headstander, a type of fish, in the genus Chilodus. The spotted headstander has a body that extends grayish and green colors over his body and sets off the colors with rows of brown specks.
Abramites hypselonotus – known as the marbled headstander or the high-backed headstander – is a member of the family Anostomidae of the order Characiformes. Under normal fish classifying rules, the marbled headstander would be classified as a surface dweller. In reality marbled headstanders – like all headstanders – inhabit the middle and lower portions of the aquarium. In the wild, head standers are often found face down, tail up in narrow vertical rocky fissures.
Striped headstander may refer to the fish species:
Abramites eques, also known as headstander, picúo, or sardina, small teleost fish and is a member of the family Anostomidae of the order Characiformes. This South American species, like Abramites hypselonotus, adopts a head-down swimming posture due to its distinct feeding habit, which is a direct result of the locals that it frequents.
Gnathodolus bidens is a species of headstander endemic to the Orinoco and Casiquiare rivers in Venezuela. It is the only member of its genus.
Petulanos is a genus of headstander from South America. There are currently three described species; one each in the Xingu, Nickerie and Essequibo river basins.
Pseudanos is a genus of headstander from South America, where found in the Orinoco and Amazon Basins.
Rhytiodus is a genus of headstander from the Amazon Basin in South America. There are currently four described species.
Sartor is a genus of headstander endemic to Brazil. The genus is found in the eastern Amazon Basin, specifically in the Xingu, Tocantins, Mapuera and Trombetas basins.
Schizodon is a genus of headstander from South America. Though found widely in tropical freshwater habitats in the continent, the greatest species richness is in the Paraná–Paraguay–Uruguay river basin. They reach up to 40 cm (1.3 ft) in standard length. They are herbivorous, feeding on fruits, seeds, algae, macrophytes, leaves and roots.
Synaptolaemus is a genus of headstanders native to South America, where found in the Orinoco, Casiquiare and Amazon Basin. Synaptolaemus are elongate in shape and overall black with contrasting red, orange or yellow stripes.
Caenotropus is a genus of chilodontid headstanders from South America, found in the Orinoco, Parnaíba, and Amazon Basins, as well as various rivers in the Guianas. The currently described species in this genus are:
Anostomus anostomus, also known as the striped headstander, striped anostomus, and striped anastomus, is a species of fish.
The glass headstander,, is a species of fish in the genus Charax. commonly known as the transparent tetra.
