Cyanogaster Noctivaga
''Cyanogaster noctivaga'' is a species of characin native to the Rio Negro, Brazil. Its scientific name translates as the blue-bellied night wanderer, referring to its unique appearance and nocturnal habits. It was first described in 2013, having been discovered in October 2011 on a scientific expedition organised by the University of São Paulo, Brazil. Description When alive, ''Cyanogaster noctivaga'' is a transparent fish with a blue belly and reddish gill covers, but it quickly loses its bright colours after death. Its eyes are large, and the shape of its snout and its dentition differs from other characins, marking it out as a new genus. The longest specimen found was long. It differs from other members of the subfamily Stevardiinae in having 8 dorsal-fin rays and four teeth in the inner premaxillary tooth series and i+5 pelvic-fin rays and the presence of a single conical tooth in the outer premaxillary tooth series. There are hooks on the rays of the pelvic and anal fins ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |

Geography Upper course The source of the Rio Negro lies in Colombia, in the Department of Guainía where the river is known as the ''Guainía River''. The young river generally flows in an east-northeasterly direction through the Puinawai Natural Reserve, Puinawai National Reserve, passing several small indigenous settlements on its way, such as Cuarinuma, Brujas, Santa Rosa and Tabaquén.

Species Description
A species description is a formal scientific description of a newly encountered species, typically articulated through a scientific publication. Its purpose is to provide a clear description of a new species of organism and explain how it differs from species that have been previously described or related species. For a species to be considered valid, a species description must follow established guidelines and naming conventions dictated by relevant nomenclature codes. These include the International Code of Zoological Nomenclature (ICZN) for animals, the International Code of Nomenclature for algae, fungi, and plants (ICN) for plants, and the International Committee on Taxonomy of Viruses (ICTV) for viruses. A species description often includes photographs or other illustrations of type material and information regarding where this material is deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stevardiinae
Stevardiidae is a large Family (biology), family of freshwater fish in the Order (biology), 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 Fish anatomy, caudal fin is found almost exclusively in the males of many species of this family, which allows the release and pumping of Pheromone, 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 ''E ...

Paedocypris Progenetica
''Paedocypris progenetica'' (also known as Indonesian Superdwarf Fish) is a species of tiny cyprinid fish endemic to the Indonesian islands of Sumatra and Bintan where it is found in peat swamps and slow flowing blackwater streams. It was discovered by Singaporean ichthyologist Heok Hui Tan in 2006. He has written a description of the fish along with another species of the same genus called '' Paedocypris micromegethes''. It is one of the smallest known fish in the world, together with species such as ''Schindleria brevipinguis'', with the females reaching a maximum standard length of , and the males reaching a maximum st and the smallest known mature specimen, a female, measuring only . It held the record for the shortest known vertebrate until the frog ''Paedophryne amauensis'' was formally described in January 2012, and the parasitic males of the anglerfish ''Photocorynus spiniceps'' are only long. The fish's diet consists of small planktonic rotifers and cladocerans. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
