Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. 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. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists 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. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Catfish
Catfish (or catfishes; order Siluriformes or Nematognathi) are a diverse group of ray-finned fish. Named for their prominent barbels, which resemble a cat's whiskers, catfish range in size and behavior from the three largest species alive, the Mekong giant catfish from Southeast Asia, the wels catfish of Eurasia, and the piraíba of South America, to detritivores (species that eat dead material on the bottom), and even to a tiny parasitic species commonly called the candiru, ''Vandellia cirrhosa''. Neither the armour-plated types nor the naked types have scales. Despite their name, not all catfish have prominent barbels or "whiskers". Members of the Siluriformes order are defined by features of the skull and swimbladder. Catfish are of considerable commercial importance; many of the larger species are farmed or fished for food. Many of the smaller species, particularly the genus ''Corydoras'', are important in the aquarium hobby. Many catfish are nocturnal, [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Loricariidae
The Loricariidae is the largest family of catfish (order Siluriformes), with 92 genera and just over 680 species. Loricariids originate from freshwater habitats of Costa Rica, Panama, and tropical and subtropical South America. These fish are noted for the bony plates covering their bodies and their suckermouths. Several genera are sold as " plecos", notably the suckermouth catfish, ''Hypostomus plecostomus'', and are popular as aquarium fish. Common names Members of the family Loricariidae are commonly referred to as loricariids, suckermouth armoured catfishes, or armoured catfish. The name "plecostomus", and its shortened forms "pleco" and "plec", are used for many Loricariidae, since ''Plecostomus plecostomus'' (now called ''Hypostomus plecostomus'') was one of the first loricariid species imported for the fish-keeping hobby. Some loricariids are not normally considered "plecostomus", such as ''Farlowella'' catfish. In their native range, these fish are known as ''cascudos'' ...

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Takutu River
The Takutu River (Takatu River, Tacutu River) is a river in the Upper Takutu-Upper Essequibo Region of Guyana and Roraima in Brazil. It forms part of the boundary between the two countries. The confluence of the Takutu and Uraricoera Rivers forms the Branco River. The Takutu River's sources almost link with those of the Essequibo River; in the rainy season, flooding links the Takutu to the Rupununi River, a tributary of the Essequibo. The Takutu River Bridge The Takutu River Bridge ( pt, Ponte do Rio Tacutu) is a bridge across the Takutu River, linking Lethem in Guyana to Bonfim in Brazil. It was completed in 2009 and opened on 31 July 2009. Its official inauguration was on 14 September 2009, in th ... establishes an all-weather road connection between Guyana and Brazil.

Uraricoera River
The Uraricoera River (Uraricuera) is a river of Roraima state in northern Brazil. The confluence of the Uraricoera and Takutu Rivers forms the Branco River. Basin The river drains the Guayanan Highlands moist forests ecoregion. Part of the river's basin is in the Roraima National Forest. The Maracá Ecological Station was established by presidential decree on 2 June 1981. The station consists of the island of Maracá between the Santa Rosa and Maracá branches of the Uraricoera River in the municipality of Boa Vista, Roraima, with an area of .

Branco River
The Branco River ( pt, Rio Branco; Engl: ''White River'') is the principal affluent of the Rio Negro from the north. Basin The river drains the Guayanan Highlands moist forests ecoregion. It is enriched by many streams from the Tepui highlands which separate Venezuela and Guyana from Brazil. Its two upper main tributaries are the Uraricoera and the Takutu. The latter almost links its sources with those of the Essequibo; during floods headwaters of the Branco and those of the Essequibo are connected, allowing a level of exchange in the aquatic fauna (such as fish) between the two systems. The Branco flows nearly south, and finds its way into the Negro through several channels and a chain of lagoons similar to those of the latter river. It is long, up to its Uraricoera confluence. It has numerous islands, and, above its mouth, it is broken by a bad series of rapids. Water chemistry As suggested by its name, the Branco (literally "white" in Portuguese) has whitish water that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chaetostoma
''Chaetostoma'', also known as the bristlemouth catfish, is a genus of suckermouth armored catfishes native to South America with one species, '' C. fischeri,'' extending into Panama. Most species inhabit flowing rivers in the lower Andes and its foothills. Some species are kept in unheated aquaria. Species These are the currently recognized species in this genus: * '' Chaetostoma aburrensis'' (Posada, 1909) * '' Chaetostoma anale'' ( Fowler, 1943) * '' Chaetostoma anomalum'' Regan, 1903 * ''Chaetostoma bifurcum'' Lujan, Meza-Vargas, Astudillo-Clavijo, Barriga-S. & López-Fernández, 2015Lujan, N.K., Meza-Vargas, V., Astudillo-Clavijo, V., Barriga-Salazar, R. & López-Fernández, H.

Suckermouth Catfish Of Brazil
In fish, a suckermouth is a ventrally-oriented (inferior) mouth adapted for grazing on algae and small organisms that grow on submerged objects. All Loricariidae possess a suckermouth as do the cypriniform algae eaters of the genus ''Gyrinocheilus'' and other genera. The 'False Siamensis' (Epalzeorhynchus sp. or Garra taeniata) also has this feature. Three genera in Mochokidae, '' Atopochilus'', ''Chiloglanis'', and '' Euchilichthys'', also possess an oral sucker, formed by the lips and part of the barbels. The Loricariidae and members of the genus ''Gyrinocheilus'' are further adapted by having a special opening on the gill cover so that the fish can breathe without using its mouth. Additionally many other fish of the order Cypriniformes have developed a sucking ability to a lesser or greater extent: *The Hillstream loaches (family Balitoridae) have modified fins to attach themselves to a surface and a ventrally located mouth. *The sucker fish (family Catostomidae) also have a mod ...
