Bryconops Rheoruber
''Bryconops rheoruber'' is a species of freshwater fish from the rivers of Brazil. Its back scales are tan-to-cream, and its belly is silvery; the divide between the two colors is marked by a broad iridescent-silver stripe. Its fins are a mixture of pale, clear, and reddish, which contributed to its specific name. "Rheo" means "flow" or "current" in Greek, and "ruber" means "red" in Latin. It was first described from the rapids of the Rio Xingu (hence "rheo" in its scientific name), and its range is known to extend into the Rio Iriri, the largest tributary therein. Like many other species of ''Bryconops'', it prefers fast-flowing waters over a rocky or sandy substrate. Description ''Bryconops rheoruber'' ranges from 4.61 to 5.49 cm in standard length. This makes it smaller than most ''Bryconops'', members of which are largely between 6 and 8 cm long. It is deep-chested, with its deepest body section just before the dorsal fin, and it has 8–9 pre-dorsal scales; the latter is ...

Tailspot Tetra
The tailspot tetra (''Bryconops caudomaculatus'') is a freshwater fish that lives in the coastal river regions of upper South America. Both its common and scientific names reference the distinct spot of color present on the tail fin, which is one of its defining characteristics. It is a small fish, reaching 4.8 in (12.4 cm) at its longest. Despite its small size, it is an active swimmer, with a preference for fast-flowing waters. Description The tailspot tetra, like the rest of the genus ''Bryconops'', has a slender body described as "smelt-like", similar to members of sister genus ''Piabucus''. It reaches 4.8 in (12.4 cm) in total length (with the tail fin included), and a corresponding weight of 20.1 grams. Its back scales are tinted orange to dark-orange, fading into silver on the belly when the fish is alive. Upon close inspection, the scales are also revealed to have a scattering of minute dots. The spot of bright orange on the basal half of the caudal fin is what gives th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish Of The Amazon Basin
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Most fis ...

Bryconops
''Bryconops'' is a genus of freshwater fish in the family Iguanodectidae from South America. It consists of small fish, all under half-a-foot long, with slender bodies and silvery scales, though there is some mild color variation. Several species can be identified by way of a humeral patch (a mark near the pectoral fin), and others have a reddish ocellus, or eyespot, on one or both lobes of the dorsal fin. Many ''Bryconops'' prefer clearwater environments with a strong current, though some are partial to slow-moving blackwater, and several are endemic to their locale. The majority of species are from Brazil or Venezuela. Rivers and river basins that house species of ''Bryconops'' include the Tapajos, Orinoco, Tocantins, Negro, and Madeira. Few species of ''Bryconops'' have been evaluated as far as conservation status, but most of them are believed to be low-risk species. The greatest threats to population levels come almost entirely in the form of anthropogenic hazards, inclu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Belo Monte Dam
The Belo Monte Dam (''formerly known as'' Kararaô) is a hydroelectric dam complex on the northern part of the Xingu River in the state of Pará, Brazil. After its completion, with the installation of its 18th turbine, in November 2019, the installed capacity of the dam complex is 11,233 megawatts (MW), which makes it the second largest hydroelectric dam complex in Brazil and the fifth largest in the world by installed capacity, behind the Three Gorges Dam, Baihetan Dam and the Xiluodu Dam in China and the Brazilian-Paraguayan Itaipu Dam. Considering the oscillations of flow river, guaranteed minimum capacity generation from the Belo Monte Dam would measure 4,571 MW, 39% of its maximum capacity. Brazil's rapid economic growth over the last decade has provoked a huge demand for new and stable sources of energy, especially to supply its growing industries. In Brazil, hydroelectric power plants produce over 85% of the electrical energy. The Government has decided to cons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Union For Conservation Of Nature

Bryconops Magoi
''Bryconops magoi'' is a small species of fish from South America. It is only found in Venezuela, along with sister species ''Bryconops collettei''. Its tail-fin markings help to differentiate it from various congeners, as does its fairly restricted range. It is most closely related to ''B. collettei'' and ''Bryconops caudomaculatus'', and it was once considered synonymous with the latter; specimens of ''B. magoi'' and ''B. collettei'' both were routinely misidentified as ''B. caudomaculatus'' before being given species distinction. Description ''B. magoi'' has a maximum size within the range of 7.0 cm (2.8 in), which places it to the smaller side of the genus ''Bryconops'' as a whole. Its caudal fin (tail fin) bears a rather diffuse ocellus (eyespot), the upper half of which is colored red; this is a similarity it shares with B. collettei. This eyespot is not well-defined, but is clear against the dark coloration of the caudal fin overall (which is dense in melanophores). Its s ...

Amazon River
The Amazon River (, ; es, Río Amazonas, pt, Rio Amazonas) in South America is the largest river by discharge volume of water in the world, and the disputed longest river system in the world in comparison to the Nile. The headwaters of the Apurímac River on Nevado Mismi had been considered for nearly a century as the Amazon basin's most distant source, until a 2014 study found it to be the headwaters of the Mantaro River on the Cordillera Rumi Cruz in Peru. The Mantaro and Apurímac rivers join, and with other tributaries form the Ucayali River, which in turn meets the Marañón River upstream of Iquitos, Peru, forming what countries other than Brazil consider to be the main stem of the Amazon. Brazilians call this section the Solimões River above its confluence with the Rio Negro forming what Brazilians call the Amazon at the Meeting of Waters ( pt, Encontro das Águas) at Manaus, the largest city on the river. The Amazon River has an average discharge of about – ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
