Rio Negro (Amazon)
The Rio Negro ( pt, Rio Negro, br ; es, Río Negro} "''Black River''"), or Guainía as it is known in its upper part, is the largest left tributary of the Amazon River (accounting for about 14% of the water in the Amazon basin), the largest blackwater river in the world, and one of the world's ten largest rivers by average discharge. 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 National Reserve, passing several small indigenous settlements on its way, such as Cuarinuma, Brujas, Santa Rosa and Tabaquén. After roughly 400 km the river starts forming the border between Colombia's Department of Guainía and Venezuela's Amazonas State. After passing the Colombian community of Tonina and Macanal the river turns Southwest. Maroa is the first Venezuelan town the river passes. 1 ...

Pyrrhulina Brevis
''Pyrrhulina'' is a genus of freshwater fishes found in tropical South America. Several of these species are popular aquarium fish. ''Pyrrhulina'' is closely related to '' Copeina'' and ''Copella'', although it is distinguished from the former by having only one row of teeth (''Copeina'' spp. have two). When the genus ''Copella'' was established, many species were removed from the genus ''Pyrrhulina'' and placed there, because differences in the maxillary bones in the males had been detected. ''Copella'' species are slimmer and more elongated than those species that remained in the genus ''Pyrrhulina''. Species The 18 currently recognized species in this genus are: * '' Pyrrhulina australis'' C. H. Eigenmann & C. H. Kennedy, 1903 * '' Pyrrhulina beni'' N. E. Pearson, 1924 * ''Pyrrhulina brevis'' Steindachner, 1876 * '' Pyrrhulina eleanorae'' Fowler, 1940 * '' Pyrrhulina elongata'' Zarske & Géry, 2001 * '' Pyrrhulina filamentosa'' Valenciennes, 1847 * '' Pyrrhulina laeta'' ...

Serrasalmus Gouldingi
''Serrasalmus'' is a genus of piranhas. They are collectively known as pirambebas; the "typical" piranhas like the piraya piranha are nowadays placed in ''Pygocentrus''. Like all piranhas, ''Serrasalmus'' are native to South America. These fish are predatory, have sharp teeth and generally have a rhomboid shape. In some, the shape is more ovoid, particularly in old specimens.

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] |
