Mylossoma
''Mylossoma'' is a genus of serrasalmids from tropical and subtropical South America, including the basins of the Amazon, Orinoco, Lake Maracaibo and Paraguay- Paraná. These common fish are found both in main river sections and floodplains. They support important fisheries and based on a review by IBAMA, they are the seventh most caught fish by weight in the Brazilian Amazon. They primarily feed on plant material such as seeds and fruits (to a lesser extent invertebrates), and in their ecology they generally resemble the larger tambaqui (''Colossoma macropomum''). ''Mylossoma'' reach up to in length and in weight. Species There are currently 5 recognized species in this genus:Mateussi, N.T.B., Pavanelli, C.S. & Oliveira, C.

Mylossoma Duriventre
''Mylossoma duriventre'', the silver mylossoma, is a species of freshwater serrasalmid fish endemic to tropical and subtropical South America. It grows to a maximum length of about and a weight of . It is the subject of a local fishery, being known as pacu in Brazil and palometa in Venezuela (names it shares with several relatives). Distribution and habitat As traditionally defined, ''Mylossoma duriventre'' is native to the Amazon, Orinoco and Río de la Plata basins, and to the Tocantins River and its western tributary, the Araguaia River. It prefers nutrient-rich waters but also occurs in the lower stretches of nutrient-poor rivers. In 2018, a review based on DNA and morphometrics restricted its range to the Río de la Plata Basin (Paraguay, lower Paraná and Uruguay rivers). Two species formerly considered synonyms of ''M. duriventre'' have been revalidated: '' M. albiscopum'' of the Amazon and Orinoco basins, and '' M. unimaculatum'' of the Tocantins–Araguaia basin.

Mylossoma Aureum
''Mylossoma aureum'' is a species of serrasalmid native to the Amazon and Orinoco Basins in South America. This species grows to a total length of . This species is of some importance to local commercial fisheries, but less so than the closely related '' M. albiscopum'' of the same region.Mateussi, Nadayca T. B. ; Claudio Oliveira; & Carla S.

Serrasalmidae
The Serrasalmidae (serrasalmids) are a family of characiform fishes, recently elevated to family status. It includes more than 90 species. The name means "serrated salmon family", which refers to the serrated keel running along the belly of these fish. Fish classified as Serrasalmidae are also known by these common names: pacu, piranha, and silver dollar. These common names generally designate differing dental characteristics and feeding habits. Description Serrasalmids are medium- to large-sized characiform fishes that reach about long, generally characterized by a deep, laterally compressed body with a series of midventral abdominal spines or scutes, and a long dorsal fin (over 16 rays). Most species also possess an anteriorly directed spine just before the dorsal fin extending from a supraneural bone; exceptions include members of the genera ''Colossoma'', ''Piaractus'', and ''Mylossoma''. Most serrasalmids have about 60 chromosomes, ranging from 54 to 62.''Metynnis'' has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Animalia
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a bilaterally symmetric body plan. The Bilateria include the protostomes, containing animals such as nematodes, arthropods, flatworms, annelids and molluscs, and the deuterostomes, containing the echinode ...

IBAMA
Brazilian Institute of the Environment and Renewable Natural Resources ( pt, Instituto Brasileiro do Meio Ambiente e dos Recursos Naturais Renováveis, IBAMA) is the Brazilian Ministry of the Environment's administrative arm. IBAMA supports anti-deforestation of the Amazon, and implements laws against deforestation where the government ceases to implement. IBAMA works to keep the forest from loggers, farming, agricultural farm grazing and anything that would threaten the Amazon. Spix's macaw Among IBAMA's diverse environmental and natural resources activities, it manages The Working Group for the Recovery of the Spix's macaw and the associated ''Ararinha Azul'' project for conserving one of the rarest birds in the world. However the last Spix's macaw living in the wilderness disappeared in 2000 and the species became extinct in the wild. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Georges Cuvier
Jean Léopold Nicolas Frédéric, Baron Cuvier (; 23 August 1769 – 13 May 1832), known as Georges Cuvier, was a French natural history, naturalist and zoology, zoologist, sometimes referred to as the "founding father of paleontology". Cuvier was a major figure in natural sciences research in the early 19th century and was instrumental in establishing the fields of comparative anatomy and paleontology through his work in comparing living animals with fossils. Cuvier's work is considered the foundation of vertebrate paleontology, and he expanded Linnaean taxonomy by grouping classes into phylum, phyla and incorporating both fossils and living species into the classification. Cuvier is also known for establishing extinction as a fact—at the time, extinction was considered by many of Cuvier's contemporaries to be merely controversial speculation. In his ''Essay on the Theory of the Earth'' (1813) Cuvier proposed that now-extinct species had been wiped out by periodic catastrophi ...

Louis Agassiz
Jean Louis Rodolphe Agassiz ( ; ) FRS (For) FRSE (May 28, 1807 – December 14, 1873) was a Swiss-born American biologist and geologist who is recognized as a scholar of Earth's natural history. Spending his early life in Switzerland, he received a PhD at Erlangen and a medical degree in Munich. After studying with Georges Cuvier and Alexander von Humboldt in Paris, Agassiz was appointed professor of natural history at the University of Neuchâtel. He emigrated to the United States in 1847 after visiting Harvard University. He went on to become professor of zoology and geology at Harvard, to head its Lawrence Scientific School, and to found its Museum of Comparative Zoology. Agassiz is known for observational data gathering and analysis. He made institutional and scientific contributions to zoology, geology, and related areas, including multivolume research books running to thousands of pages. He is particularly known for his contributions to ichthyological classification, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johann Baptist Von Spix
Johann Baptist Ritter von Spix (9 February 1781 – 13 March 1826) was a German natural history, biologist. From his expedition to Brazil, he brought to Germany a large variety of specimens of plants, insects, mammals, birds, amphibians and fish. They constitute an important basis for today's National Zoological Collection in Munich. Numerous examples of his ethnographic collections, such as dance masks and the like, are now part of the collection of the Museum Five Continents, Museum of Ethnography in Munich. Biography Spix was born in Höchstadt, in present-day Middle Franconia, as the seventh of eleven children. His childhood home is the site of the Spix Museum, open to the public since 2004. He studied philosophy in Bamberg and graduated with a doctoral degree. Later he studied theology in Würzburg. After attending lectures of the young professor Friedrich Wilhelm Joseph Schelling, F. W. J. Schelling, Spix became interested in nature. He quit his theology studi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
