Brachyteles
The muriquis, also known as woolly spider monkeys, are the monkeys of the genus ''Brachyteles''. They are closely related to both the spider monkeys and the woolly monkeys. Species The two species are: They are the two largest species of New World monkey New World monkeys are the five families of primates that are found in the tropical regions of Mexico, Central and South America: Callitrichidae, Cebidae, Aotidae, Pitheciidae, and Atelidae. The five families are ranked together as the Ceboi ...s, and the northern species is one of the most endangered of all the world's monkeys. The muriqui lives primarily in coffee estates in southeastern Brazil. Males are the same size and weight as females. References Further reading * Russell A. Mittermeier, "Monkey in Peril".

Northern Muriqui
The northern muriqui (''Brachyteles hypoxanthus)'' is one of two species of muriqui. They are also known as woolly spider monkey because they exhibit the woollen pelt of woolly monkeys and the long prehensile tail of spider monkeys. Muriquis are the largest extant New World monkeys. They can reach long and weight up to . The northern muriqui is a critically endangered species, it is estimated that there are less than 1,000 mature individuals in the wild. The species is unusual among primates in that males and females are about the same size. Males are no bigger or stronger than females, a factor believed to influence their egalitarian tendencies in social relationships. This species is endemic to the Atlantic Forest region of Brazilian states of Rio de Janeiro, EspÃrito Santo, Minas Gerais and Bahia. Their diets, travel patterns and reproductive cycles are seasonally determined. The size of each group can fluctuate as females move between groups of monkeys. Morphology and id ...

Southern Muriqui
The southern muriqui (''Brachyteles arachnoides'') is a muriqui (woolly spider monkey) species endemic to Brazil. Taxonomy Taxonomy of muriquis is controversial because some scientists believe that they are a monotypic genus while others favor a 2-species classification system. Distribution and habitat Southern muriquis are now found only in specific areas of the Atlantic rainforest located in Brazil, South America, more specifically they are found in the Brazilian states of Paraná, São Paulo, Rio de Janeiro, EspÃrito Santo and Minas Gerais. This New World monkey is known locally as ''mono carvoeiro'', which translates to "charcoal monkey". Description Muriquis are the largest New World monkeys and largest non-human native primates in the Americas. Male muriquis have a head-body length of , with a tail of and a body weight of . Females have a head-body length of , a tail length of and a body weight of . The tails are fully prehensile. The southern muriqui, ''B. ara ...

Spider Monkey
Spider monkeys are New World monkeys belonging to the genus ''Ateles'', part of the subfamily Atelinae, family Atelidae. Like other atelines, they are found in tropical forests of Central and South America, from southern Mexico to Brazil. The genus consists of seven species, all of which are under threat; the brown spider monkey is critically endangered. They are also notable for their ability to be easily Monkey breeding, bred in captivity. Disproportionately long limbs and long prehensile tails make them one of the largest New World monkeys and give rise to their common name. Spider monkeys live in the upper layers of the rainforest and forage in the high canopy, from . They primarily eat fruits, but will also occasionally consume leaves, flowers, and insects. Due to their large size, spider monkeys require large tracts of moist evergreen forests, and prefer undisturbed primary rainforest. They are social animals and live in bands of up to 35 individuals, but will split up to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Étienne Geoffroy Saint-Hilaire
Étienne Geoffroy Saint-Hilaire (; 15 April 177219 June 1844) was a French naturalist who established the principle of "unity of composition". He was a colleague of Jean-Baptiste Lamarck and expanded and defended Lamarck's evolutionary theories. Geoffroy's scientific views had a transcendental flavor (unlike Lamarck's materialistic views) and were similar to those of German morphologists like Lorenz Oken. He believed in the underlying unity of organismal design, and the possibility of the transmutation of species in time, amassing evidence for his claims through research in comparative anatomy, paleontology, and embryology. He is considered as a predecessor of the evo-devo evolutionary concept. Life and early career Geoffroy was born at Étampes (in present-day Essonne), and studied at the Collège de Navarre, in Paris, where he studied natural philosophy under M. J. Brisson. He then attended the lectures of Louis-Jean-Marie Daubenton at the College de France and Fourcroy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monkey
Monkey is a common name that may refer to most mammals of the infraorder Simiiformes, also known as simians. Traditionally, all animals in the group now known as simians are counted as monkeys except the apes. Thus monkeys, in that sense, constitute an incomplete paraphyletic grouping; alternatively, if apes (Hominoidea) are included, ''monkeys'' and ''simians'' are synonyms. In 1812, Étienne Geoffroy grouped the apes and the Cercopithecidae group of monkeys together and established the name Catarrhini, "Old World monkeys" ("''singes de l'Ancien Monde''" in French). The extant sister of the Catarrhini in the monkey ("singes") group is the Platyrrhini (New World monkeys). Some nine million years before the divergence between the Cercopithecidae and the apes, the Platyrrhini emerged within "monkeys" by migration to South America likely by ocean. Apes are thus deep in the tree of extant and extinct monkeys, and any of the apes is distinctly closer related to the Cercopith ...

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

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, Germany, 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 studies and began studying medic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Woolly Monkeys
The woolly monkeys are the genus ''Lagothrix'' of New World monkeys, usually placed in the family Atelidae. Both species in this genus originate from the rainforests of South America. They have prehensile tails and live in relatively large social groups. Taxonomy The following 2 species and 5 subspecies are currently considered to be within the genus: Description Woolly monkeys are closely related to spider monkeys. They have a thick brown coat with dark gray appendages. The stomach area is black and heads are light brown. The fur color is the same for both males and females. Variation in color exist among subspecies. A prehensile tail assists in climbing and fulfills many functions of an opposable thumb. Arm and legs are about equal in length. All species are large, weighing around . Males weigh 45% more than females on average but are of equal length. Habitat and social behaviour Woolly monkeys are found throughout the northern countries of South America (Boliv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
