Echimys Vieirai

	Echimys Vieirai ''Echimys vieirai'' is a spiny rat species from South America, described in 2005. It is found in Brazil. The species name ''vieirai'' is a patronym for the Brazilian mammalogist Carlos Octaviano da Cunha Vieira, curator of the Mammal Collection at the Museum of Zoology of the University of São Paulo (MZUSP), from the early 1940s to 1958. The main diagnostic trait of this ''Echimys'' species is the presence of a dorsal median dark maroon stripe on the head. As compared to ''Echimys chrysurus'', ''E. vieirai'' also possesses a darker dorsum. In addition, ''E. vieirai'' can be distinguished from ''Echimys saturnus The dark spiny tree-rat (''Echimys saturnus'') is a species of rodent in the family Echimyidae.

picture info	Echimyidae Echimyidae is the family of neotropical spiny rats and their fossil relatives. This is the most species-rich family of hystricognath rodents. It is probably also the most ecologically diverse, with members ranging from fully arboreal to terrestrial to fossorial to semiaquatic habits. They presently exist mainly in South America; three members of the family also range into Central America, and the hutias are found in the West Indies in the Caribbean. Species of the extinct subfamily Heteropsomyinae formerly lived on Cuba, Hispaniola, and Puerto Rico in the Antilles. Characteristics In general form, most spiny rats resemble rats, although they are more closely related to guinea pigs and chinchillas. Most species have stiff, pointed hairs, or Spine (zoology), spines, that presumably serve for protection from predators. Many echimyids can Autotomy, break off their tails when attacked. This action may confuse predators long enough for the spiny rat to escape. Unlike the tai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Patronym (taxonomy) A species description is a formal scientific description of a newly encountered species, typically articulated through a scientific publication. Its purpose is to provide a clear description of a new species of organism and explain how it differs from species that have been previously described or related species. For a species to be considered valid, a species description must follow established guidelines and naming conventions dictated by relevant nomenclature codes. These include the International Code of Zoological Nomenclature (ICZN) for animals, the International Code of Nomenclature for algae, fungi, and plants (ICN) for plants, and the International Committee on Taxonomy of Viruses (ICTV) for viruses. A species description often includes photographs or other illustrations of type (biology), type material and information regarding where this material is deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9&nbs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]

The MZUSP is an Museum education, educational and research institution that is part of the University of São Paulo. The museum began at the end of the 19th century as part of the Museu Paulista; in 1941, it moved into a dedicated building. In 1969 the museum became a part of the University of São Paulo, receiving its current name. The MZUSP has one of the largest natural-history collections in Latin America, with over 8.5 million preserved specimens of vertebrates (amphibians, mammals, birds, fish and reptiles) and invertebrates (cnidarians, insects, crustaceans, arachnids, myriapods, annelids, mollusks and other marine groups). Each collection is curated independently, and organized according to specific needs. Other facilities in the museum include a library speci ...

picture info	Mammals Described In 2005 A mammal () is a vertebrate animal of the class Mammalia (). Mammals are characterised by the presence of milk-producing mammary glands for feeding their young, a broad neocortex region of the brain, fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles and birds, from which their ancestors diverged in the Carboniferous Period over 300 million years ago. Around 6,640 extant species of mammals have been described and divided into 27 orders. The study of mammals is called mammalogy. The largest orders of mammals, by number of species, are the rodents, bats, and eulipotyphlans (including hedgehogs, moles and shrews). The next three are the primates (including humans, monkeys and lemurs), the even-toed ungulates (including pigs, camels, and whales), and the Carnivora (including cats, dogs, and seals). Mammals are the only living members of Synapsida; this clade, together with Sauropsida (reptiles and birds), constitutes the ...
