Nectomys
''Nectomys'' is a genus of rodent in the tribe Oryzomyini of family Cricetidae. Musser and Carleton, 2005. It is closely related to ''Amphinectomys'' and was formerly considered congeneric with ''Sigmodontomys''. It consists of five species, which are allopatrically distributed across much of South America: ''Nectomys grandis'' in montane Colombia; ''Nectomys palmipes'' on Trinidad and in nearby Venezuela, ''Nectomys apicalis'' in the western margins of the Amazon biome, ''Nectomys rattus'' in much of Amazonia, and ''Nectomys squamipes'' in the Atlantic Forest of Brazil. These species are generally semiaquatic In biology, semiaquatic can refer to various types of animals that spend part of their time in water, or plants that naturally grow partially submerged in water. Examples are given below. Semiaquatic animals Semiaquatic animals include: * Verte ..., are normally found near water, and are commonly called water rats.

Nectomys Squamipes
''Nectomys squamipes'', also known as the Atlantic Forest nectomys, South American water rat, or scaly-footed water rat, is a semiaquatic insectivorous rodent species. It is from Argentina, Brazil, and Paraguay — found primarily near forest rivers and streams in the Atlantic Forest ecoregion. Description ''Nectomys squamipes'', or the South American water rat can be distinguished from other Sigmodontinae based on their size and morphology of their hindfeet. They are the largest of the family (average of 216g) and have long hind legs with partially webbed feet to aid in swimming and have completely scaled heels. ''Nectomys'' is derived from Greek words meaning "mouse" and "swimming". One unique morphological characteristic is the distinct primitive cuspidate pattern of their cheekteeth, which have hypsodont molars, teeth crowned earlier in life and the outer fold of the upper molars tend to be more isolated as enamel islands. The ''Nectomys squamipe'' tends to have relativel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nectomys Rattus
''Nectomys rattus'', the small-footed bristly mouse, Amazonian nectomys, Amazonian mouse,Musser and Carleton, 2005 or common water rat is a species of rodent in the genus ''Nectomys'' of family Cricetidae. It is found in Brazil, Colombia, French Guiana, Guyana, Suriname, and Venezuela, where it lives in a variety of habitats including lowland tropical rainforest, cerrado and caatinga. It is mainly found in areas close to water. It was recognized as distinct only in 2000 and its limits with other ''Nectomys'', including '' Nectomys apicalis'' and ''Nectomys squamipes ''Nectomys squamipes'', also known as the Atlantic Forest nectomys, South American water rat, or scaly-footed water rat, is a semiaquatic insectivorous rodent species.

Oryzomyini
Oryzomyini is a tribe of rodents in the subfamily Sigmodontinae of the family Cricetidae. It includes about 120 species in about thirty genera,Weksler et al., 2006, table 1 distributed from the eastern United States to the southernmost parts of South America, including many offshore islands. It is part of the clade Oryzomyalia, which includes most of the South American Sigmodontinae. The name ''Oryzomyini'' derives from that of its type genus, ''Oryzomys'', which means "rice rat" or "rice mouse". Many species are also known as rice rats. Taxonomy Contents of Oryzomyini An oryzomyine group was first envisaged by Oldfield Thomas in the early 20th century. He defined it to include pentalophodont species, which have a mesoloph(id) on the upper and lower molars, with a long palate (extending past the third molars). Thomas included ''Oligoryzomys'', ''Oecomys'', and ''Oryzomys'' (which included many species now in other genera), as well as '' Rhagomys'', which is currently classified ...

Nectomys Grandis
''Nectomys grandis'', also known as the Magdalena-Cauca water rat, is a nocturnal, semiaquatic species of rodent in the genus ''Nectomys'' of family Cricetidae. It is found in western and northern Colombia at altitudes from sea level Mean sea level (MSL, often shortened to sea level) is an average surface level of one or more among Earth's coastal bodies of water from which heights such as elevation may be measured.

Nectomys Apicalis

When it was described as a new genus in 1994, knowledge of the variation within ''Nectomys'' was much more limited than it is now, and it has been suggested that the status of the taxon be re-examined considering this new information.
