The Peruvian fish-eating rat (Neusticomys peruviensis) is a species of semiaquatic rodent in the family Cricetidae. It is found only in eastern Peru, where it is known from locations at elevations from 200 to 400 m. [1]
The rodent subfamily Sigmodontinae includes New World rats and mice, with at least 376 species. Many authorities include the Neotominae and Tylomyinae as part of a larger definition of Sigmodontinae. When those genera are included, the species count numbers at least 508. Their distribution includes much of the New World, but the genera are predominantly South American, such as brucies. They invaded South America from Central America as part of the Great American Interchange near the end of the Miocene, about 5 million years ago. Sigmodontines proceeded to diversify explosively in the formerly isolated continent. They inhabit many of the same ecological niches that the Murinae occupy in the Old World.
The black-capped squirrel monkey is a species of New-World monkey native to the upper Amazon basin in Bolivia, western Brazil and eastern Peru. They weigh between 365 and 1135 grams and measure, from the head to the base of the tail, between 225 and 370mm. Black-capped squirrel monkeys are primarily tree-dwelling and are found in both native and plantation forests as well as some farmed areas near running water. Their diet is omnivorous and mostly consists of flowers, fruit, leaves, nuts, seeds, insects, arachnids, eggs and small vertebrates. They mostly live in female-dominated troops of around 40 to 75 monkeys, with males having been observed to disperse to live in all-male troops after reaching sexual maturation. Their current conservation status according to the IUCN is 'Least Concern'. The species belongs to the genus Saimiri and has two subspecies, S. b. boliviensis and S. b. peruviensis.
Euryoryzomys nitidus, also known as the elegant oryzomys or elegant rice rat, is a rodent species in the family Cricetidae. Previously it was known as Oryzomys nitidus, but it is not closely related to Oryzomys as that genus is now constructed. Its range includes Bolivia, Brazil and Peru to the east of the Andes, in lowland tropical rainforest as well as forest in the eastern foothills of the mountains, at elevations from 50 to 2,000 m.
Oecomys trinitatis, also known as the long-furred oecomys, long-furred rice rat, Trinidad arboreal rice rat, or big arboreal rice rat, is a species of rodent in the genus Oecomys of family Cricetidae. As currently constituted, it has a wide distribution in Central America and South America, being found in southern Costa Rica, Panama, Colombia, Venezuela, Trinidad and Tobago, Guyana, Suriname, French Guiana, much of Brazil, eastern Ecuador, and eastern Peru.
The montane fish-eating rat is a species of semiaquatic rodent in the family Cricetidae. It inhabits the Andes Mountains of Colombia and Ecuador.

Musso's fish-eating rat is a species of rodent in the family Cricetidae endemic to western Venezuela, where it has been found at altitudes of 1000 to 1200 m. It is semiaquatic and feeds on freshwater invertebrates.
Oyapock's fish-eating rat is a species of rodent in the family Cricetidae. It is found in French Guiana and Brazil.
The Venezuelan fish-eating rat is a species of a Rodent in the Cricetidae family. It is found in Guyana and Venezuela.
Oecomys phaeotis, also known as the dusky arboreal rice rat or dusky oecomys, is a species of rodent in the genus Oecomys of family Cricetidae. It is found on the eastern slopes of the Andes of Peru, at 1500 to 2000 m altitude.
Oligoryzomys arenalis, also known as the sandy colilargo or sandy pygmy rice rat, is a species of rodent in the genus Oligoryzomys of family Cricetidae. It is found in the Andes of Peru at 400 to 2850 m altitude, but may include more than one species.
Nephelomys auriventer, also known as the golden-bellied oryzomys or Ecuadorian rice rat, is a species of rodent in the genus Nephelomys of family Cricetidae. Oldfield Thomas originally described it, in 1899, as a species of Oryzomys, Oryzomys auriventer, and considered it most similar to Oryzomys aureus. In 1926, a subspecies was described from an Ecuadorian locality, Oryzomys auriventer nimbosus, and it was suggested that O. auriventer was closely related to O. albigularis. This proposal was formalized in 1961 by including O. auriventer within the species O. albigularis, but by 1976 O. auriventer was recognized again as a separate species. In 2006, Oryzomys albigularis and related species, including O. auriventer, were transferred to the new genus Nephelomys. Simultaneously, the former subspecies nimbosus was recognized as a separate species, Nephelomys nimbosus.
Nephelomys keaysi, also known as Keays's oryzomys or Keays's rice rat, is a species of rodent in the genus Nephelomys of family Cricetidae. It is found from southeastern Peru to northern Bolivia on the eastern slope of the Andes in Yungas humid forest at altitudes of 1000 to 2600 m. Although its continued existence is not in serious danger and it is listed as "least concern", destruction of its habitat may pose a threat to some populations.
The small hocicudo is a little known species of rodent in the family Cricetidae. It is found in Bolivia and Peru on the eastern slopes of the Andes.
The grey-chinned hermit is a species of hummingbird in the family Trochilidae. It is found in Brazil, Colombia, Ecuador, Peru, and Venezuela.
Pouteria peruviensis is a species of plant in the family Sapotaceae. It is endemic to Peru.
Euryoryzomys macconnelli, also known as MacConnell's rice rat or MacConnell's oryzomys, is a rodent species from South America. It is found in Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname and Venezuela, where it lives in lowland tropical rainforest. It was formerly placed in the genus Oryzomys, as Oryzomys macconnelli, but in 2006 it was reclassified as the type species of the new genus Euryoryzomys.
The Peruvian small-eared shrew is a species of mammal in the family Soricidae. It is known only from northern Peru, where it has been found in shrubby "elfin" cloud forest in the Andes at elevations from 2050 to 3150 m. The species may also be present in Ecuador. It has the southernmost range of any shrew in South America.
