The monito del monte or colocolo opossum, Dromiciops gliroides, also called chumaihuén in Mapudungun, is a diminutive marsupial native only to southwestern South America. It is the only extant species in the ancient order Microbiotheria, and the sole New World representative of the superorder Australidelphia. The species is nocturnal and arboreal, and lives in thickets of South American mountain bamboo in the Valdivian temperate rain forests of the southern Andes, aided by its partially prehensile tail. It eats primarily insects and other small invertebrates, supplemented with fruit.
The harvest mouse is a small rodent native to Europe and Asia. It is typically found in fields of cereal crops, such as wheat and oats, in reed beds and in other tall ground vegetation, such as long grass and hedgerows. It has reddish-brown fur with white underparts and a naked, highly prehensile tail, which it uses for climbing. It is the smallest European rodent; an adult may weigh as little as 4 grams (0.14 oz). It eats chiefly seeds and insects, but also nectar and fruit. Breeding nests are spherical constructions carefully woven from grass and attached to stems well above the ground.
The Old World rats and mice, part of the subfamily Murinae in the family Muridae, comprise at least 519 species. Members of this subfamily are called murines. In terms of species richness, this subfamily is larger than all mammal families except the Cricetidae and Muridae, and is larger than all mammal orders except the bats and the remainder of the rodents.
The wood mouse is a murid rodent native to Europe and northwestern Africa. It is closely related to the yellow-necked mouse but differs in that it has no band of yellow fur around the neck, has slightly smaller ears, and is usually slightly smaller overall: around 90 mm (3.54 in) in length and 23 g in weight. It is found across most of Europe and is a very common and widespread species, is commensal with people and is sometimes considered a pest. Other common names are long-tailed field mouse, field mouse, common field mouse, and European wood mouse. This species is a known potential carrier of the Dobrava sequence of hantavirus which affects humans and may pose serious risks to human health.
Chiropodomys is a genus of Old World rats and mice native to Southeast Asia and northeast India. They are tree-dwelling, very small mice, mostly found in tropical rainforest. In total six extant species have been identified, but only one of these, Chiropodomys gliroides, is common and widely distributed, and has been extensively studied.
The southern big-eared mouse, also known as the southern pericote, is a species of rodent in the family Cricetidae. It is found in Argentina and Chile, and is one of only two species in its genus. The type specimen was captured by Charles Darwin in 1834 along the Santa Cruz River in Argentina, during the voyage of HMS Beagle, and was subsequently described by George Robert Waterhouse.
The Palawan pencil-tailed tree mouse is a species of arboreal rodent in the family Muridae. It is known from lowland forest near sea level, coconut groves, and bamboo thickets. It is endemic to the Palawan Faunal Region in the Philippines. It has been recorded on Balabac, Busuanga, Palawan, Dumaran, and Calauit islands.
Koopman's pencil-tailed tree mouse is a species of arboreal rodent in the family Muridae. It is endemic to Pagai and Siberut islands in the Mentawai Islands, off the western coast of Sumatra in Indonesia. Its natural habitat is tropical primary lowland forest. It is threatened by habitat loss (logging).
The large pencil-tailed tree mouse or greater pencil-tailed tree mouse is a species of arboreal rodent in the family Muridae. It is endemic to Borneo where it is only known from Sabah and Sarawak (Malaysia), although it is likely to also occur in Kalimantan.
The gray-bellied pencil-tailed tree mouse is a species of arboreal rodent in the family Muridae. It is endemic to Borneo where it is known from Gunung Kinabalu and from Long Petak in northern Kalimantan (Indonesia). It probably has wider distribution than currently documented. Its natural habitat is montane tropical forest. It is threatened by habitat loss.
The small pencil-tailed tree mouse or lesser pencil-tailed tree mouse is a species of arboreal rodent in the family Muridae. It is endemic to Borneo where it is only known from Sabah and Sarawak (Malaysia) and from southern Kalimantan (Indonesia), although it likely occurs more widely.
The montane hylomyscus or montane wood mouse is a species of rodent in the family Muridae. A long-coated species with brownish-grey upper parts and whitish-grey underparts, it occurs in the uplands of tropical Central Africa where its natural habitat is tropical moist montane forests.
Irenomys tarsalis, also known as the Chilean climbing mouse, Chilean tree mouse, or long-footed irenomys, is a rodent found in Chile, from about 36° to 46°S, and in adjacent Argentina, mainly in forests. It is a large, long-tailed, soft-furred mouse characterized by grooved upper incisors and specialized molars with transverse ridges, divided by deep valleys, which are connected by a transverse ridge along the midline of the molars.
Oligoryzomys longicaudatus, also known as the long-tailed colilargo or long-tailed pygmy rice rat, is a species of rodent in the genus Oligoryzomys of the family Cricetidae. It is found in the southern Andes of Chile and Argentina, with an outlying population in eastern Argentina. As a common species with a wide range and a stable population, the International Union for Conservation of Nature has rated this rodent as being of "least concern".
The cotton mouse is a species of rodent in the family Cricetidae found in the woodlands of the US South.
The tawny deer mouse or marsh mouse is a species of rodent in the family Cricetidae. It is found only in Mexico.
The heavy-browed mouse opossum, or Anderson's mouse opossum, is a species of opossum in the family Didelphidae. It is endemic to a restricted range in southern Peru. This opossum inhabits forests; it is nocturnal and probably arboreal.
Robinson's mouse opossum is a species of opossum in the family Didelphidae. It is found in Belize, Colombia, Ecuador, Grenada, Honduras, Panama, Peru, Trinidad and Tobago, and Venezuela.
Hydromyini is a very large, diverse tribe of muroid rodents in the subfamily Murinae. They are the dominant native rodents in Australasia and one of only two native rodent groups there, the other being the R. fuscipes group of the genus Rattus in the tribe Rattini. They are also found in parts of Southeast Asia.
