The northern water rat (Paraleptomys rufilatus) is an endangered species of rodent in the family Muridae found in the highlands of New Guinea.
The northern water rat is a rodent of the genus Paraleptomys appearing on New Guinea. This species is found at altitudes of 1,200–1,800 metres (3,900–5,900 ft) in the North Coast Ranges, the mountains Mount Dafonsero (Cyclops Mountains, Indonesia), Mount Somoro (Torricelli Mountains, Papua New Guinea) and Mount Benawa (Bewani mountains, Papua New Guinea). This species has a small, fragmented distribution and is probably quite rare. They are probably partly active during the day. By Olo (the local tribe on Mount Somoro in Sandaun Province), this animal is referred to as "timbri".
P. rufilatus is larger than the other species of the genus, P. wilhelmina , and is less uniform in colour; the throat is white and the flanks are orange-like, while both body parts are brown in P. wilhelmina. The head-body length is 118–135 millimetres (4.6–5.3 in), tail length 127–146 mm (5.0–5.7 in), the hind foot length 30–35 mm (1.2–1.4 in), ear length 17–20 mm (0.67–0.79 in) and weighs 54–58 grams (1.9–2.0 oz).
The earless water rat is a New Guinea rodent, part of the Hydromys group of the subfamily of Old World rats and mice (Murinae). It is the only species of the genus Crossomys. This species is probably most closely related to Baiyankamys. It is still unclear to which species this group is related. It is one of the most aquatically adapted rodents of the world.
Paraleptomys is a genus of rodent from New Guinea. It is considered part of the New Guinea Old Endemics, meaning it was part of the first wave of murine rodents to colonize the island. Members of the genus are similar to those in Leptomys but differ in that they do not have elongated hind feet or a third molar. Little is known of the two species' biology.
The Luzon montane forest mouse is a species of rodent in the family Muridae, from the genus Apomys. It occurs only in the Philippines, where it has been found on the large northern island Luzon. It is most closely related to the large Mindoro forest mouse, which occurs on Mindoro. There may be another related species in the Sierra Madre, but this species is yet undescribed. The Luzon montane forest mouse is a relatively large, ground-dwelling rat with a tail that is quite short for its genus.
The Mount Oku rat is a species of rodent in the family Muridae. The genus Lamottemys is monotypic, and this is the only species. It is found only in Cameroon where its natural habitat is subtropical or tropical moist montane forests. It is threatened by habitat destruction.
The gray tree rat is a species of rodent in the family Muridae and the only species in the monotypic genus Lenothrix. It is found in forests in Indonesia and Malaysia. A common species, the IUCN has rated it as being of "least concern".
The long-footed water rat is a species of rodent in the family Muridae. It is found in the mountains of southern Papua New Guinea. Its natural habitat is subtropical or tropical dry forest.
Ernst Mayr's water rat is a species of rodent in the family Muridae, named for evolutionary biologist Ernst Mayr. It is found in the Foja Mountains of Papua Province, Indonesia, and in the mountains of northeastern Papua New Guinea.
The Mindanao mountain rat or long-tailed moss mouse, is a species of rodent in the family Muridae. It is found only in the Philippines, where it is present at high altitudes in the Kitanglad Mountain Range on the island of Mindanao.
The Colombian rice rat, also known as the white-footed Handley's mouse is a species of rodent in the family Cricetidae occurring only in Colombia. It was previously included in Oryzomys, but closely resembles the dusky montane rat, and accordingly both species were placed in the new genus Handleyomys in 2002.
Nephelomys levipes, also known as the nimble-footed oryzomys or light-footed rice rat, is a species of rodent in the genus Nephelomys of family Cricetidae. It is found on the eastern slope of the Andes from southeastern Peru into west-central Bolivia in cloud forest at elevations from 1,800 to 3,200 metres. It occurs in the same general area as its congener N. keaysi, but at higher altitudes.
The short-haired water rat is a species of rodent in the family Muridae. It is found in West Papua, Indonesia and Papua New Guinea. There are two currently undescribed species allied with this taxon.
Stein's rat, also known as the small spiny rat, is a species of rodent in the family Muridae. It is found in West Papua, Indonesia and Papua New Guinea.
The glacier rat is a species of rodent in the family Muridae. It is endemic to the New Guinea Highlands near Puncak Trikora and Puncak Jaya, West Papua, Indonesia. Its altitudinal range is 3,225–4,500 m (10,581–14,764 ft) above sea level.
Xeromys myoides, also known as the water mouse, marine mouse, mangrove mouse, false water rat, manngay and yirrkoo, is a species of rodent native to waterways of Australia and Papua New Guinea.
Aphantophryne minuta is a species of frog in the family Microhylidae. It is endemic to Papua New Guinea and is known from its type locality near Myola Guest House in the Owen Stanley Range, Northern Province, from another locality in the same province, Mount Tafa; only a single specimen is known from each locality. The specific name minuta refers to the very small size of this species. Common name Myola Guinea frog has been coined for it.
German's one-toothed moss mouse is a species of rodent in the family Muridae which occurs in the mountains of southeastern New Guinea.
Oryzomys antillarum, also known as the Jamaican rice rat, is an extinct rodent of Jamaica. A member of the genus Oryzomys within the family Cricetidae, it is similar to O. couesi of mainland Central America, from where it may have dispersed to its island during the last glacial period. O. antillarum is common in subfossil cave faunas and is also known from three specimens collected live in the 19th century. Some historical records of Jamaican rats may pertain to it. The species probably became extinct late in the 19th century, perhaps due to the introduction of the small Indian mongoose, competition with introduced rodents such as the brown rat, and habitat destruction.
Petter's tufted-tailed rat is a rodent in the genus Eliurus found in lowland eastern Madagascar. First described in 1994, it is most closely related to the smaller Eliurus grandidieri. Virtually nothing is known of its natural history, except that it occurs in rainforest and is nocturnal and solitary. It is threatened by destruction and fragmentation of its habitat and is listed as "Vulnerable" on the IUCN Red List.
Dollman's melomys is a species of rodent from the family Muridae. It lives in the eastern highlands of Papua New Guinea at an elevation of at least 1,200 metres (3,900 ft) and on the slopes of Mount Hagen and Mount Sisa. However, it is not found east of the Okapa area. It is an arboreal species occurring in montane secondary and degraded forest, preferring moist tropical environments. Formerly considered to be a subspecies of the black-tailed mosaic-tailed rat, the Dollman's melomys is also often listed as its binomial synonym, Melomys gracilis. The melomys is listed as Least Concern by the IUCN Red List due to its wide range, lack of threats, and tolerance of disturbance.
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.
