The Malayan field rat, Malaysian field rat or Malaysian wood rat, (Rattus tiomanicus) is a species of rodent in the family Muridae. It is nocturnal and mainly arboreal and is found in Malaysia, Thailand, Indonesia and the Philippines. It is a common species and the International Union for Conservation of Nature has assessed it as being of "least concern".
The Malayan field rat has a head-and-body length of 140 to 190 mm (5.5 to 7.5 in) and a tail 150 to 200 mm (6 to 8 in). It has a weight of between 55 and 150 g (2 and 5 oz). The ears are large and nearly naked. The fur is smooth and flattened, interspersed with short spines. The dorsal pelage is a grizzled olive-brown with scattered medium-length black guard hairs, and the underparts are whitish. The tail, which is a similar length to the body, is a uniform dark brown. The feet are broad, and the soles have fine ridges for climbing. It differs from Annandale's rat (Rattus annandalei) in having sleek fur with spines and fewer mammae, and from the ricefield rat (Rattus argentiventer) in having plain white underparts and lacking an orange spot in front of the ear.

The Malayan field rat is known from Malaysia, Thailand, Sumatra, Borneo, the Philippines and many smaller islands. [1] Its typical habitat is primary and secondary forest, including coastal forest but it is seldom found in dipterocarp forests. It is also found in plantations, shrubby areas, grassland and gardens, but seldom invades buildings. [2]
The Malayan field rat is nocturnal. It climbs well and spends much of its time in trees as well as foraging on the ground. It hides in log piles, heaps of palm fronds, under fallen logs and in the crowns of palm trees. It feeds on both vegetable and animal matter, with oil palm fruits forming part of its diet. [2]
The Malayan field rat is an abundant and adaptable species with a very wide range, a large total population and an ability to live in a number of different environments. No particular threats have been identified, and in some areas it is regarded as a pest. The International Union for Conservation of Nature has assessed its conservation status as being of "least concern". [1]
Rattus is a genus of muroid rodents, all typically called rats. However, the term rat can also be applied to rodent species outside of this genus.
The otter civet is a semiaquatic viverrid native to Thailand, Malaysia, Indonesia and Brunei. It is listed as Endangered because of a serious ongoing population decline, estimated to be more than 50% over the past three generations, inferred from direct habitat destruction, and indirect inferred declines due to pollutants.
Hose's palm civet, also known as Hose's civet, is a viverrid species endemic to the island of Borneo. It is listed on the IUCN Red List as Vulnerable because of an ongoing population decline, estimated to be more than 30% over the last three generations and suspected to be more than 30% in the next three generations due to declines in population inferred from habitat destruction and degradation.
The Malayan civet, also known as the Malay civet and Oriental civet, is a viverrid native to the Malay Peninsula and the islands of Sumatra, Bangka, Borneo, the Riau Archipelago, and the Philippines. It is listed as "Least Concern" by IUCN as it is a relatively widely distributed, appears to be tolerant of degraded habitats, and occurs in a number of protected areas.
Ruschi's rat or Ruschi's spiny mouse is a rodent species found in Argentina and Brazil. Some cranial features suggest it may be an archaic relative of the paramo Oldfield mouse. The upper parts are greyish yellow with a darker head and yellowish-white underparts. Fine hairs are mixed with flattened and grooved spines that are most numerous on the back.
Holochilus brasiliensis, also known as the Brazilian marsh rat or web-footed marsh rat, is a species of semiaquatic rodent from South America. It is found in northeastern Argentina, southern and eastern Brazil and in eastern Uruguay.
Tome's spiny rat, also known as Tomes' spiny rat or the Central American spiny rat, is a species of spiny rat distributed from Honduras to Ecuador. The IUCN has assessed its conservation status as being of "least concern".
The pale field rat is a small rat endemic to Australia. It is a nocturnal and herbivorous rodent that resides throughout the day in shallow burrows made in loose sand. Once widespread, the range has become greatly reduced and it is restricted to the grasslands, sedges, and cane-fields at the north and east of the continent. The fur is an attractive yellow-brown colour, with grey or cream at the underside. This medium-sized rat has a tail shorter than its body.
The West African shaggy rat is a species of rodent in the family Muridae. It is found in Benin, Cameroon, Ivory Coast, Gambia, Ghana, Guinea, Guinea-Bissau, Liberia, Mali, Nigeria, Senegal, Sierra Leone, and Togo. Its natural habitats are subtropical or tropical seasonally wet or flooded lowland grassland and swamps. It is a common species and the International Union for Conservation of Nature has rated its conservation status as being of "least concern".
Holochilus chacarius, also known as the Chacoan marsh rat or Chaco marsh rat, is a semiaquatic rodent species in the family Cricetidae. It is found in Argentina and Paraguay within the Gran Chaco.
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 Rajah spiny rat also known as the brown spiny rat is endemic to Thailand and Malaysia, Sumatra, Borneo, and adjacent islands.
The Himalayan field rat, sometimes known as the white-footed Indo-Chinese rat, is a species of rodent in the family Muridae. It has a wide range, being found in India, Bangladesh, Nepal, Bhutan, China, Myanmar, Laos, Thailand, and Vietnam, with introduced populations in Indonesia (widely), Palau, and the Philippines. A common species, the International Union for Conservation of Nature has assessed its conservation status as being of "least concern".
The black-tailed tree rat, also called black-tailed acacia rat or black-tailed thallomys,, is a species of rodent in the family Muridae. It is found in Angola, Botswana, Namibia and South Africa, where its natural habitat is subtropical or tropical dry shrubland. It is both nocturnal and arboreal and makes bulky nests in the trees, often acacias, where it feeds on leaves and buds.
The Chinese pygmy dormouse, is a species of rodent of the family Platacanthomyidae found in China and Vietnam.
The black giant squirrel or Malayan giant squirrel is a large tree squirrel in the genus Ratufa native to the Indomalayan zootope. It is found in forests from northern Bangladesh, northeast India, eastern Nepal, Bhutan, southern China, Myanmar, Laos, Thailand, Malaysia, Cambodia, Vietnam, and western Indonesia.
The Malayan weasel or Malay weasel is a weasel species native to the Malay Peninsula and the islands of Sumatra and Borneo. It is listed as Least Concern on the IUCN Red List.
The Aceh rat is a species of rodent from the family Muridae. The Aceh rat is listed as Data Deficient on the IUCN Red List because only two specimens have ever been recorded, and little is known about the species. The species was first regarded as its own species and then as a subspecies of the Malayan field rat, but was once again considered distinct due to its small body size.
