The white-tailed rat (Mystromys albicaudatus) also known as the white-tailed mouse, is the only member of the subfamily Mystromyinae in the family Nesomyidae. This species is sometimes placed in the subfamily Cricetinae due to similarities in appearance between the white-tailed rat and hamsters, but molecular phylogenetic studies have confirmed that the two groups are not closely related. The subfamily Mystromyinae is sometimes placed within the family Muridae along with all other subfamilies of muroids. [2]
The white-tailed rat is restricted to shrubby areas and grasslands of South Africa and Lesotho. This is an uncommon species, and populations are thought to be declining because of conversion of scrubland to pasture. The International Union for Conservation of Nature has rated it as being an "endangered species". [1]
The white-tailed rat is a fairly large species with a head-and-body length of 163 mm (6.4 in) for males and 144 mm (5.7 in) for females, with a short tail of about 60 mm (2.4 in). The fur is soft, woolly and dense. The head is broad, and the face is mostly grey, with pale spots above the eye and behind the ear in some individuals. The whiskers are long and the ear is rounded and dark-coloured. The upper parts of head and body are greyish-brown flecked with buff; each hair has a grey base and shaft, and a buff or blackish tip. The underparts are whitish-grey, each individual hair having a grey base and shaft and a cream or whitish tip. The tail is colourless and is clad in short white fur. The fore feet have four digits and the hind feet five. The upper surfaces of the fore feet have white hair, as do the sides and upper surfaces of the hind feet. [3]
The white-tailed rat is endemic to South Africa and Lesotho where it is found in grasslands and shrubby areas. It tends to inhabit burrows of meerkats and cracks in the soil during the day and venture out at night. It eats vegetable matter such as seeds and has been known to take insects. The stomach has a ruminant-like digestive action and there are bacteria in the hind gut that ferment the food. Unlike hamsters, white-tailed rats do not have cheek pouches. [3]
The maned rat or (African) crested rat is a nocturnal, long-haired and bushy-tailed East African rodent that superficially resembles a porcupine. The world's only known poisonous rodent, the maned rat sequesters toxins from plants to fend off predators.
The Cricetidae are a family of rodents in the large and complex superfamily Muroidea. It includes true hamsters, voles, lemmings, muskrats, and New World rats and mice. At over 870 species, it is either the largest or second-largest family of mammals, and has members throughout the Americas, Europe and Asia.
The Nesomyidae are a family of African rodents in the large and complex superfamily Muroidea. It includes several subfamilies, all of which are native to either continental Africa or to Madagascar. Included in this family are Malagasy rodents, climbing mice, African rock mice, swamp mice, pouched rats, and the white-tailed rat.
The long-tailed dwarf hamster is a species of rodent in the family Cricetidae. It is found in China, Kazakhstan, Mongolia, and Russia.
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".
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.
The Mount Oku hylomyscus is a species of rodent in the family Muridae. Found only on Mount Oku, Cameroon, in tropical Central Africa, its natural habitat is tropical moist montane forests. It has a very small range and is threatened by habitat destruction, so the International Union for Conservation of Nature has rated its conservation status as being "critically endangered".
The Ethiopian forest brush-furred rat or golden-footed brush-furred rat, is a species of rodent in the family Muridae. It is endemic to Ethiopia where its natural habitat is subtropical or tropical moist montane forests. It is threatened by habitat loss.
Sloggett's vlei rat or ice rat is a species of rodent in the family Muridae. It is found in southern Lesotho and South Africa where its natural habitats are subtropical or tropical high-altitude grassland, swamps, and rocky areas. Its name commemorates Col. Arthur Sloggett who served in South Africa and collected at Deelfontein in 1902. This is a common species and the International Union for Conservation of Nature has rated it as being of "least concern".
Brants's whistling rat or Brants' whistling rat is one of two species of murid rodent in the genus Parotomys. It is found in Botswana, Namibia, and South Africa where its natural habitats are subtropical or tropical dry shrubland and pastureland. It was first described in 1834 by the Scottish zoologist Andrew Smith who named it in honour of the Dutch zoologist and author Anton Brants.
The Ethiopian white-footed mouse or white-footed stenocephalemys is a species of rodent in the family Muridae. It lives in Ethiopia and Eritrea. Its natural habitats are tropical moist montane forest and tropical high-altitude shrubland.
The highveld gerbil is a species of rodent found in Angola, Botswana, Lesotho, Namibia, South Africa, Eswatini, Zambia, and Zimbabwe. Its natural habitats are dry savanna, temperate shrubland, subtropical or tropical dry shrubland, temperate grassland, and temperate desert. This is a common species with a wide range and the International Union for Conservation of Nature has rated it as being of "least concern" as of 2008.
The Guinean gerbil is a species of rodent found in Burkina Faso, Gambia, Ghana, Guinea, Guinea-Bissau, Ivory Coast, Mali, Senegal, Sierra Leone, and possibly Liberia. Its natural habitats are subtropical or tropical dry forests, dry savanna, rocky areas and arable land, but it is mostly found in areas laterite or clay soils, and with variable amounts of vegetation and dense scrub. This species is described as common and has a stable population and a wide distribution, so the International Union for Conservation of Nature has rated its conservation status as being of "least concern".
The gracile tateril or slender gerbil is a species of rodent found in Burkina Faso, Chad, Gambia, Ghana, Guinea, Ivory Coast, Mali, Niger, Nigeria, Senegal, Togo, and possibly Cameroon. Its natural habitats are dry savanna, arable land, pastureland, and rural gardens. It is a common species, sometimes considered an agricultural pest, and the International Union for Conservation of Nature has rated its conservation status as being of "least concern".
Hildegarde's broad-headed mouse or Hildegarde's zelotomys is a species of rodent in the family Muridae. It is found in Central Africa.
Bennett's chinchilla rat is a species of chinchilla rat in the family Abrocomidae. It is found only in Chile where its habitat is Mediterranean-type scrub on the western side of the Andes. The IUCN has assessed its conservation status as being of "least concern".
The woodland dormouse is a species of rodent in the family Gliridae. It is native to southern and eastern Africa and is also known as the African dormouse, African dwarf dormouse, African pygmy dormouse, or colloquially as micro squirrel. Found in limited numbers in the pet trade, it has complicated care requirements compared to other pet rodents. Its natural habitats are subtropical or tropical, moist montane forests and rivers.
Whitaker's shrew is a species of mammal in the family Soricidae. It is found in Western Sahara, Algeria, Morocco, Tunisia. Its natural habitats are subtropical or tropical dry shrubland, rocky and sandy coasts. It is a fairly common species and the International Union for Conservation of Nature has rated its conservation status as being of "least concern".
