The Muroidea are a large superfamily of rodents, including mice, rats, voles, hamsters, lemmings, gerbils, and many other relatives. Although the Muroidea originated in Eurasia, they occupy a vast variety of habitats on every continent except Antarctica. Some authorities have placed all members of this group into a single family, Muridae, due to difficulties in determining how the subfamilies are related to one another. Many of the families within the Muroidea superfamily have more variations between the families than between the different clades. A possible explanation for the variations in rodents is because of the location of these rodents; these changes could have been due to radiation or the overall environment they migrated to or originated in. The following taxonomy is based on recent well-supported molecular phylogenies.
The Muridae, or murids, are either the largest or second-largest family of rodents and of mammals, containing approximately 870 species, including many species of mice, rats, and gerbils found naturally throughout Eurasia, Africa, and Australia.
Dendromurinae is a subfamily of rodents in the family Nesomyidae and superfamily Muroidea. The dendromurines are currently restricted to Africa, as is the case for all extant members of the family Nesomyidae. The authorship of the subfamily has been attributed to both Alston, 1876, and (incorrectly) to G. M. Allen, 1939.
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 subfamily Deomyinae consists of four genera of mouse-like rodents that were previously placed in the subfamilies Murinae and Dendromurinae. They are sometimes called the Acomyinae, particularly in references that antedate the discovery that the link rat, Deomys ferugineus, is part of the clade. Deomyinae is the older name and therefore has priority over Acomyinae.
The term spiny mouse refers to any species of rodent within the genus Acomys. Similar in appearance to mice of the genus Mus, spiny mice are small mammals with bare tails which contain osteoderms, a rare feature in mammals. Their coats are endowed with unusually stiff guard hairs similar to the spines of a hedgehog; this trait is the source of the common name, spiny mouse.
The link rat is a species of rodent in the family Muridae. It is also known by the common name Congo forest mouse. It is native to central Africa.
The Togo mouse, also known as Büttner's African forest mouse or the groove-toothed forest mouse, is a unique muroid rodent known from only two specimens taken from near the type locality of Bismarckburg, near Yege, Togo, in 1890. Its genus is monotypic.
The Western Saharan spiny mouse or Aïr spiny mouse is a species of small, insectivorous rodent in the family Muridae found arid regions of western Africa.
The Cairo spiny mouse, also known as the common spiny mouse, Egyptian spiny mouse, or Arabian spiny mouse, is a nocturnal species of rodent in the family Muridae. It is found in Africa north of the Sahara, where its natural habitats are rocky areas and hot deserts. It is omnivorous and feeds on seeds, desert plants, snails, and insects. It is a gregarious animal and lives in small family groups. It is the first and only known rodent species that exhibit spontaneous decidualization and menstruation.
The Asia Minor spiny mouse is a species of rodent in the family Muridae.
The gray spiny mouse is a species of rodent in the family Muridae found in Ethiopia, Kenya, South Sudan, and Uganda. Its natural habitats are dry savanna, moist savanna, rocky areas, arable land, and rural gardens.
The fiery spiny mouse is a species of rodent in the family Muridae found in Kenya and Tanzania. Its natural habitats are dry savanna and rocky areas. It may be found as a commensal in human habitations.
Kemp's spiny mouse is a species of rodent in the family Muridae. It is found in Kenya, Somalia, and Tanzania. Its natural habitats are dry savanna and rocky areas. It is one of only two mammals, the other being Acomys percivali, which can shed its skin. In addition, it is known to be capable of completely regenerating damaged tissue, including hair follicles, skin, sweat glands, fur and cartilage.
Louise's spiny mouse is a species of rodent in the family Muridae. It is found in Djibouti, Ethiopia, Kenya, and Somalia. Its natural habitats are dry savanna, subtropical or tropical dry lowland grassland, and rocky areas.
The Mullah spiny mouse is a species of rodent in the family Muridae found in Djibouti, Eritrea, Ethiopia, and Somalia. Its natural habitats are subtropical or tropical dry shrubland and rocky areas.
Percival's spiny mouse is a species of rodent in the family Muridae. It is found in Kenya, Somalia, South Sudan, and Uganda. Its natural habitats are dry savanna, subtropical or tropical dry shrubland, and rocky areas. It is one of two known species of mammals, the other being Acomys kempi, capable of completely regenerating damaged tissue, including hair follicles, skin, sweat glands, fur and cartilage.
The eastern spiny mouse or Arabian spiny mouse is a species of rodent in the family Muridae. They have a wide range, having been found in Middle Eastern deserts, as well as being prevalent in riverine forests in Africa. This is the only species of spiny mouse which may have black coloration. Their diet is similar to other species of spiny mouse, consisting mostly of seeds.
