Squirrels are members of the family Sciuridae, a family that includes small or medium-sized rodents. The squirrel family includes tree squirrels, ground squirrels, and flying squirrels. Squirrels are indigenous to the Americas, Eurasia, and Africa, and were introduced by humans to Australia. The earliest known fossilized squirrels date from the Eocene epoch, and among other living rodent families, the squirrels are most closely related to the mountain beaver and dormice.
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 North American porcupine, also known as the Canadian porcupine, is a large quill-covered rodent in the New World porcupine family. It is the second largest rodent in North America after the North American beaver. The porcupine is a caviomorph rodent whose ancestors crossed the Atlantic from Africa to Brazil 30 million years ago, and then migrated to North America during the Great American Interchange after the Isthmus of Panama rose 3 million years ago.
The oribi is a small antelope found in eastern, southern and western Africa. The sole member of its genus, it was described by the German zoologist Eberhard August Wilhelm von Zimmermann in 1783. While this is the only member in the genus Ourebia, eight subspecies are identified. The oribi reaches nearly 50–67 centimetres (20–26 in) at the shoulder and weighs 12–22 kilograms (26–49 lb). It possesses a slightly raised back, and long neck and limbs. The glossy, yellowish to rufous brown coat contrasts with the white chin, throat, underparts and rump. Only males possess horns; the thin, straight horns, 8–18 centimetres (3.1–7.1 in) long, are smooth at the tips and ringed at the base.
The white-tailed antelope squirrel is a diurnal species of ground squirrel, scientifically classified in the order Rodentia and family Sciuridae, found in arid regions of the southwestern United States and the Baja California Peninsula of northwestern Mexico.
The southern Amazon red squirrel, is a squirrel species from South America where it inhabits forests in much of north-western South America east of the Andes. Three subspecies are currently recognised. It is a dark red colour, or a dark brown grizzled with ochre, has whitish underparts and grows to a total length of 48 to 63 cm, including a very long tail. It spends much of its time on the ground in the undergrowth and feeds largely on nuts. Little is known of its breeding habits, but it is a sociable species, several individuals often feeding together in one tree. This squirrel faces no particular threats, has a wide range and is relatively common, and the International Union for Conservation of Nature lists it as a "least-concern species".
Rhabdomys is a largely Southern African genus of muroid rodents slightly larger than house mice. They are known variously as striped or four-striped mice or rats. Traditionally the genus has been seen as a single species, Rhabdomys pumilio, though modern evidence on the basis of karyotype and mtDNA analysis suggests that it comprises two or more species and subspecies. Dorsally Rhabdomys species display four characteristic black longitudinal stripes on a paler background.
The Cape ground squirrel or South African ground squirrel is found in most of the drier parts of southern Africa from South Africa, through to Botswana, and into Namibia, including Etosha National Park.
The Uinta ground squirrel, commonly called a "chisler" and Potgut in northern Utah, is a species of rodent native to the western United States.
The Southern African vlei rat is a species of rodent in the vlei rat genus, Otomys, of the family Muridae in the order Rodentia. This is the type species of the genus. It is native to the grasslands and swamps of southern Africa where it is a common species.
Beecroft's flying squirrel or Beecroft's scaly-tailed squirrel, is a species of rodent in the family Anomaluridae. Some authorities consider it to be monotypic within the genus Anomalurops. Its natural habitats are subtropical or tropical dry forests, subtropical or tropical moist lowland forests, and plantations. It is threatened by habitat destruction but is a common species with a wide range and the International Union for Conservation of Nature has rated its conservation status as being of "least concern".
Pel's flying squirrel or Pel's scaly-tailed squirrel is a species of rodent in the family Anomaluridae. It is found in Liberia, Ivory Coast, and Ghana, where it lives in lowland tropical rainforests. It is named after Hendrik Pel.
The San José Island kangaroo rat is a subspecies of rodent in the family Heteromyidae. It is endemic to Mexico, where it is found only on San José Island off the east coast of Baja California Sur. is restricted to an area of only 30 km2 in the southwestern coast of San José Island, Lower California, with the population having been drastically reduced in size and being close to extinction No other species of Dipodomys occur in sympatry with D. insularis.
The common yellow-toothed cavy is a species of rodent in the family Caviidae, closely related to the domesticated guinea pig. It is found in Argentina, Bolivia, Chile, and Peru. Its karyotype has 2n = 68 and FN = 136. G. musteloides is the most common and widely found member of Galea, and is present at elevations ranging from 20 to 5000 m above sea level. It has yellow teeth.
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.
The red-legged sun squirrel is a species of rodent in the family Sciuridae, also commonly known as the isabelline red-legged sun squirrel. It is native to tropical western and central Africa where its range extends from Senegal in the west, through Nigeria and the Republic of Congo to Uganda and Tanzania in the east. Its natural habitats are subtropical or tropical moist lowland forests and moist savanna. This species is thought to be common and has a very wide distribution, so the International Union for Conservation of Nature has rated its conservation status as being of "least concern".
The Perote ground squirrel is a species of rodent in the family Sciuridae. It is endemic to Mexico and is currently at risk of extinction. Perote ground squirrels live within the same area as rock squirrels but they use different microhabitats. In one case it also shares its habitat with the Mexican ground squirrel.
The southern tree hyrax, also known as the southern tree dassie, is a species of mammal in the family Procaviidae. The southern tree hyrax is mainly found in the south central eastern side of Africa.
The yellow-spotted rock hyrax or bush hyrax is a species of mammal in the family Procaviidae. It is found in Angola, Botswana, Burundi, the Democratic Republic of the Congo, southern Egypt, Eritrea, Ethiopia, Kenya, Malawi, Mozambique, Rwanda, Somalia, northern South Africa, South Sudan, Sudan, Tanzania, Uganda, Zambia, and Zimbabwe. Its natural habitats are dry savanna and rocky areas. Hyrax comes from the Greek word ὕραξ, or shrew-mouse.
Baboons are primates comprising the genus Papio, one of the 23 genera of Old World monkeys, in the family Cercopithecidae. There are six species of baboon: the hamadryas baboon, the Guinea baboon, the olive baboon, the yellow baboon, the Kinda baboon and the chacma baboon. Each species is native to one of six areas of Africa and the hamadryas baboon is also native to part of the Arabian Peninsula. Baboons are among the largest non-hominoid primates and have existed for at least two million years.
