Squirrels are members of the family Sciuridae, a family that includes small or medium-size 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 to the dormice.
Marmots are large ground squirrels in the genus Marmota, with 15 species living in Asia, Europe, and North America. These herbivores are active during the summer, when they can often be found in groups, but are not seen during the winter, when they hibernate underground. They are the heaviest members of the squirrel family.
Spermophilus is a genus of ground squirrels in the squirrel family. As traditionally defined the genus was very species-rich, ranging through Europe, Asia and North America, but this arrangement was found to be paraphyletic to the certainly distinct prairie dogs, marmots, and antelope squirrels. As a consequence, all the former Spermophilus species of North America have been moved to other genera, leaving the European and Asian species as true Spermophilus.
Xerini is a tribe of ground squirrels occurring in Africa and Asia. With the tribes Marmotini and Protoxerini, they form the subfamily Xerinae. There are five living genera—Xerus, the unstriped ground squirrel; Euxerus, the striped ground squirrel; Geosciurus, the Cape and mountain ground squirrels; Atlantoxerus, containing the living Barbary ground squirrel of North Africa and some extinct species; and Spermophilopsis, containing the long-clawed ground squirrel of Central Asia.
The European ground squirrel, also known as the European souslik, is a species from the squirrel family, Sciuridae. It is among the few European species in the genus Spermophilus. Like all squirrels, it is a member of the rodent order. It is to be found in eastern Europe from southern Ukraine, to Asia Minor, Austria, the Czech Republic, Slovakia, Serbia, Greece, Romania, Bulgaria, North Macedonia and north as far as Poland but the range is divided in two parts by the Carpathian Mountains.
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 Barbary ground squirrel is a species of rodent in the family Sciuridae. It is monotypic within the genus Atlantoxerus. It is endemic to the Atlas mountains in Morocco and some parts in Algeria, and has been introduced into the Canary Islands. Its natural habitats are subtropical or tropical dry shrubland, temperate grassland and rocky areas where it lives colonially in burrows. It was first described by Carl Linnaeus in his landmark 1758 10th edition of Systema Naturae.
The plantain squirrel, oriental squirrel or tricoloured squirrel is a species of rodent in the family Sciuridae found in Indonesia, Malaysia, Singapore, and Thailand in a wide range of habitats: forests, mangroves, parks, gardens, and agricultural areas. Fruit farmers consider them to be pests.
Layard's palm squirrel or flame-striped jungle squirrel is a species of rodent in the family Sciuridae endemic to Sri Lanka. The validity of the subspecies F. l. dravidianus based on a single specimen from the southern tip of India has been questioned, and is probably a juvenile F. sublineatus. Known as මූකලන් ලේනා in Sinhala.
Merriam's ground squirrel is a species of rodent in the family Sciuridae. It occurs in the western United States in Idaho, Nevada, and Oregon.
The Asia Minor ground squirrel, also known as Anatolian souslik, Anatolian ground squirrel, is a species of rodent in the family Sciuridae. It is found in Armenia, Iran, and Turkey. The scientific name roughly translates as "seed-lover with yellow underparts".
The striped ground squirrel is a species of squirrel native to Africa. It was first described by Geoffroy in 1803, but the original publication may be unavailable, so that the binomial authority is today more often cited as "Desmarest, 1817". There are six subspecies. It is a moderately large ground squirrel with sandy-brown or dark-brown fur with a white lateral stripe and whitish underparts. Adults live alone or in pairs in a simple burrow with a central nest, foraging, mostly on the ground, for seeds, nuts and roots, and caching excess food under stones. This 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".
The unstriped ground squirrel is a species of rodent in the family Sciuridae. It is the only member of the genus Xerus. It is found in Djibouti, Eritrea, Ethiopia, Kenya, Somalia, Sudan, Tanzania, and Uganda. Its natural habitats are dry savanna and subtropical or tropical dry shrubland.
The Xerinae comprise a subfamily of squirrels, many of which are highly terrestrial. It includes the tribes Marmotini, Xerini, and Protoxerini.
The Taurus ground squirrel is a species of rodent in the family Sciuridae. It is endemic to the Taurus Mountains of Turkey. It was first identified as a distinct species to the Asia Minor ground squirrel in 2007.
Spermophilus brevicauda is a species of rodent in the family Sciuridae. It is found in eastern Kazakhstan and the northern half of the Xinjiang region of China.
The pallid ground squirrel is a species of rodent in the family Sciuridae. It is found in Mongolia and the adjacent Nei Mongol autonomous region.
