The giant blind mole-rat (Spalax giganteus) is a species of rodent in the family Spalacidae endemic to the North Caucasus region of Russia. [2] It feeds on roots and tubers and lives underground in a burrow that it digs with its teeth.
The giant blind mole-rat is native to the North Caucasus, Chechnya, and southern Kalmykia located between the northern ends of the Caspian and Black Seas. It is restricted to a range of less than 50,000 km2 (19,000 sq mi), and its distribution within that area is quite patchy. It lives underground in burrows in damp, sandy soils in semidesert areas, in river valleys, on plains, in shrubby or reedy areas, and in disturbed and cultivated soils. [1]
The giant blind mole-rat is active all year round. It lives a largely subterranean existence in the burrow that it digs and is believed to be monogamous. Breeding activities usually occur in December and January and females produce litters of two or three young. [1]
Besides using its incisor teeth for gnawing its food of roots and tubers, the giant blind mole-rat uses them to dig burrows. [3] The teeth grow continually and need to be ground down to keep them sharp and functional. This is achieved by grinding the upper and lower teeth together by raising, lowering, and protruding the mandible in a cyclical movement. [3]
Within its range, the giant blind mole-rat has a patchy distribution and is thought to have an actual area of occupancy less than 37,000 km2 (14,000 sq mi). The sandy desert areas in which it lives are of little interest for agriculture, and the International Union for Conservation of Nature, although previously listing it as vulnerable, now lists it as a "least-concern species" in its Red List of Threatened Species.

The Spalacidae, or spalacids, are a family of rodents in the large and complex superfamily Muroidea. They are native to eastern Asia, the Horn of Africa, the Middle East, and southeastern Europe. It includes the blind mole-rats, bamboo rats, mole-rats, and zokors. This family represents the oldest split in the muroid superfamily, and comprises animals adapted to a subterranean way of life. These rodents were thought to have evolved adaptations to living underground independently until recent genetic studies demonstrated they form a monophyletic group. Members of the Spalacidae are often placed in the family Muridae along with all other members of the Muroidea.
Spalax is a genus of rodent in the family Spalacidae, subfamily Spalacinae. It is one of two extant genera in the subfamily Spalacinae, alongside Nannospalax.
The blind mole-rats, also known as the fossorial or subterranean mole rats, are a subfamily (Spalacinae) of rodents in the family Spalacidae, found in eastern Europe and western and central Asia. The hystricognath mole-rats of the family Bathyergidae are completely unrelated, but some other forms are also in the family Spalacidae. Zokors, root rats, and bamboo rats are spalacids also sometimes referred to as mole rats.
The American shrew mole is the smallest species of mole. It is the only living member of the genus Neurotrichus and the tribe Neurotrichini. It is also known as Gibb's shrew mole and least shrew mole. It is not closely related to the Asian shrew mole. The reason that it is called a "shrew mole" instead of being called either a "shrew" or a "mole" is because of its fur, which is a characteristic of shrews and its large head and heavy dentition, which is characteristic of moles.
The blesmols, also known as mole-rats, or African mole-rats, are burrowing rodents of the family Bathyergidae. They represent a distinct evolution of a subterranean life among rodents much like the pocket gophers of North America, the tuco-tucos in South America, and the Spalacidae from Eurasia.
Juliana's golden mole is a golden mole endemic to South Africa. It is listed as an endangered species due to habitat loss and a restricted range. Golden moles are an ancient group of mammals that live mostly below ground. The eponymous Juliana is Juliana Meester, the wife of the South African zoologist who named this species.
The Damaraland mole-rat, Damara mole rat or Damaraland blesmol, is a burrowing rodent found in southern Africa. Along with the smaller, less hairy, naked mole rat, it is a species of eusocial mammal.
The Cape mole-rat is a species of mole-rat endemic to South Africa. It is the only extant species currently described as belonging to the genus Georychus.
The silvery mole-rat, silvery blesmol, or silky mole-rat is a species of mole-rat of East Africa which occurs in southern Kenya, Tanzania, southeastern Democratic Republic of Congo, Mozambique and Malawi. Solitary and aggressive, little is known about its ecology or behavior. It is monotypic in the genus Heliophobius. A common species, the International Union for Conservation of Nature has rated it as being of "least concern".
The Zaisan mole vole, or eastern mole vole, is a species of rodent in the family Cricetidae. It is found in central Asia.
The Middle East blind mole-rat, also known as the Palestine mole-rat or Ehrenberg's mole-rat, is a species of rodent in the family Spalacidae.
The lesser blind mole-rat is a species of rodent in the family Spalacidae. It is found in Albania, Bosnia and Herzegovina, Bulgaria, Croatia, Greece, Hungary, North Macedonia, Moldova, Romania, Serbia, Montenegro, Turkey and Ukraine.
The Cape dune mole-rat is a species of solitary burrowing rodent in the family Bathyergidae. It is endemic to South Africa and named for the Cape of Good Hope.
Mechow's mole-rat is a species of rodent in the family Bathyergidae. It is found in Angola, Democratic Republic of the Congo, Zambia, and possibly Malawi. Its natural habitats are moist savanna, subtropical or tropical dry shrubland, and subtropical or tropical dry lowland grassland. This mole-rat was first described by the German naturalist Wilhelm Peters in 1881. The specific epithet honours the Prussian explorer and naturalist Friedrich Wilhelm Alexander von Mechow.
The Texas pocket gopher is a species of rodent in the family Geomyidae. It is found in Tamaulipas in Mexico and in Texas in the United States.
The sandy blind mole-rat is an endangered species of rodent in the family Spalacidae. It is endemic to Ukraine. It was first identified by Evdokia Reshetnik in 1939.
The greater blind mole-rat is a species of rodent in the family Spalacidae. It is found in Russia and Ukraine.
Baird's pocket gopher or the Louisiana pocket gopher is a species of pocket gopher that is native to the southern United States. In total, there are three almost identical species of eastern pocket gopher; Geomys attwateri, G. bursarius, and G. breviceps. G. breviceps is larger in size, G. attwateri is medium-sized and G. bursarius is a bit smaller. Other than by size variation they are not identifiable by external features. Baird's pocket gophers are small rodents with most of their weight on the top half of their bodies.
The Kazakhstan blind mole-rat or Ural blind mole-rat is a species of rodent in the family Spalacidae. It is endemic to Kazakhstan, along the Ural River basin and the flood plains of the Uil, Temir, and Emba rivers.
Mehely's blind mole-rat is an endangered species of rodent in the family Spalacidae. It is endemic to Romania.
