Why is it listed in the Red Book
A rare species that lives in a small area. Many researchers consider this species to be a subspecies of the common mole rat. The number is unknown. The decrease is due to the agricultural development of the habitats of this mole rat. Part of the range of the sand mole rat is part of the Black Sea Reserve.
How to find out
Body length 190-275 mm. In morphology, adaptations to the underground way of life are clearly manifested. Body is heavy. The neck is not visible from the outside. The head is shortened, obtuse in front, flattened from above. The eyes are not visible from the outside. Ear in the form of a small skin roller.
The incisors are large, protruding strongly forward from the mouth: the mole rat uses them when digging the earth. The lips close behind the incisors and when digging, the earth does not enter the oral cavity. The limbs are strongly shortened, five-fingered. The nails are well developed. The coat is thick, soft, but rather low. It differs from other species of mole rats in some structural features of the skull. The color of the hairline is dark ocher-brown.
Mole rat family - Familia Spalacidae. There is one genus in the mole rat family: Spalax mole rats. Sometimes mole rats are not allocated to a separate family, but are included in the Muridae family.
Where does it live
The range is completely located in the USSR and covers a very small area of the Nizhnedneprovsky sands (Aleshkinsky sands) on the left bank of the Dnieper in the Kherson region of the Ukrainian SSR. To the east, the range goes approximately to the line Kakhovka - Brilevka, to the south - to Brilevka - Ivanovka and to the west - to the coast of the Dnieper and the Dnieper estuary.
The genus mole rat is genus spalax. There are 3-8 species in the genus mole rats. Apparently, five species lived in the USSR. Three species were included in the Red Book of the USSR: the sand mole rat S. arenarius, the giant mole rat S. giganteus, and the Bukovina mole rat S. graecus.
They live on slightly moist, soddy, sandy soils with grass-wormwood-forb vegetation. Found in birch groves. They feed mainly on the underground parts of various plants. Feeding passages are made at a depth of 40-50 cm. Reproduction has not been studied. The resettlement of young animals was noted in May. Enemies can be various predators.
Sand mole rat is a mammal from the genus of mole rats and a detachment of rodents.
It is generally similar to other representatives of the genus: it has reduced eyes, ears, and a tail. According to typical features, it is closest to the giant mole rat. The body length is about 30 cm, the fur is colored in light gray shades, and the belly does not differ in color from the back.
It lives in the sandy forest-steppe, in the lower reaches of the Dnieper. The main population is located in the Black Sea Biosphere Reserve. Beyond this range, the range is only mosaic.
The mole rat is a highly specialized digger and leads exclusively underground life. Feeding passages are located at a depth of 25 cm, if it is sands and up to 60 in meadows. The area of personal plots can exceed 80 m². Activity depends on feed and season. In winter, the mole rat makes no more than 3 emissions, and in summer the figure increases to 9 per day. For the winter, the animal is carefully stocked. Most of the plants that are abundant in the place of residence are eaten. Enemies of the species are common - fox predators, ferrets, martens. Offspring happen once a year, and it can be 4 cubs.
The threat comes from the management of people in the development of sands and their afforestation. The species is listed in two editions of the Red Book, in the IUCN list.

- with another. In general, this species is usually lighter in color. In particular, the back, head, back and sides of the body of an adult animal are pale, yellowish-yellow-gray in color. The bases of the hair are grey. The forehead and cheeks are dominated by whitish-gray tones with a slight yellowish tint. In the back of the head, pale-yellowish tones are often mixed. The fur of the ventral side is gray, with an admixture of pale-yellowish shades in the abdomen.
The sand mole rat is distributed exclusively within the Nizhnedneprovsky (Aleshkinsky) sands of the Kherson region (the left bank of the Dnieper River south of Kakhovka). According to E. G. Reshetnik (1941), it settles mainly on poorly drained sandy soils of the chernozem type. Absent on loose sands devoid of vegetation - kuchugurs. A characteristic habitat of this species within the Golopristansky district of the Kherson region is abundantly and moderately overgrown sands, mosaically alternating with kuchugurs. It is especially numerous in areas where plant communities are dominated by field eryngium, field wormwood, Ukrainian goat's beard, pearl cornflower, finger pig, Gmelin's bullock, Dnieper thyme, sheep's fescue, couch grass, common blizzard, furrowed fescue, common goloshenus, Colchis sedge, mountaineer sandy, goat. In most cases, the habitats of the sandy mole rat coincide with those of the primrose (Scirtopoda telum Licht.). Within the Ivano-Rybalchansky forested area of the Black Sea Reserve, it is also found in birch groves. It is completely absent on the coast of Tendrovskaya Bay, Tendrovskaya Spit and adjacent islands. The number is quite high (7-10 individuals per 1 ha).
The burrows of the sand mole rat in their structure have much in common with the burrows of the Podolsk mole rat. However, in habitats associated with sandy soil, their feeding passages usually lie at a greater depth than those of the common, Podolsk, and Bukovinian mole rats. So, according to E. G. Reshetnik (1941), the sand mole rat in the conditions of the Nizhnedneprovsk sand arena lays horizontal passages at a depth of 40–50 cm, which is due to sufficient moisture, and, consequently, soil compaction, as well as the temperature threshold, which for this species should not exceed 27 ° C. At a similar depth, the giant mole rat also makes feeding passages (Anisimov, 1938). In addition, the depth of the vertical passages of the sand mole rat usually slightly exceeds 100 cm, which is most likely due to excessive moisture at great depths associated with a rather high level of groundwater. The location of the discarded heaps of earth in relation to the main feeding passage in the sandy mole rat is similar to that in the Podolsky mole rat, since the length of the burrows through which the earth is transported to the outlet usually does not exceed 25 cm. at an angle of approximately 45°. The dimensions of the outbursts of the earth in the sand mole rat approximately coincide with those in the Podolsk mole rat.
Information about the diet of the sand mole rat is extremely scarce. One can only assume that among the food items, for example, the sand mole rat, the plants that are most numerous in the phytocenoses of the habitats of this species predominate. Among them, the most favorite is the goatbeard, the roots of which are found in abundance in the stocks of the animal (Reshetnik, 1941).
Diagnosis. The dimensions are much smaller than those of the giant mole rat (body length 190–234–275 mm; hind foot 22–26–30 mm; condylobasal length of the skull 42.4–51.0–59.0 mm; length of the upper row of permanent molars 8.3–8.7–9.9 mm; the length of the lower row of permanent molars is 7.8–8.1–8.7 mm). The rostral region of the skull is strongly expanded, spatulate. The relative width of the nasal and premaxillary bones is the same as in the previous species. The fronto-nasal and fronto-maxillary sutures, as in the giant mole rat, form an angle with the apex pointing forward. The anterior-outer edges of the zygomatic arches are sharply bent down. The masseter platform is shortened; its length is approximately equal to the distance between the anterior crest of the latter and the suture of the premaxillary and maxillary bones. The alveolar tubercles are removed from the anterior margin of the M1 alveolus by a distance exceeding the length of the first permanent molar or approximately equal to it (in young and semi-adult specimens). The hard palate at the level of the anterior permanent molars is expanded; its width in adult and old specimens is one and a half times or more greater than the length of M1.
The alveolar process of the lower jaw is much higher than the articular one (in adults and old specimens). Description. The rostral region of the skull is generally similar to that of S. giganteus. The nasal opening is enlarged, high; the ratio of its width and height to the length of a row of permanent molars is 78.1–84.6–90.8 and 38.6–43.2–50.0, respectively, in adult and old specimens; 71.8-75.3-79.5 and 35.7-38.0-40.0 in young and semi-adults. The nasal bones are relatively narrow in front; the ratio of their anterior width to the length of the row of permanent molars is 87.5–94.7–100.0 for adults and old ones and 77.6–82.6–87.2 for young and subadults. The length of the nasal bones, like that of the giant mole rat, is in the vast majority of cases less than the combined length of the frontal and parietal bones. The structure of the fronto-nasal and fronto-maxillary sutures is generally similar to that of S. giganteus. However, the nasal bones are on average longer than those of the previous species; the ratio of their length to that of M1–M3 is 241.0–250.6–257.9 in adult and old specimens and 210.5–214.5–216.9 in young and semi-adult specimens. Postorbital constriction, on average, seems to be less pronounced than in the giant mole rat; the ratio of the postorbital width to the length of the row of molars is 71.6–81.3–89.8 in adults and old specimens and 96.5–99.5–102.3 in young and subadult specimens. The fronto-parietal section is elongated.
The parietal bones are shortened, narrowed; the ratio of their length and width (each separately) to the length of a row of permanent molars is 105.2–125.2–137.5 and 33.0–44.2–51.2 in adults and old ones; 113.1-124.5-130.1 and 62.7-68.1-71.1 in young and semi-adults. The nature of the structure of the sagittal crest, fronto-parietal and fronto-temporal sutures is the same as in the previous species. The upper diastema and hard palate are elongated; the value of the diastema-tooth index is 230.0–249.9–266.7 in adult and old specimens and 178.3–184.2–195.2 in young and semi-adult specimens, and the ratio of the length of the hard palate to the length of the row of permanent molars is 363.6–393.4–418.4 and 313.0–321.3–332.1, respectively. . Structural features of the masseter platform, alveolar tubercles and hard palate are noted in the diagnosis. To what has been said above, one can only add that the alveolar tubercles in the sand mole rat are generally less developed than in the giant one. The structure of the anterior zygomatic arches is generally similar to that of S. giganteus. Their anterior-outer edges are strongly deviated downward, forming a zygomatic angle equal to or greater than 45°. The outer wall of the infraorbital foramen is slightly widened from above in adult and old specimens; its smallest width is approximately equal to the length of the anterior permanent molars or even slightly exceeds the latter. The infraorbital foramen itself is relatively higher than in the previous species; its largest diameter (height) exceeds the length of the upper row of permanent molars. Only in some cases do these measurements coincide. The inner crest of fossa glenoidea is sharply defined, the articular surface itself is narrowed and elongated. The base of the occipital bone is expanded, in connection with which the auditory drums are widely spaced. So, the greatest distance between the outer edges of the lateral pharyngeal tubercles significantly exceeds the length of M1-M3. The structure of the auditory drums is generally similar to that of the giant mole rat; the ratio of the width to the length of a row of permanent molars is 90.6–96.1–103.4. The occipital region of the skull is relatively high; the value of the height ratio, the occipital bone, measured from the upper edge of for. magnum, to the maximum width of the occiput - 45.4-51.0-59.3.
Upper incisors extended; the ratio of the width to the anterior-posterior diameter is 108.3–119.0–130.0. Their anterior surface is flattened.
M1(length 2.4–2.6–2.9 mm; width 2.4–2.5–2.9 mm; ratio of width to length 85.7–96.3–108.3) on average, apparently, relatively wider than in the previous species. According to the configuration of the enamel loops of the chafed surface, it resembles the molars of the same name in the giant mole rat, however, the tendency towards separation of the protocone and hypocone in the early stages of wear is more pronounced. The metacone is fused with the posterior collar at all stages of wear. The order of closing incoming loops into marks is the same as in the previous type. In the vast majority of cases, there are two roots - a powerful posterior-internal (formed by fusion of the posterior external and internal roots) and a weak anterior external.
M2(length 2.1–2.3–2.5 mm; width 2.3–2.6–2.9 mm; ratio of width to length 100.0–113.3–126.1) in terms of the nature of the structure of the rubbing surface is generally similar to the molars of the same name in the giant mole rat. There are two roots - a powerful anterior-internal (merged anterior external and internal roots) and a poorly developed posterior external.
M3(length 1.8–1.9–2.4 mm; width 2.0–2.1–2.4 mm) on average relatively narrower and longer than in the previous species; the ratios of width to length and of the latter to that of the previous permanent root are 95.6–109.5–120.0 and 80.0–87.9–100.0, respectively. In young and semi-adult specimens, the protocones and hypocones are in the overwhelming majority of cases fused, and therefore the tooth is characterized by the presence of only one incoming loop in the outer row. External additional tubercle is always absent. The anterior and posterior outer roots are merged with the inner for almost the entire length.
All upper permanent molars are much smaller than those of the giant mole rat.
Lower jaw with elongated diastema; the value of the diastema-tooth index is 100.0–117.4–126.6 in adult and old specimens and 84.3–101.3 in young and semi-adult specimens. The horizontal branch is relatively high; the ratio of its height measured at the level of the posterior margin of the M1 alveolus to the length of the lower row of permanent molars is 118.1–123.0–132.0 in adults and old specimens and, on average, 111.3 in young and semi-adult specimens. The alveolar process is high, in adults and old people it significantly exceeds the articular process in height. The height of this process, measured from the inside, always exceeds the length of the lower row of permanent molars (the value of the corresponding index in the sand mole rat is 102.5–116.6–132.5). Incisura corono-alveolaris is stepped due to the strong development of the anterior ridge of the alveolar process, which also significantly overlaps the coronoid process. The latter in most cases is higher than that of the previous species, although in some specimens a type of structure is observed that is generally similar to that of the giant mole rat. Outer surface rgos. coronoideus is stepped, which is associated with the entry of the crest of the coronoalveolar notch onto it. Depending on the height of the coronoid process, the nature of the structure of the coronary-articular notch also varies: asymmetric with a shortened rgos. coronoideus, symmetrical - with elongated. The ridges of the coronary-alveolar and coronary-articular notches are approximately equally developed in front, and therefore the fossa between them is much deeper than in the previous species. The maxillary opening is elevated to the edge of the coronary-articular notch; removed from the crest of the latter at a distance noticeably less than 2/3 of the length of the condylus. Articular surface rgos. condyloideus narrowed; ratio of width to length 38.8–45.2–48.2.
The lower incisor is extended; ratio of width to anteroposterior diameter 100.0–103.9–109.0.
M1(length 2.4-2.7-2.8 mm; width 2.4-2.5-2.7 mm; ratio of width to length 88.9-93.1-100.0) in young and semi-adult specimens is characterized by an anterior internal tubercle that is not fused with the anterior collar, and therefore with the protoconid - metaconid. In addition, in the early and middle stages of wear, the tooth bears traces of an entoconid. The protoconid and hypoconid are fused at all stages of wear, but a tendency to separation is still observed in very young specimens. An additional tubercle in the external incoming loop is always absent. Since the tooth in the early and middle stages of wear has a free metaconid, the number of incoming loops in the inner row in young and semi-adult specimens is 2. With age, due to the fusion of the metaconid with the anterior collar, the anterior incoming loop is reduced. Sometimes the roots tend to merge.
M2(length 2.2–2.3–2.4 mm; width 2.6–2.7–2.8 mm; ratio of width to length 113.0–117.2–127.2), as in the previous species, expanded. In terms of the configuration of the rubbing surface and the nature of the structure of the roots, it is generally similar to the molars of the same name in the giant mole rat.
M3(length 2.3–2.4–2.6 mm; width 2.1–2.3–2.6 mm; ratio of width to length 88.0–98.9–104.3) relatively narrow. In general, it is similar to the same-named permanent molars of the giant mole rat; however, unlike the latter, protoconids and hypoconids on the teeth of young and semi-adult specimens are separated in the overwhelming majority of cases. The tooth is characterized by the presence of two roots, which in most specimens are fused along almost the entire length.
Measurements. Condylobasal length of the skull 42.4–51.0–59.0 mm; basal length of the skull 39.6–47.4–56.0 mm; length of nasal bones 17.7–20.8–23.9 mm; joint length of parietal and frontal bones 18.2–21.8–24.9 mm; length of parietal bones 9.5–10.8–12.7 mm; length of the upper diastema 15.2–19.8–24.4 mm; length of hard palate 26.5–32.2–38.6 mm; the length of the upper row of permanent molars is 8.3–8.7–9.6 mm; nasal aperture width 6.1–7.1–8.0 mm; incisal width 7.8–9.5–11.2 mm; width of nasal bones in front 6.6-7.9-9.6 mm; rostral width 10.4–12.6–14.7 mm; postorbital width 6.8–7.7–8.8 mm; width of two parietales 4.9–8.0–12.6 mm; width of parietal bone along lambdoid crest 2.9–4.5–6.1 mm; zygomatic width 31.3–39.9–45.6 mm; occiput maximum width 29.2–33.5–40.1 mm; length of auditory tympanum 10.8–12.8–15.0 mm; width of auditory tympanum 7.7–8.4–9.1 mm; upper incisor width 2.6–3.3–4.0 mm; anterior-posterior diameter of the upper incisor 2.2–2.7–3.6 mm; nasal opening height 3.1–3.5–4.8 mm; condylar length of the lower jaw 31.8–36.2–39.0 mm; angular length of the lower jaw 32.6–36.4–38.2 mm; length of the lower diastema 7.0–9.0–10.1 mm; the length of the lower row of permanent molars is 7.8–8.1–8.7 mm; the thickness of the horizontal branch at the M2 level is 4.7–5.3–5.9 mm; internal height of the alveolar process 7.4–9.2–10.6 mm; width of the lower incisor 3.0–3.5–4.0 mm; anterior-posterior diameter of the lower incisor 3.0-3.4-3.9 mm.
The sand mole rat is a form more specialized to a burrowing way of life. This is evidenced by the presence of elongated upper and lower diastemas, a skull that is relatively high in the occipital region, expanded upper and lower incisors, relatively high horizontal branches and an alveolar process of the lower jaw, the latter being also characterized by a strongly developed crest of the coronary-alveolar notch in its anterior section.
At the same time, the species, just like S. giganteus, has retained even more complicated permanent molars, which indicates not only its relative primitiveness in general, but also a more pronounced adaptation to feeding on hard, coarse plant foods, in other words , - to living in a more arid climate than mole rats from the microphthalmus group. The latter is partly confirmed also in the previously described features of the structure of the upper masseter platform (according to the degree of development in the sandy mole rat, it occupies an intermediate position between the giant mole rat and species from the microphthalmus group) and zygomatic arches (massive, strongly deviated downward in the anterior external sections).
Distribution and geological age. Nizhnedneprovskaya sandy arena (Aleshkinsky sands). The western border is the coast of the Dnieper and the Dnieper Estuary, the eastern border is approximately along the Kakhovka-Brilevka line, the southern along the Brilevka-Ivanovka line. The range of the species is, apparently, a relict character. Recent, no fossils known.

To date, the most famous excavating rodent is the mole. And such a representative of the fauna as a giant mole rat remains little known, although it is not inferior in size to a mole. Its brethren (small mole rat, common mole rat and sandy mole rat) are more common and there is more information about them. The sand mole rat is most similar to the giant mole rat in appearance and biology. This animal is also a very interesting species and has its own characteristics that distinguish them from other representatives of excavating rodents.
Sand mole rat
Small mole rat
Common mole rat
Appearance
Body length 20-50 cm. Body oblong oval. Giant gray-brown mole rat. The coat is short and thick. The upper part of the body is usually lighter than the lower part. In older individuals, the fur often becomes white. The eyes are missing. To be more precise, there are eyeballs, but they are hidden under the skin and are practically undeveloped. The nose is large, bare. Mustaches are short. The teeth are represented by only two pairs of incisors (anterior teeth). The legs are short with small claws. External ears are absent, only two holes are visible on the sides of the head. The tail is missing. Long hairs grow on the forehead, cheeks, belly, near the mouth and on the back of the body, which perform the function of touch. (Fig. 1 Mole rat photo)
Spreading
Like the sand mole rat, it lives in the clay and sandy semi-deserts of the Caspian regions of the northeastern Ciscaucasia, in the lower reaches of the Sulak, Terek and Kuma rivers. From r. Kumy to the south goes beyond the line Gudermes - Makhachkala. On the territory of Dogistan, it lives in the Terek-Sulak and Terek-Kuma lowlands. This species is distributed unevenly, in foci, in the form of separate settlements.
Mole mole
Lifestyle
Leads a solitary life. Adults live in separate burrows. Mole rats spend their entire lives underground in total darkness. They dig long holes with many passages and chambers that reach 250 m, at a depth of up to 4 m. They push the soil to the surface with the help of their heads. A large pile of earth accumulates near the hole, with which the rodent closes up the burrow, and next to it digs a new entrance to the hole. Mole rats collect food for the winter in the passages and cover them with earth on both sides; there can be up to 10 such pantries in each hole.
reproduction
Females bring offspring no more than once every two years, in early spring. Each brood has 2-3 cubs. After birth, each cub is naked, but soon they acquire fluffy hair. They stay with their mother for some time after lactation, and by autumn the young are settled and begin an independent life. Sexual maturity occurs in the second year of their life. The cubs that settle are often preyed upon by birds of prey and foxes.
Naked baby mole rat
Nutrition
It eats only vegetable food (about 40 species of plants): dzhuzgun, wheatgrass, kachim, kiyak, wormwood. In captivity, he can eat various vegetables (carrots, beets, potatoes). In the warm season, the mole rat eats the upper part of the plants, and stores the root for the winter.
Maliciousness
Due to the fact that mole rats often live near gardens and household plots, they harm crops, mainly root crops. Emissions of earth from the hole can interfere with agricultural work (cultivation, plowing) and can damage roads near fields.

Fighting methods
Since the mole rat lives underground, it is not easy to fight him. To do this, use mechanical traps or ultrasonic repellers. But these means are ineffective, as the animal deftly avoids them. Considering the low reproductive rate of giant mole rats, the fight against them is not advisable. But if these rodents are massively operating in your garden, then of course you can resort to methods of struggle:
- mole rats are afraid of strong air currents. The burrow can be blown out, and the rodent that crawled out of the other exit of the burrow can be manually disposed of
- rodenticides (poison against rodents) are sold against mole rats, but their use in vegetable gardens where crops are grown for food is not recommended
- another good way to deal with mole rats is to install traps, traps or crossbows near the entrances to the hole
- an ultrasonic repeller is also used in the fight against mole rats. The repeller must be installed evenly throughout the territory and its effect will not keep you waiting long. The repeller acts on the rodent in an irritating way and it immediately leaves the place of exposure to the device. To understand which is better to choose a repeller, you can read the reviews on the relevant sites.
- In order to turn around in its narrow hole and go back, the giant mole rat makes a kind of “somersault”, which is not typical for other excavators.
- the wool of the giant mole rat can be laid in any direction, which allows it to pass smoothly in different directions of the burrow passages
- the shape of the giant mole rat's body resembles a dish of Kazakh cuisine kurt (cottage cheese cake in the form of sausage). The Kazakhs call this animal kurt-tyshkat, that is, a rodent similar to kurt
- unlike the mole, the giant mole rat digs the ground not with its paws, but with its incisors (front teeth). The earth never gets into the mouth of the rodent thanks to the skin on the sides of the mouth
- if the mole rat is on the surface of the earth, then he will be in a stupor for some time, then circle in one place in reverse and finally try to quickly burrow into the ground
- the lack of vision is compensated by an excellent sense of smell and touch
- This rodent is listed in the Red Book of Russia.
Now you know what a mole rat looks like, its lifestyle and features of its biology. The giant mole rat is not found everywhere and even quite rarely, in separate foci, but if a lot of these rodents have divorced in your area, you know how to get rid of it. An ultrasonic repeller is considered the most effective remedy.
