Mole: description of the animal, how long it lives, what it eats, types

Basic information, external data and lifestyle

• Fact:
  He is very fond of forest edges, railway tracks, clearings, clearings, in general, all places that are open to the sun.
• Fact 2:
  Mole is a loner. It does not form families or even pairs.
• Fact 3:
  Surprisingly, the small animal has as many as 44 teeth. Of these, only 2 upper canines, however, are perfectly developed.
• Fact 4:
  Under good conditions, the animal can live from 4 to 7 years.

An underground mammal with an excellent sense of smell is not particularly loved by summer residents and gardeners. Its ability to dig multi-meter labyrinths of tunnels significantly damages the root system of plants, and piles of dug up earth nullify all the efforts of flower growers who lovingly tend flower beds and lawns.

General description of the species

Moles are a family from the class Mammals, belonging to the order Insectivores. They live in Europe, Asia and North America.

Appearance

The mole looks like a small animal, body length 5–20 grams, weight varies from 9 to 170 grams. Animals are adapted to underground life. The body is rounded, oblong, covered with velvety smooth fur. It always grows straight, which allows it to lie in any direction while digging.

The fur color is black or dark brown. The animal molts in spring, summer and autumn. The paws are small, the front paws are spade-shaped, the hind paws are underdeveloped.

Other external features include:

• small tail;
• a nose made in the form of a movable proboscis;
• absence of ears;
• small oblong head;
• externally invisible neck.

The eyes are poorly developed and lack a retina and lens. The eye openings are small, covered by movable eyelids. In some species, the eyes completely become overgrown. The animals have highly developed senses of hearing, touch and smell.

Characteristic

Moles by nature are predators that eat small insects and larvae. They prefer areas with soft, loose soil that is easy to dig with their paws. In summer, their tunnels are laid close to the soil surface.

In winter, animals go deep into the ground. They do not hibernate, but only greatly reduce their activity. They feed on stocks of worms that are kept alive but paralyzed. To do this, the animal bites off their head.

Habitat

Moles live everywhere in Eurasia and North America. In Russia they are found in the central zone, in the North Caucasus, the Urals and Western Siberia. In the east of the country they live up to the confluence of the Irtysh and the Ob. The northern border of the animals’ habitat runs along the Siberian taiga, and the southern border extends to the forest-steppe zone. All that is important for these animals is that the soil is suitable for digging. They are almost never found in swampy areas.

In Asia, moles are found in China, Turkey, Indochina, Tibet, Mongolia, and Transcaucasia. They are found in the western United States, southeastern Canada, and Mexico.

Population and status

The density of mole populations depends on both the specific species and the area. Males usually increase their density in the spring. In view of this, there are 5–30 individuals per hectare of soil.

Today they have emerged from the status of endangered animals. This is due to the fact that they are almost no longer hunted. Warm winters also have a good effect on the survival of animals.

General information

The mole belongs to the order of insectivores. In Russia and the CIS countries it is very widespread. Prefers meadows with moderately moist soil, forests with deciduous bushes and birch forests. He is very fond of forest edges, railway tracks, clearings, clearings, in general, all places that are open to the sun.

The mole will not settle in coniferous forests, swamps, meadow lowlands, among trees with a powerful root system. The animal needs soil of moderate humidity, black soil with humus. There is plenty of food there - insects, worms, larvae. In areas with strong temperature changes, the animal will stay closer to the forest. Severe winters often cause mass deaths of moles. They live in the upper ground layers, and there will be a clear shortage of food, which will descend much lower underground, hiding from severe frosts.

Burrow construction

The mole spends most of its life underground. Only to develop a new area does it come to the surface. The animal digs two types of tunnels:

• veins;
• search engines

The first ones are also called nests; the mammal rests and hides in them during the cold season. They lie at a depth of 10−90 cm, and their diameter is only 5 cm. Closer to the surface, the mole makes search passages. He digs them so that earthworms and other underground invertebrates live nearby. The network is extensive, it can occupy significant areas - hundreds of square meters. Moles leave traces behind them: soil rollers that appear due to the swollen arches of passages.

The animal digs the ground with its front paws, and rests against the already compacted walls of the hole with its hind paws. At a depth of 10 cm, the mammal can no longer raise its head, so it throws the soil to the surface.

These heaps are called molehills; they reach 15–25 cm in height and up to 1 m in diameter. They are usually gathered in small groups. Molehills are the only sign of the presence of moles on the site that a person can detect.

Lifestyle Features

Mole is a loner. It does not form families or even pairs. The meeting of a male with a relative will be the reason for a brutal fight. Or rather, massacre, because the battle will continue until the death of one of the opponents. The winner eats his victim.

The entire life of the animal passes underground . The burrows have a diameter of 4-6 cm. The passages of the residential areas go from the main cave to the watering hole. The source of life-giving moisture is any body of water: puddles, rivers, ponds, lakes, swamps, etc. The main hole - the nest is insulated with grasses or forest moss.

Animal eye degeneration as a form of natural selection

From the point of view of evolutionary theory, the gradual simplification of the structure of the mole's eyes and the loss of many functions by them is a way of adapting to the lifestyle that this animal leads. Moreover, the regression of the animal’s vision system is associated not only with the lack of need for a clear visual picture, but also with the harmfulness of full-fledged eyes underground.

For example:

1. If a mole had normal large eyes, like, say, rats or mice, then with constant digging of underground passages, earth and dust would get into them. This would lead to eye contamination, inflammation, suppuration and death of animals. The smaller the eyes, the more difficult it is to damage them, and when they are constantly closed with eyelids, they are reliably protected from external influences;
2. Since the sense of smell is much more important for moles, most of the analyzers in the brain are responsibly focused specifically on processing information from olfactory receptors (in star-nosed moles, the sense of touch also plays an important role). The involvement of extensive brain structures in processing visual information would not be rational.

The photo below shows the eye of the Iberian mole:

By and large, moles at this stage of their evolution are moving towards the complete disappearance of their eyes. This form of natural selection, according to different classifications, is:

1. Driving - with it, an advantage in survival is found in animals that deviate from the norm of development of a particular trait. The norm is predominantly open, not very small eyes, but in the case of moles, individuals with constantly decreasing eyes that close with eyelids more often survived. That is, natural selection moves these animals towards complete degeneration of vision.
2. Cutting off, since individuals with “normal” eyes died more often due to eye lesions.

By the way, it is precisely these forms of selection that are characteristic of almost all animals with certain reduced organs. Including for people who have practically degenerated the muscles that move the ear, or, for example, the coccyx, in the place of which their ancestors had a tail.

Molting of moles

The periodic change of fur, molting, in moles occurs not 2 times - in spring and autumn, as in many animals, but 3 or even 4 times, since moles molt in the summer. This is due to the fact that with constant movement through narrow passages, the animal’s fur quickly wears off. It turns out that the mole sheds completely or partially almost all the time, except in winter. In faded areas, the skin darkens and thickens three times, but the hair in this area is weaker and is quickly wiped off.

The mammal's first molt occurs from April to June. Females molt first, and then males. Worn winter fur is replaced with new spring fur. In mid-July, the adults, followed by the young (for the first time in the young), undergo summer molting. Following it, almost without interruption, the autumn molt begins, at the end of which the moles acquire their best appearance. The mole's autumn fur is velvety, shiny, black with a silvery touch, very thick and tall.

Nutrition

The diet of the vast majority of moles consists of earthworms. In second place are insects living in the ground and their larvae, such as wireworms (larvae of click beetles), weevils, mole crickets, beetle larvae (including the May beetle) and flies, and cutworm caterpillars. Many moles eat slugs. Starfish eat aquatic inhabitants: small crustaceans, aquatic insects and fish. Mogers include caterpillars of various species of butterflies in their diet. Scapanus moles and American shrew-moles partly consume plant foods.

Moles feed 5-6 times a day. After each meal, the animal tucks its head and hind legs under its abdomen, taking the shape of a fluffy ball, and falls asleep for about 4 hours. It is during this period of time that food is digested. At one time, an animal can eat about 20-22 g of earthworms, and 50-60 g per day. The mole eats whole or torn worms, starting from the end. Using the teeth and toes of his front paws, he squeezes the soil out of them. Moles are capable of fasting for a maximum of 14 to 17 hours. In summer they eat more food than in winter.

Sometimes moles store food for periods of starvation. From 100 to 1000 earthworms can be collected in underground mole tunnels. Moles immobilize them with a bite to the head, and the worms remain alive for some time.

To search for earthworms, moles do not dig new tunnels every time. They find food in previously made tunnels. The worms themselves crawl into them, attracted by the warmth and smell of the musk secreted by the mole. In winter, earthworms are just as active as in summer. They are able to make moves in frozen ground, crawling to the surface. Moles hunt for them, digging tunnels under the snow.

What do they eat?

The menu mostly consists of invertebrates. They obtain about 90% of their food in feeding passages (tunnels). Moles are omnivores and can eat any food available to them on the site, but most of all they prefer beetle larvae, earthworms and slugs.

In the first half of autumn, the mole stores food supplies near its home. They usually consist of worms, which the animal immobilizes with a bite. The volume of such “preservation” in some cases reaches 2 kg.

Reproduction

Moles breed once a year. The gestation period for the young varies from species to species. In the Siberian mole there is a period when the embryo stops developing for some time.

The breeding season for “Russian” moles is different:

1. The European mate in March-April. The female bears offspring after 35–40 days. The cubs are blind and naked. There are 3–9 moles in a litter, weighing 2–3 g. The female gives birth once a year. Only a fifth of adult moles can produce a second litter in the summer. At 1.5 months the young animals leave the family.
2. The Siberian mate mates in June, but the female gives birth the following year in April–May, since the Altai species has diapause and a total pregnancy of the mole lasts 270 days. There are 3–6 cubs in a litter. In June, young animals consider themselves adults and leave the nest. But sexual maturity in females occurs only after a year, in males after two.
3. The blind mate in February–March while still under the snow. The mole bears offspring for 30 days. There are from 1 to 5 cubs in a litter. These animals grow to the size of an adult within a month, after which they leave the nest.
4. The Caucasian also mates in February. The female brings moles in March. There are 1–3 cubs in a litter. After 40 days they become independent.

With such a small number of young and breeding only once a year, the number of moles in an area can increase very quickly. Since the mole gives birth deep underground, her offspring are not threatened by any predators and all the cubs remain alive.

But how long a mole representative lives depends on its species. The lifespan of the common mole is 4–5 years, the Altai mole is 5 years, the blind mole is 3–4 years, and the Caucasian mole is 5 years.

Natural enemies

Moles don't have many enemies. A specific smell saves them from predators. Sometimes they can still be caught by birds of prey. This happens during spring floods. The animals' enemies are martens, wild boars, badgers, foxes, and raccoon dogs.

The only predator that is the main enemy of the mole is the weasel. She happily sneaks into their passages and catches them. The weasel does not even disdain the musky smell of a mole, which other animals do not like so much.

During the rutting period, the weasel makes a sound that moles always recognize and, sensing danger, run away. Droughts and waterlogging can kill moles. People are also the cause of the death of these animals, as they are capable of killing them either accidentally or intentionally.

Main varieties

The classification of moles implies the existence of over 40 species. Among them, the most common are about one and a half dozen subspecies.

Blind

The main difference from its relatives is the complete absence of eye holes. Individuals are medium-sized, covered with dark brown fur. The range extends to the Caucasus, northern and eastern regions of Turkey, and Iran.

Ussuri mogera

Unlike species that have underdeveloped eyes, the Ussuri mogera has no eyes at all. It is found in the Primorsky Territory of Russia, as well as in northeast China. This is the largest mole among all known species on the planet. Its length can reach 21 cm, and its weight is 300 grams.

Long-tailed

The animal is distinguished by its small body size (8-9 cm) and a relatively long tail, which can reach a length of 4-4.5 cm. It lives in eastern Asia: China, Vietnam.

Caucasian

The name indicates the habitat of the animal. The Caucasian mole is of medium size, dark brown fur, and its tail reaches 3 cm in length.

Starburst

An inhabitant of North America and Canada with a rather unusual appearance. The animal is distinguished by its rather large size: body length - 20 cm, tail length - 7-8 cm. Unlike other moles, the animal has a stigma formed from many movable fleshy processes, reminiscent of the tentacles of a starfish.

Another feature of the starfish is the ability to move through the snow, swim, and dive under ice. In addition to the insects and worms familiar to moles, the starfish eats fish and shellfish caught in the water.

European

Found in Europe and Asia. The animal is of medium size and has a relatively short tail (2-3 cm). The coat color is dark gray, almost black, with the belly being noticeably lighter.

European moles breed once a year, the first coat of the young is light, later the color becomes dark.

East Asian

Animals from the Mole family. They are found in mid-mountain meadows and forests of East and Southeast Asia. Little studied, do not have well described characteristics.

Mogers

Moles with a body length of 9–25 cm and a weight of 290–300 grams. They differ from their relatives of other species in their brownish-brown hair, the specific structure of the auditory apparatus and pelvic bones. There is no fang in the lower jaw. The eyes are covered with leathery membranes and are not visible from the outside.

Ordinary

The animal is known as the European mole. It has a rounded oblong body, an elongated muzzle and a short neck. The limbs are small, adapted for digging. The front legs end in spade-shaped palms that are turned outward. They have powerful claws.

The eyes are partially covered with skin. The hairline is thick and short. This genus is most common in the Mole family.

Japanese shrew

The only representative of the species, so named for its resemblance to shrews. The difference between the species is the ability to live in trees. He can arrange a home for the press both underground and in a nest.

Starfish

Known under the names star-nosed mole, star-nosed mole, star-nosed mole, star-nosed mole. In appearance it is similar to most other moles, but differs in its elongated tail (6–8 cm) and hard fur that does not get wet. There are two skin growths on the face, similar in appearance to an asterisk, which is where the name of the individuals comes from. Animals in adulthood weigh up to 85 g. The eyes are small, but clearly distinguishable in appearance. Lives in the eastern regions of North America.

Western American

The body length of the animal is 11–14 cm, while the tail can take up to 5.5 cm. Body weight reaches 170 grams. The proboscis of the muzzle is moderately elongated. The eyes are small, hidden under the fur. There is no external auricle. The hand of the foot is very wide. The tail is thick, covered with sparse hairs. Distributed in North America.

Short-faced

A small species of the Mole family. Lives in China.

Long-tailed

Lives in Asia. Body length 7–9 cm, weight up to 12 grams. There are no auricles. The front legs are slightly widened and equipped with almost straight claws.

Chinese shrew

Distributed in the Chinese province of Sichuan. It lives mainly in forests of the temperate zone.

Caucasian

Outwardly, it almost completely resembles a European mole. It stands out only for its rudimentary eyes covered with thin skin. It has large teeth and velvety fur. It can burrow to a depth of 1 m. It eats up to 40 g of food per day.

Blind

The smallest mole in our country with a body length of 8–12 cm, weight – no more than 30 grams. The eyes are covered with thin skin. Tail length is about 3 cm.

Japanese mogera

It lives in the southern territories of Japan, as well as in China, Korea and the south of Primorsky Krai. Prefers to live in cultivated fields and meadows.

Where do moles live

Various species of moles are found in North America and Eurasia. Their distribution area is limited to the temperate and subtropical climate zone.

How deep in the ground do moles live?

Moles are constantly on the move and can make up to 50 m of new passages per day. In the occupied territory, animals build a whole multi-tiered system of burrows connected to each other for various purposes.

In loose soil, the mole moves at a depth of 5-10 cm, lifting the soil at the site of the tunnel construction. The depth of the passages in the soil that dries out from above reaches 50 cm. If it is necessary to build passages at great depths, the animal periodically digs vertical branches through which it throws out excess soil. Small earthen mounds are the main sign of the presence of an underground inhabitant on the site. The nest in which it rests between searches for food is located at a depth of 1.5-2 m.

From time to time, the animal makes the rounds of already dug feeding holes in search of prey that has fallen there, and also builds new passages.

What kind of life do they lead?

Moles are almost always underground. All individuals are equally active both at night and during the day. Over the course of a day, animals experience several three- to four-hour stages of increased mobility, and in the intervals between them the animals rest in their nests.

Moles are characterized by a predominantly sedentary lifestyle. Only sometimes, in hot weather and drought, do they move approximately 1–1.5 km from their habitats in search of water.

Moles are loners. They live in their own individual plot, which they bravely defend from enemies to the best of their ability. Each of them has its own tunnel system, but sometimes they overlap. The animals still try not to collide with each other and get food in various secluded corners.

If a mole dies, the neighbors quickly notice it, and the fastest one wins the free area. Sometimes it is shared by several animals.

Having captured a certain territory, moles mark the tunnels laid there with a powerfully smelling secretion secreted by the preputial glands. Both males and females have this smell. If this “aroma” is not present, other individuals will conquer the area.

Mole's labyrinths - system of moves

Under the ground, the mole digs tunnels that can reach depths of several hundred meters. This system of underground passages can be used by several generations of moles. A mole sleeps in a nest lined with dry grass.

When a mole digs the ground, it screws into the soil like a screw, scraping away the soil with its front paws. At this place a molehill is formed (a small hill of earth hiding the entrance to an underground tunnel).

Since the mole does not have incisors, like rodents, it cannot dig in hard soil, so it prefers pliable soil. If there are paths on the mole’s path, he makes a special “underground passage” to get around them. Often other animals also use these crossings.

The mole can also swim across small rivers, but it rarely appears on the surface. It is uncomfortable for him to move on the ground, since he is used to crawling, and the mole also does not see anything.

The entire life of a mole passes in underground passages, which he makes in different layers of soil. Moles dig two types of tunnels:

• residential - passages that are used to move to the nest, watering hole, and feeding areas;
• feed - traps for insects, invertebrates, which the mole eats.

During the night, a mole can build up to 50 m of tunnels. Its nest is located 1.5-2 m underground. As a rule, it is located in a protected place - under stumps, between tree roots, under buildings. The nest is connected to the stern passages using inclined drifts.

The mole's underground tunnel system is multi-tiered. The mole makes its feeding passages closer to the surface. From the outside, they are visible in the form of earthen ridges without earth emissions. The diameter of the underground rooms is 5-5.5 cm.

Molehills.

The mole tunnel is a trap for earthworms. Worms are attracted by the smell of mole musk, as well as by the slightly higher air temperature inside the mole tunnel. The attractiveness of mole tunnels for worms is also enjoyed by shrews, which often climb into them and eat the worms before the host mole. Other animals use the snow mole tunnels - mouse-like rodents, even weasels and stoats.

In open areas of the earth, where the soil often dries out, the mole makes moves at greater depths. In this case, he cannot lift a thick layer of earth, and throws out excess earth through temporary holes (vertical tunnels), called molehills. Sometimes the molehill can reach a size of 70-80 cm.

European moles do not hibernate; they are active all year round. And even in cold winter they can make tunnels in soil that is not frozen.

If the winter is harsh and there is little snow, the ground freezes to a depth of about 0.5 - 5 m, then the mole may die from the cold. Droughts are also dangerous for these animals.

Habitat

How long a mole lives often depends on its habitat. We do not mean specific regions here, since this mammal is distributed everywhere, with the exception of the polar regions and countries with cold or too hot climates.

An important criterion for the habitat of these animals is the looseness of the soil and the abundance of invertebrates in it, which they feed on. This is why moles prefer:

• Clearings in the forest where there are no trees with their powerful rhizomes.
• Meadows in which forbs loosen the soil with their roots and fertilize it, attracting a large number of different larvae and earthworms.
• Broad-leaved and mixed young forests in which moles find attractive edges.

• Farmland where the soil is constantly loosened and cultivated.
• Hilly and mountainous terrain up to the alpine meadow zone.

If nothing disturbs the peace of moles in these places, then they can live up to 7 years.

Number and economic importance of moles

If a mole is at home underground, then on the surface of the earth he is in danger. It can become prey for birds of prey (owls, gulls, herons), as well as foxes and wolves. Therefore, an animal is born, lives and dies in the ground, coming to the surface only in exceptional cases. There he spends a minimum of time, running away into his hole again at the first opportunity.

Moles are numerous animals and do not need protective status. Moles are prized for their fluffy fur. The mole skin is thick and velvety. It was popular in the 19th century. But today it is not used in industry - it turned out that it is not durable.

The benefit of moles is that they exterminate harmful insects and change the structure of the soil, making it looser and enriched with organic matter. Digging tunnels helps ensure that excess moisture from the top layer of soil goes into the lower layers.

But besides the benefits, the mole causes harm to agriculture, especially to people involved in gardening. Digging underground passages, the mole often damages the roots of plants, which leads to disruption of their normal nutrition, causing death. The mole also feeds on earthworms, which are very beneficial for the soil.

They fight mole pests using a variety of methods: by placing products with a pungent odor (onions, garlic) and a rag soaked in kerosene in the mole tunnels. Moles are also repelled with sound signals and ultrasound.

Sense organs

The eyes are small, very poorly developed and almost completely covered with skin. The mole has no ears. The auditory openings are also covered with skin. But the animal’s hearing is remarkably developed.

Which sense organs are better developed in a mole? The frequency sound conductivity of the soil is available to it. The sense of smell is well developed. By smell, he finds food in the ground.

Tactile hairs are distributed throughout the body. Thanks to them, he senses worms located 50-70 cm away from him.

Also an integral part is a 2-centimeter tail, which is covered with hairs. When the mole raises its tail, it feels the ceiling of the dug tunnel. If he does not feel the ground, he returns to his hole.

Beneficial features

The European mole has useful traits. They are expressed in the fact that the animal was previously an object of the fur trade. The mammal has beautiful and durable fur. At the beginning of the last century, moles were hunted for their valuable skins. But the massive catch led to the fact that the animal began to need protection. In 1928 alone, about 20 million skins were harvested.

In the Soviet Union, mole fur clothing became popular in the 1980s. But today in Russia mammals are not hunted, which is why their population has grown. Their numbers also increase due to mild winters, the construction of greenhouses, and the care of lawns and flower beds.

Moles improve the condition of the soil. They make it loose and saturate it with oxygen, which can save the earth from the formation of swamps. Animals destroy pests because they feed on them. Moles eat chafers, mole crickets, and insect larvae.

How to deal with moles?

Moles are very sensitive to sound vibrations. The action of various repellers, mechanical or ultrasonic, is based on this property. But such devices must be placed on the site correctly and thoughtfully - foundations, buried pieces of roofing felt or boards largely dampen the waves.

The second method is to place traps in the passages - mole traps. The method is old, tested and produces results.

With a “war” declared on moles, the question of how moles change their habitat under the influence of unfavorable factors should not arise. The animals simply leave the area.

Mole traps

You can make mole traps with your own hands, but it is better to purchase them in a store to avoid injury when working with metal parts.

Traps and traps are based on different operating principles of their mechanisms:

• Traps that act like spring mousetraps, that is, they crush the victim and break the vertebrae. This device is not inferior in efficiency to others, the only difficulty lies in its installation. These mole traps are placed in twos, in different directions. They need to be installed and masked so that the pressing part does not cling to the arch of the stroke when the mechanism is activated.
• A plunger or harpoon trap is quite easily installed on top of the passage. When a mole touches a guardhouse located in a tunnel, sharp spokes pierce the ground and pierce the animal.
• The scissor trap squeezes the animal from the sides, acting on the principle of scissors. To install, a molehill is dug up, the trap is placed at the bottom of the passage and covered with earth.
• A loop trap is a wire trap for a mole in the form of a loop, which is placed inside the mole passage. When triggered, the mechanism strangles the animal in the loop as it crawls through it.

There are various versions of the above traps in more or less expensive versions, and there are even more homemade traps. But we must take into account that not every person is capable of killing a mole, especially in such a barbaric way.

• Live traps or tunnel traps. If you want to get rid of moles in your dacha in a simple way, but without destroying the animal, you can use other devices - live traps, which help catch the mole. You can make them yourself using cans, plastic bottles and other cylindrical objects, or purchase them at the store. The principle of a live trap is that, once inside the body, the animal cannot get out, since the holes are closed with valves that do not have a reverse action. The animal remains alive and just needs to be taken away from its area and released. Such traps need to be checked regularly so that the mole inside does not die of starvation.

Moles often dig tunnels through which they reach their prey only once. To install mole traps, you need to determine which passages the animals use repeatedly, otherwise your efforts will be wasted and you won’t be able to catch the mole. These passages are deeper, and the ground in them is more compacted.

The most interesting 10 facts about the life of moles

1. The mole stores food. It turns out that this is a very thrifty animal; after hunting, for example, for worms, it does not eat everything at once, but also stores it in a pre-prepared storage facility. Worms can be stored there for quite a long time, and when the time of famine comes, they will be very useful. Sometimes, when excavating passages, its food reserves were discovered; their weight can be up to two kilograms.
2. The animal leads a very active lifestyle all year round and does not hibernate, so it constantly needs a lot of food to replenish its energy. He can eat as much food per day as he weighs. Without food it will not live more than 15-17 hours.
3. Although the animal has blind eyes, it has a very developed sense of smell and hearing.
4. With a weight of no more than 150 grams and a body size of the size of a human palm, thanks to the special structure of the forelimbs (in the form of shovels), a mole is capable of digging a tunnel up to 40 meters with just one knock, and throwing out up to 500 kg of earth. In his home, each tunnel has an average length of 150-200 meters.
5. The animal has simply wonderful fur, the pile does not have any direction, but grows clearly straight. This feature allows you to move freely underground in any chosen direction. The coat sheds 3-4 times a year, but instead a new velvety one grows.
6. An underground inhabitant moves through his tunnel at a speed of 25 m per minute, and is capable of abruptly changing direction. In its usual environment - underground, it is very fast and agile, which cannot be said if it suddenly gets to the surface. Here he is clumsy, since his paws are not designed for walking, so he moves by crawling.

Do you know that there is also a star-nosed mole and a marsupial mole.

1. Many people ask the question “Why is the mole blind?” Of course, he cannot boast of visual acuity, but he is not completely blind. Light and darkness are still distinguished. His eyes are covered with skin, which protects him from soil and microorganisms. According to scientists, genes are responsible for the defective development of eyes in these animals.
2. Upon closer examination, the mole looks like a predatory animal, because its mouth is armed with 44 teeth, including fangs.
3. The freedom-loving animal is not suited to living in captivity. The limited space of artificial burrows is not for them, and even getting used to daily feeding, they die from obesity and inactivity.
4. At the beginning of the twentieth century, mole fur was very popular, at that time it was considered very valuable, but later the opinion changed, since the fur turned out to be quite fragile.

Differences from other mammals

Some people are sure that moles and rodents are the same thing. However, this judgment is far from the truth. Moles have many differences from other rodents:

1. Moles are not endowed with such powerful jaws as are characteristic of rodents, so they live where the soil is very loose. It's easy to make long passes with your paws.
2. Rare rodents can swim, and the mole is an excellent swimmer. It will not be difficult for him to swim across a medium-width river.
3. These shrews are completely unsuited for life on earth. When they accidentally land on the surface, their behavior seems clumsy, since they have almost no vision and are unable to adequately perceive the environment. On the ground they can only move by crawling.
4. Moles are endowed with weak vision, designed to be able to distinguish light from dark. Therefore, with such characteristics, a mole ideally lives only underground.

The following characteristic features distinguish moles from small rodents:

• shortened black fur that is shiny;
• an elongated proboscis in the head, with nostrils at the bottom;
• rather large and widely spaced forelimbs of a spatulate type, the back of which faces upward;
• the hind legs are not large, they are poorly developed;
• small, visually impaired eyes;
• the length of the mole varies from 11 to 21 cm, and the body weight can be about 60-150 grams;
• shortened tail.
