Polar bear (ursus maritimus). Types of bears: photos and names. Types of polar bears Bear is a herbivore or carnivore

Bear is beast of prey, which is the largest in the world. The length of its body reaches approximately three meters, and its mass is approximately 800. The bear has a huge body, strong paws with claws, a short tail, and a large head.

Alexander Sergeevich Pushkin is the first Russian writer of various poems, fairy tales, and riddles. Pushkin's poems became the main point to which the entire Russian people listened. Pushkin’s work contains many works of various genres, but he paid great attention to lyric poetry.

The Bears brown look They live in the taiga, in mountain forests and near fertile meadows near water. The fur of brown bears can be of various colors, ranging from brown tint and ending with dark brown. By old age, bears turn gray and become grey. Species such as the Malayan bear, white-breasted bear, sloth bear, black bear and polar bear are very common. All these types of bears are mostly found alone, but sometimes in groups. They are active at night, but polar bears are active only during the day. Bears rest mainly in caves and pits.


Almost all bears are omnivores. But species such as the polar bear eat only the meat of mammals. Brown bears have a varied diet, which changes due to the changing seasons. After the bear wakes up, its diet includes ants, young shoots and dead animals. The bear's diet also includes various ripe berries and even nuts. Bears eat a lot, in order to feed it they need a lot of food, which is processed into fat necessary for winter living. When the year is not productive, bears eat crops of oats, corn, and also eat domestic animals.


Many bears lead a quiet life throughout the year. Brown bears and white-breasted bears hibernate during the winter. Among polar bears, only female bears that bear cubs hibernate. The bears' den is very clean and emits a pleasant smell.

To the question: Are bears herbivores or predators asked by the author? Elena Yakshigulova the best answer is Bears are omnivores. They eat grass, berries, mushrooms, they will not refuse fish, especially meat, they put on fat - they eat everything until they are completely stupefied.
But pandas only eat bamboo, and polar bears prefer the fat of seals and seals.

Bears (lat. Ursidae) are a family of mammals from the order Carnivora. They differ from other representatives of canids in having a stockier physique. Bears are omnivores, climb and swim well, run fast, and can stand and walk short distances on their hind legs. They have a short tail, long and thick fur, and excellent sense of smell and hearing. They hunt in the evening or at dawn. They are usually afraid of humans, but can be dangerous in places where they are accustomed to people, especially polar bear and a grizzly bear. Immune to bee stings. In nature natural enemies almost none.

Answer from Gulnara Abulkhanova[newbie]
Anatomically they are predators. Teeth, this and that. And constantly on plant foods he can not. But in last years In many regions, bears are increasingly using plant foods. In this regard, its numbers are growing; in some places there are significantly more of them than wolves. That is, he seems to be falling off the top of the food pyramid.

The bear family (Ursidae) includes the largest of modern land predators. Most taxonomists believe that there are currently eight species of bears on Earth (they are in turn divided into many different subspecies), belonging to three different branches.

Bears are found on all continents except Africa, Australia and Antarctica. Three species of bears - spectacled, sloth and Malayan - live in the tropics, but the center of origin of the bear family is in the Northern Hemisphere. A long time ago Brown bear also found in the Atlas Mountains of northwest Africa.

Bears are predominantly inhabitants various types forests and woodlands. One species - the polar bear - inhabits arctic deserts and ice.

The most likely ancestors of modern bears were small predators that lived 25 million years ago (subfamily Agriotheriinae). The oldest representative of this group, Ursavus elmensis, had long tail and looked like a raccoon, but animals of a later period already resembled modern bears both in size and in appearance. This group gave rise to three modern subfamilies. The giant panda was the first to separate from the common trunk, then the real bears (Ursus and its relatives) and spectacled bears (Tremarctos) separated.

Depending on the species, the body length of a predator can vary from 1 to 3 meters, the weight of individual polar and brown bears can reach up to 1000 kg. Males are much larger than females.

Bears have a heavy, awkward build. To support large mass, their hind limbs are plantigrade (when walking, the entire sole is pressed to the ground). This also allows them to rise and stand freely on their hind legs. The structure of the front paws is different different types bears - from plantigrade to semidigital (the back of the foot is partially raised above the ground). All species have five toes on each paw, equipped with curved, non-retractable claws.

The skull of bears is massive, larger than that of other predators; the facial section is of medium length or shortened (especially in spectacled bears). Wide molars with flat chewing surfaces and rounded fangs are well adapted for crushing and grinding plant foods. Polar bears are exclusively carnivores, which is why their teeth are sharper. Depending on the species, bears have 40-42 teeth.

Bears' fur is thick and long; The color is usually dark, monochromatic, from brown to black (as an exception, white or contrasting two-color), sometimes with a light pattern on the head and chest. The tail is very short; ears are small, round; the lips are large and very mobile.

Polar bears and most brown bears of the New World do not climb trees, only European browns and all other species climb trees where they feed or sleep, but they still prefer to spend most of their time on the ground. For tree-climbing predators, bears have amazing features - their tails are too short and their facial whiskers are completely absent.

Most species of bears are non-specialized omnivores that feed on berries, nuts, shoots, rhizomes and leaves of plants, as well as meat, fish and insects. They have an excellent sense of smell, color vision and good memory, which allows them to remember places rich in food. It should be noted that bears do not digest plant food very well, since their gastrointestinal tract does not contain symbiotic microorganisms capable of decomposing fiber (these bacteria are found in the stomach of ruminants). That's why vegetable fibers and the berries are excreted from the body almost undigested.

Photos and descriptions of modern bear species

Now let’s take a closer look at each of the eight species of bears.

Brown bear or common bear(Ursus arctos) – a typical representative of the bear family; found in Russia, Canada and Alaska. Prefers to live in old forest areas, avoids wide open spaces, but can live at altitudes of up to 5000 meters above sea level, where there are no longer forests. Habitats are usually confined to freshwater bodies of water.

The brown bear is a large animal: its body length is 1.5-2.8 m, its height at the shoulders is up to 1.5 m. Males weigh from 60 to 800 kg. The weight of adult predators varies depending on the time of year and geographic habitat. The smallest one is a pika eater from the mountains Central Asia, and the largest are Kodiak from Alaska and Kamchatka.

The photo shows a brown bear in all its glory.

Polar bear

Polar bear(Ursus maritimus) is the largest of the modern representatives of the family. Its body length is 2-2.5 m, height at the withers is about 1.5 m, body weight is on average 350–450 kg, but there are also giants with a body weight of more than 500 kg.

Distributed on the Arctic coast of the North Arctic Ocean, in Northern Canada.

The color of the fur is pure white, often yellowish due to contamination with fat, especially in summer. The fur is thick and warm, but the main warming function is played by a thick layer of subcutaneous fat.

The polar bear is the only member of the family that lives exclusively on a meat diet. He hunts young walruses, ringed seals, sea hares, beluga whales and narwhals.

On the picture polar bear with cubs. The female usually gives birth to two cubs once every 3 years. You can read more about polar bears in the article.

Black bear

The black bear or baribal (Ursus americanus) is found in Canada, Northern Mexico, the USA, except the central part of the Great Plains. Lives in dense forests, bushes, and also in more open areas.

Black bear sizes vary depending on geographical location and season. In the northern and eastern regions of its range, the baribal is larger. Their body length varies from 1.2 to 1.9 meters, height at the withers - from 0.7 to 1 meter.

The photo shows a black bear on a tree. The ability to climb trees is vital for baribals - here they feed and hide in case of danger.

The Himalayan or white-breasted bear (Ursus thibetanus) is found from Iran to South-East Asia, in Northern China, Primorye, Japan and Taiwan. Prefers to live in forests temperate zone, subtropics and tropics.

Body length is 1.2-1.9 meters, weight of males is 60-200 kg, females are 40-140 kg. Because of its long fur, the Himalayan bear appears much larger than it actually is. The coat is black with a white V-shaped mark on the chest, another mark is on the chin; There is a collar of long wool around the neck. Apparently, the collar plays a role in protection from predators, because this species has always coexisted next to the tiger.

The white-breasted bear is an excellent tree climber and often builds something resembling a nest by bending branches to the trunk.

The Himalayan bear is a rare, vulnerable species. For 3 thousand years now, people have been hunting it for its paws and gall bladder (dried bile is used in traditional Chinese medicine).

The life expectancy of the Himalayan bear is up to 25 years in the wild and up to 37 years in captivity.

Malayan bear

The Malayan bear or biruang (Helarctos malayanus) is the smallest species of bear, sometimes called the “dog bear”. Due to their small size and friendly disposition, Buriangs are often kept in captivity as pets in Asia. Their body length does not exceed 140 cm, they weigh 27-65 kilograms. Malayan bears have short, black fur with a white, orange, or dark yellow crescent-shaped chest marking.

Malayan bears are found in Southeast Asia and Eastern India. Their life is closely connected with trees, where they often sleep in specially built nests. They feed mainly on various fruits, but if such food is not enough, they switch to insects.

Malayan bears are diurnal. They breed at any time of the year, and the duration of pregnancy varies greatly (from 3 to 8 months).

In captivity, the Malayan bear can live up to 33 years.

The sloth bear (Melursus ursinus) lives in India, Nepal, Bhutan, and Sri Lanka. Found mainly in lowland forests and steppes.

Body length – 1.4-1.9 meters, weight – 80-190 kg. The sponge's coat is long, thick, black with a white spot on the chest. Its claws are slightly curved, its palate is wide, and its lips are elongated (this is how it got its name). These devices help the sloth fish dig up and suck up termites, which make up a significant part of its diet. And it received its generic name (Melursus) for special love to honey: he often climbs trees and is ready to endure bee stings just to feast on honeycombs. In addition to termites, other various insects and honey, the sloth fish eats berries with pleasure.

The sloth fish has long fur, which is quite surprising for a species living in the tropical forest. Apparently, it plays the same role as the loose clothing worn by people living in hot climates.

The sloth bear is a vulnerable species. In captivity, life expectancy is up to 34 years.

Spectacled bear (Tremarctos ornatus) Lives in the Andes from eastern Venezuela to the border of Bolivia and Argentina. Found in a wide variety of biotypes: mountainous and humid tropical forests, alpine meadows and even in deserts.

Body length – 1.3-2.0 meters, weight – 100-200 kg. The coat is black with a creamy white bib-like marking on the chin, neck, and chest; There are white markings of various shapes around the eyes (hence the name bear).

The spectacled bear is a rather slender animal. Despite its relatively large size, it is agile and climbs trees well, where it gets food and builds resting nests from branches and twigs.

In different habitats, the diet of spectacled bears varies, but everywhere food of plant origin predominates (fruits, bamboo, cacti, etc.). They also enter fields of grain crops and corn, which greatly annoys farmers.

In captivity, the spectacled bear lives up to 39 years.

Big panda

The giant panda or bamboo bear (Ailuropoda melanoleuca) is found in the Sichuan, Shanxi and Gansu provinces of central and western China. Prefers cool, damp bamboo forests at an altitude of 1500-3400 meters above sea level.

The height of a giant panda at the withers is 70-80 cm, weight is 100-150 kg. The fur of the bamboo bear is black and white (the circles around the eyes, the area around the nose, the front and back legs and shoulders are black, everything else is white).

The diet consists primarily of bamboo; occasionally pandas eat onions various plants, cereals, insects and rodents.

In the wild, a panda usually lives up to 20 years, in captivity - up to 30 years.

Today, enormous efforts have been made to preserve the giant panda, however, despite the most stringent ban, the animals still become victims of poachers. They also fall into traps set for other animals. Read more about the giant panda.

What types of bears are the most dangerous?

Bears are often spoken of as aggressive and dangerous animals. Indeed, their strength and size allow them to easily cope with a person, but the tendency of bears to attack people is greatly exaggerated.

Only polar bears, being true predators, are perhaps the only representatives of the family that actually sometimes perceive a person as prey, while tracking him down according to all the rules of hunting. Their attacks are caused by hunger, not fear. It is polar bears that are considered the most dangerous to humans. However, not many people live near polar bears, and people, knowing who they might have to deal with, always carry weapons with them.

Brown bears are in second place in terms of danger to humans, but their aggressiveness largely depends on geographical location a habitat. Grizzlies in the center of the American continent, as well as bears living in Siberia, are truly dangerous. This is especially true for mother bears who protect their cubs, or animals who defend their prey. More aggressive individuals are found in the eastern regions of Europe. But in general, all bears, like other wild animals, try not to get in the way of humans and, if possible, avoid meeting them.

American black bears, especially those that live near humans, often frighten people, but very rarely cause them any harm.

Spectacled bears are very cautious and are absolutely not aggressive towards humans, but it happens that they attack livestock.

Among Asian bears only big panda- a true vegetarian, and naturally does not pose any danger to humans.

Malayan bears are often scary local residents. If they are accidentally disturbed, they usually rear up, let out a furious roar and make a sharp lunge towards the enemy, but they rarely actually attack.

Himalayan bears and sloth bears, which often have to fight off large cats, are more likely to attack than to flee. Many people believe that sloth bears are more dangerous than tigers.

In contact with

The Bears are considered the largest predators currently living on our planet. Despite this, they are more likely than others carnivorous mammals, give preference to plant foods over animal meat.

Appearance of the bear

Teeth and claws: Bears' fangs are quite powerful, like those of other predatory animals. Molars have a flat, uneven surface that is easy to chew. This is due to a mixed diet; bears eat both animal and plant foods. Each paw has five long toes with large, sharp claws that do not retract. With the help of this tool, bears dig up edible roots and fruits from the ground. In addition, the predator uses its sharp claws to tear its prey into small pieces.

Sense organs: Bears have small eyes set close to each other. The fields of vision of both eyes overlap, so the animal sees objects in volume. In general, bears have poor eyesight. Hearing is also not very well developed. The bear has a better developed sense of smell. The bear will often stand on its hind legs and move its head to explore with its nose and gain information about its surroundings.

Communication: Bears communicate with each other using sounds and body movements. For example, the position of an animal's ears conveys information about the owner's mood. Having met, the bears raise their heads to each other and growl without opening their mouths. The bear's flat teeth can grind any food. A giant brown bear catches fish in the rivers.

Travel methods: Bears have fairly short limbs. They walk using the entire surface of their feet. Bears' paws are curved in the shape of the letter "O", so these animals have club feet and walk, waddling from side to side. But when danger arises or when chasing prey, bears are able to trot and even gallop. In case of danger, the bear stands on its hind legs. Cubs and adults of some species climb trees and swim, and the polar bear is the only mammal that swims using only its forelimbs.
Body Structure: Various They differ in size, but their structure is similar: a powerful body, short strong legs, a massive head and a very short tail.

Coat: Bear fur comes in several types, from the thick yellowish-white coat of the polar bear to the long, fluffy coat of the Sloth. The fur of most types of bears is brown in color and perfectly camouflages animals in the forest.

Did you know? What is the giant brown bear living in the territory North America, in other languages ​​called "Kodiak". This is the name of the island where these representatives of the subspecies are found. A bear standing on its hind legs can reach up to 3 m in height.
The polar bear can be found in the open sea at a distance of 80 km from the coast.
Bears walk slowly, waddling, but if necessary they can reach speeds of up to 50 km/h. The grizzly bear's menu consists of 80% plant foods.

The habitats of the polar bear and the arctic fox are located in the Far North. These are hardy mammals. Almost all bears are on the verge of extinction and are protected by law.
Once upon a time, there were many brown bears in Europe. Now their numbers have declined, but they still remain the most numerous species in the family. The polar bear was a subject of hunting in the past. People ate its meat and made clothes from its skin.
The polar bear has acclimatized better than other animals to the permafrost region.

Seven species of bears belonging to four genera live primarily in the Northern Hemisphere. Only the spectacled bear lives in the south. All bears, with the exception of the polar bear, which inhabits the snowy Arctic deserts, are inhabitants of dense forests. Their only enemy is man. Currently, only two species of bears are not threatened with extinction.

Origin of bears

The first bear, the ancestor of all modern species bears (Ursavus), who lived on Earth 20 million years ago. It was the size of a small dog and inhabited the area modern Europe, where at that time a hot subtropical climate, rich in lavish vegetation, prevailed. Bears, along with foxes, dogs and raccoons, descend from their common ancestor - small predator family Miacidae, who lived 30-40 million years ago and climbed trees. As a result of evolution, new species of bears arose, which gradually became larger, larger and stronger. Many, including the cave bear, which was larger in size than modern bears, became extinct. The youngest species in the family is the polar bear, which appeared 70,000 years ago.

1. Spectacled bear (Tremarctos ornatus): body length 1.3-1.8 m. The only representative of the family in South America.
2. Malayan bear (Helarctos malayanus): body length 1-1.4 m. This small member of the family lives in the tropical forests of Southeast Asia. Rarely seen.
3. Slothfish (Melursus ursinus): body length 1.4-1.8 m. Lives in the jungles of India and Sri Lanka. Herbivorous. It collects termites and insects with its lips and tongue.
4. Polar bear (Ursus maritimus): body length 1.8-3 m. Inhabits the northern regions of the Arctic, feeds mainly on seals.
5. Brown bear (Ursus arctos): 2-3 m long, lives in North America, Europe and Asia. There are several subspecies: grizzly bear, giant brown bear and European brown bear.
6. Baribal, black bear (Ursus americanus): body length 1.3-1.8 m, found in the forests of North America. Like other members of the family, it feeds on mixed food.
7. White-breasted bear (Ursus thibetanus): body length 1.4-2 m. Lives in forests and spends most of its time in trees. It feeds on herbs, fruits and berries.

Bear breeding

Bears live solitary lives, meeting only during the breeding season. The mating period, depending on the species, falls on different time of the year. Some species of bears, in particular the Malayan, can breed throughout the year - they live in tropical rainforests, where they have plenty of food. In addition, the Malayan bear is a monogamous species. After mating, the male and female separate. Only the she-bear is responsible for raising her offspring.

The duration of pregnancy is 180-250 days and depends on the type of bear. A bear litter consists of 1-4 cubs, which are born blind, toothless, and covered with sparse hair. They spend at least a year in the birth nest, feeding on their mother's milk. The polar bear never lacks food and therefore does not fall into winter sleep. However, pregnant females and mothers with cubs hibernate. In the spring, the she-bear leaves her den, accompanied by fluffy and playful cubs. The cubs follow her relentlessly, learning to find food and recognize danger. Bears of various species reach sexual maturity at the age of 2.5-5 years.

Lifestyle of bears

Bears are territorial animals. Each individual is the owner of a fairly large area, controls where it hunts and hibernates. Females live with their cubs for up to two years. Bears are avid loners, but in places rich in food, for example, in a berry meadow, several individuals can be found at once. Having had their fill, they disperse. But the bear has invaded someone else's territory and is awaiting a meeting with its owner, which could end in a clash. Searching for food takes a lot of time, so bears are active both day and night. Bears sleep in camouflaged shelters - dens, which are located in recesses under the roots of trees. A white-breasted bear makes a nest in a tree. Bears of the genus Ursus living in cold climatic zones, hibernate in winter. Winter dream lasts from 78 to 200 days. Exact time depends on the area. During hibernation, bears make a den for themselves among the windfall, under the roots of trees, or dig it on the slope of mountains and hills. They line and insulate their dens with grass, leaves and moss. Bears hibernate for a long time in order to survive the hungry winter period.

To the question: Are bears herbivores or predators asked by the author? Elena Yakshigulova the best answer is Bears are omnivores. They eat grass, berries, mushrooms, they will not refuse fish, especially meat, they put on fat - they eat everything until they are completely stupefied.
But pandas only eat bamboo, and polar bears prefer the fat of seals and seals.
