Animals that live in the Arctic are adapted to extreme conditions. Almost all of these animals have white skins. They not only help them hide in the snowdrifts white snow, but also give them incredible beauty and unusualness, unlike their counterparts who live in warmer climes.

polar Wolf(Canis lupus tundrorum) is a subspecies of wolf. Inhabits the entire Arctic, with the exception of ice floes and large areas covered with ice.
The polar wolf lives in vast areas of the polar regions, which are immersed in darkness for 5 months. To survive, the wolf has adapted to eat any food that comes across. It is well adapted to life in the Arctic: it can live for years at sub-zero temperatures, go months without seeing sunlight, and go weeks without food.
For centuries, people have mercilessly exterminated wolves of all varieties. However, the polar wolf is the only subspecies that still lives throughout the entire territory that was accessible to its ancestors. This happened because people rarely get here.

Arctic fox, the polar fox (lat. Alopex lagopus or lat. Vulpes lagopus) is a predatory mammal of the canine family, the only representative of the genus of arctic foxes (Alopex). The arctic fox lives in some of the coldest places on the planet. The Arctic fox is an incredibly hardy animal that can survive cold arctic temperatures down to -58°F (-50°c). It has fluffy fur and short ears to survive in such low temperatures. Arctic foxes live in burrows, and in a snowstorm they can dig a tunnel in the snow to create a shelter. Arctic foxes have beautiful white (sometimes blue-gray) coats that act as very effective winter camouflage. Natural shades allow the animal to blend into the ubiquitous snow of the tundra.






White Owl- the largest bird from the order of owls in the tundra. The head is round, the iris of the eyes is bright yellow. Females are larger than males. The body length of a male can reach 55-65 cm, weight - 2-2.5 kg, females, respectively, 70 cm and 3 kg. The wingspan averages 142-166 cm. The coloring is protective: adult birds are characterized by white plumage with dark transverse streaks. Females and young birds have more streaks than males. Chicks Brown. The beak is black, almost completely covered with feathers—bristles. The plumage of the legs is similar to wool and forms “braids.” Snowy owls play a key role in the tundra biota, being one of the main exterminators of rodents, as well as a factor in the successful nesting of some tundra birds. Using the extreme aggressiveness of snowy owls to protect the nesting territory, ducks, geese, geese, and waders nest on it. Owls do not touch birds, but they successfully drive away arctic foxes that destroy nests from their territory. It is listed in the Red Book.







It's a harsh winter outside, but not all the animals took refuge from it in cozy holes, falling into hibernation. In addition to the classic, well-known wolf, fox and hare fairy tales from childhood, in winter forests Representatives of the mustelid family are awake. The smallest mustelid is an animal called. The weasel received such an apt description as “a thunderstorm of mice.” This animal is the only mustelid that has no commercial significance due to its small size. With a length of 20 centimeters, 4.5 cm is accounted for by a short tail. Like a ferret, the weasel is a rather smelly animal. First you smell it, then you see it. In winter, the weasel is completely white, the color of snow, and in summer it is white and brown. Moreover, the edge of the upper lip, the entire lower side of the body and the inner sides of the paws remain white. The weasel is primarily a nocturnal animal, but where it sees no danger for itself, it can hunt during the day. Among the mammals, the animal's prey consists of house mice, field mice, and forest mice. Of the birds, the weasel feasts on larks and other birds living on the ground, as well as pigeons and chickens, if it gets into the chicken coop. She does not disdain lizards, frogs, fish and snakes. It can attack a viper, although the bite of this weasel snake is fatal. All kinds of insects are a delicacy for her, and she can even cope with the hard shell of a crayfish when she comes across one on occasion. The weasel runs, jumps, swims and climbs trees well. Its ability to crawl through the narrowest cracks and holes is its main strength. Thus, the weasel easily chases mice into their own burrows. The weasel grabs small animals by the back of the head or the head, and tries to grab onto the neck of large animals. She skillfully makes one or several holes in bird eggs and sucks out their contents without losing a single drop.




Arctic hare(lat. Lepus arcticus) is a hare, mainly adapted to living in polar and mountainous areas. Previously it was considered a subspecies of the mountain hare, but is now recognized as a separate species.




Snow leopard.


Polar bear, oshkuy (lat. Ursus maritimus) is a predatory mammal of the bear family. Sometimes this species is classified as a separate genus Thalarctos. Latin name Ursus maritimus is translated as “sea bear.” The polar bear is the largest terrestrial representative of mammals of the order of carnivores. Its length reaches 3 m, weight up to 800 kg. Males usually weigh 400-450 kg; body length 200-250 cm, height at the withers up to 130-150 cm. Females are noticeably smaller (200-300 kg). The smallest bears are found in Spitsbergen, the largest in the Bering Sea. The polar bear is distinguished from other bears by its long neck and flat head. His skin is black. The color of the fur coat varies from white to yellowish; In summer, the fur may turn yellow due to constant exposure to sunlight. Wool polar bear lacks pigment color, and the hairs are hollow. There is a hypothesis that they act as light guides, absorbing ultraviolet rays; in any case, in ultraviolet photography the polar bear appears dark. Due to the structure of the hairs, a polar bear can sometimes turn green. This happens in hot climates (in zoos), when microscopic algae grow inside the hairs.








harp seal, or coot (lat. Phoca groenlandica, lat. Pagophilus groenlandicus) is a common species of true seals (Phocidae) in the Arctic. A pronounced inhabitant of cold waters, but avoids the Arctic pack, preferring drifting ice. Makes holes in the ice. Makes wide seasonal migrations. During the periods of breeding and molting, it rests on ice. Not a strict monogamist. Harp seals live in herds, the age and sex composition of which varies throughout the year. There are fights between males during the mating period. Pupping occurs in strictly localized areas (<детных>ice). In communication, acoustic and visual signals are of primary importance. It feeds on pelagic invertebrates and fish. Mating occurs in March. Pupping was noted at the end of February - beginning of March. Pregnancy is 11.5 months; there is a long latent stage in the development of the embryo. Usually 1 cub is born, covered with thick, long white fur (squirrel) with a greenish tint (the tint disappears a few days after birth). The weight of the newborn is 7-8 kg. After a week, the squirrel begins to molt (Khokhlushi stage); a completely moulted baby is called a serok. Reaches sexual maturity at 4.5 years.

Reindeer - Rangifer tarandus. The reindeer has an elongated, squat body (length 180-220 cm, height at the withers 100-140 cm). There is a short, not always noticeable mane on the neck, and an elongated muzzle. The color is brown in summer, gray in winter, lighter in tundra deer. The mane is white in winter. Small fawns are single-colored, only in Southern Siberia do they have white spots along the back. Both males and females have horns. They are very long, thin, crescent-shaped; the lateral processes are located on the outer (back) side of the trunk, and not on the inner (front), as in real deer.
At the ends of the antlers, and often in front of their base, there are small triangular shovels with processes. Domestic deer are difficult to distinguish from wild ones, but in their herds there are much more white and spotted animals. In addition, they have almost no fear of humans, while wild deer (sokjoi) are usually very cautious. The eyes of a reindeer glow with a dim yellowish light at night. When reindeer move, a peculiar clicking sound is heard, by which you can recognize the approach of a herd at night from hundreds of meters away.

The Arctic is the region located around the North Pole. There are polar days and nights, winters are very cold, and summer temperatures do not rise above zero degrees. But for many creatures, such extreme conditions are only a plus. What animals live in the Arctic. We offer you descriptions and photographs of the most interesting animals of the Arctic.

Carnivorous mammals of the Arctic

Most Arctic predators are ferocious hunters with voracious appetites that can attack livestock and even humans. The number of individuals in the population of Arctic predators depends primarily on the number of lemmings, which are the main “delicacy” for arctic foxes, wolverines, polar wolves, and in some cases reindeer.

1. Polar bear

The largest representative of the Bear family, listed in the Red Book of the World back in 1953, is not found anywhere except the Arctic. To live, he needs clearings of drifting ice, ice holes or the edge of ice fields, and seals - his favorite food.

The closest recorded habitat of polar bears to the pole has a latitude of 88°15". Some male polar bears reach three meters in height and a ton of weight. But with such impressive size and apparent clumsiness, polar bears are extremely active and hardy animals.

Polar bears are excellent swimmers, covering up to 80 km in icy waters, thanks to the membrane on their paw pads. Polar bears easily travel about 40 km per day, coping with difficult ice ridges and deep snow. Polar bear fur retains heat so well that even aerial infrared imaging cannot detect it.

2. Wolverine

A large representative of the Mustelidae family, a ferocious predator and an extremely voracious animal. Due to the ability of this animal to attack livestock and even people, it is also called the Demon of the North. The weight of wolverines varies from 9 to 30 kg, and in appearance they are more similar to badgers or bears.

Unlike other representatives of the Mustelidae family, the wolverine migrates within its individual territory, constantly searching for food. The animal easily climbs trees thanks to its sharp claws and powerful paws. It makes sounds similar to the yelps of dogs and has excellent hearing, vision and sense of smell.

The wolverine is omnivorous, it can both eat leftover food from other predators and hunt on its own even quite large animals; it also eats plants - berries, nuts. This is such a brave and vicious animal that even the owner of the Arctic, the Polar Bear, tries to avoid it when meeting it.

3. Arctic wolf

This subspecies of wolf lives throughout the tundra and Arctic. It usually feeds on small animals - arctic hares and lemmings, but musk ox and reindeer are also part of its diet. In the harsh conditions of polar nights and long cold periods, he adapted to feeding on any food.

Polar wolves can only survive in a pack. In the Arctic deserts, where there is no room for an ambush, they have to resort to another - social hunting tactics, often patiently waiting for the victims to make a mistake and weaken their defenses.

4. Arctic fox, or polar fox

The polar or arctic fox is a predatory animal, the only representative of the Arctic fox genus. Unlike the common fox, it has a shortened muzzle, small rounded ears, paws covered with coarse hair and a squat body. Depending on the season, the fur of the Arctic fox can be white, blue, brown, dark gray, light coffee or sand. Based on this characteristic, 10 subspecies of animals are distinguished that live in different territories.

No further than half a kilometer from the water, the arctic fox digs complex burrows with numerous entrances. But in winter period he often has to make do with a den in the snow. He eats everything; his diet includes both plants and animals. But the basis of its diet are birds and lemmings.

Ungulate mammals of the Arctic

The plant populations of the Arctic provide for the existence of large groups of large herbivorous ungulates. Their numbers are subject to strong changes due to long cold periods. An adaptation to this is their migration to forest areas located to the south.

1. Reindeer

Animals evolve the faster the more complex the conditions of their existence. Reindeer are so different from other representatives of the Olenev family that it immediately becomes clear that they are okay with difficulties. Caribou (as they are called in North America) are not only champions of survival, but also the youngest members of the family. They appeared only about two million years ago.

The flat and wide hooves of reindeer, pointed at the edges, turn the animals into all-terrain vehicles. They travel through snow, swamps and ice with ease. These same hooves, used instead of flippers, help deer to swim perfectly and overcome not only large rivers such as the Yenisei, but also sea straits. Their fur has a special structure; its hairs expand towards the end and create a heat-insulating air layer. Even their upper lip and nose are covered with delicate, soft hair.

Reindeer eat a variety of food - in summer it is succulent plants, in winter - lichens and shrubs. To compensate for the lack of microelements, they gnaw on their own discarded antlers and eat algae and shells washed ashore. An important reason for their survival is their herd lifestyle.

2. Muskox

A rare powerful hoofed animal, the same age as the mammoth, with a thick undercoat that is several times warmer than that of a lamb. Their long, thick hair hangs from above almost to the ground and covers the animal, leaving only the hooves, horns, nose and lips outside. Musk oxen survive the winter cold without migrating and easily tolerate very coldy, but die in the presence of high snow cover, especially with an ice crust on top.

Pinniped mammals of the Arctic

Their nostrils are large enough to allow them to inhale enough air to stay underwater for up to 10 minutes. Their forelimbs are transformed into flippers, and their food is marine life - mollusks, krill, fish, crustaceans. Let's introduce the most common pinnipeds of the Arctic.

1. Walrus

The only modern representative of the Walrus family is easily distinguishable thanks to its massive tusks. In terms of size, it ranks second among pinnipeds after the elephant seal, but the ranges of these animals do not overlap. Walruses live in herds and bravely protect each other from enemies.

2. Seal

They have a wider distribution and live along the shores of the Pacific, Atlantic and Arctic oceans. They are very good swimmers, although they cannot be found far from the shore. Seals don't freeze in cold water thanks to a thick layer of subcutaneous fat and waterproof fur.

3. Navy SEAL

Fur seals, together with sea lions, belong to the family of eared seals. When moving, seals rely on all their limbs, and their eyes have a dark outline. In summer, the Northern fur seal lives in the north Pacific Ocean, and with the arrival of autumn it migrates south.

4. Northern elephant seal

It should be noted here that elephant seals are divided into northern (living in the Arctic) and southern (living in the Antarctic). Elephant seals got their name because of the impressive size and trunk-like nose of old males. They live on the Arctic coast of North America and even further south. Adult males reach a mass of 3.5 tons.

Marine mammals of the Arctic

No other mammal has the ability to survive the harsh conditions of the Arctic with cetaceans such as the beluga whale, narwhal and bowhead whale. They do not have the dorsal fin present in other cetaceans. The Arctic is home to about 10 species of marine mammals - whales (fin whales, blue whales, humpbacks and sperm whales) and dolphins (killer whales). Let's talk about the most popular of them.

1. Narwhal

They are distinguished by the presence of only two upper teeth, of which the left one in males develops into a tusk up to 3 meters long and weighing up to 10 kg. With this tusk, males break the ice, making holes; it also serves to attract females and many other purposes.

2. Belukha

This is a species of toothed whale from the Narwhal family. Beluga whales also require atmospheric oxygen and risk suffocation if trapped under solid ice for long periods of time. They feed on fish and make a variety of sounds.

3. Bowhead whale

This is the only representative of baleen whales that lives its entire life within the cold waters of the Northern Hemisphere. In the spring they migrate north, and in the fall they sail a little south, avoiding the ice. They feed on plankton.

4. Orca (killer whale)

The killer whale is the largest predatory dolphin. Its coloring is contrasting - black and white with distinctive white spots above the eyes. Another original feature of killer whales is their tall, sickle-shaped dorsal fin. Different populations of these predators specialize in certain food. Some killer whales prefer herring and migrate after their schools, others hunt pinnipeds. They have no rivals and are the top of the food chain.

Rodents of the Arctic

It is impossible to overestimate the importance of lemmings for the existence of animals in the Arctic deserts. Almost all of the above-mentioned land animals feed on them. And polar owls don't even nest if the lemming population is not in the best condition.

Animals of the Arctic listed in the Red Book

Currently, some Arctic animals are endangered. Natural and human-induced changes in the climatic conditions of the Arctic pose a significant threat to the animal world. The list of Arctic animals included in the Red Book includes the following representatives of the Arctic zone.

• Polar bear.
• Bowhead whale.
• Narwhal.
• Reindeer.
• Atlantic and Laptev walruses.

TO rare species animals also include the musk ox. His ancestors lived on Earth back in the days of mammoths.

In June 2009, by order of the Russian government, it was created national park“Russian Arctic”, the main task of which is to preserve and study representatives of the flora and fauna of the Arctic, which are on the verge of complete extinction.

Animals of the Arctic do not live at the North Pole itself; it is impossible to live there. They are more often found in the southern regions of the Arctic Ocean, on the coasts of continents and on islands.

Usually, when talking about the fauna of the Arctic, birds are not the first thing that comes to mind. And yet it is the birds that give the white silence of this region a special charm. The ringing song of the polar sparrow - snow buntings Plectrophenax nivalis represents the arrival of real spring in the Arctic.

Its appearance at polar stations is the same as the arrival of rooks and starlings in the villages of central Russia. The black-and-white bird is perhaps the only representative of song passerine birds in the polar regions. This tiny traveler was carried by evil winds to the North Pole. Usually the bunting feeds on plant seeds, but it needs to feed its small chicks on insects. Where can you get them in the Arctic? Of course, there are several types of mosquitoes here. There are even those who are unable to fly due to undeveloped wings. There are very, very many of them... but only on warm days. Buntings have to make a lot of effort to feed their offspring to the full even during cold weather - for example, by collecting free-living nematodes in the snowfield.

On the Arctic islands, even far from the mainland, no, no, and you will meet a brood in the summer tundra partridge Lagopus mutus. It seems that these birds, typical inhabitants of the mountain tundra, do not belong here. But the sparse vegetation, crushed by frost and harsh winds, turns out to be quite sufficient for the existence of these representatives of the gallinaceae. They cannot survive here in winter. It’s hard to imagine how much effort it takes for these birds to reach the mainland.

And yet, mainly the feathered kingdom of the Arctic thrives at the expense of the sea. The vast majority of northern birds are its typical inhabitants. On land they appear only for nesting and raising chicks. The location of bird nesting sites is determined here mainly by the availability of safe nesting sites and available food resources. When choosing a breeding area, the last factor is decisive. For birds that have close food connections with marine ecosystems, nesting areas are confined to marine areas with increased biological productivity - for example, to frontal zones or marginal zones of drifting ice. At the same time, many species of birds are so adapted to the marine environment, to the aquatic lifestyle and to diving to great depths that they feel insecure on land and are forced, even during the breeding season, to obtain absolutely all the food for their chicks in the sea.

Typically marine species birds use all food sources available to them in the sea, developing specific adaptations that facilitate their prey. They can be planktivores, ichthyophages and feed on benthos. Omnivores are also found among seabirds.

Representatives of petrels - fulmars Fulmarus glacialis - with the help of long narrow wings, they soar for a long time in air currents above the sea surface. In flight, they search for large accumulations of zooplankton, simultaneously using other objects for food, including fishing waste. With their beak and upper beak, armed with a curved sharp hook, they are capable of tearing the skin of dead animals found in the sea.

A light color variant of the fulmar. Narrow long wings make it easier for the fulmar to fly in air currents, but make it difficult to land and take off from the water in calm weather.

In exceptional cases, fulmars can also attack small species of gulls, such as the kittiwake Rissa tridactyla, tearing out pieces of muscle from living birds with their beaks.

When a source of food becomes available to fulmars, they accumulate in a given area of ​​the water area. back side colonial lifestyle - increased aggressiveness towards their neighbors.

In the water column they hunt for small fish auk birds. Due to their short and narrow wings, they are not distinguished by any virtuoso flight in the air - although they fly quickly, they are not able to maneuver. But their wings, when bent, allow them to fly underwater and effectively pursue prey in the water column. In the Arctic seas, the most numerous species of auk birds is thick-billed guillemot Uria lomvia. On land, guillemots move with difficulty; their webbed paws are not adapted for this, but in the air and during underwater flight they act as rudders. And one more thing: the webs of the paws, pierced with blood vessels, serve as an excellent heating element when incubating eggs.

The structure of the wings allows the guillemot to dive excellently, but when trying to land on its own piece of rock, it experiences difficulties. It often misses, especially in calm weather.

Guillemots choose breeding sites on rocks inaccessible (or almost inaccessible) to four-legged predators, where the bird lays a single pear-shaped egg.

During the entire incubation period, guillemots hold it on their paws, covering it from above with their body, in the plumage of which during this period a bare patch of skin appears - the brood spot. These birds do not build nests, but when changing partners, they roll the egg from paw to paw. And only if the incubating parent is frightened can the egg end up on a rock, often covered with ice. Guillemots often nest on sloping rocky areas, where such transfer from paws to paws is the only way to preserve the egg.

Guillemots try to nest side by side, but even among them there can be individualists.

It is noteworthy that the eggs do not have camouflage coloring. In the presence of various spots, specks and “squiggles”, the general background color can be white, bright green or dull bluish shades. The constant presence of one parent reduces the importance of egg coloration for protection from predators. Guillemots are obligate colonial birds; they can nest and reproduce normally only in colonies, that is, in clusters of birds of their own species. For normal reproduction, they need to hear calls (acoustic background) and see (visual background) birds of their species. This is probably why the booming cries of guillemots can be heard far across the surrounding area. This method of nesting in dense colonies reduces the possibility of death of offspring from the activities of feathered predators, which in high latitudes include, primarily, large gulls. During rockfalls, landslides, and unsuccessful flights, guillemots are often injured and even die. Arctic foxes hunt them near the colonies.

It is generally believed that the pear-shaped shape of the egg is associated with the nesting of birds on rocks and prevents the eggs from rolling off in the event of birds flying off. This is not entirely true. Anyone who has worked in guillemot colonies is well aware that when birds fly away due to a sudden fright (collapse of a rock, sound signal from a ship, etc.), a massive fall of eggs from the rocks is observed. When pushed, a freely lying egg still moves in a gentle arc. The pear-shaped shape of the egg in this case does not help the birds at all.

During the period of mass egg laying, guillemots climb to the edges of the colonies and steal them. Some of the eggs are hidden for future use.

But this form is optimal for this method of incubation, when the egg is on the bird’s feet. Special experiments have shown that in areas densely populated by guillemots, birds are able to recognize an egg that has moved in an arc within a diameter of 50-70 cm as their own. The birds cannot recognize an egg that has rolled out beyond these limits as their own and throw it away. Successful breeding seasons for guillemots do not happen every year. Feathered chicks, not yet capable of flight, leave the colony by jumping into the sea, often from a great height. The underdeveloped flight feathers of the wing, with frequent flapping, allow them to soften the blow to the water, where they are met by an invitingly screaming male. From the moment the fledgling splashes down, he takes full care of it. But in cold years, when the sea around the colonies is clogged with ice, the chicks may not reach open water. During these seasons it happens mass death offspring.

The chicks are landing on the waterincapable of fieldthat. In cold seasons, to get to open water, they have to make a long trek across ice fields. In this dangerous enterprise they are accompanied and protected by the male.

In Arctic latitudes, the main food of thick-billed guillemots is pelagic fish (most often polar cod) and small crustaceans. In pursuit of food, guillemots are capable of diving to great depths, significantly exceeding one hundred meters. But most often they find accumulations of available food in shallower layers of water. It is still not clear how guillemots identify prey in the absence of light at great depths or in surface waters during the polar night. Studies of the structure of the guillemot's eyes have shown that they are not adapted for night vision. Concerns are often expressed that, as the Arctic warms, the food supply of guillemots will change so much that this will lead to the degradation of their colonies. However, so far in colonies where the number of birds is controlled, in recent years there has been no decrease in nesting guillemots; on the contrary, in some colonies it is increasing. Due to methodological difficulties, it is very difficult to estimate the total number of thick-billed guillemots living in the Arctic, but it is clear that at present it may amount to several million individuals.

Broods of guillemots gather to rest even in small areas of water, allowing them to get a short respite from attacks by predators.

Along with thick-billed guillemots, another widespread species of auk birds lives in the Arctic - little auk Alle alle. It is a specialized consumer of zooplankton. Small black and white birds, weighing only 200-250 g, inhabit rocky screes like fairy-tale gnomes. There, in the crevices, among the stones, they set up a primitive nesting chamber, where, in the absence of any lining, their only bluish egg is located.

Little auk colony on the island. Hooker of Franz Josef Land.

In such nesting conditions, neighbors do not see each other, so they regularly hold mass gatherings on the highest talus stones. Such places are usually called “clubs”.

The little auk is a colonial species of bird and feels normal only in the company of its own kind.

Another method of communication that little auks resort to is constant vocalization. The birds continuously emit piercing trills, which make it quite easy to detect their colony. The social activity of little auks is uniquely manifested in specific circular flights - “carousels”. There is an assumption that in this way, at the very beginning of the season, the birds synchronize the reproduction of individual pairs in the colony, and young individuals visiting this scree for the first time select a place for future nesting and get to know their neighbors.

The closed nesting method and the extremely high social activity of birds cause significant difficulties in counting birds in colonies. As a result, the number of little auks in settlements is determined with rough tolerances during regular counts of individuals in “carousels” and in colonies. The total number of little auks in the Arctic can be estimated at several million individuals.

Little auks swim and dive well, catching dense accumulations of the pelagic crustacean Calanus. It is saturated with fat and is a high-calorie food. But the calanus is very small, and little auks are forced to catch it until the sublingual sac is completely filled. They do not have special devices (straining and filtering) for mass catching of crustaceans. The birds probably stuff their sublingual sac with prey, grabbing the crustaceans one at a time. It follows that this method of hunting can only be effective in very dense concentrations of prey.

The little auk brings the caught crustaceans to the chicks in the sublingual pouch. With the help of such outgrowths on the palate, it holds the Calanus crustaceans when caught.

Little auks are a real decoration of the Arctic, enlivening its coastal areas with their polyphony. After the chicks land on the water, which will also be accompanied by males until they fly, the colonies quickly become empty, and silence hangs over the rocky scree.

Another representative of the Chistikov family, in fact, who gave him the name - that’s what he’s called guillemot Cepphus grille. Unlike guillemots and little auks, guillemots do not nest in large colonies. Their sparse settlements usually consist of several pairs and very rarely reach several dozen individuals. Birds lead a secretive lifestyle. In the first half of summer, their presence can be recognized only by manifestations of social activity on the water in quiet evenings and nights. Guillemots gather in groups and demonstrate elements of mating behavior. They make their nests in cracks and crevices of rocks along the edges of bird colonies, less often in rocky screes.

As a rule, guillemots lay two eggs. The hatched chicks are fed with small bottom fish, crustaceans and polychaetes. Fully fledged young guillemots, left behind by adults, go to the water and immediately begin to lead an independent lifestyle.

One of the classic representatives of the Arctic avifauna and important formative elements of bird colonies is the small gull. kittiwake. It is often called the three-toed gull (only three fingers are fully developed) and the black-footed gull. But in Russian ornithology, its Pomeranian name – kittiwake – has taken root. She got it on the Murmansk coast of the Kola Peninsula, where in a food sense it is closely related to capelin. The population of Murman, who actively collected bird eggs, noticed a characteristic feature: during capelin harvest years, kittiwakes nest in bird colonies in large numbers, and in their nests there are often clutches of two or three olive-brown eggs.

In Arctic regions Barents Sea capelin appears infrequently, and kittiwakes obtain other food there. But it is extremely rare to see a complete clutch of three eggs in kittiwakes in these areas. Usually it is one or two eggs here. The average clutch size of kittiwakes is an excellent indicator of the birds' food supply during the pre-breeding period. In seasons when the availability of food for kittiwakes is severely limited, the phenomenon of non-nesting is observed. In this case, most of the kittiwakes occupy the colony, often even restoring nests, but do not begin laying eggs.

The kittiwake is also an obligate-colonial species and can reproduce normally only in groups with a minimum of 10-20 pairs of its species. It was not for nothing that they called her the talker. In the colony, the birds lead an active lifestyle, constantly screaming and conflicting with their neighbors.

In the colony, kittiwakes are characterized by demonstrative behavior, which often immediately turns into scandals between neighboring pairs.

At the same time, these scandals and demonstrative behavior in the colonies have their own biological meaning. This activity helps to synchronize the reproduction of birds in the colony. The birds make their nests on the ledges of steep rocks, using remnants of vegetation, moss and mud as building materials. The birds incubate the clutch one at a time and sit very tightly. In Arctic regions, where the feeding capabilities of birds are limited (birds fish only the surface layer of the sea), distinct differences in the foraging behavior of the sexes are observed. Males make long search flights. Their prey is often small fish, mainly cod. Females leave the nests for a shorter period of time. Most often, they feed near glaciers and nearby ice fields, where zooplankton immobilizes and accumulates at the junctions of fresh melt water and salty sea water. This is what female kittiwakes most often feed on.

At the junction of sea water and fresh runoff from melting glaciers, immobilized zooplankton accumulates, which kittiwakes constantly feed on.

It is clear that in cold seasons, when the spaces around the colonies are filled with ice, kittiwakes have to spend much more time foraging for food. The chicks get much less of it, and the phenomenon of socially determined mortality appears in the colonies. Chicks fight for access to food, and, as a rule, the strongest and most aggressive chick wins. Fully feathered kittiwake chicks gradually leave their native colonies and form flocks consisting almost exclusively of young birds. A warming Arctic will likely provide kittiwakes with more abundant, high-calorie food, and their numbers in the region will increase. Currently, in the Russian sector of the Arctic, the number of kittiwakes can reach a million individuals.

A young kittiwake has just left its parent's nest.

But the real symbol of the Arctic is still another seagull – white Pagophila eburnea. Of all seabird species, it is the one most closely associated with ice. The breeding area of ​​the ivory gull is located within homogeneous ice areas and is limited by the ice regime and seasonal ice conditions of the sea. The determining factor for choosing a nesting site for an ivory gull is the absence of four-legged predators – arctic foxes. For breeding, it prefers coastal tundras, low-lying areas of islands near glaciers or sea ice.

The whole life of seagulls is connected with arctic ice, they even form colonies near glaciers.

Unlike kittiwakes, the ivory gull is a facultative-colonial species of seabird. In fact, it can reproduce normally both in colonies of its species and in separate pairs. Existence in the harsh conditions of the Arctic has left its mark on ivory gulls. They are characterized by high interannual fluctuations in the number of nesting birds, the abandonment of colonies and the formation of new ones during one season, and a radical change in nesting sites. In favorable years, early breeding periods, a high density of nesting birds and the presence of clutches of three eggs are noted.

The white gull is an omnivorous species. Among the ice in the sea, she catches cod and crustaceans. Actively feeds on the corpses of animals, picking up leftover food and their excrement. Often these birds visit landfills near residential settlements, looking for food waste. Cases of cannibalism are also typical for them.

During the research of the Russian scientist M.V. Gavrilo in last years in the Russian sector of the Arctic, the number of ivory gulls was determined to be 11-13 thousand pairs. It was not possible to identify any pronounced trends in the development of the Russian population. But it is known that there are very real threats to this species, primarily organochlorine pollution. Ivory gulls have one of the highest levels of these chemical compounds among Arctic birds. One of the possible threats to ivory gulls may be the warming factor in the Arctic regions. For these reasons, the species is included in the Red Book of the Russian Federation and the Red List of the International Union for Conservation of Nature.

White gull chick at the nest

Larus hyperboreus – this species of gull is one of the largest seabirds in the Arctic. Distributed circumpolarly. The glaucous glaucous is a facultative colonial species of seabird. Breeds in single pairs and sparse settlements. Prefers to choose nesting sites near colonies of other bird species or at river mouths. Large colonies, up to a hundred pairs or more, are rarely formed, as a rule, only in areas rich in available food.

The glaucous glaucous is omnivorous. In the sea among the ice it catches cod and crustaceans. Uses dead animals, industrial waste, and food waste near residential premises for food. In bird colonies, it actively destroys nests and steals chicks.

The burgomaster who stole an egg from a guillemot. He can swallow such an egg whole.

If necessary, the glaucous guillemot is capable of catching adult guillemots, kittiwakes and guillemots. Cases of cannibalism are typical for the burgomaster. In Arctic seabird colonies it is the main feathered predator.

The glaucous guillemot is capable of catching an adult kittiwake and even a guillemot. But more often it uses injured and dead birds for food. A pair of glaucous guillemots near a dead thick-billed guillemot.

It builds massive nests from plant remains on the coasts on the tops of large stones, in bird colonies along the periphery of the colonies. A complete clutch consists of three olive-brown eggs with dark spots. Nests are actively protected from terrestrial predators.

During a vertical dive, it can hit the violator of the boundaries of the nesting area (Arctic fox, human, etc.) with its paws. The chicks are successfully fed with any food available in the nesting area.

The burgomaster had a hearty lunch.

In many areas of the Arctic, during the breeding season, you can find seabirds with a unique way of life - short-tailed skua Stercorarius parasiticus. This close relative of gull birds, a prominent representative of the Skua family, is distributed circumpolarly in the Arctic regions. Using masterly maneuverable flight, the skua has adapted to catch small birds and take food from other birds. At the beginning of the 20th century, the Pomors called him “robber”, “fomka”, “police officer”. These names reflected the thieving and predatory nature of the bird's behavior.

The Short-tailed Skua nests in low-lying areas of coastal tundra, most often in solitary pairs. Spends a lot of time in the air, playing catch-up games. Flights are accompanied by characteristic screams, vaguely reminiscent of the screams of cats. Each pair occupies a certain territory, which it actively defends both from third-party birds of its own species and from other border violators, including humans.

The skua actively defends the nesting territory from enemies, often striking the intruder with its paws.

When a predator appears, it either attacks, striking with its paws in a dive, or actively imitates a wounded animal, accompanying its demonstrative behavior with a “chick’s” squeak.

The nest is an unremarkable hole in the ground without any lining. A complete clutch consists of two olive-brown eggs. As easy as it is to spot skuas themselves in the area of ​​their site, it is just as difficult to spot their nest or hidden chick in the area.

It is problematic to estimate the actual number of short-tailed skuas in Arctic regions. It is unlikely that it exceeds several tens of thousands of breeding pairs. There are currently no significant threats to populations of Short-tailed Skuas.

Among Arctic birds, few species contain the term “polar” in their names. These include Arctic tern Sterna paradisaea. In the Arctic zone, the Arctic tern has a circumpolar distribution. Of all the terns, this is the most northern species. The appearance of the Arctic tern is memorable - a small white-gray bird with a dark cap, scarlet beak and legs, characteristic sharp wings and a “swallow” tail. Like all colonial birds, it is “talkative”. The species-specific cry of the Arctic tern, “Kirrya-ya-ya,” can be constantly heard over its nesting area. Actively protects its offspring, striking with its sharp beak when attacking.

Breeds in low-lying areas. The nest is an ordinary hole. The maximum clutch size is three eggs. Sometimes clutches with four and five eggs are found, but in these cases they may well be double clutches.

The Arctic Tern feeds on small objects: small fish and various forms of zooplankton. Looks out for prey in the water column, hovering over it with characteristic fluttering wing beats. Having discovered prey, it tries to catch it during a “shock dive.”

Arctic terns catch fish and small crustaceans. After a hasty dash, the tern flies away with an amphipod in its beak.

The hunting method raises the question of whether Arctic terns have polarized vision (this is the ability to see objects in the water at different lighting angles, despite glare and reflections) and the need for sufficient illumination of the feeding area. It leaves the nesting areas in early August, perhaps the first of the entire complex of Arctic birds. In mid-August, birds appear in the vast North Atlantic. The Arctic tern gained public fame due to the length of its routes and the remoteness of its wintering areas. Arctic terns spend the winter in Antarctic waters. The average length of their migration routes during one annual cycle, according to Russian researcher A.E. Volkov, amounted to more than 84 thousand km, and the duration of wintering in the Antarctic regions was more than 120 days.

Downy Arctic Tern chick

Among the seabirds of the Arctic, there is also a famous species of sea duck – Somateria mollissima. Distribution is circumpolar. The large sea duck (weighing about two kg) has pronounced sexual dimorphism.

A male eider in a contrasting, revealing plumage.

The common eider is an excellent diver, although it does not demonstrate records for diving depth. Its usual “working” depth is within ten meters. When diving, it actively uses its wings, demonstrating “underwater flight”, but having reached, when moving in the water column, it uses only webbed feet. With the help of its powerful beak, it captures available benthic organisms, literally tearing them out of the ground. Among the objects caught, the most common are mollusks, crustaceans, starfish and urchins. Whenever possible, eiders also catch fish. If in the southern regions of the Barents Sea mollusks play a leading role in the composition of feed, then in the high-latitude regions of the range the importance of crustaceans sharply increases.

The common eider usually nests on islands where there are no land-based predators. The number of eggs in a clutch may vary, but in the northern regions of the range there are usually 3-4. The female incubates the clutch.

The female common eider in her brown plumage clearly appears on the ice before nesting. But it will be difficult to detect when incubating the clutch.

Rarely leaves the nest, only to get drunk. During the incubation period, she does not feed. The eider's nest is lined with , which in the last century was considered as an unsurpassed insulation material. With the development of chemical analogues, its importance has noticeably decreased, and products made from eider down from the “working” category gradually migrated to the “status” category.

No amount of fluff can save a clutch from a polar bear. When he appears, the eiders fly to the water, and everything that the bear does not eat is eaten by the glaucous gulls.

The current state of eider nesting sites in the Russian sector of the Arctic is unclear. In recent years, the southern regions of the Barents Sea and the islands of the Franz Josef Land archipelago have been explored to a greater extent. At the same time, nothing is known about the number and condition of the common eider nesting sites on Novaya Zemlya. The total world population is about 3-4 million individuals. Among the threats to the common eider, a factor of concern during the further development of the Arctic zone can be considered as a very real one; for individual populations and breeding groups, oil pollution of the water area can be considered. Possible warming in the Arctic regions does not pose a serious threat to the populations of the common eider. The adaptive potential of the species is quite high, as demonstrated by the history of the establishment of the common eider in the Black Sea.

Once upon a time, products made from eider down were classified as “working” among residents of the North and polar explorers. Now they tend to be viewed as “status” things. Most eider breeding sites are included in the composition, where any economic activity is strictly regulated. In other areas of the northern seas, searching for eider nests is labor-intensive and, subject to all bird protection measures, does not justify the costs.

Outside the breeding season, during seasonal migrations and wintering, most species of colonial seabirds adhere to water areas with high biological productivity, confined to various frontal zones in the North Atlantic and North Pacific. Some seabird species are closely associated with ice habitats. Species such as little auks, guillemots and ivory gulls adhere to the ice edge zone with holes, clearings and leads, as well as the marginal zone of drifting ice. The migration and wintering areas of some populations of seabirds, for example, the common eiders of Novaya Zemlya and Franz Josef Land, have not yet been established. There are only assumptions of varying degrees of validity about the areas of their localization. The validity of these assumptions can only be revealed through further studies of the Arctic avifauna.

Photos taken by Yu.V. Krasnov.

Today in the northern regions there are quite a few a large number of a wide variety of living creatures, and beyond the Arctic Circle, in territories where almost eternal frost reigns, there are also inhabitants represented by some birds and animals. Their body managed to adapt to unfavorable climatic conditions, as well as a rather specific diet.

Mammals

The vast expanses of the harsh Arctic are characterized by snow-covered deserts, very cold winds and permafrost. Precipitation in such areas is very rare, and sunlight may not penetrate the darkness of the polar nights for several months. Mammals existing in such conditions are forced to spend a difficult winter period among the scorching cold of snow and ice.

Arctic fox or arctic fox

Small representatives of the fox species (Alopex lagopus) have long inhabited the Arctic. Predators from the Canidae family appearance resemble a fox. The average body length of an adult animal varies between 50-75 cm, with a tail length of 25-30 cm and a height at the withers of 20-30 cm. The body weight of a mature male is approximately 3.3-3.5 kg, but the weight of some individuals reaches 9.0 kg. Females are noticeably smaller. The Arctic fox has a squat body, a short muzzle and rounded ears that protrude slightly from the fur, which prevents frostbite.

White or polar bear

The polar bear is a northern mammal (Ursus maritimus) from the Bear family, is a close relative brown bear and the largest land predator on the planet. The body length of the beast reaches 3.0 meters and weighs up to a ton. Adult males weigh approximately 450-500 kg, and females are noticeably smaller. The height of the animal at the withers most often varies between 130-150 cm. Representatives of the species are characterized by a flat head and a long neck, and translucent hairs are capable of transmitting only UV rays, which gives the predator’s coat thermal insulation properties.

It will be interesting: why are polar bears white

Leopard seal

Representatives of the species of true seals (Hydrurga leptonyx) owe their unusual name to their original spotted skin and very predatory behavior. The leopard seal has a streamlined body that allows it to develop very high speeds in water. The head is flattened, and the forelimbs are noticeably elongated, due to which movement is carried out with strong synchronized strikes. The body length of an adult animal is 3.0-4.0 meters. The upper part of the body is dark gray in color, while the lower part is silvery-white. There are gray spots on the sides and head.

Bighorn sheep, or chubuk

Artiodactyl (Ovis nivicola) belongs to the genus of sheep. This animal has a medium size and a dense build, a thick and short neck, as well as a small head with rather short ears. The ram's limbs are thick and not high. The body length of adult males is approximately 140-188 cm, with a height at the withers ranging from 76-112 cm and a body weight of no more than 56-150 kg. Adult females are slightly smaller than males. Diploid cells in representatives of this species contain 52 chromosomes, which is less than in any other modern species rams

Muskox

A large hoofed mammal (Ovibos moschatus) belongs to the musk ox genus and the Bovid family. The height of adult individuals at the withers is 132-138 cm, with a weight ranging from 260-650 kg. The weight of females most often does not exceed 55-60% of the weight of the male. The musk ox has a hump-like scruff in the shoulder area, which turns into a narrow rear part. The legs are small, stocky, with large and rounded hooves. The head is elongated and very massive, with sharp and rounded horns, which grow in the animal until the age of six. The hairline is represented by long and thick hair, which hangs almost to ground level.

Arctic hare

iv>

The hare (Lepus arcticus), formerly considered a subspecies of the mountain hare, but today recognized as a separate species. The mammal has a small and fluffy tail, as well as long, powerful hind legs, which allow the hare to easily jump even on high snow. Relatively short ears help reduce heat transfer, and abundant fur allows the northern inhabitant to easily tolerate very severe cold. Long and straight incisors are used by the hare to feed on sparse and frozen arctic vegetation.

Weddell seal

A representative of the family of true seals (Leptonychotes weddellii) is a not very widespread and rather large in body size predatory mammals. The average length of an adult is 3.5 meters. The animal is able to stay under water for about an hour, and feeds in the form of fish and cephalopods The seal hunts for itself at depths of up to 750-800 meters. Weddell seals quite often have broken fangs or incisors, which is explained by the fact that they make special holes through young ice.

Wolverine

The predatory mammal (Gulo gulo) belongs to the mustelidae family. This rather large animal is second only to the sea otter in size in the family. The weight of an adult is 11-19 kg, but females are slightly smaller than males. The body length varies between 70-86 cm, with a tail length of 18-23 cm. In appearance, the wolverine is most likely similar to a badger or a bear with a squat and awkward body, short legs and an arched upward back. Characteristic feature predator is the presence of large and hooked claws.

Birds of the north

Many feathered representatives of the north feel quite comfortable in extreme climatic and weather conditions. Due to the specifics natural features, more than a hundred of the most different types birds are able to survive in areas of almost permafrost. Southern border The Arctic territory coincides with the tundra zone. During the polar summer, several million of a wide variety of migratory and flightless birds nest here.

Seagulls

Numerous representatives of the genus of birds (Larus) from the Gull family live not only in the sea, but also inhabit inland waters in inhabited areas. Many species belong to the category of synanthropic birds. Typically, the gull is a large to medium-sized bird with white or gray plumage, often with black markings on the head or wings. Some of the significant distinctive characteristics are represented by a strong beak, slightly curved at the end, and very well developed swimming membranes on the legs.

White goose

>

A medium-sized migratory bird (Anser caerulescens) from the genus Anser and the duck family Anatidae, it is characterized by predominantly white plumage. The body of an adult is between 60-75 cm long. The weight of such a bird rarely exceeds 3.0 kg. The wingspan of the white goose is approximately 145-155 cm. The black color of the northern bird is predominant only around the beak area and at the tips of the wings. The paws and beak of this bird are pink. Often in adult birds there is a golden-yellow spot.

Whooper swan

A large waterfowl (Cygnus cygnus) from the duck family, it has an elongated body and a long neck, as well as short, backward legs. The bird's plumage contains a significant amount of fluff. The lemon-yellow beak has a black tip. The plumage is white. The young are distinguished by smoky gray plumage with a darker head area. Males and females are practically no different from each other in appearance.

Gaga

The feathered representatives of the genus (Somateria) belong to the duck family. Such birds are united today into three species of diving ducks, which are quite large in size, which nest mainly in the territories of the Arctic coasts and tundra. All species are characterized by a wedge-shaped beak structure with the presence of a wide nail, which occupies the entire upper part of the beak. On the lateral parts of the beak there is a deep recess covered with feathers. The bird comes to the coastline only to rest and breed.

Thick-billed guillemot

The seabird (Uria lomvia) of the auk family (Alcidae) is a medium-sized species. The bird weighs about one and a half kilograms, and in appearance resembles thin-billed guillemots. The main difference is represented by a thicker beak with white stripes, black-brown dark plumage of the upper part and a complete absence of grayish shading on the sides of the body. Thick-billed guillemots are, as a rule, noticeably larger than thin-billed guillemots.

Antarctic tern

The northern bird (Sterna vittata) belongs to the gull family (Laridae) and the order Charadariiformes. The Arctic Tern migrates annually from the Arctic to Antarctica. This small-sized feathered representative of the genus Tern has a body 31-38 cm long. The beak of an adult bird is dark red or black. Adult terns are characterized by white plumage, while chicks are characterized by gray feathers. There are black feathers in the head area.

White or polar owl

A rather rare bird (Bubo scandiacus, Nyctea scandiaca) belongs to the category of the largest birds of the owl order on the tundra. Polar owls are distinguished by their round heads and bright yellow irises. Adult females are larger than mature males, and the average wingspan of a bird is approximately 142-166 cm. Adults are characterized by white plumage with dark transverse streaks, which provides excellent camouflage of a predator against a snowy background.

Arctic partridge

The ptarmigan (Lagopus lagopus) is a bird from the subfamily Grouse and order Galliformes. Among many other galliformes, it is the white partridge that is characteristically distinguished by the presence of pronounced seasonal dimorphism. The color of this bird varies depending on the weather. The winter plumage of the bird is white, with black tail feathers and densely feathered legs. With the onset of spring, the neck and head of males acquire a brick-brown color, sharply contrasting with the white plumage of the body.

Reptiles and amphibians

Too harsh climatic conditions The Arctic does not allow various cold-blooded animals, including reptiles and amphibians, to spread as widely as possible. At the same time, the northern territories have become quite suitable habitat for four species of lizards.

Viviparous lizard

The scaly reptile (Zootoca vivipara) belongs to the family True lizards and the monotypic genus Forest lizards (Zootoca). For some time, such a reptile belonged to the genus Green lizards (Lacerta). A well-swimming animal has a body size of 15-18 cm, of which approximately 10-11 cm is in the tail. The body color is brown, with dark stripes that stretch along the sides and in the middle of the back. The lower part of the body is light in color, with a greenish-yellowish, brick-red or orange tint. Males of the species have a slimmer build and brighter colors.

Siberian newt

The four-toed newt (Salamandrella keyserlingii) is a very striking representative of the salamander family. An adult tailed amphibian has a body size of 12-13 cm, of which less than half is in the tail. The animal has a wide and flattened head, as well as a laterally compressed tail, which is completely devoid of leathery fin folds. The color of the reptile has a grayish-brown or brownish color with the presence of small spots and a fairly light longitudinal stripe in the back area.

Semirechensky frogtooth

The Djungarian newt (Ranodon sibiricus) is a tailed amphibian from the salamander family (Hynobiidae). An endangered and very rare species today, its body length ranges from 15-18 cm, but some individuals reach sizes of 20 cm, of which the tail part occupies a little more than half. The average body weight of a sexually mature individual can vary between 20-25 g. On the sides of the body there are from 11 to 13 intercostal and clearly visible grooves. The tail part is laterally compressed and has a developed fin fold in the dorsal area. The color of the reptile varies from yellow-brown to dark olive and greenish-gray, often with spots.

tree frog

The tailless amphibian (Rana sylvatica) is capable of freezing to the point of ice in the harsh winter. An amphibian in this state does not breathe, and the heart and circulatory system stop. When the weather gets warmer, the frog “thaws out” quite quickly, which allows it to return to normal life. Representatives of the species are distinguished by large eyes, a clearly triangular-shaped muzzle, and a yellow-brown, gray, orange, pink, brown or dark gray-green dorsal area. The main background is supplemented with blackish or dark brown spots.

Fishes of the Arctic

For the coldest regions of our planet, not only many species of birds are endemic, but also various marine inhabitants. Arctic waters are home to walruses and seals, several species of cetaceans, including baleen whales, narwhals, killer whales and beluga whales, as well as several species of fish. In total, the territory of ice and snow is inhabited by just over four hundred species of fish.

Arctic char

Ray-finned fish (Salvelinus alpinus) belong to the salmon family, and are represented by many forms: anadromous, lake-river and lake loaches. Migratory loaches are distinguished by their large size and silvery color, have a dark blue back and sides, covered with light and rather large spots. Widespread lake Arctic char – typical predators spawning and fattening in lakes. Lake-river forms are characterized by a smaller body. On this moment Arctic char populations are in decline.

Arctic sharks

Somniosa sharks (Somniosidae) belong to the family of sharks and the order Katraniformes, which includes seven genera and about two dozen species. The natural habitat is Arctic and sub-Antarctic waters in any oceans. Such sharks inhabit continental and island slopes, as well as shelves and open ocean waters. Moreover, the maximum recorded body dimensions do not exceed 6.4 meters. The spines located at the base of the dorsal fin are usually absent, and the edge of the upper lobe of the caudal fin is characterized by a notch.

Arctic cod or polar cod

Arctic cold-water and cryopelagic fish (Boreogadus saida) belongs to the cod family (Gadidae) and the order Gadiformes. Today it is the only species from the monotypic genus of Arctic cods (Boreogadus). The body of an adult individual has a maximum body length of up to 40 cm, with significant thinning towards the tail. The caudal fin is characterized by the presence of a deep notch. The head is large, with a slightly protruding lower jaw, large eyes and a small antennae at chin level. The top of the head and back are grayish-brown in color, while the belly and sides are silvery-gray.

Eel-pout

Sea fish (Zoarces viviparus) belongs to the eelpout family and the order Perciformes. The aquatic predator has a maximum body length of 50-52 cm, but usually the size of an adult does not exceed 28-30 cm. The eelpout is distinguished by a rather long dorsal fin with short spine-like rays at the back. The anal and dorsal fins are fused together with a caudal fin.

Pacific herring

Ray-finned fish (Clupea pallasii) belongs to the herring family (Clupeidae) and is a valuable commercial object. Representatives of the species are distinguished by a rather weak development of the ventral keel, very clearly visible exclusively between the anal and ventral fin. Typically pelagic schooling fish are characterized by high motor activity and constant collective migrations from wintering and feeding areas to spawning areas.

Haddock

The ray-finned fish (Melanogrammus aeglefinus) belongs to the cod family (Gadidae) and the monotypic genus Melanogrammus. The body length of an adult varies between 100-110 cm, but typical sizes are up to 50-75 cm, with an average weight of 2-3 kg. The body of the fish is relatively high and slightly flattened on the sides. The back is dark gray with a purple or lilac tint. The sides are noticeably lighter, with a silvery tint, and the belly is silvery or milky white. The haddock has a black lateral line on its body, below which there is a large black or blackish spot.

Nelma

The fish (Stenodus leucichthys nelma) belongs to the salmon family and is a subspecies of the whitefish. Freshwater or semi-anadromous fish from the order Salmonidae reaches a length of 120-130 cm, with a maximum body weight of 48-50 kg. A very valuable species of commercial fish is a popular breeding object today. Nelma differs from other members of the family in the structural features of its mouth, which gives this fish a rather predatory appearance compared to related species.

Arctic omul

Commercially valuable fish (lat. Coregonus autumnalis) belongs to the genus whitefish and the salmon family. A migratory type of northern fish fattens in coastal waters Arctic Ocean. The average body length of an adult reaches 62-64 cm, with a weight in the range of 2.8-3.0 kg, but larger individuals are found. A widespread aquatic predator preys on a wide variety of large representatives of benthic crustaceans, and also eats juvenile fish and small zooplankton.

Spiders

Arachnids are obligate predators that demonstrate the highest potential for mastering the complex Arctic environment. The Arctic fauna is represented not only by a significant number of boreal spider forms coming from the southern part, but also by purely Arctic species of arthropods - hypoarcts, as well as hemiarcts and evarcts. Typical and southern tundras are rich in a wide variety of spiders, differing in size, hunting method and biotopic distribution.

Oreoneta

Representatives of the genus of spiders belonging to the family Linyphiidae. This arachnid arthropod was first described in 1894, and today about three dozen species are classified in this genus.

Masikia

Representatives of the genus of spiders belonging to the family Linyphiidae. The first inhabitant of the Arctic territories was described in 1984. Currently, only two species are classified in this genus.

Tmetits nigriceps

A spider of this genus (Tmeticus nigriceps) lives in the tundra zone, is distinguished by an orange-colored prosoma, with the presence of a blackish-cephalic region. The spider's legs are orange, and the opisthosoma is black. The average body length of an adult male is 2.3-2.7 mm, and that of females is between 2.9-3.3 mm.

Gibothorax tchernovi

The spin species, belonging to the taxonomic classification Hangmatspinnen (linyphiidae), belongs to the arthropod arachnids of the genus Gibothorax. Scientific name This species was first published only in 1989.

Perrault Polaris

One of the currently insufficiently studied species of spiders, first described in 1986. Representatives of this species are classified in the genus Perrault, and are also included in the family Linyphiidae.

sea ​​spider

Sea spiders have been discovered relatively recently in the polar Arctic and in the waters of the Southern Ocean. Such aquatic inhabitants are gigantic in size, and the length of some of them exceeds a quarter of a meter.

Insects

The large number of insectivorous birds in the northern regions is due to the presence of numerous insects - mosquitoes, midges, flies and beetles. The insect world in the Arctic is very diverse, especially in the polar tundra region, where with the onset of the summer season countless mosquitoes, gadflies and small midges appear.

Burning midge

The insect (Culicoides pulicaris) is capable of producing several generations during the warm season, and is today a widespread and common blood-sucking midge, not found only in the tundra.

Karamora

Insects (Tipulidae) belong to the family Diptera and the suborder Nematocera. The body length of many long-legged mosquitoes varies between 2-60 mm, but sometimes larger representatives of the order are found.

Chironomidae

The mosquito (Chironomidae) belongs to the family of the order Diptera and owes its name to the characteristic sound that the insect's wings make. Adults have underdeveloped mouthparts and are harmless to humans.

Wingless springtails

The northern insect (Collembola) is a small and very nimble arthropod, a primarily wingless form, usually resembling a tail with a common jumping appendage.

Animals living in the Arctic

List of Arctic animals with pictures and interesting information. You can get more information about many of the animals by clicking on the images.

Common arctic fox

The Arctic fox has some features that allow it to live in the difficult conditions of the Arctic. The most notable feature is its fur, which changes color from brown (summer coloration) to white (winter coloration). A thick fur coat provides the arctic fox with good camouflage and excellent protection from the cold.

Arctic hare

Arctic hares dig holes underground. There they sleep and hide from frost and predators. Hares run very fast, reaching speeds of up to 60 km/h.

Arctic terns are the true conquerors of nature. These incredible birds fly over 19,000 km per year. They can be seen in broad daylight much more often than any other animals and birds. Thanks to migration, terns have two summers a year.

This is one of the Arctic predators that live in the coldest areas of northern Canada and other Arctic territories. The Arctic wolf is a subspecies of the gray wolf and is smaller in size than the Northwestern wolf, another subspecies of wolfs.

Since the polar wolf is found in the Arctic, it, unlike other subspecies, is least likely to be exterminated by people.

Bald Eagle

The bald eagle is national symbol America. Its habitat extends far beyond the Arctic. You can meet this beautiful bird throughout North America - from Canada to Mexico. The eagle is called a bald eagle due to the white feathers growing on its head. These birds often catch fish: diving down, they snatch fish out of the water with their paws.

Belukha

Beluga whales are found off the coast of Russia, North America and Greenland. They are social animals and generally prefer to live in small groups of about 10 individuals. The white color perfectly camouflages them under the Arctic ice.

Caribou/reindeer

In Europe, caribou is better known as reindeer. The deer has adapted well to the cold climate of the North. It has large cavities in its nose that serve to heat the frosty air. During the winter, the animal's hooves become smaller and harder, making it much easier for the deer to walk on ice and snow. During migration, some reindeer herds move vast distances. No other land mammals living on our planet are capable of this.

Dalla Ram

The habitat of Dall's sheep is in the subarctic regions of North America. These animals are very agile and dexterous, which helps them in most cases to avoid attacks from predators.

Ermine

The stoat belongs to the mustelidae family. The name "ermine" is sometimes used only to refer to the animal in its white winter coat.

Stoats are fierce hunters that eat other rodents. Often they even move into the holes of their victims, instead of digging their own shelters.

Arctic shark

Arctic sharks are mysterious animals. This photo was taken by the US National Oceanic and Atmospheric Administration.

Arctic sharks are mysterious giants that live in the Arctic region. This photo was taken by the US National Oceanic and Atmospheric Administration. Click on the image to learn more about this animal.

Most often, polar sharks are found in the North Atlantic Ocean off the coast of Canada and Greenland. Of all shark species, they are the most northern. These animals swim quite slowly and prefer to catch their prey while it is sleeping. Also, polar sharks do not hesitate to finish eating what other predators left after their meals.

harp seal

At birth, harp seal pups have a fur coat yellow color. It turns white after three days. As the animal matures, its color becomes silver-gray. Harp seals have a thick layer of subcutaneous fat that retains heat well. The flippers of seals serve as a kind of heat exchangers: in summer, excess heat is removed through them, and in winter, due to the movements of the flippers in the water, the body heats up.

Lemming

Lemmings are small rodents with long, soft fur. They are herbivores and feed on grass, leaves and roots of plants. In winter, lemmings remain active and do not hibernate. Before the onset of winter, they stock up and also burrow under the snow to search for food.

Elk

Elk is the largest representative of the deer family. Eagles are most often found in Alaska, Canada, Russia and Scandinavia. Moose have one feature that distinguishes them from other representatives of the deer family. This peculiarity lies in the fact that they are solitary animals and do not live in herds. As a rule, elk move slowly, without haste. But a frightened or angry forest giant can pose a serious danger.
