It is believed that mammals are able to live only at sufficiently comfortable ambient temperatures.But animals arctic desert successfully refute this assertion.Of course, some of them are not only mammals but also poultry.
most famous representative of the local fauna is a polar bear.By the way, not so long ago it became known that the term "white" does not apply to it.His hair is almost colorless, and the skin - black.Fur strands are of particular structure: they are hollow, filled with air.Given that millions of hairs, they are very effective thermal insulation.So effective that in a particularly "hot" days (at a temperature no higher than -5 degrees) long bear swims in the ocean, where the water temperature barely reaches 5-6 degrees Celsius.
way, these animals arctic desert - food taboos for the Eskimos.For a long time scientists did not understand this strange ban.For an adult male - it is almost a ton of meat!Later it was found that their flesh is often struck by parasites in the liver and contains as much vitamin A, even in a piece of 100 g can be deadly.
no less famous fox.These animals arctic deserts perform the same function as our foxes.They are nurses countryside, eating feeble and sick animals, collecting discarded surf on the coast of the corpses.Do not disdain even plant food, happy eating moss and berries cloudberries.
In addition, many seals in the Arctic.Their number is greatly reduced as a result of predatory fishing in the 19-20 th centuries.It is expected that some sub-species (or species) in those years, were completely destroyed.Whatever it was, but today these animals arctic desert significantly increased their population.
They have been known to derive their young on the beach.In the breeding season large areas of desert coastline before turning in at the kindergarten.It is very noisy, as thousands of males continually converge in fights over females.
their relatives are walruses.These arctic animals in general was almost extinct due to their unsustainable destruction.They killed not so much because of the meat and fat, as for their tusks.By its value, they have already overtaken elephant tusk.Of these, curry stunningly beautiful carved statues, and this skill local people pass on from generation to generation.In addition, there are many silliest beliefs that crushed walrus tusks being treated for anything: from prostatitis and ending with Alzheimer's.This encourages poachers on their prey, because the rich customers willing to pay any money for this "miracle" drug.
Thus, the Arctic desert, animals which so diverse - not a solitary place.On the rocky slopes of thousands of birds nest (the famous bird colonies), the sea home to hundreds of species of fish and large mammals.
Yes, their life does not seem easy, but its stubborn desire to survive in this harsh edge they show the diversity and adaptability of life forms.
