On land, the walrus Atlantic clumsy, he barely moved, fingering with all four flippers. But in the ocean it feels great, sliding easily in the water column. Apparently, that is why he is on a stony beach lay, and in marine waters, actively moving.

Shellfish – the main food of the mighty beast. Although it happens that he attacks baby seals. Giant animal feels full after eating 35-50 kg of food.

The Mating season and reproduction

Life expectancy Atlantic walrus – 45 years. He slowly Matures. The sexual maturity he begins to 6-10 years. Walruses are not only able to doze off, burp, growl, engage in fights, but also to bark.

The Cubs have her appear once in a couple years. After all, the mother has to nurse the pup for up to two years. And Morata males remain with the mother for up to 5 years. The female never leaves the herd (by and large his and form females with cubs).

Habitat

Walruses live in the discharged ice fields, the clearings of sagebrush in the open ocean. For life, they choose a water depth of 20-30 meters. Rookery prefer to arrange on the ice and rocky coasts. Their annual migration is caused by the movement of the ice. They climbed on the drifting ice floe, floating like a ship, to places familiar habitat, where, once out on the land, arrange the rookeries.

Distribution

These pinnipeds live along the coasts of the Barents and Kara seas. They are chosen bays, lagoons, and lips, isisascii Bank of multiple Islands in this region. Ice and coastal rookeries of subspecies scattered on the Land of Franz Joseph.

The North-Eastern end of Novaya Zemlya – a place that inhabit the Atlantic walrus and always comes back. In the Eastern regions of the Kara sea it will meet not often. It suits their abode in the White sea, on the Kanin Peninsula, the Islands of Kolguev and Vaigach.

He liked her, and the East coast of the canadian Arctic. In this region, his abode became the Bay and Hudson Strait, Frobisher Bay and Fox, Affinova Earth, Devon island.

Limiting causes

The population of the mighty beast fell sharply due to increased fishing. Particularly hard hitthe Atlantic walrus that lives in the Kara sea. Pinnipeds were brutally exterminated in the XIX century. In some regions they are destroyed completely. The strongest to exterminate the population has been in the canadian Arctic, Greenland, Svalbard.

In our days, the number of the beast limit the rapid management of a person. Especially the occurrence of oil and gas companies involved in the development of new fields. They catastrophically pollute the natural habitats of Atlantic giants, expelled them from populated areas. Species with low potential it is difficult to provide inadequate opposition to fishing stress and other anthropogenic aspects.

Walruses affect 10 species of helminths. Diseases and causes of death of pinnipeds scientists has not been elucidated. Natural enemy populations are considered as killer whales and polar bears.
