The range of walruses is circumpolar, that is, it encloses the North Pole. Unlike seals walruses avoid extensive water spaces and endless pack (long-term) ice, so they are found only on the coasts of Europe, Asia, North America and the Arctic islands. Due to the reduction in abundance, the walrus area now exploded into several unconnected sites. The greatest number of these animals lives on the Chukchi Peninsula, the banks of the Bering Strait and the Labrador Peninsula, and few walruses in the western and central parts of the Eurasian coast. Seasonal migrations of walruses are very short: in winter they move to the south, but only a few hundred kilometers, which is not enough for such animals.
Walruses lead a herd life. They live in groups of 10-20 individuals, but can form rookeries up to 100-3000 individuals (more often such large groups are created by females). Unlike other pinnipeds, walruses at rookeries try to lie as close to each other as possible, and they do it not from lack of space, but quite consciously. Even in the presence of a free area, a herd of walruses does not disperse along the coastline, but keeps cumulatively, just as they dive together into the water. In relation to relatives, walruses are more peaceful than other seals. Even in the mating season, they do not have fatal battles, adults do not squeeze the young as it happens in other species. There is no hierarchy in the herd, all members of the herd are less equal in their rights.
