It is the sole surviving member of the family Odobenidae, one of three lineages in the suborder Pinnipedia along with true seals (Phocidae) and eared seals (Otariidae). Their blubber keeps them warm in frigid waters. With these pouches inflated they can rest effortlessly on the surface, and will even sleep in the water with their heads tossed back, bobbing dreamily.

Some scientists believe that the Arctic could be entirely without ice during the summer months within 20 to 25 years. In a 2009 study in The Journal of Heredity, researchers presented a . [75], Aside from the large numbers of organisms actually consumed by the walrus, its foraging has a large peripheral impact on benthic communities. While swimming, walruses become graceful and use full-body movements to glide through the water. This increased skin circulation sheds excess body heat. The species name rosmarus is Scandinavian.

Atlantic walruses inhabit coastal areas from northeastern Canada to Greenland, while Pacific walruses inhabit the northern seas off Russia and Alaska, migrating seasonally from their southern range in the Bering Seawhere they are found on the pack ice in winterto the Chukchi Sea. This more widely separates lactating females from their calves, increasing nutritional stress for the young and lower reproductive rates.

Walruses are famous for their huge tusks, but there are many other facts about these giant marine mammals you may not know! The primary functions of the tusks are establishing social dominance and hauling out onto ice or rocky shores.

They use them to haul their enormous bodies out of frigid waters, thus their tooth-walking label, and to break breathing holes into ice from below. This strategy of delayed implantation, common among pinnipeds, presumably evolved to optimize both the mating season and the birthing season, determined by ecological conditions that promote newborn survival. The greatest threat to walruses is climate change Melting sea ice means more Pacific walruses are resting on land, further from their feeding grounds. [17][18] Abundant walrus remains have also been recovered from the southern North Sea dating to the Eemian interglacial period, when that region would have been submerged as it is today, unlike the intervening glacial lowstand when the shallow North Sea was dry land. She will exchange kisses, and hold the baby in her flippers while floating in the water. The mother will usually seek a private ice float when she's ready to give birth.
