Blubber from whales and seals contains omega-3 fatty acids and vitamin D. [15] Without the vitamin D, for example, the Inuit and other natives of the Arctic would likely suffer from rickets. There is evidence blubber and other fats in the arctic diet also provide the calories needed to replace the lack of carbohydrates which are found in the ...
It takes roughly six weeks to complete, with seals ridding themselves of dead hair by scratching and rubbing against the sand or rocks. Seals gather to moult their worn-out winter fur on stretch ...
Weddell seals are commonly found on fast ice, or ice fastened to land, and gather in small groups around cracks and holes within the ice. [11] In the winter, they stay in the water to avoid blizzards, with only their heads poking through breathing holes in the ice. [8] These seals are often observed lying on their sides when on land.

Seals range in size from the 1 m (3 ft 3 in) and 45 kg (100 lb) Baikal seal to the 5 m (16 ft) and 3,200 kg (7,100 lb) southern elephant seal. Several species exhibit sexual dimorphism. They have streamlined bodies and four limbs that are modified into flippers. Though not as fast in the water as dolphins, seals are more flexible and agile ...
Baikal seals mate in the water towards the end of the pupping season. With a combination of delayed implantation and a nine-month gestation period, the Baikal seals' overall pregnancy is around 11 months. Pregnant females are the only Baikal seals to haul out during the winter. The males tend to stay in the water, under the ice, all winter.
During winter and spring, it hauls out on pack ice to breed, molt, and give birth. During this time, it is found at the ice front in the Bering and Okhotsk Seas. [10] During the winter and spring, the ribbon seal lives in open water, though some move south as the ice recedes with warmer temperatures. Little is known about its habit during this ...
