Dives during the winter are also deeper and longer than those in the summer. It is known that the hooded seal is generally a solitary species, except during breeding and molting seasons. During these two periods, they tend to fast as well. The seals mass annually near the Denmark strait around July, at the time of their molting periods, to mate.
The Saimaa ringed seal is closely related to the Ladoga ringed seal, the populations likely became isolated from the Baltic ringed seal around the same time. The Saimaa ringed seal lives solely within Saimaa, a large freshwater lake in the regions of South Savo, South Karelia, and North Karelia in Finland. Current estimates place the size of ...
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.
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.
The harbor (or harbour) seal (Phoca vitulina), also known as the common seal, is a true seal found along temperate and Arctic marine coastlines of the Northern Hemisphere. The most widely distributed species of pinniped (walruses, eared seals, and true seals), they are found in coastal waters of the northern Atlantic and Pacific oceans, Baltic ...
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 ...
The average daily food requirement is estimated to be 5 kg (11 lb), though the seal does not feed every day and it fasts during the breeding season. Recent observations and studies from Scotland, The Netherlands, and Germany show that grey seals will also prey and feed on large animals like harbour seals and harbour porpoises.
