Seal meat hanging to dry on St. Lawrence Island. The study showed significant differences in nutritional composition from one seal to another. This may have been due to the highly varied age and size of the seals tested. In general, both the meat and blubber can be considered to be high quality food in terms of bioactive components and nutrients.
The fur seal yields a valuable fur; the hair seal has no fur, but oil can be obtained from its fat and leather from its hide. [9] Seals have been used for their pelts, their flesh, and their fat, which was often used as lamp fuel, lubricants, cooking oil, a constituent of soap, the liquid base for red ochre paint, and for processing materials such as leather and jute.

The meat, blubber and skin of pinnipeds have traditionally been used by indigenous peoples of the Arctic. Seals have been depicted in various cultures worldwide.
Blubber under the seal's skin helps to maintain body temperature. Females outlive males (30–35 years versus 20–25 years). Harbor seals stick to familiar resting spots or haulout sites, generally rocky areas (although ice, sand, and mud may also be used) where they are protected from adverse weather conditions and predation, near a foraging ...
Elephant seals are shielded from extreme cold more by their blubber than by fur. Their hair and outer layers of skin molt in large patches. The skin has to be regrown by blood vessels reaching through the blubber. When molting occurs, the seal is susceptible to the cold, and must rest on land, in a safe place called a "haul out". Northern males ...
Baikal seals can dive up to depths of 400 m (1,300 ft) [4] and stay underwater for more than 40 minutes. [1] Most dives last less than 10 minutes and generally only 2–4 minutes. [1] Baikal seals have two litres more blood than any other seal of their size and can stay underwater for up to 70 minutes if they are frightened or need to escape ...
In recent years, the number of grey seals has been on the rise in the west and the U.S. [39] and Canada [40] there have been calls for a seal cull. Seal pup a few days after birth. Seal pup first-year survival rates are estimated to vary from 80 to 85% [41] [42] to below 50% [43] depending on location and conditions. Starvation, due to ...
