Seal muscles also store oxygen, and the spleen, an organ that stores oxygen-rich blood, is exceptionally large in seals, serving as a kind of biological scuba tank.

 SCS: Harp Seal (Phoca groenlandica)
All three harp seal populations are commercially hunted, usually on their breeding grounds, and the current hunt in Canada has been described as the "largest slaughter of marine mammals in the world".
For the 2001 sealing season Norwegian vessels were allocated hunt quotas of 15,000 adult harp seals on the West Ice (2 non-suckling pups deemed equal to 1 adult) and 5,000 adult harp seals on the East Ice (2.5 non-suckling pups deemed equal to 1 adult).
Seal meat from the hunt was previously sold as food to fur farms but this has not occurred for the last few years as the farms are importing cheaper dried meat from Germany, many seal carcasses being left to rot near processing plants as a result.
