Narwhal

The narwhal (Monodon monoceros), is a medium-sized toothed whale that,  along with the beluga whale is one of two living species of whale in the Monodontidae family. It lives year-round in the Arctic waters around Greenland, Canada, and Russia. The most conspicuous characteristic of the male narwhal is a single long tusk, a canine tooth that projects from the left side of the upper jaw, through the lip, and forms a left-handed helix spiral. A tusk grows throughout life, reaching a length of about 5-10 feet in length. It is hollow and weighs around 22 pounds. About one in 500 males has two tusks, occurring when the right canine also grows out through the lip. Only about 15 percent of females grow a tusk, which typically is smaller than a male tusk, with a less noticeable spiral. Collected in 1684, there is only one known case of a female growing a second tusk.

Musk Ox

The musk ox (Ovibos moschatus) is an Arctic mammal of the family Bovidae, noted for its thick coat and for the strong odor emitted during the seasonal rut by males, from which its name derives. This musky odor is used to attract females during mating season. Its Inuktitut name “umingmak” translates to “the bearded one”. Muskoxen primarily live in the Canadian Arctic and Greenland, with small introduced populations in Sweden, Siberia, Norway, and Alaska.

Walruses (Odobenus rosmarus) rest on ice in Alaska. Environmental activists want the US Fish and Wildlife Service to reconsider using anchored rafts in the Chukchi Sea to provide walruses a platform on which to rest. Diminished sea ice has forced walruses to Russian and Alaskan coasts in herds of 35,000 or more.Adult males in the Pacific can weigh more than 2,000 kg (4,400 lb)[ and, among pinnipeds, are exceeded in size only by the two species of elephant seals.
