Atlantic walrus
The walrus is the second largest seal in the world, after the elephant seal, and can weigh up to 2 tons (4,400 pounds). It is found in the Arctic polar region, with two subspecies. The Pacific walrus (Odobenus rosmarus divergens) lives between Alaska and Russia, while the Atlantic walrus (Odobenus r. rosmarus) is native to Greenland, Canada, Svalbard and Siberia.
Tusks and vibrissae
Its most recognizable physical feature is its tusks. In particularly large males, these can be up to one meter (3 ft 3 in) long. They serve not only as a defense, but also as a symbol of dominance. The walrus also uses its tusks to pull itself out of the water and to punch holes in the ice. The walrus spends most of its time in shallow waters and on sea ice. It is a predator and feeds mainly on bivalve mollusks and other invertebrates that it digs up from the seabed during its dives, which can last up to 30 minutes. The long vibrissae on its upper lip help the walrus to orient itself during the dives. Occasionally, however, it also preys on larger animals, such as seals or birds.
Significance for humans
For the indigenous peoples of the Arctic, walruses have great cultural significance and have served not only as a food source but also as a material for clothing, tools, housing and boats.
