They require large areas of shallow water (80 m or less) with bottom substrates that support a productive bivalve community, the reliable presence of open water over feeding areas, and suitable ice … Distribution The Atlantic walrus ranged historically from the central Canadian Arctic in the west The subspecies received the name of the Western walrus of Eurasia and is listed in the Red Book of Russia, as rare and prone to decline. APPEARANCE The adult male walrus is huge and weighs from 900 kg to 1400 kg. Walruses have a disjointed circumpolar distribution.

The commercial harvesting of walrus in the 19th and 20th centuries resulted in a rapid decrease of walrus across their Arctic ranges, including the extirpation of the Northwest Atlantic population. Atlantic walruses range from central Canada to the Kara Sea, Russia. In Canada and West Greenland, Atlantic walruses (Odobenus rosmarus rosmarus) are commonly found in productive shallow water areas with their latitudinal range extending from the Ontario coast of Hudson Bay ( ~ 53°N) to southern Kane Basin ( ~ 79°N). In the Pacific, adult male walruses reach about 3.6 m in length and weigh 880-1,557 kg; adult females are about 3 m and … Atlantic walruses range from Canada to northern Europe, while Pacific walruses range from Alaska to northern Russia. Males tusks have a length of 34 to 38 cm, in females from 27 to 33 cm. The Pacific subspecies is larger than the Atlantic.

The Atlantic walrus is the The Atlantic walrus is the smallest subspecies: the average body length of males is 2.5–3 m, the females are much smaller. The low intrinsic capacity of the population to increase, mainly due to infrequent production of young (every three years), means that Atlantic walrus are particularly susceptible to additional mortality from human activities. Atlantic Walrus Northwest Atlantic population. The taxonomic status of walruses inhabiting the Laptev Sea is uncertain. Location: Northern Atlantic and Pacific Oceans as well as the Laptev Sea, which is part of the Arctic Ocean.
