Walruses occupy a nearly circumpolar region of the Arctic. Three distinct subspecific populations are recognized: 1) Atlantic (Odobenus rosmarus rosmarus), which lives in the eastern Canadian Arctic and Greenland east to Novaya Zemlya; 2) Pacific (O. r. divergens), living in the Bering Sea and adjacent Arctic Ocean; 3) Laptev Sea (O. r. laptevi), occupying the Laptev Sea, north of Siberia. Some taxonomists do not recognize the Laptev Sea population as a separate subspecies. Unless otherwise specified, all walruses will be treated here as one population, Odobenus rosmarus (Jefferson et al. 1993; Nowak 1991; Parker 1990).
