Book excerpt: "The walrus, Odobenus rosmarus, is a circumpolar species of arctic and sub-arctic waters and is geographically isolated into three or more morphologically distinct groups. The Eastern Canadian Arctic and West Greenland group ranged as far south as Sable Island and the Gulf of St. Lawrence in historic times, but unrestricted commercial exploitation led to a serious decline in numbers and a withdrawal of the group to the more northern and inaccessible parts of its range. The advent of the rifle into the Eskimo economy with consequent wasteful methods of hunting caused further serious reductions in the walrus herds and necessitated the introduction of restrictive hunting measures." --
