On a calm day in the Arctic the grunts and bellows of the Atlantic walrus can be heard from many kilometres away. It is not uncommon to happen upon sprawling groups of the moustached animals hanging out on chunks of ice floe with their dramatic tusks engaging in the odd turf war when taking a break from foraging for food.

There are two sub-species of walrus: The Pacific walrus which inhabit the Bering, Chukchi and Laptev seas and the walruses you see in the Canadian Arctic, called the Atlantic walrus. They live east of Somerset Island, notably in Baffin Bay, Davis Strait, Foxe Basin, and the mouth of Hudson Bay.
