Airborne fumes (gasoline, solvents, etc.) These ever growing gatherings can be deadly, especially for young calves. [59], The isolated population of Laptev Sea walruses is confined year-round to the central and western regions of the Laptev Sea, the eastmost regions of the Kara Sea, and the westmost regions of the East Siberian Sea.

This is why the Latin name for the walrus translates roughly to "tooth walker". [17][18] Abundant walrus remains have also been recovered from the southern North Sea dating to the Eemian interglacial period, when that region would have been submerged as it is today, unlike the intervening glacial lowstand when the shallow North Sea was dry land. (2020, August 28). The word pinniped comes from the Latin words for wing- or fin-footed, in reference to the fore- and hindlimbs of these animals, which are flippers.
