Walruses have been traditionally hunted by Arctic people for their meat, hide and [[ivory]] for thousands of years. In recent times, hunting for ivory has severely impacted walrus populations. Although now protected, some [[poaching]] continues. The only other animal that preys upon adult walrus is the [[killer whale]], though [[Polar Bear]]s will sometimes attack calves.
