[4] Male Atlantic walrus weigh an average of 900kg (2,000lb). [60], Even though walruses can dive to depths beyond 500 meters, they spend most of their time in shallow waters (and the nearby ice floes) hunting for food. Walruses depend on sea ice as a platform for feeding and resting, and a warming Arctic is disrupting their normal patterns. As they get hungry, they need to return to the sea.
