Pacific walruses usually make their residence floating on ice sheets out in the sea. But this year, the absence of  tundra ice has left them crowding Alaskan beaches – up to 20,000 at one point this summer!  This occurrence is so unusual, scientists are worried about the safety of the animals. Easily spooked, walruses could trample each other to death in a stampede. The Today Show reports on the phenomenon from Point Lay, Alaska, in “Without sea ice, walruses struggle to adapt.”
