The walrus is a noble beast. Seeing one should easily serve as a life highlight for any human. So witnessing 35,000 of these majestic, bearded behemoths congregating along the shore of Alaska could qualify as a once-in-a-lifetime revelation—except the walruses probably aren’t very happy to be there. The 2000-kilogram marine mammals would much prefer to be living out their days on sea ice floating in shallow waters. But, unfortunately, rising temperatures have caused a dearth of such habitat and forced the animals ashore, Slate reports. When walruses gather in such large numbers, the risk for stampedes—which can be caused by polar bears, engine noise, or hunters—becomes a concern.
