Walrus: Life on Thin Ice: The walrus is one of the Arctic’s most enigmatic animals. With three-foot long tusks and a droopy mustache, everyone knows what these marine mammals look like, but few ever see them in the wild. Most of the world’s walrus, about 250,000 of them, live in the frigid seas between Russia and Alaska. This film documents an Arctic adventure to uncover the hidden lives of these lumbering giants and the threats they face as climate change shrinks the sea ice. What kind of future lies ahead for walruses in the wild?
