Musk Ox Family
Inupiat Eskimos call it "omingmak" or "the bearded one." Shaggy and social, with an almost surreal quality, the musk ox, more than any other animal, conjures up images of the cold, remote arctic. Image credit: National Park Service

The haunting sounds of bowhead whales, which sing their songs under Arctic ice through long, dark polar winters, have been recorded in unprecedented detail.
Listen: The Rare, Beautiful Songs of Bowhead Whales

A Weddell seal sports a video data recorder that scientists use to create a three-dimensional map of its movement in the water as it hunts for prey. Researchers hope to learn more about their hunting behavior during late-winter darkness.
