Bear Hug! Polar Bears Snuggle Up in the Snow
Two polar bear cubs rolling around in below-zero temps still managed to have a blast together, and were photographed mid-hug by British photographer Oliver Smart, who was traveling in a speed boat off Alaska's Barter Island.
"This pair were hilarious because they were squabbling constantly like siblings do, and it was very funny," Oliver says. "I thought the smile on the bear as they embraced was appropriate for such a tender moment."
