But again, a bear helps with the filming. Sealed with a kiss, the couple’s whirlwind romance will last three weeks.
Out on the frozen sea, a young male has killed a seal. He caught it when it surfaced through a breathing hole in the ice. To film from a different angle, blizzard-cam deploys 1 snowball-cam. This technical miracle rolls with no visible moving parts. Its lens even boast a self-righting mechanism 2, a close-up reveals that he's eating the blubber. This provides the most nutrition and is always eaten first. Seals make up 95% of a polar bear's diet and are only found near the sea ice.
The two cub 3 family are attracted to the frozen sea to hunt seals as well. She hunts the pups of ringed seals that hide in snowy dens 5 on the ice. She finds them by smell, even a meter down. She pile-drives the snow with a force of two tons, but the roof of the den 4 holds.
Back at the carcass, the spy-cams stay on to film bears attracted to the leftovers 6. The mother and a single cub--she could smell their remains 7 from 20 miles away. In the den, she spent six months without eating while the males fattened 8 up on seals.
