A necessary tool of the trade, the big paws of a polar bear are used to swat seals as they surface through holes in the ice. Seals create their own breathing holes in the pack ice called aglus or use natural holes - a polynya or lead.
A polar bear will lay in wait at a breathing hole, polynya or lead and use its powerful limbs and paws to knock out a surfacing seal. The claws are used to grasp the prey as well as for added traction on the ice.
