Polar bears can walk effortlessly across icy surfaces because Super-small structures on the bears’ paw pads offer extra friction, The structures on the bears’ paws work by helping slow or stop movement between the two surfaces that are touching, That extra grip helps the polar bears from slipping on the snow. The people who are in this group studying bear’s paws are Ali Dhinojwala, Nathaniel Orndorf, and Austin Garner. Their Work was posted on November 2022. The group compared the paws of several bears. They looked at polar bears, brown bears, American black bears, and sun bears, but the only bear who had no grip on their paws were the sun bears. The polar bear's paws looked different Their bumps were taller than the other bears that they have been comparing them to, Next the team made models of the bumps, Next, the scientists tested the models on lab-made snow. The tests showed that taller bumps seem to give more traction or grip. However, with a closer look, the paw pads of polar bears are smaller than those of other bears that they have studied plus the polar bear's paws had fur on them. In addition, these features might allow the Arctic animals to save body heat as they walk on ice, However, smaller paws can have difficulties, which means polar bears have less paw space to grab the ground than bears with larger pads. As a result, that could be why their smaller pads are extra grippy.
