Polar bears have wide front paws with slightly webbed toes that help them swim. They paddle with their front feet and steer with their hind feet. Paw pads with rough surfaces help prevent polar bears from slipping up on the ice.
Polar bears have been known to swim 100 miles (161 kilometers) at a stretch.
