Do polar bears cover their nose?
Do polar bears cover their nose with their paw to hide? According to this “myth”, polar bears cover their black nose with a paw so that seals can’t see them during a hunt.

How do polar bears cool off?
Going swimming or taking a cool bath can take the edge of the heat quickly. Polar bears are known to take a swim to cool down, including this polar bear in the Beaufort Sea off the coast of Alaska, who lives on land in the summer. Whether walking on land or on ice, these well-insulated bears easily become too warm.
