The polar bear is a mammal. It lives in the frozen Arctic, on sea ice around the North Pole. Its home is freezing cold.
The polar bear eats seals, fish and bird eggs. It waits beside holes in the ice for seals to come up for air.
The polar bear has a thick layer of fat called blubber. This keeps it warm in freezing water. It is about 3 meters long.
Baby polar bears are called cubs. Cubs are born in a snow den in winter and stay with their mother for about two years.
