Polar bears are excellent swimmers and may search a wide range for food. It’s the most carnivorous species, eating 98.5% of its diet meat. The main prey is seals, and even larger species such as walruses and beluga whales. They also prey on seabirds, fish, small mammals, and sometimes clean up carrion. They occasionally eat berries or plant roots during the summer. At the end of spring and summer, they will come to the seaside to take the seaweed to supplement the minerals and vitamins the body needs.
Polar bears are found in ice-covered waters throughout the Arctic Circle. In a region where the Arctic sea ice completely melts each summer, polar bears are forced to spend months on land, where they feed mostly on stored fat until the sea surface freezes.
