Polar bears are the largest bear in the world. They only live in the Arctic and are well adapted to live there. To keep warm, their skin is actually black (which keeps in heat) and they have a four inch layer of fat under their skin. The pads on their feet have a non-slip surface that lets them walk easily on ice. Their paws are webbed which helps to make them excellent swimmers. They also have sharp claws to help them dig through the ice and snow.
Polar bears are carnivores, which means they eat only meat. They mostly eat seals, but will also eat walruses and dead whales if they find them. They have no natural predators and they have no fear of humans, which makes them extremely dangerous.
Male polar bears are larger than females and can weigh anywhere between 400 and 700 pounds. They typically live alone, except when a female is raising her cubs. She will dig a den in the snow and give birth to one or two cubs which will stay with her for about three years. Most polar bears live until about 25 years old.
