What kind of a bear is found in the Arctic tundra?

The polar bear (Ursus maritimus) is the only bear species found in the Arctic tundra. Polar bears are perfectly adapted to the freezing conditions of the Arctic, with thick fur, a layer of blubber, and large paws that help them distribute their weight on ice. They are found in the northern regions of Alaska, Canada, Greenland, Norway, Russia, and the United States. Polar bears rely on sea ice for hunting, breeding, and traveling, and are skilled swimmers and divers. Their main diet consists of seals, but they may also feed on fish, walruses, and other marine mammals.
