The polar bear, Ursus maritimus, is the world's largest bear. It has black skin with an outer layer of transparent fur that looks white. It lives in the Arctic where it eats mostly seals, functioning as a top predator in the Arctic Ocean's food web and considered a marine mammal even though it spends most of its time out of the actual water.
While polar bears are not yet endangered, global warming is having a drastic effect on their Arctic habitat. Polar bears rely on the presence of sea ice from which they hunt for their main prey of seals. Additionally, modern human encroachment into the Arctic is having an impact, for example oil development.
