The polar bear is a large bear classified as a marine mammal because it spends most of its live on the sea ice of the Arctic Ocean. Polar bears have a thick layer of body fat and a water-repellant coat that insulates them from the cold air and water. Their fur isn’t actually white, it just looks that way. Each hair is pigment-free and transparent and reflects visible light. Their diet mainly consists of seals because they need large amounts of fat to survive. Their numbers are in decline because of ongoing loss of their sea ice habitat resulting from climate change, and they are listed as a Vulnerable species.
