Their white coat is actually made of hollow hairs that reflects the sunlight, producing a white or yellow colour camouflaging in their habitat. Polar bears mate between April and May. Cubs are born about every three years, generally in litters of two.At birth, the cubs weigh approximately one and a half pounds.Males can grow to weigh as much as 1,000 pounds and reach 11 feet in length. Polar bears are carnivores, feeding primarily on Arctic ringed seals. Their partially webbed paws allow them/ to swim, at a pace of six miles per hour, for up to 60 miles without rest. They live and hunt on frozen ice floes during winter months, and survive on berries and stored fat when the short summer thaw forces them onto land, rendering seals inaccessible. The causes for the decreasing of population is that there are lesser sea ice, the hunting and capture for public display , climate change , environmental contaminants and chemical pollutants.
