Polar bear Screensaver

The free animal screensaver, Polar bear, contains 24 images of Polar bears. The polar bear (Ursus maritimus), a bear native to the Arctic, is the apex predator within its range. Its thick blubber and fur insulate it against the cold.
Its fur is hollow and translucent but usually appears as white or cream coloured, thus providing the animal with effective camouflage. Its skin is actually black in color, however. The bear has a short tail and small ears that help reduce heat loss, as well as a relatively small head and long, tapered body to streamline it for swimming.
