are polar bears losing their habitat
Their scientific name means maritime bear, and derives from this fact. Polar bears hunt their preferred food of seals from the edge of sea ice, often living off fat reserves when no sea ice is present. Because of their dependence on the sea ice, polar bears are classified as marine mammals. The only other bear of a similar size to the polar bear is the Kodiak bear, which is a subspecies of brown bear. Adult male polar bears weigh 350–700 kg (772–1,543 lb) and measure 2.4–3 metres (7 ft 10 in–9 ft 10 in) in total length. Unlike other bear species, polar bears are almost exclusively meat eaters (carnivorous). They mainly eat ringed seals, but also bearded seals. They also eat walruses, other species of seals and whale carcasses. The polar bear (Ursus maritimus) is a carnivorous bear whose native range lies largely within the Arctic Circle, encompassing the Arctic Ocean, its surrounding seas and surrounding land masses. Polar bears prefer the ice packs to other parts of their habitat because it allows them to remain in close contact with their main food source. Seals. Polar bears will remain in this ice pack habitat all year. They prefer the sea ice over all other places. When summer comes, and the polar regions warm up, the polar bears will travel many miles to remain on the ice, near their food source, seals. Because of expected habitat loss caused by climate change, the polar bear is classified as a vulnerable species, and at least three of the nineteen polar bear subpopulations are currently in decline. Many of the polar bear's physical adaptations help maintain body heat and deal with their icy habitat: The outer layer of fur is hollow and reflects light giving the fur a white color. The white fur helps the bear remain camouflaged in icy and snowy habitat. Polar bears have adapted to be able to live in the water and on land. Unlike other bear species, the polar bear are excellent swimmers, and have been spotted more than 100 miles away from land or ice. The polar bear habitat is that of the entire Arctic region. They can be found the cold and at times unforgiving land. Polar bears can be found swimming in the frigid oceans waters, or adrift on ice. The polar bears main habitat is on offshore pack ice, and along costs and island of the Arctic region. Over 40 per cent of all polar bears living today live in Northern Canada, on pack ice and along the shores of the many island there. The polar bear is the apex predator within its range, and is a keystone species for the Arctic. Several animal species, particularly Arctic foxes (Vulpes lagopus) and glaucous gulls (Larus hyperboreus), routinely scavenge polar bear kills. 1 The white fur helps the bear remain camouflaged in icy and snowy habitat. 2  The skin is black under the fur; this black is evident only on the nose.  The footpads of a polar bears’ paws have a kind of “non-slip” surface allowing them to get traction on slippery ice.
