Polar Bear

The Polar Bear (Ursus maritimus) is a carnivorous bear native largely within the Arctic Circle encompassing the Arctic Ocean, its surrounding seas and surrounding land masses. It is the world's largest bear. A boar (adult male) weighs around 350–700 kg (770–1,500 lb.), while a sow (adult female) is about half that size. Although it is closely related to the brown bear its body adapts to cold temperature's, for moving across snow, ice, and open water, and for hunting the seals which make up most of its diet. Although most polar bears are born on land, they spend most of their time at sea. 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. Polar Bears rarely live longer than 25 years old but the oldest one recorded lived to 32 years old. When a female Polar Bear gets pregnant she put on 200kg, so if you think you are "fat" think again. Polar Bear mothers look after their cubs for 2 and a half years. Adult males occasionally kill and eat the cubs :( . The longest recorded swim for a Polar Bear was 354km. Polar Bears are becoming endangered at an alarming rate and we should protect these beautiful creatures.
