The Polar Bear (Ursus maritimus) is a bear native to the Arctic Ocean and its surrounding seas. Being the world’s largest carnivore found on land, together with the Kodiak Bear they constitute the largest members of the Bear family. The polar bear is often regarded as a marine mammal because it spends many months of the year at sea. Polar Bears’ preferred habitat is the annual sea ice covering the waters over the continental shelf and the Arctic inter-island archipelagos. These areas, known as the “Arctic ring of life”, have high biological productivity in comparison to the deep waters of the high Arctic. The polar bear tends to frequent areas where sea ice meets water, such as polynyas and leads (temporary stretches of open water in Arctic ice), to hunt the seals that make up most of its diet. Polar Bears are therefore found primarily along the perimeter of the polar ice pack.
