Polar Bear



The polar bear is a carnivorous bear whose native range lies largely within the Arctic Circle ,encompassing the Arctic Ocean, its surrounding seas and surrounding land masses

A boar (adult male) weighs around 350–700 kg (772–1,543 lb),while a sow (adult female) is about half that size

Although most polar bears are born on land, they spend most of their time on the sea ice

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

Because of expected habitat loss caused byclimate change, the polar bear is classified as a vulnerable species  and at least three of the nineteen polar bear subpopulations are currently in decline.

However, at least two of the nineteen subpopulations are currently increasing, while another six are considered stable
