Description
Theàpolar bearàUrsusàmaritimus is aàhypercarnivorousàbearàwhose native range lies largely within theàArctic Circle, encompassing theàArctic Ocean, its surrounding seas and surrounding land masses. It is a large bear, approximately the same size as theàomnivorousàKodiak bearàUrsus arctos middendorffi. A boar adult male weighs around 350ââ¬â700àkg 772ââ¬â1,543àlb,àwhile a sow adult female is about half that size. Although it is theàsister speciesàof theàbrown bear,àit has evolved to occupy a narroweràecological niche, with many body characteristics adapted for cold temperatures, for moving across snow, ice and open water, and for huntingàseals, which make up most of its diet.àAlthough most polar bears are born on land, they spend most of their time on the sea ice. Their scientific name means `maritimeàbear` and derives from this fact. Polar bears hunt their preferred food of seals from the edge ofàsea ice, often living off fat reserves when no sea ice is present. Because of their dependence on the sea ice, polar bears are classified asàmarine mammals.
