Polar bears are classified as marine mammals because they spend most of their lives on the ocean ice of the Arctic Ocean. they need a thick layer of body fat and a water-repellant coat that insulates them from the cold air and water. Considered talented swimmers, they will sustain a pace of six miles per hour by paddling with their front paws and holding their hind legs flat sort of a rudder.

Polar bears spend over 50% of their time looking for food. An ice bear might catch just one or two out of ten seals it hunts, counting on the time of year and other variables. Their diet mainly consists of ringed and bearded seals because they have large amounts of fat to survive.

Scientists have divided the entire ice bear population into 19 units or subpopulations. Of those, the newest data from the IUCN ice bear Specialist Group show that one subpopulation is in decline (Southern Beaufort Sea) which there’s a high estimated risk of future decline thanks to global climate change and data deficiency.

Because of the ongoing and potential loss of their sea ice habitat resulting from global climate change, polar bears were listed as a threatened species within the US under the species Act in May 2008.
