Polar Bears In Natural Selection

(Keep Scrolling For More Information)What do Polar Bears eat to survive?Polar bears are carnivores who eat seals(their favorite meal of the day) and once in a while carcusses(like dead whales or walrus). “When other food is unavailable, polar bears will eat just about any animal they can get, including reindeer, small rodents, seabirds, waterfowl, fish, eggs, vegetation (including kelp), berries, and human garbage” (Sea World) in order to survive.

(Keep Scrolling For More Info.)Why do Polar bears have blue tongues?“Polar bears do not sweat through their skin, and their paws are also unsuitable for heat regulation, being thickly callused to prevent the bears from cutting themselves on sharp ice edges. The bears therefor regulate heat, like dogs, by panting. The tongue is then blue as a result of high blood circulation” (Cetti).

Polar Bears live in the North Pole, by the Atlantic Ocean.
