Adaption of an animal: Polar Bear

The Polar Bear has learned to adapt to the cold environment by having a thick layer of blubber (fat) that keeps them warm while swimming in cold water. The thick insulation of fat allows the polar bear to stay warm when the temperature gets to below 37 degrees Celsius. Being insolated is good on really cold days, but they tend to overheat often, so they walk slowly, swim, or rest to relieve some of the heat. They have learned to close their nostrils when underwater so they don’t run out of oxygen when the dive for prey, navigate ice floes, and search for help.
