Living in the Arctic, the polar bear faces many challenges. One of the many challenges is a shrinking habitat. We humans have greatly contributed to the shrinking of the sea ice, which makes finding food harder for the polar bears. In a way, polar bears face loss of habitat space and food. There are not many animals that will feast on the polar bears, so they have no need to fear predators. As we humans slowly encroach on the polar bear habitat, we also pollut parts of their environment. Information and Media Sources: Survival Adaptations: Polar bears are normally very solitary, and that can help them avoid fighting each other. In certain scenarios, the polar bear would rather escape than fight. As young cubs, polar bears play-fight. Play-fighting while they're young helps them prepare for competition during mating season.
polar bears are considered to be marine mammals. A polar bear's front paws propel them through the water dog-paddle style. The hind feet and legs are held flat and are used as rudders. A thick layer of fat, up to 11 cm (4.3 in.) thick, keeps the polar bear warm while swimming in cold water. Polar bears can obtain a swimming speed of 10 kph (6.2 mph). A polar bear's nostrils close when under water.
