Polar Bears are one of my favorite animals and the adaptations they have made over time are simply amazing to me. A couple of ways they have adapted to their environment are that they

- have long stiff hair between their feet to protect against the cold and provide friction against the icy environment in which they live
- have hollow fur which traps air inside so they float when they are in the water
- dig dens that are several yards deep so they are able to raise young and survive through the harsh environment of the Arctic
- have blubber that allows them to retain heat
- have become strong swimmers being able to swim around 7 mph
