Polar Bear Adaptations

Polar Bear Adaptations


Polar bears have adapted in numerous ways. These polar bear adaptations allow the polar bear to thrive in the environment of the Arctic circle.



Polar bears have small and rounded ears. These ears are important because they help prevent water entering their ears which could then freeze and damage their ear drums. Also less body heat is lost out of the small ears.


Other adaptations of the polar bear include hollow fur that traps hair inside. This trapped air helps keep the polar bear floating in the water. This air also provides insulation for the polar bear.


Polar bears have long, stiff hair between the pads in their feet. These hairs help protect the polar bear from the cold as well as provide traction on the ice on which they walk. These hairs also help the polar bear swim in the cold icy water of the Arctic. These pads also help prevent the polar bear from slipping on the slippery ice. Their hair usually shakes free any water or ice that forms after they finish swimming.


Polar bears also dig their dens several meters deep below surface level. These deep dens help shelter the polar bear from the winds which sweep over the ice whenever there are strong gusts.


Polar bears have a thick layer of blubber under their skin. This layer of blubber can be up too 11 cm thick and this layer helps to insulate the polar bear from the Arctic cold. However this layer of blubber also means that overheating might occur. To prevent this overheating the polar bear moves slowly and rests often.


The light colour of the polar bears fur helps to camouflage them when they walking on the ice.


Polar bears are strong swimmers which have been known to pick up speeds of up too 10 kph. They have also been known to swim for 100 km. This enables the polar bear to better catch their prey.


Polar bears swim to cool down on warm days.
