STRUCTURAL AND
BEHAVIORALADAPTATIONS
OF THEPOLAR BEAR
STRUCTURAL ADAPTATIONS:
Large paws
Black skin
blubber
Small ears
Fuzzy undercoat
A polar bear’s paw is about onefoot across. This enables the bear to walk in deep snow andTo swim in water.

keep the bear warm.
Underneath all that fur, a polarbear’s skin is black. Black skin helps absorb heat from the sun.
A thick fuzzy undercoat of furhelps keep a polar bear warm.
