•

Polar bears have two types of fur.
Thick, woolly fur close to the skin.
Hollow guard hairs stick up and
protect the bears from getting wet.
These guard hairs are like drinking
straws, clear-colored (not white).
The white-looking coat
camouflages them in the snow and
ice.
Under the fur, polar bears have
black skin.
Have a thick layer of fat (up to 4
inches thick) under the skin.

weigh little more than a pound.They are
blind, toothless, and covered with short,
soft fur.
Completely dependent on mother for
warmth and food.

the first two years.
Cubs are much smaller than human
babies when born.
Male polar bears (called boars) are
active all year.
How Do Polar Bears Hunt?
• In cold weather, polar bears, except pregnant females, head out
onto the ice to hunt seals.
• Have been spotted hundreds of miles from shore.
• When the ice is very thin, polar bears crawl on their bellies to
keep from breaking the ice and falling in.
• Polar bears spend as much time on ice as they do on land.

carnivores (meat-eaters).

How Polar Bears Communicate
With Each Other?
•
•
•
•
•
•
•
•
Use body language and sounds.
A deep growl gives a warning to other bears.
Growls are commonly used to defend their food source.
To beg food from another bear, polar bears will approach slowly, circle
around the food, and then softly offer a nose-to-nose greeting.
When a polar bear wants to play with another polar bear , he wags his
head from side to side.
An adult bear will stand on his hind legs, chin lowered to chest and front
paws hanging by his side.
Angry polar bears make loud roars and growls.
Mother bears scold their cubs with a low growl or a soft cuff.
