Strong sense of smell. Run up to 40 mph. Wide front paws with webbed toes. Paddle with front feet, steer with hind feet. Paw pads have rough surfaces to help polar bears from slipping on the ice. 3. Polar Bears Have: Small heads. Powerful jaws. Black noses. Black tongues. Small flat tails. 42 teeth. 4. All About Polar Bears Polar bears have two types of fur. Thick, woolly fur close to the skin. Hollow guard hairs stick up andprotect the bears from getting wet.These guard hairs are like drinkingstraws, clear-colored (not white). The white-looking coatcamouflages them in the snow andice. Under the fur, polar bears haveblack skin. Have a thick layer of fat (up to 4inches thick) under the skin. 5. Where Can You Find Polar Bears? The polar bear or the sea/ice bearare the worlds largest landpredators. Can be found in the artic, theU.S. (Alaska), Canada, Russia,Denmark (Greenland), andNorway.. Each of these countries eitherbanned hunting or establishedrules for how many polar bearsyou can hunt. Today, 25,000 to 40,000 polarbears roam the arctic. 6. Polar Bears and Their Families Pregnant females polar bears (calledsows) build snow dens. Give birth to 1-3 cubs. Cubs are born 12 to 14 inches long andweigh little more than a pound.They areblind, toothless, and covered with short,soft fur. Completely dependent on mother forwarmth and food. Cubs normally stay with the mother forthe first two years. Cubs are much smaller than humanbabies when born. Male polar bears (called boars) areactive all year. 7. How Do Polar Bears Hunt? In cold weather, polar bears, except pregnant females, head outonto 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 tokeep from breaking the ice and falling in. Polar bears spend as much time on ice as they do on land. 8. What Polar Bears Eat Polar bears arecarnivores (meat-eaters). Hunt and catch their preyin the water. Eat mostly seals. Stomach can hold up to150 pounds. Polar bears dont drinkwater. 9. 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, circlearound the food, and then softly offer a nose-to-nose greeting. When a polar bear wants to play with another polar bear , he wags hishead from side to side. An adult bear will stand on his hind legs, chin lowered to chest and frontpaws 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. 10. Sounds of a Polar Bear 11.
