Polar Bear Day!

*
  • The babies are much smaller than human babies when they're born.  They are the size of a rat and weigh little more than a pound.  They can grow to full man size in a year if they have lots of food.
*
  •  Male polar bears may grow 10 feet tall and weigh over 1400 pounds.  Females reach seven feet and weigh 650 pounds.  In the wild polar bears live up to age 25.

  • Despite what we think, a polar bear's fur is not white.  Each hair is clear hollow tube.  Polar bears look white because each hollow hair reflects the light. On sunny days, it traps the sun's infrared heat and keeps the bear warm at 98 degrees F (when they're resting).
*
  •  Polar bear fur is oily and water repellent. The hairs don't mat when wet, allowing the polar bears to easily shake free of water and any ice that may form after swimming.
