  1. The Polar Bear Life Cycle By: SanjanaRamchandran

  2. Birth • Cubs are born from Nov.–Jan. in a den. They stay there with their mother until spring. • Weight: About 1 lb. • Polar bear cubs are so tiny at birth that they can fit in the palm of your hand!!! • They’re very helpless and are born with their eyes closed. 

  3. Polar Bear Cubs: • There are usually 2 cubs per litter • Mother polar bears are VERY protective of their young • Open their eyes within a month • Start walking at two mos. • Start eating solid food at 3-4 mos. • Learn to hunt from watching their mom • I was very sad to find out that: when cubs are about 30 mos. old, an adult male may start following the mom. At this time, the mom or the male will chase away the cubs. 

  4. Adult Polar Bears: • Polar bears start mating every other year in mid-summer. • After that, they’re on their own in the wild.  • They mostly eat seals, although they can also eat fish, seabirds, even reindeer! • If they’re desperate in the summer for food, they may eat berries and plants! • After that, they mate, reproduce, and the cycle starts all over again!
