What is the gestation period of the polar bear?



  1. 0 Votes

    The gestation period of a polar bear is approximately 8 months long.  These 8 months include a period of delayed implantation when the fertilized egg is not attached to the female polar bears’ uterine wall for about four months.  This delayed implantation allows the cubs to be born at the most ideal time of year. Polar bears typically have two cubs once every three years.
