What Eats It?
Other polar bears and humans prey on the polar bear.
Polar bears are solitary animals. They live and hunt alone except for mating pairs or a mother with cubs. When there is a large food supply they will tolerate other bears nearby.
Females begin breeding at about four years of age, males are usually older; mating occurs in April, May and June. Delayed implantation of the fertilized ovum takes place until the bear has gained enough weight to survive hibernation as well as giving birth and caring for cubs. In December or January a litter of one to three blind, hairless cubs weighing one pound (450 g) are born. They remain denned with their mother until March or April when they weigh about 20 pounds (9 kg). The cubs stay with their mother for two to three years receiving hunting lessons and protection. Lifespan in the wild is 20-25 years and in captivity 25-30 years.
