According to Outdoor Life and the life book of world records, the largest polar bear ever recorded was 2,210 pounds and 11 feet in height. The polar bear was recorded after being shot in Kotzebue Sound, Alaska in 1960. The carcass was displayed at the Seattle World's Fair in 1962.
Adult male polar bears generally weigh between 775 and 1,200 pounds. There are some exceptions to male polar bears weighing more than 1,200 pounds such as the one recorded at 2,210 pounds. The Portland Zoo has a male polar bear in their habitat that weighs in at a little over 1,500 pounds. This mammoth bear is close to 11 feet in height. Female polar bears tend to weigh 330 to 650 pounds. Many females will weigh close to 600 pounds when it is time to go in the den for winter because they are getting ready to gestate and give birth to bear cubs in the spring. Females usually have two cubs, but singles and triplets can occur. It will always depend on the mother's health at the time of conception. Cubs are with their mothers for two to two and a half years. During this time the mother is not actively pursuing any male relations. In fact, until the cubs are two to two and a half, the female bear will not be able to bear more cubs because she is concentrating on the survival of her cubs meaning their bodies are unable to handle a pregnancy.
Polar bears can cover 50 to 200 meters in one day using sea ice. Polar bears tend to move with the seals, since that is their food source. In summer they will travel to where the seals may be on land. They will survive trying to keep close to shore, but some have taken ice flows out great distances to catch prey.
