1/9/2023 0 Comments Polar bear![]() ![]() Some polar bears stay on permanently frozen sea ice in the Arctic Basin, but most live on the annual sea ice that forms around the Arctic Basin. They are not found in Antarctica (opens in new tab), where penguins (opens in new tab) live. Polar bears live on the ice-covered waters of the Arctic and countries around the Arctic Circle (opens in new tab), including Canada, Alaska in the U.S., Greenland (opens in new tab) (part of Denmark), Norway, Russia and occasionally Iceland, according to the International Union for Conservation of Nature (IUCN) (opens in new tab). Polar bears are heavier and taller on average, but individual Kodiak bears may be larger than average-size polar bears. The confusion is partly due to the way that "largest" is defined, because the answer varies depending on whether bears are measured by length, weight, or by the largest individual ever recorded, according to the Library of Congress (opens in new tab) in Washington, D.C. Some sources, such as the Alaska Department of Fish and Game, claim that Kodiak bears are the largest bears on Earth (opens in new tab). These brown bears can stand over 10 feet (3m) tall on their hind legs and weigh up to 1,500 pounds (680 kg), according to the Alaska Department of Fish and Game. Kodiak bears live on islands in the Kodiak Archipelago off southern Alaska, where they have been isolated from other brown bears for about 12,000 years, according to the Alaska Department of Fish and Game (opens in new tab). Polar bears are the biggest bear species, but Kodiak bears, a subspecies, or type of brown bear, can grow to about the same size as some polar bears. Polar bear skin is black and absorbs the heat of the sun, which helps keep the bears warm. Polar bears can also appear yellowish or even brown and gray, depending on the season and light conditions. Their white appearance enables the bears to blend in with their snow-covered, icy environment. ![]() Polar bear fur appears to be white but it's actually transparent the white appearance is due to visible light scattering and reflecting back off clear, hollow strands of hair, according to Polar Bears International. Size: 3.5 to 5 feet (1.5 m) tall at the shoulder (all fours) ![]()
