settled in deserted structures on Kolyuchin Island, located in the Russian Arctic. Polar bears are the most massive bears globally, reaching lengths of up to nine feet and weighing as much as 1,300 pounds.
These bears maintain their enormous size primarily through a diet consisting largely of seals, and their fur, which appears white, is essential for them to navigate the Arctic with effective concealment. Polar bears possess a layer of short, dense fur underneath and a longer layer on top. This outer layer, referred to as guard hair, creates a fascinating optical effect that makes polar bears look white.
