Polar Bears

The Arctic is tough. Polar bears are tougher. We are home to males ‘Baffin’ and ‘Siku’.

The world’s largest bear in a delicate ecosystem

Ice and snow are no match for polar bears, who are adapted to the extreme cold of the tundra. Between their two layers of fur and thick layer of blubber, a polar bear experiences almost no heat loss, and can even overheat when running across its Arctic landscape. Their enormous size doesn’t make them less agile – they are incredibly strong swimmers, able to swim for hours at a time.
