How Do Polar Bears Survive In The Arctic Environment?

They’re built for it! Polar bears love the arctic climate, where winter temperatures can plunge to -45º C (-50º F). Polar bears are insulated by two layers of fur that help keep them warm. They also have a thick fat layer. In addition, their compact ears and small tail also prevent heat loss. In fact, polar bears have more problems with overheating than they do from the cold—especially when they run.

Polar bear feet are furred and covered with small bumps called papillae to keep them from slipping on ice. Their sense of smell is powerful for detecting seals. And their powerful claws can haul out a 40-90 kg (150-200 lb) seal from the water for dinner.
