Study Notes
- The polar bear is the largest carnivore and top predator in the Arctic, relying on sea ice in the Arctic Ocean to survive.
- There are approximately 26,000 polar bears living in the Arctic region across Canada, Greenland, Norway, Russia, and Alaska.
- Polar bears have evolved to thrive in harsh climates with adaptations like thick fat, two layers of fur, and small ears and tail to conserve heat.
- Despite their insulation, polar bears can overheat when they run due to their physical adaptations.
- Climate change has led to longer summer months, delaying sea ice formation and causing polar bears to go longer periods without food, impacting their survival.
