Based on the images, what other adaptations do these animals display?

Polar Bears

Polar bears have white fur which helps aid in camouflaging against the snow. They also have small rounded ears that act as a shield letting no water in to freeze ear drums and reduce heat loss.

Black Bears

Black bears absorb heat through their black skin. Their thick fur and fat act as an insulation and their large bodies reduce heat loss.

They both use their large claws and teeth to catch prey and provide for themselves
