Why is the polar bear white?

Polar bears are white because their white coat masks them perfectly in the snowy environment in which they live. The white coat is a good thermal insulator, which helps polar bears to stay warm in the cold arctic climate.

Polar bears live in areas with very low temperatures, reaching as low as -50 degrees celsius. Their white coat helps them to stay warm because it reflects the sun’s rays and keeps the heat inside their bodies. The white coat also helps polar bears to hunt, as it allows them to be almost invisible to other animals that are their prey.

Polar bears are also very well adapted to life in cold climates. They have thick layers of fat under their skin to help them retain heat and protect them from the cold. Their legs are also very thick and serve as excellent thermal insulators. Thanks to all these characteristics, polar bears can survive in the harsh conditions of the arctic.
