Polar Bear vs. Brown Bear: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on December 22, 2023
Polar Bear is a large, carnivorous bear adapted to Arctic life with white fur. Brown Bear is a large bear species with varying fur color, found in various habitats including forests.

Key Differences

Polar bears are native to the Arctic region, uniquely adapted to cold climates with their thick, white fur and layer of blubber for insulation. Brown bears, also known as grizzly bears in North America, are found in diverse habitats including forests, mountains, and even coastal areas, and have brownish fur which can vary in shade.
