In the warm southwest United States rabbits are brown and have long ears. In Polar Regions rabbits are white and have shorter ears. But rabbits from Polar Regions have white fur. Because to protect from predators and mould to survive in cold environment.

Explanation:

Shortened ears and a thick, white coat are some of the physical features created by snow bunnies to survive in the hard, frozen tundra. The polar rabbits (hares) live in the cruel climate of the North American tundra.

These hares do not lie dormant, but survive a dangerous cold, adapting to various behavioural and physiological changes. They have thick coats and a low surface to volume ratio that accumulates body heat, which is most noticeable in their shortened ears.

Hares sometimes dig a shelter in the snow and crawl together to share the warmth. In winter, they have a beautiful white jacket that provides great camouflage on ice and snow.
