Shortened ears and thick, white fur are among the physical traits that arctic hares have adapted to survive in the harsh, frozen tundra.

The arctic hare lives in the harsh environment of the North American tundra. These hares do not hibernate, but survive the dangerous cold with a number of behavioral and physiological adaptations. They sport thick fur and enjoy a low surface area to volume ratio that conserves body heat, most evident in their shortened ears. These hares sometimes dig shelters in snow and huddle together to share warmth.

Females give birth to one litter per year, in spring or early summer. Two to eight young hares grow quickly and by September resemble their parents. They will be ready to breed the following year.
