Arctic hare

The Arctic hare is a fluffy, cold-loving mammal built for life in the frozen tundra. With thick fur and compact features to conserve heat, it thrives where most animals would freeze. These hares can sprint as fast as a car in city traffic when darting across the snow.

• Its fur coat and body fat keep it warm in temperatures far below freezing.
• Arctic hares sometimes gather in large groups, huddling for warmth in the snow.
• They can reach speeds of 60 km/h (40 mph) when running across the tundra.
