Arctic Hare (Lepus arcticus): Physical Adaptations for the Tundra

The Arctic hare is a master of cold-weather survival. Key physical traits:

• Size: 50–70 cm body length; 2.5–5.5 kg weight—larger than most rabbits.
• Ears: Long with black tips; relatively shorter than temperate hares to reduce heat loss.
• Fur: Summer: brownish-gray for tundra camouflage. Winter: thick, pure white for insulation and snow concealment. Molting is seasonal.
• Eyes: Large, brown, adapted for low-light Arctic conditions (long twilight periods).
• Body Shape: Stocky, compact, with short limbs to minimize surface-area-to-volume ratio.
• Feet: Broad, heavily furred soles act as snowshoes, distributing weight on soft snow.
• Tail: Short, white, inconspicuous.

These adaptations allow the Arctic hare to thrive in one of Earth's harshest environments, from Greenland to the Canadian Arctic Archipelago.
