The rabbit with the longest leg in the world is the arctic rabbit (scientific name: Lepus arcticus), which is a mammal of the genus Rabbinidae. Arctic rabbits are huge, with bigger and longer heads, smaller ears, long legs and very strong and flexible limbs. Their backs are light gray in summer and white in winter.

Arctic rabbits are gregarious animals with sensitive noses and ears. They are not shy and timid, and are easy to tame. They mainly feed on moss, plants, roots and other foods, and occasionally eat meat. They give birth once a year, and each litter can give birth to 2-5 cubs. They live in the cold regions of northern North America and are distributed in Canada and Greenland.

Arctic rabbits have been listed in the Red List of Endangered Species of IUCN IUCN)2008. Arctic rabbits are generally 55-7 1 cm in length and 4-5.5 kg in weight. Huge, about the size of a fox. The head is bigger and longer than the average rabbit. Small ears and long legs, but the limbs are very powerful and flexible.

Arctic rabbits have wide feet and thick hair, which can not only adapt to the cold snow, but also facilitate running and jumping on the snow, and can also effectively reduce the pressure on their feet without causing too much subsidence when moving, so they are called snowshoe rabbits in North America. The tail is of medium length, and the hair at the root is unkempt and mixed with long hair.
