Arctic Hare is not a little white rabbit, the latter was domesticated from the Oryx rabbit, which is native to Europe. Among wild rabbits, only Arctic Hare is naturally white, because only in this way can they hide themselves in the "winter of food scarcity" in the eyes of natural enemies. In winter, the Arctic Hare in groups will huddle on rocky beaches or snow to keep warm, while the solitary individual will dig a snow hole to escape the cold wind. They have their necks shortened, their heads as close to their bodies as possible, and their legs as if they don't exist at all. In fact, Arctic Hare's legs are about the same length as the spine, but when perched, it folds into a lump with the body.
