　　The major difference between a rabbit and a hare is that the young of a hare are born open­eyed and furred.The rabbits’ young are born naked and with closed eyes.Hare are able to leave the nest soon after they are born but rabbits don’t even open their eyes for 7～10 days.Some people say that the length of the ears is part of the difference but the Arctic hare have short ears while hare outside of Arctic areas have long ears.

　　The Arctic hare look a lot different from the rabbits and the hare that you see anywhere outside of the Arctic.In the summertime the Arctic hare are brown with black flecks.This helps to camouflage it during the growing season.When the weather starts to change，the Arctic hare start to change too.So that during the winter its coat is completely white.This change helps to protect it during the winter.

　　The ears of an Arctic hare are so small to help keep the hare warm during the cold winters on the tundra(冻原)．The small ears do not have a lot of area to have the blood vessels exposed to the cold so more heat is kept down in the body to help the hare stay warm.

　　The Arctic hare have the world’s smallest “Big Foot”．The feet of an Arctic hare are huge compared to other rabbits.Having big feet is like having snowshoes.They help them to stay on top of the snow.If they could not do this，they wouldn’t be able to get away from their predators(掠食动物)．
