As they are so tall—males can grow up to 18 feet, giraffes actually have the shortest sleep requirement of all mamma1s哺乳动物), with an average(平均) of half an hour a day. When they sleep, they seldom lie down and sleep for minutes at a time, since it's difficult for them to get up again and it's dangerous in the wild.
