These towering beasts look like they need a comfy mattress but shut-eye's not a giraffe's biggest concern. 长得像塔一样的长颈鹿看起来很需要一张舒服的床垫，不过睡觉不是长颈鹿要操心的大事。 Just looking at these slumbering giraffes is enough to give you a crick in the neck - which is why the world's tallest animals don't often stop for a snooze. 看着这些睡觉的长颈鹿你都会觉得脖子累，这就是为什么这种世界上最高的动物通常不会随便停下打个盹儿。 Despite their height, giraffes actually have the shortest sleep requirement of all mammals, surviving on an average of half an hour a day. 虽然长颈鹿长这么高，但是它们是所有哺乳动物里面睡得最少的，平均每天睡半个小时就够了。 When they do settle to sleep, it's for minutes at a time, because of the risks to their wellbeing in the wild. 当真的要睡觉的时候，它们一次只睡几分钟，因为在野外可不太安全。 In captivity, the giraffe sleeps intermittently around 4.6 hours per day, mostly at night. It usually sleeps lying down, however, standing sleeps have been recorded, particularly in older individuals. 笼子里的长颈鹿每天大约会断断续续地睡4.6小时，大部分时间是在晚上。它们一般会躺着睡，不过记录中也有站着睡的，特别是那些年纪大的。 |
