国家地理 恐怖的吸血蝙蝠

Here are some happy vampire¹ bats. What's causing all this giddiness? A great, big, fat meal has arrived. You can practically hear these bats going "Oh, boy! Oh, boy!" Better yet, the victim is asleep. This is gonna be like, well, taking blood from a sleeping pig.

这里是一些心情很好的吸血蝙蝠。他们为什么如此雀跃呢？那是因为有大餐可以吃。我们仿佛都能听见这些蝙蝠在高呼着“哇，美食！美食！”更好的是，猎物正昏昏入睡。这就像从一头死猪身上取血一样简单。

The bats have heat sensors² in their noses. This thermal³ process lets us see what the bat sees. The bat wants to feed where the pig's skin glows white hot. Let the dining commence. Like two wildcatters fighting over a fresh oil strike, these bats battle over a particularly rich feeding spot. Four vampire bats, one sleeping pig. Why doesn't the pig wake up? Because the bat's teeth are razor-sharp and cut painlessly. The bats can sip⁴ to their hearts' content with the pig none the wiser. The bat's saliva⁵ actually prevents the blood from clotting⁶. As the bat sips⁷, the blood runs up a glue on the underside of its tongue. Mother Nature thinks out everything. These vampire bats can feast for a full half hour, drinking half their weight in blood.

蝙蝠的鼻子有热感受器。这个热过程可以让我们看到蝙蝠能看到的一切。这只蝙蝠想要吸食猪皮上白热的部分。那就开动吧！就像采油者会为一个刚出土的油矿争夺一样，蝙蝠也会为美食而战。现在有4只蝙蝠，1只沉睡的猪。猪为什么不会醒呢？这是因为蝙蝠的牙齿很锋利，即便咬到猪，猪也不会觉得痛。蝙蝠可以撒欢儿地吃，而猪却浑然不知。蝙蝠的唾液能防止血液凝结。蝙蝠吸食过程中，血液会像胶水一样贴在其舌头下面。造物主鬼斧神工。蝙蝠可以在半小时的时间里饱餐一顿，吸食掉这只猪一半的血液。

In a month of feedings, five vampire bats can guzzle⁸ almost a gallon of pig's blood. In this case, it's the bats making a pig of themselves, not the pig.

一个月的时间里，5只蝙蝠的食量就差不多是一加仑的猪血。这样看来，蝙蝠才是能吃的猪。
