在非洲草原上,有一种不起眼的动物叫作吸血蝙蝠。它身体极小,却是野马的天敌。它在攻击野马时,常附在马腿上,用锋利的牙齿极敏捷地刺破野马的腿,然后用尖尖的嘴吸血。无论野马怎么蹦跳、狂奔,都无法驱逐这种蝙蝠,它可以从容地吸附在野马身上,落在野马头上,直到吸饱吸足,才满意地飞去。而野马常常在暴怒、狂奔、流血中无可奈何地死去。动物学家们在分析这一问题时,一致认为吸血蝙蝠所吸的血量是微不足道的,远不会让野马死去,野马的死亡实则是它暴怒的习性和狂奔所致。
On the African steppe, there is a humble animal called a vampire bat. It is a very small body but it is a natural enemy of the Mustang. It attaches itself to the horse’s legs when attacking a wild horse, piercing its legs with sharp teeth, and then sucking blood with a pointed mouth. No matter how the wild horse jump, bolted, can not expel the bat, it can be calmly adsorbed on the wild horse body, fell on the wild horse head, until fully absorbed enough to fly satisfiedly. The wild horses often fury, bolted, bleeding helpless to die. Zoologists in analyzing this issue, agreed that the vampire bat sucked blood is negligible, far from let the wild horse died, the wild horse’s death is actually the habit of its rage and mad rush.
