Traitorous Fish Throw Friends to The Wolves

叛逆的鱼儿宁愿牺牲朋友来保全自己

If you're being chased by a hungry bear, you're more likely to escape if you have a friend running alongside you. That way, the bear might kill your friend instead of you. In this situation, you're not really running away from the bear. You're just trying to run faster than your friend. It could be worse. You could try to trip your friend up or even break their leg, except you're probably too decent to do that. But a South American fish has no qualms.

如果你被一只饥饿的熊追赶，在你有朋友在身边的情况下，你会更容易逃脱。这样一来，这只熊可能会杀了你的朋友，而不是你。在这种情况下，你并没有真正逃离这只熊。你只是试图比你的朋友跑得更快。这会让情况更糟。你可以试图绊倒你的朋友或打断他的腿，不过你可能太正直以至于不会那样做。但南美有一种鱼却并毫无顾忌。

At first glance, this small fish looks pretty innocuous, and many people in South Americakeep them as pets. However, they are a bit of a nuisance. "There's a big problem with fishentering hydroelectric power station machinery."says Robert Young of the University ofSalford in the UK. So a few years ago, Young and his fellows started investigating ways to deterthe fish from getting into the machinery. To their surprise, they discovered that the astyanaxbimaculatus turned on each other if a predator approached.

乍一看，这些身材娇小的鱼儿看起来并无伤害力，许多南美洲人都将其作为宠物来饲养。然而，它们也会有一点点让人讨厌。英国索尔福德大学的罗伯特·杨说“当鱼进入水力发电站设备中时，就会带来很大的问题。”所以几年前，杨和他的同事开始研究如何阻止鱼群进入设备。令他们吃惊的是，他们发现如果有捕食者接近时，这种大头丽脂鲤会自相残杀。

Small fish often protect themselves by swimming in large groups, making it hard for predatorsto target a specific fish. In theory, all animals that could become prey have an incentive toattack their fellows when the group is threatened. Young says other species might betray eachother in the same way, but perhaps nobody has managed to ob-serve this behaviour yet.考研大纲2016

小鱼通常会成群结队地在水中游泳来保护自己，这可以使捕食者很难瞄准某一个特定的鱼儿。但从理论上讲，当群体受到威胁时，所有可能成为牺牲者的动物都有袭击它们同伴的动机。杨说，其他的物种也可能会以同样的方式背叛对方，但也许是因为尚未有人观察到这种行为。
