英语翻译
Like a (pit bull),(piranhas) will tear the flesh from your bones.Also,like a (pit bull),they bark,kind of.Scientists had known that (piranha) barked when you pick em up ,carfully of course,but they hadnt known what these sounds are for.So researchers have examined how vocalizations might (correspond) with behavior.They dropped a microphone into (a piranha tank) that at different times held three groups of ten fish.They then placed a (mussel in) to see how the fish competed for food.When the fish faced off,they produced that percussive bark.When they circled one another,they (made) a softer (thud) sound.A teeth (gnashing) indicated that the(a piranah) was getting pretty ticked off as they chased the competitor.The first two sounds are produced by muscles contracting around the fish's swim bladder.The findings are in the journals of experimental biology.The researchers are now interested in whether the () vocalize during mating.But they'll have to (travel) to Brazil to study this in the wild.It turns out that when they come to mating in (captivity),(piranhas) say no (tanks).
主要是最后那个 SAY NO

首先说明下情况,这篇短文没有错误（个别小错误不算错吧）,就是一篇科普类说明文.跟四六级挺像的,下面尝试翻译：
水虎鱼可以像斗牛犬那样把你身上的肉撕破,当然,他们有时候也会发出类似犬吠的声音,这点也像斗牛犬.科学家们已经发现,拿起他们的时候他们会发出声音,（当然,拿的时候要小心翼翼）但是不知道这些声音有什么用处.科学家把麦克风丢进装有三群水虎鱼的水族箱里,每群有十只.然后把一直蚌丢进去,看他们会以怎样的方式争夺食物.短兵相接时,他们会发出类似敲击的声响,当一起绕着圈游动时,发出较为柔和的砰状声.当他们咬紧牙关追逐竞争者时,表面他们被惹火了.前两次声音是从鱼漂周围的肌肉发出来的.这些发现被记录在实验生物学日志里面.研究者现在比较感兴趣的是他们交配时会发出什么样的声音.但是他们要到巴西才能研究野生环境下的情况.因为实验表明,在被囚禁的水族馆里交配时,他们不发出声音.
说明：say no tanks是比较生动的用法,意思就是我们不要呆在tank里面.根据上下文,意思显而易见.
看在翻译这么多字的情况下,给分吧,手都累麻了.

从哪搞来的,有没写错啊?

说：不用谢。
你这篇英语原文比较乱 啊
