問題詳情

v. The piranha is a much-maligned fish. Most people think that this is a deadly creature that swarms through rivers and creeks ofthe Amazon rainforest looking for victims to tear apart. And woe betide anyone unlucky enough to be in the same water as a shoal ofpiranhas. It takes only a few minutes for the vicious piranhas to reduce someone to a mere skeleton. The truth is that the piranha isreally a much more nuanced animal than the mindless killer depicted in the media. In fact, piranhas are a group made up ofapproximately twelve different species. Each piranha species occupies its own ecological niche. One type of piranha takes chunks outof the fins of other fish. Another type eats fruit falling from trees into the river. Each piranha species plays a unique role in theecology of the rainforest floodplains. So what should you do next time you hear someone talking about the “deadly piranha”?
