【英语时差8,16】凶猛的鱼类2

 The four species of piranha that are carnivorous, however, certainly earn their reputation as fierce fish. These meat-eaters have powerful jaws¹ and razor sharp teeth that fit together like cutting shears² when they bite. Piranha travel and hunt in schools of about twenty fish, and can engage in impressive feeding frenzies³ when aroused by blood or commotion⁴ in the water. Carnivorous piranha will eat anything from other fish to large mammals such as cows and even jaguars⁵ that wander too far into the water. Although flesh-eating piranhas sometimes attack people, humans tend to have the last laugh. In South America and elsewhere piranha are considered fine eating fish. It’s safe to say that many more piranha are eaten by people than the other way around.
