The Piranha's Reputation
While near piranhas prefer to eat smaller fish, insects and mollusks, fable has it that when these tiny creatures assault, they can rip large portions of flesh from a human and have fifty-fifty attacked cows in the past. But Popular Science reports that it would take 300 to 500 piranhas to rip the flesh from a 180-pound human in five minutes. Some species of the fish are full vegetarians and merely feed on plants, basics and fruits.
Smithsonian Magazine has credited U.Due south. President Theodore Roosevelt with spreading the legend of piranhas' supposedly monstrous beliefs. Subsequently touring Due south America in 1913, he wrote, "They are the most ferocious fish in the world. Fifty-fifty the most formidable fish, the sharks or the barracudas, commonly set on things smaller than themselves. Just the piranhas habitually attack things much larger than themselves."
Roosevelt also reported watching piranhas devour an entire cow in mere minutes. All the same, the reason for their hunger has been debunked — sort of.
