I am sure most of you have heard of piranha, and if you don't, piranha is a kind of fish that can rip an animal or maybe even human to bone in seconds. They always stay in group, and most people don't know that, actually they are fearful creatures, forming a shoal for self defence, most piranhas don't eat any meat at all. Of the 500 species, a majority are vegetarian - living mainly on fruit, nuts and seeds which fall into the water.
The part of ripping to the bone was exaggerated, that only happen if it is a group of hungry piranha, and people can actually swim with piranha unless you are bleeding. not sure about the bleeding part though, i assume the blood will attract the fish:P
Although it was exaggerated, piranha was not exactly a safe fish either,care still must be taken^^
The myth of the aggressive piranha seems to have been brought into the western world, at least in part, by U.S. President Theodore Roosevelt, who in 1914 described witnessing a shoal stripping the flesh from a cow in minutes when he visited Brazil. But he was unaware that the show had been set up to entertain tourists and that the captive fish had been kept hungry for days so they would go into a feeding frenzy.
