Malicious piran'i proved to be by the large cowards

In spite of ominous reputation, piran'i in reality not too are terrible. And even on the contrary, they themselves in all to fear. To this conclusion came the researchers of university St Andrews (Scotland) and institute Mamiraua (Brazil).

Previously scientists assumed that piran'i are collected by flocks in order to attack its victims. Now, after conducting the more in-depth research of the means of the life of sadly famous small fishes, scientists understood that piran'i are completely peaceful. They feed by small small fry, algae and insects, not on whom they will attack nor are gathered never into the flocks in order to be protected from the predators, such as river dolphins and caimans. Moreover, the greater the danger in them it threatens, the greater the flocks they form. The largest accumulations of piraniy are noted in the shallow sections of the Amazon, where it is too small place in order to be hidden from the predators.
