What makes piranhas aggressive?
Part of piranhas’ fierce reputation stems from the fact that they often swim in packs or shoals. Red-bellied piranhas are particularly known as pack hunters. Though it might seem an advantageous hunting technique—more fish could theoretically take down a larger foe—the behavior actually stems from fear.

Probably not. Piranhas are neither carnivorous nor aggressive man-eaters. We’re pretty sure that no one has ever been eaten alive by piranhas, even if a few attacks have been reported.
