With the reputation of being a dangerous fish, along with their aggression and razor sharp teeth, people often wonder if the Piranha has another deadly trick up its sleeve.
So, are Piranhas Poisonous? No, not at all. They are not poisonous in any sense of the word. They do emit a poison as a natural defense like Cobra snakes, nor are they poisonous to eat. The Piranha is consumed as a food source by millions who rely on the Amazon river for their livelihood.
The Piranha Danger
The Piranha are considered a dangerous fish. The belief normally stems from movies or media reporting, both of which have exaggerated the danger posed by the fish.
They are actually a rather shy and timid fish in their natural habitat, who hide amongst the plant matter in order to evade their ever present predators, like the caiman, river dolphins and birds.
They danger from Piranha usually stems from extreme hunger during the dry season and the threatening of their breeding nests. Bites are often quick, but not fatal to humans. Humans normally receive ‘nips’ on fingers and toes if a Piranha is threatened. The fabled frenzy on humans doesn’t happen, and bodies found in the Amazon with Piranha bites are suspected to have been bitten post death. They are primarily scavengers.
They are certainly not dangerous as an emitter of poison. Piranha have no ability to chemically attack prey.
