This is what happens when group of piranhas are thrown big chunks of meat are thrown into the water.
A group of Brazilian fisherman decided to film how quickly the notoriously violent fish turn the water into a whirlpool, attacking with terrifying speed and intensity.
Piranhas are freshwater, omnivorous fish which are native to South American rivers.
Known for their razor-sharp teeth and taste for meat of all kind, the fish are feared the world over.
Earlier this year, a six-year-old girl died in Brazil's Maicuru River this year after being attacked by piranhas when her grandmother's canoe capsized in a storm. There were four other children in the boat at the time who survived the accident, the BBC reports.
Although piranha attacks are rare they can be incredibly dangerous and fatal in some cases.
