A video of an Ecuadorian man using a piranha as a pair of scissors has gone viral on YouTube. Taken in Cuyabeno Rainforest, Ecuador, the clip shows the man holding one of the deadly fish tightly in one hand. As the fish flaps its tail, unable to escape, he slowly lowers a twig into its mouth full of sharp teeth. The end of the stick is cut away in a flash, to the shock of onlookers heard gasping behind the camera. The fish is seen continuing to snap its jaw even after the stick has been taken away.
