Killer Fish - Piranha

A piranha or piraña (/pᵻˈrɑːnjə/, /pᵻˈrænjə/, or /pᵻˈrɑːnə/; Portuguese: [piˈɾɐ̃ɲɐ], Spanish: [piˈɾaɲa]) is a member of family Characidae in order Characiformes, an omnivorous freshwater fish that inhabits South American rivers. In Venezuela, they are called caribes. They are known for their sharp teeth and powerful jaws. Piranhas have a reputation as ferocious predators that hunt their prey in schools. Various stories exist about piranhas, such as how they can dilacerate a human body or cattle in seconds. These legends refer specifically to the red-bellied piranha. A common falsehood is that they can be attracted by blood and are exclusively carnivores. A Brazilian legend called "piranha cattle" states that they sweep the rivers at high speed and attack the first of the cattle entering the water, allowing the rest of the group to traverse the river. These legends were dismissed through research by Hélder Queiroz and Anne Magurran and published in Biology Letters.Nevertheless, a study in Suriname found that piranhas may occasionally attack humans, particularly when water levels are low.
