Piranha
Relationship with humans
Most piranha attacks on humans only result in minor injuries, typically to the feet or hands, but they are occasionally more serious and very rarely can be fatal. Near the city of Palmas in Brazil, 190 piranha attacks, all involving single bites to the feet, were reported in the first half of 2007 in an artificial lake, which appeared after the damming of the Tocantins River. In the state of São Paulo, a series of attacks in 2009 in the Tietê River resulted in 15 people with minor injuries. In 2011, another series of attacks at José de Freitas in the Brazilian state of Piauí resulted in 100 people being treated for bites to their toes or heels. On 25 December 2013, more than 70 bathers were attacked at Rosario in Argentina, causing injuries to their hands or feet. In 2011, a drunk 18-year-old man was attacked and killed in Rosario del Yata, Bolivia. In 2012, a five-year-old Brazilian girl was attacked and killed by a shoal of P. nattereri. In February 2015, a six-year-old girl died after being attacked by piranhas when her grandmother's boat capsized during a vacation in Brazil.
