BUENOS AIRES, Argentina (January 18, 2014) An attack by a school of carnivorous fish injured at least 10 people as they bathed in the Parana River in Rosario, Argentina, about 190 miles northeast of Buenos Aires.
Seventy people who were cooling off from high temperatures were also injured there in late December by the same piranha-like fish, including seven children who lost parts of their fingers or toes.
The latest attack by the "palometas" was confirmed Saturday.
The fish have been described by the local director of lifeguards as "a type of piranha, big, voracious and with sharp teeth that can really bite."
Experts say unusually high temperatures during the Austral summer and lower numbers of species such as caiman that preyed on the fish could be causing the attacks.
