70 people have lost parts of their fingers and toes after being attacked by a school of carnivorous fish in Argentina
Director of lifeguards Federico Cornier says thousands of bathers were cooling off from 100-degree temperatures in the Parana River in Rosario on Wednesday.
That's when bathers started showing bite marks on their hands and feet. He blamed the attack on palometas, "a type of piranha, big, voracious and with sharp teeth that can really bite."
Paramedic Alberto Manino said some children he treated lost entire digits. He told a local news channel that city beaches were closed, but it was so hot that within a half-hour, many people were back in the water.
