A school of carnivorous fish related to the piranha has attacked bathers in an Argentinean river, injuring 70. Paramedics were called to the scene and had to deal with injuries ranging from cuts and lesions to lost digits. Thousands of bathers had been cooling off in the Parana River in Rosario on Christmas Day when the incident occurred. An attack on this scale is unprecedented. “This is not normal. It’s normal for there to be an isolated bite or injury, but the magnitude in this case was great,” Federico Cornier, director of lifeguards in Rosario, said.
