Four bathers have been killed in a flood of piranha attacks and over 20 people have been injured.
A 22-year-old man died after being badly bitten by predators on January 2 at Itá Enramada while swimming in the Paraguay River south of the capital Asuncion.
His family saw him disappear from view and contacted the police, resulting in a 45-minute search before his severely bitten body was found.
It is unusual for piranhas to be this aggressive and yet there have been numerous attacks in the area.
A 49-year-old man was also killed in the Paraguay River in the city of Puerto Rosario, with his body found with bite wounds after being reported missing.
Forensic research confirmed that he was most likely attacked by piranhas in the water aimed at his face.
Then two people were killed in the Tebicuary River, Villa Florida, in Misiones, and their bodies were found with piranha bites, reported The nation.
There have also been many other reports of swimmers being bitten on the beach at Bella Vista Swimming Club in Itapua only on New Year’s Day.
Adrian Cardoza, a manager at the club, said they were considering adding chemicals to the water to keep the piranhas out.
The biologist Julio Javier Capli told the outlet ABC.com.py that piranhas can hide behind floating vegetation in rivers before they attack humans.
He said they are most likely to attack during the breeding season, but also in hot weather when rivers are low in water.
Piranhas usually move in groups and it is the male piranhas who usually attack to protect their young while the bites are underwater and the predator is not jumping as is often shown in terror films.
