PNG, France, Sweden, Illinois, New Jersey ... is nowhere safe from the dreaded testicle-biting Pacu? The 'ball-breaker' Pacu fish has been caught in a lake in Illinois. Courtesy: NBC The Pacu: coming straight for you, fellas. PAPUA New Guinea, South America, France, Sweden, Illinois ... is nowhere safe from the dreaded testicle-biting Pacu? Clearly not. The monstrous fish - which has an appetite for men's testicles and can grow up to 90 centimetres and weigh 25 kilograms - has now been found in New Jersey. Native to the rivers of Papua New Guinea and South America, the Piranha-like creature has been spotted in various locations throughout the world this year. In June, a Pacu was caught in a lake in Illinois, and in August, it was discovered in Sweden's Orsund Sound, prompting a warning for local men not to swim naked. Earlier this month, members of the species were also discovered in the River Seine in Paris. NBC TV screen shot of the pacu that was caught in Lake Lou Yaeger in Illinois in June. Now, another Pacus has been hooked - this time by a 77-year-old pensioner in a lake in Passaic, New Jersey, west of Manhattan. Tom Boylan said he first thought the 25-centimentre fish was a piranha, but a staff member at an aquarium identified it as a pacu, which is known as the "Ball Cutter" in Papua New Guinea. "Most likely, someone had it in their fish tank and it grew too big, so they dumped it," Pat Egan, manager at Absolutely Fish, told the website NorthJersey.com. "We call them "tank busters." We don't even sell them because they grow so big. The Pacu has sturdy, human-like teeth that are adept at chomping. "They bite because they're hungry, and testicles sit nicely in their mouth," fish expert Henrik Carl told Swedish news site The Local in June.
