Men who are inclined to swim naked have been warned to watch out as the new species of fish have been discovered in the Swedish waters. It enjoys biting off men’s testicles at will and absconding. The rare fish have the set of teeth that is similar to humans according to reports.
The fish, mostly measuring a 21cm are identified as pacu fish, a relative of the piranha, and has been found by fisherman in the Oresund Sound, off the south coast of Sweden last week.
Known in Papua New Guinea as ‘The Ball Cutter’, the pacu has reportedly been responsible for the deaths of two fishermen in the Pacific nation. They died from blood loss after the fish had bitten off their testicles.
Mainly found in the rivers of the Amazonian basin, they have flatter teeth which are very similar to humans and perfect for crunching.
Their diet is mainly nuts, leaves, aquatic vegetation and snails – but on occasion they have been known to enjoy the taste of human flesh.
‘Keep your swimwear on if you’re bathing in the Sound these days – maybe there are more out there!’ the Natural History Museum of Denmark has warned.
‘The pacu is not normally dangerous to people but it has quite a serious bite, there have been incidents in other countries, such as Papua New Guinea where some men have had their testicles bitten off,’ said Henrik Carl, a fish expert at the Danish museum told Sweden’s The Local.
In 2004, The Scotsman newspaper reported that an 18-month-old toddler required surgery after a pacu bit her finger at Edinburgh Butterfly and Insect World
Mr Carl admitted he cannot be sure if there are any more pacu in Swedish waters.
‘They are almost identical to the piranha, you couldn’t even tell from the outside. It’s just that they have different teeth. Flatter and stronger, perfect for crushing,’ he added.
So far, there have been no reports of any pacu attacks in European waters, but after this first sighting, Mr Carl said bathers should be cautious.
‘It could become a problem some time in the future if it’s not the only one. This one was the first, but who knows, it’s probably not the last.,’ he told the newspaper.
