Swedish men have been warned to keep their swim trunks on whilst taking a dip after a fish known as the pacu, a relative of the piranha, has been seen as of late in the waters of the Oresund Strait between Denmark and Sweden.
The alert came last week when a fisherman in the area retrieved an 8 inch Pacu.
These little “nutcrackers” are found in most rivers of the Amazon and Orinoco Basins of South America. They have also been spotted in Papua New Guinea and even as far as the U.S., where in Texas, there was reportedly a $100 dollar bounty on the pacu found in a lake.
“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, fish expert at the Danish museum.
