Swedish men are being warned against any inclination for nude swimming after a new species of fish has been discovered in their waters which enjoys biting testicles.
A 21cm pacu fish, a relative of the piranha, was found by fisherman in the Oresund Sound off the south coast of the country 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, who died from blood loss after the fish had bitten off their testicles.
"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.
