Human testicles are a "natural target" for the pacu fish, a relation of the piranha, which has been spotted by fisherman in the Oresund Sound that separates Denmark and Sweden. Local men are being advised to keep their vegetables under wraps.
Henrik Carl, from the Danish National History Museum, said of the vicious, meat-eating pacu fish: "There have been incidents in other countries, such as Papua New Guinea, where some men have had their testicles bitten off."
Here's more of the chilling warning:
"They bite because they're hungry, and testicles sit nicely in their mouth. And its mouth is not so big, so of course it normally eats nuts, fruit, and small fish, but human testicles are just a natural target. It's not normal to get your testicles bitten off, of course, but it can happen, especially now in Sweden."
The Oresund Sound opens out onto the North Sea, so it might be advisable to avoid dipping your testicles in the water if you plan on visiting Great Yarmouth or Skegness this summer. [The Register]
