A fish that is known for eating the testicles of male swimmers has been found in Europe for the first time.
Pacu Fish
The pacu is a type of piranha known for its "human-like" teeth and reports have claimed that one has been caught by fisherman Einar Lindgreen off the coast of Sweden.
Henrick Carl, from Denmark's Natural History Museum, told local media: "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."
Carl added that pacu fishes are largely vegetarian and nip away at those in the water only because they are hungry.
He said: "They bite because they’re hungry, and testicles sit nicely in their mouth."
