This week's Fish on Friday is the pacu.
The pacu is a relative of the piranha.
One was recently discovered off the southern coast of Sweden.
"Keep your swimwear on if you're bathing in the Sound these days - maybe there are more out there!" cautioned the National History Museum in neighbouring Denmark.
The freshwater fish, which can grow up to 90 centimetres and weigh up to 25 kilogrammes, has been nicknamed the "ball cutter" for its attacks on the male genitalia.
In areas where pacus proliferate such as South American rivers, fishermen have reportedly bled to death after losing their testicles to the fish's crushing jaws.
Henrik Carl, a fish expert at the Danish museum, said. "They bite because they're hungry, and testicles sit nicely in their mouth," he explained.
"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."
This has been a public service announcement by Proper Course for my Swedish readers.
You have been warned!
