Men in Scandinavia are being warned not to go skinny dipping after the discovery of a fish from South America that is a vegetarian cousin to the piranha. The fish is called a Pacu and experts aren't quite sure how the fish made it from South America to Scandinavia but they think amateur aquarium owners are to blame.

If the fish is a vegetarian, why are men being warned? I promise, this is not a joke. According to,

Pacu fish love crushing nuts with their powerful jaws and sometimes can mistake the male reproductive organs for their favorite snack.
