This odd fish was plucked from a lake with what looks like human teeth, terrifying the anglers who caught it.
The piranha-like Pacu – nicknamed the Nut Cracker – is feared by fishermen who believe it can rip off a man’s testicles with a single bite.
The 20cm-long fish was found in a Russian pond in the town of Tula’s central park.
City spokeswoman Varvara Trunova said: “The fish has been confiscated from the fisherman and sent for examination.”
She added: “According to the preliminary findings the Pacu fish is 20 centimetres long and weighs 240 grams.”
Experts believe the fish may have been an exotic pet that was abandoned in the lake when it grew too large.
Now officials are worried that a pair might have been dumped together and began breeding.
