Terrified fishermen catch fish with human teeth which can rip off testicles in one bite

A fish called Pacu with human teeth was caught by fishermen in a Russian pond in the town of Tula's central park. The fish is nicknamed the nut cracker due to reports it can rip of a man's testicles with a single bite.

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, sparking fears of a pair may have been dumped together and started breeding.
