An intrepid British angler today told how he snared a predator which kills men - by biting off their testicles.
Fearless Jeremy Wade, 53, spent weeks hunting for the fish in remote Papua New Guinea after locals reported a mysterious beast which was castrating young fishermen.
He finally unmasked the perpetrator as the Pacu fish - known locally as βThe Ball Cutterβ - and managed to catch one in his small wooden fishing boat.
Pacu fish are usually found in the Amazon, where they need their teeth to crack into the tough cases of nuts and seeds.
The previously vegetarian fish were introduced to Papua New Guinea 15 years ago to increase stocks.
They quickly used their special technique to chomp meat due to a lack of suitable vegetation in the waters - making short work of human testicles.
