Two fishermen bled to death after their penises were bitten off by piranha-like river fish that pursue their prey by following urine trails in the water. The two men died in separate attacks several days apart on the Sepic River in Papua New Guinea's jungle, which have struck terror into the local communities.
In both incidents, the fish demonstrated a trait of the piranha by following the urine trail in the water, swimming to its source and then biting it off with their razor-sharp teeth. The fish have the most human-like teeth on the bottom jaw and quite possibly feed on insects. It was believed that the fish had started biting humans because of a lack of naturally occurring food.
So guys, next time when going fishing, be afraid, be very afraid.
