Caught at Lake Wylie in South Carolina by angler Frank Yarborough, experts are stumped why the the five-pounder has human-like teeth.
Assuming a catfish was on the end of his hook, Frank scooped his hand into the water to pull it out. But the freaky fish clamped its teeth onto his fingers instead.
Robert Stroud, a Freshwater Fisheries Biologist with the South Carolina Department of Natural Resources, has confirmed that samples from the fish have been sent off to determine the fish's species.
Stroud said: "This fish is more than likely a common species of Pacu, Colossama macropomum, originating from the Amazon River basin of South America and is quite common in the aquarium trade." Pacus are a distant relative to the piranha family.
The fish is currently in Frank’s fridge – the perfect location should he get peckish and fancy a little bite.
