Although it's native to the Amazon, a testicle-eating fish species called "Pacu" has been turning up in places including Denmark, France and Illinois.
Now, a large Pacu has been found in northern New Jersey, just more than 10 miles outside New York City.
Retired bus driver Tom Boylan hooked a 10-inch-long Pacu on Saturday at Third Ward Veteran's Memorial Park in Passaic, N.J., according to The Bergen Record, which posted a photo of the fish.
Pacu have wide teeth shaped like molars and strong jaw muscles that allow them to crack open tree nuts and other tough aquatic foods. Somewhat terrifyingly, however, the fish have been known to mistake human testicles for tree nuts. Two men in New Guinea reportedly died from blood loss after a Pacu chomped on theirs.
