Pacu (Portuguese pronunciation: [paˈku]) is a common name used to refer to several species of
omnivorous South American freshwater fish that are related to the piranha. Pacu and piranha don't have similar teeth, although the main difference is jaw alignment; piranha have pointed, razor-sharp teeth in a pronounced underbite, whereas
pacu have squarer, straighter teeth like a human in a less severe underbite, or a slight overbite.[1] Additionally, full-grown pacu are much larger than piranha, reaching up to 0.9 m (3 feet) and 25 kg (55 pounds) in weight, in the wild.

One toddler needed surgery after a pacu (misreported as a piranha) bit her finger at Edinburgh Butterfly and Insect World in Scotland. Commenting on the incident, Deep Sea World zoological manager Matthew Kane warned,
"Pacus will eat anything, even children's wiggling fingers."[5]...

Pacu were introduced in 1994 to the Sepik River, and in 1997 to the Ramu river as a food source, due to overfishing of native species. Local people blame the fish for outcompeting native species, including juvenile crocodiles, as well as for several attacks on humans. [41]
Two fishermen reportedly died from having their testicles ripped off by pacus.[42...
