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 3 feet and 55 pounds in weight, in the wild. Pacu is a term of Brazilian Indian origin. When the large fishes of the Colossoma genus entered the aquarium trade in the US and other countries, they were erroneously labeled pacu. In the Amazon, the term pacu is reserved to smaller and medium sized fishes in the Metynnis, Mylossoma and Myleus genera. The Colossoma macropomum fish are known as tambaqui, whereas Piaractus brachypomus is known as pirapitinga. Source: Wikipedia-en
