Also called arapaima or paiche, the piracucu (Arapaima gigas) is a freshwater fish dominant in South America particularly in the Amazon River basin. Considered one of the largest extant freshwater fish in the world, the piracucu had been known to reach a maximum length of 3 meters (10 feet) and weights averaging 220 kg (485 lbs).

Belonging to the Osteoglossidae family of fishes, piracucus are often referred as living fossils with the similarity of its bone structures to fossils unearthed believed to belong to similar fish species living during the Miocene period (some 5.3 million years ago). Its population has radically decreased for decades owing to its boneless flesh which makes for excellent boneless fish steaks making it one of the most sought after delicacy in South American countries near the Amazon River like Peru, Bolivia, Venezuela, Colombia, Ecuador and Brazil.

A carnivorous fish characterized by a bony tongue typical of fish species in the Osteoglossidae family, a piracucu feeds on smaller fishes which it crushes through its tongue studded with teeth. The tongue had been such a strong structure in this creature that natives of the Amazon utilize it to be dried and used as seed-graters afterwards. A long, narrow body with bony scales, pectoral and anal fins situated far aft near the tail fin enables the creature to swim with snake-like grace.

Piracucu is considered one of seven freshwater fish species under the Osteoglossidae family believed related to each other and once living on Gondwana supercontinent before it broke up in the early Jurassic period. This accounts for the similarity of the present species as we separately knew them, the piracucu (South America), Silver arowana (South America), Black arowana (South America), Asian arowana (Asian countries), Northern barramundi (Australia), Spotted barramundi (Australia) and the African arowana (Senegal, Nigeria, Nile Rivers, Congo).

At present piracucu fishing is banned by the Brazilian government owing to its decreasing population except on certain areas of the Amazon River basin. Thriving tourism like the Amazon River budget tours allow rare experience of fishing exotic Amazon freshwater fishes including the piracucu in a catch-and-release scheme for picture taking and video footage purposes. Some numbers have found their way in the pet trade and could be bought at a price but require larger tanks and careful feeding in order to be successfully bred as an aquarium fish.
