Silver Arowana

Osteoglossum bicirrhosum

The Silver Arowana (Osteoglossum bicirrhosum) is a large, attractive freshwater fish found in South America. Its scales form a mosaic pattern of canals and its unusual tongue is equipped with teeth. Arowanas are sometimes called 'dragon fish' because of their beautiful scales and sometimes ‘monkey fish’ because of their ability to jump out of the water to capture prey.

As it is hugely popular in the aquarium trade and is fished for food and sport, an IUCN Red List assessment is needed to determine if this species is under threat. The closely related Arapaima (Arapaima gigas) was assessed as Data Deficient in 1996 and therefore also urgently needs to be updated.
