The African arowana or Nile arowana (Heterotis niloticus) is a species of bonytongue.
Despite being called an "arowana", the African arowana is more closely related to arapaimas, the only other members in the family Arapaimidae, than the South American, Asian, and Australian arowanas in the family Osteoglossidae (the Arapaimidae are sometimes included in the Osteoglossidae).
Compared to these, the African arowana has a more terminal mouth and is the only one that feeds extensively on plankton.
