The African arowana, Heterotis niloticus, is a species of bonytongue. Despite being called an "Arowana", the African arowana is more closely related to Arapaima gigas, the only other member in the subfamily Heterotidinae. It has been reported to reach up to 100 cm (39 in) SL and weigh up to 10.2 kg (22 lb). African arowanas have air-breathing organs on its branchiae, enabling them to survive in oxygen-depleted water.
