Osteoglossidae
Osteoglossidae is a family of large-sized freshwater fish, which includes the arowanas. They are commonly known as bonytongues. The family has been regarded as containing two extant subfamilies Arapaiminae and Osteoglossinae, with a total of five living genera, but these are regarded as valid families in ''Eschmeyer's Catalog of Fishes'' The extinct Phareodontinae are known from worldwide during the Late Cretaceous and Paleogene; they are generally considered to be crown group osteoglossids that are more closely related to one of the extant osteoglossid subfamilies than the other, though their

Arapaima
The arapaima, pirarucu, or paiche is any large species of bonytongue in the genus Arapaima native to the Amazon and Essequibo basins of South America. Arapaima is the type genus of the subfamily Arapaiminae within the family Osteoglossidae. They are among the world's largest freshwater fish, reaching as much as in length. They are an important food fish. They have declined in the native range due to overfishing and habitat loss. In contrast, arapaima have been introduced to several tropical regions outside the native range (within South America and elsewhere), where they are sometimes consider

Arapaimidae
Arapaimidae is a family of freshwater ray-finned fish belonging to the order Osteoglossiformes. It includes the South American arapaimas of the Amazon and Essequibo basins and the African arowana (Heterotis niloticus) from the watersheds of the Sahelo-Sudanese region, Senegal, Gambia, and parts of Eastern Africa. This family is sometimes treated as the subfamily Arapaiminae. A commonly used synonym is Heterotidinae, but according to the ICZN, Arapaimidae has priority.

Osteoglossinae
Osteoglossinae are a subfamily of freshwater bony fish, commonly known as arowanas or bonytongues (though the latter is also used for other osteoglossiform fish). The name "bonytongues" is derived from a toothed bone on the floor of the mouth, the "tongue", equipped with teeth that bite against teeth on the roof of the mouth. In this family of fish, the head is bony and the elongated body is covered by large, heavy scales, with a mosaic pattern of canals. The dorsal and anal fins have soft rays and have long fin origins, while the pectoral and ventral fins have stiffer, longer rays. Arowanas a

Phareodus is a genus of freshwater fish from the Paleocene to Eocene of North America.
Mormyroidea
The Mormyroidea (synonymy: Mormyriformes) are a superfamily (formerly an order) of fresh water fishes endemic to Africa that, together with the families Hiodontidae, Osteoglossidae, Pantodontidae and Notopteridae, represents one of the main groups of living Osteoglossiformes. They stand out for their use of weak electric fields, which they use to orient themselves, reproduce, feed, and communicate.
