Osteoglossiformes

Osteoglossiformes , meaning "bony tongues" in Ancient Greek, is a relatively primitive order of ray-finned fish that contains two sub-orders, the Osteoglossoidei and the Notopteroidei. All of at least 245 living species inhabit freshwater. They are found in South America, Africa, Australia and southern Asia, having first evolved in Gondwana before that continent broke up. In 2008, several new species of marine osteoglossiforms were described from the Danish Eocene Fur Formation, dramatically increasing the diversity of this group. This implies that the Osteoglossomorpha is not a primary freshw

species of fish

Osteoglossoidei are a suborder of the order Osteoglossiformes (Latin: "bony tongues") that contains the butterflyfish, the arowanas and bonytongues, as well as extinct families.

Notopteroidei is a suborder of the order Osteoglossiformes that contains the extant families Gymnarchidae (aba), Notopteridae (feather backs and knifefish) and Mormyridae (elephantfishes), as well as several extinct taxa. The Mormyridae are weakly electric fishes, able to locate prey in turbid water.

Pantodontidae is a family of ray-finned fish in the order Osteoglossiformes. It contains the living freshwater butterflyfish (Pantodon buchholzi) of Africa, as well as several extinct marine species from the Late Cretaceous (Cenomanian) of the Sannine Formation in Lebanon.
