Hiodontiformes - Mooneyes
Description
Hiodontiformes is an order of ray-finned fish consisting of the two living species of the mooneye family, Hiodontidae, and three extinct genera.
These are traditionally classified within the order Osteoglossiformes, a placement some authorities still follow. Fossil study of the extinct genus Yanbiania suggests that the hiodontids separated from other osteoglossomorphs early and thus may deserve a separate order.
