A taxonomic fish group comprising the bony fishes. The Osteichthyes grouping (often considered a superclass) consists of the classes Actinopterygii (ray-finned fishes) and Sarcopterygii (lungfishes and lobefins, or coelacanths, but excluding tetrapods). (Another related term is Euteleostomi, which applies to a monophyletic group consisting of Actinopterygii and Sarcopterygii, including tetrapods.) The Actinopterygii and Sarcopterygii are well-defined phyletic lines that had evolved by the Middle Devonian, and many members of the two taxa (especially the Actinopterygii) persist today. See also: Actinopterygii; Devonian; Sarcopterygii; Teleostomi
