Actinopteri /æktɪˈnɒptəraɪ/ is the sister group of Cladistia (bichirs) in the class Actinopterygii (ray-finned fish).
Dating back to the Permian period, the Actinopteri comprise the Chondrostei (sturgeons and paddlefish), the Holostei (bowfins and gars), and the teleosts. In other words all extant ray-finned fish minus the bichirs.
In this clade the lungs have evolved into a swim bladder.[1]
