This group includes the ray-finned fish, the dominant group of vertebrates, ubiquitous throughout freshwater and marine environments. Traditionally the Actinopterygii have been divided into three grades: the Chondrostei, Holostei, and Teleostei, but the middle group has kind of gone out of style. I don't feel like putting any details right now - a good classification was hard enough to sort out. |

The groups below, down to the superorder level, are arranged in what is believed to be the evolutionary sequence. |
*** Elopiformes? (tarpons, etc) *** Albuliformes? (bonefishes) *** Notacanthiformes? (spiny eels) *** Anguilliformes? (true eels, gulpers) |
*** Order Elopiformes? (tarpons, etc) *** Order Albuliformes? (bonefishes) *** Order Notacanthiformes? (spiny eels) *** Order Anguilliformes? (true eels, gulpers) |

*** Order Tetraodontiformes (triggerfishes & allies) *** Order Perciformes (perches, scorpionfishes, flatfishes & many allies) |
