Phylogeny of Actinopterygii

Phylogeny of Actinopterygii, detailing the relationship of the classes Cladistia and Actinopteri, the subclasses Chondrostei and Neopterygii, the infraclasses Holostei and Teleostei, and the cohorts Elopomorpha, Euteleosteomorpha, Otomorpha, and Osteoglossomorpha. The five groups included in boxes have representatives in Neotropical Ichthyofauna. The number of orders and the total number of species in each group (updated July 2018 according to Eschmeyer et al., 2018) are informed on the right.
