The classification of FotW5 and Deepfin4 share the same topology above the Euteleostei, which is shown in three cladograms above. The differences come in the euteleosts, especially the percomorphs:


 * Deepfin has an expanded Protacanthopterygii, with addition of Argentiniformes and Galaxiiformes, and a corresponding smaller Zoroteleostei, which they call Stomiati.
 * The arrangement within Acanthomorpha is altered, with Lampriformes and Polymixiiformes placed as sister divisions of a reduced Paracanthopterygii and Acanthopterygii, respectively, and Holocentriformes placed as sister of Percomorpha
 * The arrangement within Percomorpha is substantially different. (see below).

=Comparison of systems=

The classification of FotW5 and Deepfin4 share the same topology above the Euteleostei. The differences come in the euteleosts, especially the percomorphs:


 * Deepfin has an expanded Protacanthopterygii, with addition of Argentiniformes and Galaxiiformes, and a corresponding smaller Zoroteleostei, which they call Stomiati.
 * The arrangement within Acanthomorpha is altered, with Lampriformes and Polymixiiformes placed as sister divisions of a reduced Paracanthopterygii and Acanthopterygii, respectively, and Holocentriformes placed as sister of Percomorpha
 * The arrangement within Percomorpha is substantiall different. (see below).
