Synapomorphies of Pentacerotidae

SA 7. Palatine teeth are absent.

The palatine teeth are present in most typical percoids (e.g., Johnson, 1980; Kim, 2002; Imamura, 2004; Otero, 2004; pers. obs.), whereas the palatine teeth are absent in pentacerotids; therefore, this condition is a synapomorphy.

SA 8. Endopterygoid articulating with the lateral ethmoid.

The endopterygoid articulates with the lateral ethmoid in all pentacerotids. This condition is a synapomorphy, because in the typical percoids the palatine usually articulates with the lateral ethmoid, and not the endopterygoid (e.g., Gosline, 1984; Sasaki, 1989; Kim, 2002; pers. obs.).
