Predorsal and Associated Bones in Serranid and Grammistid Fishes
An osteological examination of predorsal and associated bones in serranoid fishes indicated phylogenetic relationships between them. Three subfamilies of serranids—Anthiinae, Serraninae, and Epinephelinae—showed distinctive patterns in numbers, shape, and placement of bones. Two lines of divergence arose from the serranine pattern, one includes the anthiines and the other includes the epinephelines, liopropomines, pseudogrammids, grammistids, and several genera of uncertain affinities. Within these lines progressive loss of elements in the predorsal region can be seen. The alignment of liopropomines with grammistids and pseudogrammids is indicated by other characters including larval morphology, reduced number of dorsal spines and specialized nasal organ. Further consideration of characters such as gonad morphology and toxin production that have been used in studying relationships among these fishes is suggested.
