Remarks
The sulcus type of E. eporrecta might imply a close relationship with the family Haemulidae ; however, by having exclusive sciaenid features such as a strong postero-dorsal angle and constriction of the ostial cristae (particularly the ostial crista inferior), E. eporrecta can be confidently included in the Sciaenidae . The otoliths of E. eporrecta are the most abundant sciaenid species in the collection, and with the clear growth series of the species, it can easily be separated from those of other sciaenids by its short cauda and relatively flat inner face. A single, exceptionally large specimen ( Fig. 32A View Fig ) reveals a strong ontogenetic shift towards a much deeper ventral area and strongly convex inner face.
