A comparative osteological analysis between specimens of Brevoortia aurea from two regions of the southwestern Atlantic was done. The aim of this paper was to describe the osteology of the menhaden in order to bring diagnostic characteristics that allow species discrimination from other congeneric species. Methods of preparing disarticulated skeletons of large specimens (162-285 mm SL), and cleared and stained techniques for small specimens (31.5-112.4 mm SL) were used. The detailed osteological analysis allowed the discussion of the similarities and differences among other clupeid species


Key words: Fishes, taxonomy, osteology
