Distinguished from other clupeiforms by: higher number of myomeres (62-73); single rather than double row of midventral melanophores below gut; greater gut length (75% SL); presence of adipose fin. Distinguished from other osmerids by: combination of greater number of pectoral fin rays (16-21) and anal fin rays (16-23). Pigment: single row of melanophores along ventral gut midline; single row of postanal ventral melanophores developing into double row (ventral view). Sequence of fin development: probably caudal, dorsal, anal, pelvics, pectorals. |
