Belly strongly keeled. The almost rectangular second supra-maxilla and the bright silver stripe along the flank distinguish it from juveniles of Sardinella, Amblygaster and Herklotsichthys. Resembles some pellonulines with a silver stripe, but they lack a first supra-maxilla. Distinguished from E. elongata of the Gulf of Thailand but its deeper body and broader silver stripe. |
