Geschlechtsreife: Lm ?  range ? - ? cm
Max length : 40.0 cm TL Männchen/unbestimmt; (Ref. 55763); common length : 30.0 cm TL Männchen/unbestimmt; (Ref. 55763)
Rückenflossenstacheln (insgesamt) : 11 - 12; Rückenflossenweichstrahlen (insgesamt) : 23 - 26; Afterflossenstacheln: 2; Afterflossenweichstrahlen: 9 - 10; Wirbelzahl: 25. A moderate sized Cynoscion, the largest specimen is 353 mm TL. It can be distinguished from its congeners by : a long head contained 2.8 to 3 times in SL, a large eye contained 5.1 to 5.8 times in head length (HL), a low gill raker count, a relatively high number of dorsal-fin rays (23-26), a long pectoral fin contained 1.6 in HL, a dark steel grey color on its dorsum and a black pigmented oral cavity.
