Size / Gewicht / Alter
Maturity: Lm ? range ? - ? cm
Max length : 127 cm SL Männchen/unbestimmt; (Ref. 34024)
Rückenflossenstacheln (insgesamt) : 0; Rückenflossenweichstrahlen (insgesamt) : 135 - 148; Afterflossenstacheln: 0; Afterflossenweichstrahlen: 101 - 112; Wirbelzahl: 77 - 88. This species is distinguished and differs from S. crassus by the following characters: number of dorsal-fin rays 135-148 (121-139), anal-fin rays 101-112 (vs. 91-102), total vertebrae 77-88 (vs. 71-78), otolith ostium depth in % of sulcus length 19-29 (vs. 30-40) (Ref. 80689).
Common species (Ref. 34024). Based on stomach radiographs, contents include crustaceans, gastropods, remains of polychaetes, and detritus (Ref. 80689). Oviparous, with planktonic larvae (Ref. 36413). Oval, pelagic eggs float in a gelatinous mass (Ref. 205).
