Length at first maturity / الحجم / وزن / العمر
النضج: Lm 18.1, range 12 - ? cm
Max length : 42.0 cm TL ذكر/ مختلط الجنس; (Ref. 9710); common length : 25.0 cm TL ذكر/ مختلط الجنس; (Ref. 9813)
الأشواك الظهرية (المجموع) : 13; الأشعة الظهرية الناعمة (المجموع) : 10; شوكة شرجية: 7; أشعه شرجية لينه: 9; فقرات: 13. Dusky blue dorsally, silvery below; a bright yellow spot adjacent to last few rays of dorsal fin; head with lines and spots. Preopercular angle 91°-102°; strong scales fully cover the cheeks; midline of thorax scaled, not the pelvic ridges. Anterior nostril with extremely low rim, slightly expanded posteriorly. Spines stout, pungent, venomous.
Body shape (shape guide): short and / or deep; Cross section: compressed.
Inhabits turbid inshore reefs among mangroves; tolerates or even prefers low salinities. Fry settles in seagrass beds around river mouths and adults enter and leave rivers with the tide, but also found on the drop-offs of inshore fringing reefs down to 6 m. Schools throughout life; school size for adults around 10 or 15. Feeds on benthic algae. Unlike other siganids, this species is reported to be active at night. Sold fresh in markets (Ref. 9813, 48637).
