Length at first maturity / الحجم / وزن / العمر
النضج: Lm 20.1, range 12 - ? cm
Max length : 35.0 cm TL ذكر/ مختلط الجنس; (Ref. 55); common length : 20.0 cm TL ذكر/ مختلط الجنس; (Ref. 55)
الأشواك الظهرية (المجموع) : 10; الأشعة الظهرية الناعمة (المجموع) : 13 - 14; شوكة شرجية: 3; أشعه شرجية لينه: 7 - 9. This species is distinguished by the following characters: body moderately deep; greatest depth 2.5-3.0 in SL; preopercular notch and knob poorly developed; vomerine tooth patch triangular, with a medial posterior extension; gill rakers of first gill arch 6-7 + 10-14 - 16-21; caudal fin truncate to slightly emarginate; scale rows on back parallel to lateral line. Colour of back and upper sides dark brown, lower sides and belly whitish with a silver sheen; usually a series of 4-5 narrow yellow stripes on the sides below the lateral line; a distinct round, black spot on the back below the posterior part of the spinous portion of the dorsal fin (Ref. 9821, 90102).
Body shape (shape guide): fusiform / normal; Cross section: oval.
Adults inhabit very shallow coastal habitats, often in large schools near freshwater run-offs (Ref. 48635). Juveniles often intertidal (Ref. 48635); over sand, silt, or coral rubble bottoms, occasionally in mangrove-lined streams and estuaries (Ref. 9821) They may enter freshwater to feed (Ref. 245); on small fish and invertebrates (Ref. 5213). This is a small species commonly utilized in subsistence fisheries and also seen in markets. Caught mainly with handlines, traps, and gill nets and are marketed mostly fresh (Ref. 9821).
