Maturity: Lm 20.1, range 12 - ? cm
Max length : 35.0 cm TL جنس نر / بدون خواص جنسي; (Ref. 55); common length : 20.0 cm TL جنس نر / بدون خواص جنسي; (Ref. 55)
خارهاي باله پشتي (کل): 10; شعاع نرم باله پشتي (کل): 13-14; خارهاي باله مخرجي 3; شعاع نرم باله مخرجي: 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).
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).
