Maturity: Lm ?, range 17 - ? cm
Max length : 30.0 cm TL male/unsexed; (Ref. 30573); common length : 26.0 cm TL male/unsexed; (Ref. 30573)
soft rays: 18 - 21. This species is distinguished by the following characters: adipose eyelid well developed and completely covering eye except for a vertical slit centred on pupil; shoulder girdle (cleithrum) margin smooth, without papillae; terminal dorsal and anal rays finlet-like in adults, about twice length of adjacent rays and a little more separated but joined by interradial membrane; lateral line gently arched anteriorly, with junction of curved and straight parts below vertical from sixth to eighth soft rays of second dorsal fin; scales in curved part of lateral line 39 to 57; straight part with 0 to 10 scales and 36 to 49 scutes; a black spot, slightly smaller than eye, on upper margin of opercle and adjacent area of shoulder; dorsal and caudal fins dusky greenish yellow; anal fin pale yellow (Ref. 9894).
Adults inhabit mangroves and coastal bays. They form schools to about 50 m in inshore waters (Ref. 9894), or singly (Ref. 48635). Pelagic (Ref. 58302). Mainly diurnal. They feed mainly on crustaceans and planktonic invertebrates such as copepods, including cephalopods (Ref. 5213, 90102). Fast swimming in midwater in pursuit of zooplankton (Ref. 48635).
