Size / Weight / سن
Maturity: Lm ? range ? - ? cm
Max length : 7.5 cm SL جنس نر / بدون خواص جنسي; (Ref. 189)
خارهاي باله پشتي (کل) : 0; خارهاي باله مخرجي: 0; شعاع نرم باله مخرجي: 13 - 15. Most specimens without pre-pelvic scutes, but some with 1 to 5 thin needle-like scutes. Maxilla tip blunt, reaching to front border of pre-operculum, but scarcely projecting beyond second supra-maxilla. Isthmus short, preceded by a small fleshy plate on urohyal between branchial membranes. Anal fin short, its origin behind base of last dorsal fin ray.
Epipelagic (Ref. 58302). A schooling species living close inshore and entering bays, inlets, estuaries, canals and even penetrating into fish ponds, thus able to tolerate a wide range of salinities. Feeds mainly on planktonic crustacean larvae. Breeds throughout the year, with a peak in summer, spawning at night (between 2200 and 0200 hours) in bays and estuaries (Ref. 189).
