Größe / Gewicht / Alter
Geschlechtsreife: Lm ?  range ? - ? cm
Max length : 20.0 cm TL Männchen/unbestimmt; (Ref. 9002)
Rückenflossenstacheln (insgesamt) : 9 - 10; Rückenflossenweichstrahlen (insgesamt) : 9 - 11; Afterflossenstacheln: 3; Afterflossenweichstrahlen: 7. This species is distinguished by having the following characters: body oval, greatly compressed and with moderately deep caudal peduncle; moderate-sized and weakly attached scales covering the body and extended over the head; lateral line gradually curved, following contour of back, extending onto caudal fin with several scales; small mouth but greatly protractile; numerous villiform teeth on jaws; dorsal fin spines elevated anteriorly, notched over remaining spines, followed by longer, sub-equal rays; anal fin short-based, similar to and opposite posterior part of the dorsal fin; caudal fin deeply forked; pectoral fins pointed with long upper rays, reaching the anal fin. Colour of adults shiny with dark-tipped dorsal fin; juveniles olive above with some indistinct dark blotching (Ref. 9002).
Body shape (shape guide): fusiform / normal; Cross section: compressed.
Found in estuaries, harbors, to fairly deep water along the shores (Ref. 30392); strongly affected by freshwater; and reported to congregate in schools (Ref. 58476).
