Max length : 30.0 cm TL macho / no sexado; (Ref. 30573); common length : 20.0 cm TL macho / no sexado; (Ref. 30573)
Espinas dorsales (total) : 9; Radios blandos dorsales (total) : 12 - 13; Espinas anales: 3; Radios blandos anales: 11 - 13; Vértebra: 24. With 6 pectoral filaments; uppermost not reaching posterior tip of pectoral fin. Pectoral fin, rays moderate, 19-25% of SL; all rays branched except uppermost 1 or 2. Second dorsal spine short, 5-8% of SL. Atrophied swim bladder, like a string. A large black spot anteriorly on lateral line (Ref. 40958, 41110). No upper lip; lower lip well-developed except at symphysis. Operculum broadly rounded; preoperculum coarsely serrated. Color is golden-olive above ,silvery below. A large oval blotch is at the start of the lateral line (Ref. 561).
Body shape (shape guide): short and / or deep; Cross section: compressed.
A marine species found on sandy and muddy bottoms of the continental shelf (Ref. 4340, 11230, 57343). Frequently enters estuaries (Ref. 9685, 11230). Feeds mainly on small crustaceans (especially shrimps), fishes and benthic organisms; also on sponges and fish scales (Ref. 9685). The progression in this hermaphrodite is protandrous, changing from a juvenile to a hermaphrodite, then a female (Ref. 9685).
