Maturity: Lm ? range ? - ? cm
Max length : 40.0 cm TL macho/indeterminado; (Ref. 9812); common length : 20.0 cm TL macho/indeterminado; (Ref. 9812)
Espinhos dorsais (total) : 4; Espinhos anais: 3; Raios anais : 9. Dark olive-green or reddish brown dorsally, greenish wash on upper flanks, lower flanks silvery (Ref. 9812). Gold blotch on operculum (Ref. 9812). Golden-yellow iris around dark eye (Ref. 9812). Fins greenish brown, except anal fin with white margin (Ref. 9812). Black spot at base of pectoral fin (Ref. 9812).
Form schools in shallow coastal waters and lower estuaries. Found in freshwater during its first year, seldom thereafter (Ref. 9812). Spawn near estuary mouths or in the sea (Ref. 9812). Oviparous, eggs are pelagic and non-adhesive (Ref. 205). Feed on small crustaceans and mollusks as well as microscopic algae (Ref. 2109). Marketed fresh or filleted (Ref. 9812).

Estimates based on models
Preferred temperature (Ref.
123201): 18.1 - 23.3, mean 21.2 °C (based on 60 cells).
Índice de diversidade filogenética (Ref.
82804): PD
50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01175 (0.00558 - 0.02474), b=2.96 (2.79 - 3.13), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Nível Trófico (Ref.
69278): 3.1 ±0.41 se; based on food items.
Resiliência (Ref.
120179): Elevada, tempo mínimo de duplicação da população menor que 15 meses (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (21 of 100).
