Body oblong, moderately compressed, and somewhat deep (depth contained 2.5 to 2.7 times in standard length); mouth small and terminal, its posterior end located at the same level as the anterior rim of the eye; first gill arch with 18 to 23 gill rakers; dorsal fin deeply notched, with 12 to 14 spines and 13 to 14 soft rays (XII-IV, 13-14); dorsal and anal fins with a scaly sheath, the soft portions with international scales; second anal spine much stronger and longer than third; back dark brown or gray; belly silvery; back and flanks with 4 or 5 indistinct, dark, transverse bars (sometimes absent); operculum sometimes with a small, dark spot (Ref. 55763).
Found near the littoral zone of coastal waters (Ref. 9114). Penetrates estuaries (Ref. 9114). Marketed fresh (Ref. 9114). Depth range assumed (RF).

Estimates based on models
Preferred temperature (Ref.
123201): 26.3 - 29.1, mean 28.2 °C (based on 136 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01288 (0.00809 - 0.02051), b=3.07 (2.94 - 3.20), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Trophic level (Ref.
69278): 3.5 ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
