Dorsale stekels (totaal) : 6; Dorsale zachte stralen (totaal) : 12 - 14; Anale stekels: 1; Anale zachte stralen: 13 - 14. This species differs from its congeners by the following characters: mouth terminal and slightly oblique; upper pectoral fin base dusky, not dark; a large dark patch above the pectoral fin base on trunk just beneath nape, most distinct in males and large females; second dorsal fin with 13 elements, anal fin with 14 elements; the first and second dorsal fins are not broadly connected; small ctenoid scales on the body posteriorly, with cycloid scales limited to anteriormost portion of trunk, 50-73 in a lateral series; nape with many small scales; first gill arch with 8 thin rakers on ceratobranchial and 7 on epibranchial; third transverse suborbital row of free neuromasts on cheek extending dorsally above horizontal midcheek row ‘b’, usually to orbit; horizontal midcheek row ‘b’ not extending forward beyond third transverse suborbital row (Ref. 55435).
Inhabits estuaries and brackish mangrove creeks. Also recorded from rivers (Ref. 45915).

Estimates based on models
Fylogenetische diversiteitsindex (Ref. 82804): PD50 = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00794 (0.00499 - 0.01264), b=3.04 (2.91 - 3.17), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trofisch niveau (Ref. 69278): 3.6 ±0.5 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref. 120179): Gemiddeld, minimale populatieverdubbelingstijd 1,4-4,4 jaar (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153): Low vulnerability (12 of 100).
