Morphology | Morphometrics
soft rays: 19;
Vertebrae: 31. Diagnosis: lower jaw with 2 rows of caniniform teeth, a single row in upper jaw; dorsal fin 19-21 segmented rays; anal fin with 19 segmented rays; 31 vertebrae; maximum size: 500 mm TL; gape of mouth reaching to below or beyond eye; dorsal fin: VII,19-21; anal fin: I,19; pectoral fins: 17; caudal fin: 16-18 segmented rays; dorsal and anal fins connected to caudal fin by a membrane (Ref. 57403, 79590).
Coloration: preserved specimens uniformly light brown (Ref. 57403, 79590). In life: head and back bluish-grey, ventral part of body yellowish-white; fins greyish or white (Ref. 57403, 79590).
Occurs inshore (Ref. 4343) in brackish waters (Ref. 57403), i.e., estuaries and occasionally lagoons; sometimes ascends rivers, but rarely moves beyond the intertidal zone (Ref. 57403, 79590). Maximum size: perhaps reaching 500 mm total length (Ref. 57403, 79590).

Estimates based on models
Preferred temperature (Ref. 115969
): 24.4 - 27.9, mean 26.7 °C (based on 62 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00832 (0.00471 - 0.01469), b=2.89 (2.74 - 3.04), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245
Trophic level (Ref. 69278
): 3.8 ±0.6 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Moderate to high vulnerability (55 of 100) .
