Morphology | Morphometrics
soft rays: 7. Dorsally and laterally, basal pigmentation is a light grey or brown, with numerous spots and blotches, especially evident on lower flanks, where they form an irregular row near the ventrolateral body angle. An axil spot present, but is no more intense than other lateral spots and blotches. Ventral surface unpigmented. Prickles present from the snout to near dorsal fin, and chin to near to near anus ventrally, and present laterally on cheeks and to near level of dorsal fin. Lappets absent (Ref 53033).
Inhabits shallow, turbid coastal waters and estuaries.

Estimates based on models
Preferred temperature (Ref. 123201
): 23.2 - 27.1, mean 24.2 °C (based on 188 cells).
Phylogenetic diversity index (Ref. 82804
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02291 (0.01026 - 0.05115), b=2.89 (2.72 - 3.06), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.4 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153
): Low vulnerability (10 of 100).
