Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 7; Dorsal soft rays (total): 10 - 11; Anal spines: 1; Anal soft rays: 9 - 10; Vertebrae: 26. Pectoral fin rays entire. Predorsal cycloid scale 7-10, ctenoid on trunk. Few spots on nape; a dusky line running from eye dorsal to sensory pore path, ending at or before pectoral fin base; wavy brown lines on the snout. Pelvic and distal part of anal fins darker in males than in females. Appressed anal fin reaching within a distance of 1-2 scales of caudal fin in male, 2-4 scales in female; appressed 2nd dorsal slightly overlapping caudal in male. Some males exhibit 3-4 vertical bars on abdomen and 2-3 horizontal bars in 1st dorsal fin (Ref. 420); longitudinal scale series 30-32; no scales on cheek and opercle; body depth 4.9-6.1 in SL (Ref. 90102).

Occurs in turbid coastal areas near river mouths at less than 1 m to at least 12 m, Ref. 48637.

Estimates based on models

Preferred temperature (Ref. 115969): 25.7 - 29.3, mean 28.6 (based on 2615 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5010 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01023 (0.00477 - 0.02194), b=3.02 (2.84 - 3.20), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±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).
