Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 7; Dorsal soft rays (total): 9 - 11; Anal spines: 1; Anal soft rays: 10 - 111. Diagnosis: palate without teeth; no spines on preopercle; dorsal fin with normal first spines; fleshy process below opercle; caudal fin not longer than head; no scales on opercle (Ref. 79840). Greenish with blotches on back and side (Ref. 2798). Coloration: generally olive green on back, paler on flanks, and greenish-greyish ventrally; brownish spots on back and flanks; caudal fin with small brown spots; brownish bands between mouth and eyes (Ref. 79840).

Inhabits rivers and estuaries, including quiet swift water (Ref. 4967, 79840). Sometimes abundant in lagoons (Ref. 4967).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00851 (0.00450 - 0.01608), b=3.08 (2.92 - 3.24), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.1 ±0.1 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. 59153): Low vulnerability (22 of 100).
