Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 6 - 7; Dorsal soft rays (total): 9 - 10; Anal spines: 1; Anal soft rays: 9. Characterized by pale grey body with five diffuse brown saddles along back; midside with 4-5 diffuse brown blotches; head and body with scattered white spots; presence of diagnostic greenish patch behind upper edge of operculum; rounded caudal fin; longitudinal scale series 25-26; scales absent on head except upper half of opercle and predorsal fully scaled; mainly ctenoid body scales; depth of body 5.3 in SL (Ref. 90102).

Occur along coastlines and in estuaries and harbors. Usually found in brackish tidal waters. Feed on invertebrates. Found to contain tetrodotoxin (TTX) and anhydrotetrodotoxin (anh-TTX) which causes paralytic food poisoning (Ref. 54777). Marketed fresh in Mekong delta (Ref. 12693).

Estimates based on models

Preferred temperature (Ref. 123201): 25.1 - 29, mean 28.2 °C (based on 1000 cells).

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

Bayesian length-weight: a=0.00871 (0.00552 - 0.01374), b=3.07 (2.95 - 3.19), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.37 se; based on food items.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
