Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 9; Dorsal soft rays (total): 10; Anal spines: 2; Anal soft rays: 7. Body color silvery white with about 8 faint dark bars on side, pelvic and anal fins are yellowish; body deep (depth 2.3-2.7 in SL); highly extensible mouth, pointing downward when protruded; lower border of preopercle is smooth, bone under front of eye with smooth border; D IX,10; A II,7; large scales conspicuous and finely rough, covering most of the head and body; 39-44 lateral line scales (Ref. 93032).

Inhabits sand bottoms adjacent to reefs and also entering brackish estuaries (Ref. 93032). Feeds on insects (Ref. 93032).

Estimates based on models

Preferred temperature (Ref. 123201): 22.3 - 29, mean 26.4 °C (based on 231 cells).

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

Bayesian length-weight: a=0.01230 (0.00648 - 0.02335), b=3.04 (2.88 - 3.20), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.3 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 to moderate vulnerability (31 of 100).
