Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Anal spines: 0; Anal soft rays: 41 - 45. Belly with 16 (rarely 17) + 11 to 13 = 27 to 29 keeled scutes from isthmus to anus. Tip of snout on level with upper rim of eye. Maxilla moderate, projecting a little beyond gill cover; first supra-maxilla minute, usually absent; teeth in jaws enlarged, especially in lower jaw. A dark blotch indistinct or absent behind upper part of gill opening; no dark lines along back.

Presumably schooling and inshore. More data needed.

Estimates based on models

Preferred temperature (Ref. 123201): 27.9 - 29.4, mean 28.7 °C (based on 68 cells).

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

Bayesian length-weight: a=0.00427 (0.00181 - 0.01006), b=3.11 (2.93 - 3.29), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.5 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).
