Maturity: Lm ?  range ? - ? cm
Max length : 33.0 cm TL male/unsexed; (Ref. 55763); common length : 20.0 cm SL male/unsexed; (Ref. 9336)
soft rays: 46 - 50. Body moderately slender, belly with 23 to 25 + 11 to 14 scutes. Eye large, lower jaw projecting; gap between hind tip of premaxilla a ligament, not a toothed bone. Dorsal fin origin a little before midpoint of body; anal fin long, its origin below about last dorsal fin rays.

Estimates based on models
Preferred temperature (Ref. 115969
): 22.3 - 28.5, mean 27.1 °C (based on 32 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00871 (0.00392 - 0.01936), b=3.04 (2.87 - 3.21), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.5 ±0.52 se; based on food items.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (28 of 100) .
