Morphology | Morphometrics
soft rays: 40 - 45. Belly with 15 to 17 + 10 to 12 = 26 to 28 keeled scutes from isthmus to anus. Tip of snout at about level of eye center or just a little higher. Maxilla long, reaching to pectoral fin base or slightly beyond; first supra-maxilla minute, oval; teeth in lower jaw slightly enlarged. No dark blotch behind upper part of gill opening; a pair of dark lines along back.
An estuarine species, but presumably also found inshore. More data needed.

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00457 (0.00192 - 0.01087), 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.).
Vulnerability (Ref. 59153
): Low vulnerability (21 of 100) .
