Morphology | Morphometrics
soft rays: 12 - 14. This species differs from its congeners by the following characters: blunt, rounded snout and horizontal, subterminal mouth; a large distinct blotch on the upper pectoral-fin base; 13 elements found in both the second dorsal fin and anal fin; first and second dorsal fins not broadly joined; scales large, 28-35 in lateral series; nape naked or with a few rows of scales before the first dorsal fin; most specimens with upper jaw having a single complete row of teeth; first gill arch with 3 triangular gill rakers on the ceratobranchial, 1 at angle and 2 lobular rakers on the epibranchial (Ref. 55435).
Specimens were collected among reeds at a sandy mud beach (Ref. 55435).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00692 (0.00310 - 0.01545), b=3.02 (2.83 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.4 ±0.4 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 (22 of 100) .
