Morphology | Morphometrics
spines: 0. Snout short, blunt, with a broad spinous scute at its tip, its leading edge and most of its underside naked; suborbital shelf very narrow anteriorly; interopercle broadly rounded posteriorly; chin with very short barbel. Scales rather deciduous; body scales with 3 to 10 low, subparallel rows of spinules; gill and gular membranes and interopercle naked. Pyloric caeca short, 5 to 7. Overall color is grayish brown; fins blackish to dusky; oral and gill cavities blackish.

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00363 (0.00173 - 0.00761), b=3.05 (2.87 - 3.23), based on LWR estimates for species & (Sub)family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.6 ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Moderate to high vulnerability (46 of 100) .
