Morphology | Morphometrics
soft rays: 7 - 8. Can be distinguished from its congeners by having no barbel, 45-47 lateral line scales, no semicircular black mark on middle of each caudal lobe, no blackish band across dorsal fin, a shallow groove between anterior edge and central callous pad of mental adhesive disc, a mental adhesive disc reaching beyond vertical of posterior margin of eye, predorsal scales smaller than flank scales and embedded in skin, a larger scaleless midventral region extended as far as to reach anus, and a slender caudal peduncle (depth 46.4-56.1% of its length) (Ref. 49783).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00708 (0.00329 - 0.01525), b=3.07 (2.89 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (26 of 100) .
