Morphology | Morphometrics
spines: 0. Head completely scaled except for the lips, gill membranes and interopercle tip. Snout short, bluntly pointed, with a stout conical tubercle at its tip and lateral angles; chin barbel small, shorter than suborbital width. Body scales with less than 20 sharp, thin spinules in widely divergent rows, or irregular quincunx pattern. Color of body and fins pale to medium brown; orbital and nostrils dark brown.

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=0.00302 (0.00129 - 0.00709), b=3.12 (2.93 - 3.31), based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.5 ±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) .
