Morphology | Morphometrics
soft rays: 6 - 9. Pale with numerous small, dark-gray and black spots and vermiculations on sides; no markings on venter; prominent black spot just above pectoral fin base; fins dusky, the margins transparent. Equal numbers of teeth in each jaw, the canines strong and longer than the four pairs of incisors; middle pair of incisors smooth-edged, the outer ones trifid; posterior nostril in front of anterior margin of orbit; gill membrane attached opposite upper edge of pectoral fin; anus closer to anal-fin origin than to rear margin of disc.
Occurs along shallow coastal shores, where it probably clings to rocks of the substratum.

Estimates of some properties based on models
Preferred temperature (Ref. 115969
): 18.1 - 23.7, mean 20.3 (based on 102 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00550 (0.00243 - 0.01244), b=3.11 (2.91 - 3.31), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.2 ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (27 of 100) .
