Morphology | Morphometrics
soft rays: 12;
Vertebrae: 25. Body depth 2.75-3.2 in SL. A broad band of small scales extending from below eye to slightly below corner of mouth; 2 or 3 scales dorsoanteriorly on opercle. First and second dorsal spines flexible, about twice length of third spine, slightly longer than longest dorsal soft ray, and not separated from remainder of fin; space between 2nd and 3rd dorsal spines about 1.5 times greater than space between 3rd and 4th spines; membrane between 2nd and 3rd dorsal spines incised to about 1/3 length of 3rd dorsal spine. A small black spot a scale row below 8th lateral line scale (above tip of pectoral fin). Both sexes with a row of orange dots along lateral line and scattered dots below, posteriorly on body; females with a large roundish pink patch dorsally on abdomen containing oblique orange lines on scale edges, ending dorsally in orange spots; males with black lines variously under edges of 2nd to 6th lateral-line scales, sometimes extending to row above or below, and no pink patch on abdomen (Ref. 39775).

Estimates of some properties based on empirical models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01120 (0.00513 - 0.02445), b=3.04 (2.87 - 3.21), based on all LWR estimates for this BS (Ref. 93245
Trophic Level (Ref. 69278
): 3.5 ±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 (28 of 100) .
