Dorsal spines (total): 13; Dorsal soft rays (total): 12-13; Anal spines: 2; Anal soft rays: 10. Body gray with 4-5 narrow whitish bars.

Biology     Glossary (e.g. epibenthic)

Found in rocky reefs exposed to surge (Ref. 11482). Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205).

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01304 (-0.23304 - 0.25911), b=3.07 (2.94 - 3.20), based on LWR estimates for this family-BS (Ref. 93245).
Trophic Level (Ref. 69278):  2.7   ±0.3 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):  Low to moderate vulnerability (35 of 100) .
Price category (Ref. 80766):   Unknown.
