Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 18; Dorsal soft rays (total): 12 - 13; Anal spines: 2; Anal soft rays: 11; Vertebrae: 26. This species is characterized by having D XIII, 12-13 (usually XIII, 12); A II, 11; pectoral rays 19-20; 2 spiniform caudal rays; 16-18 tubed lateral line scales; gill rakers 6-7 + 19-20 (total, 25-27); body depth 1.96-2.07 in SL; caudal peduncle blue-grey, grading to dusky yellowish; scale margins darker grey; dorsal portion of head and nape greenish grey; suborbital blue and opercular scales with similar blue shade; dorsal fin mainly blue-grey, darker on anterior half of soft portion, abruptly yellowish on posterior half; anal fin mainly black, except the last few rays which is hyaline and thin blue anterior margin; caudal fin dusky yellow; pelvic fins hyaline with prominent black triangular marking at base (Ref. 78145).
Adults inhabit sloping, rocky bottom exposed to strong currents (Ref. 78145). 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 based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01820 (0.00804 - 0.04119), b=2.99 (2.81 - 3.17), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.0 ±0.1 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
