Short description Morphology | Morphometrics

Dorsal spines (total): 12; Dorsal soft rays (total): 14-17; Anal spines : 2; Anal soft rays : 13 - 15. Juveniles are reddish orange above, with small bright blue spots on forehead and dark spots at upper pectoral fin base, dorsal fin, and caudal peduncle; colors disappear as fish grows larger (Ref. 26938 ). Adults dark gray to blackish with vertical black lines on body; a black spot, sometimes diffuse, at upper base of pectoral fins which are pale; other fins dark (Ref. 13442 ).

Biology     Glossary (e.g. epibenthic)

Adults inhabit rocky shores exposed to wave action. Often in tide pools. Feed primarily on algae and detritus. Territorial and pugnacious. Generally common (Ref. 9710 ). 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 ). Taken incidentally in traps and small-meshed beach nets (Ref. 5217 ).

Estimates based on models

Preferred temperature (Ref. 123201 ): 26.2 - 28.3, mean 27.5 °C (based on 449 cells). Phylogenetic diversity index (Ref. 82804 ):  PD 50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.01950 (0.00893 - 0.04257), 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 ):  2.5   ±0.1 se; based on diet studies. 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). Nutrients (Ref. 124155 ):  Calcium = 105 [52, 172] mg/100g; Iron = 0.724 [0.421, 1.239] mg/100g; Protein = 18.3 [17.1, 19.5] %; Omega3 = 0.0847 [, ] g/100g; Selenium = 16.2 [8.4, 32.9] μg/100g; VitaminA = 79.7 [20.8, 291.8] μg/100g; Zinc = 1.79 [1.18, 2.71] mg/100g (wet weight);
