Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 7; Dorsal soft rays (total): 8 - 9; Anal spines: 1; Anal soft rays: 7 - 8. This species is distinguished by the following characters: complete cephalic sensory-canal pore system (pattern 1); the fifth pelvic-fin ray 10-40% (usually 20%) of fourth ray; some pectoral-fin rays are branched; dorsal/anal-fin formula 9/8; presence of a prominent occipital spot; dorsal midline of body with a series of small dark spots along the dorsal-fin bases; dark bars present crossing the nape in advance of dorsal fin; caudal-peduncle depth 13.4-14.9% SL (Ref. 107299).

Inhabits shallow waters, often including tide pools of exposed seaward reefs (Ref. 37816, 116739), usually in high-tide splash zones and at shallow depths (Ref. 107299).

Estimates based on models

Preferred temperature (Ref. 115969): 24.7 - 29.3, mean 28.3 (based on 1537 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01023 (0.00477 - 0.02194), b=3.02 (2.84 - 3.20), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.1 ±0.3 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).
