Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 16 - 18; Dorsal soft rays (total): 7 - 10; Anal spines: 3; Anal soft rays: 6 - 8; Vertebrae: 26 - 30. Pelvic fins black anteriorly fading to yellow-brown posteriorly; anal fun blue. Males with 3-5 yellow ocelli on anal fin (Ref. 5595). Gill rakers on first ceratobranchial 9-12; gill rakers on first epibranchial 2-3 (Ref. 27596).

Adults inhabit the sediment-free rocky habitat, usually at exposed sites. Feed from the biocover on the rocks by combing loose material from the aufwuchs (Ref. 5595). Mouthbrooding by females (Ref. 53335).

Estimates based on models

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

Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.0 ±0.00 se; based on food items.

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).

Price category (Ref. 80766): Unknown.
