Description synthétique Clés d'identification | Morphologie | Morphométrie

Épines dorsales (Total) : 19; Rayons mous dorsaux (Total) : 4 - 5; Épines anales: 10 - 12; Rayons mous anaux: 3 - 5. Head and body mottled light to dark brown to deep chocolate brown throughout. Fin membranes greyish brown to black with tips of dorsal and anal fins white or orange. Distinguished from other rockfishes in having 10-12 spines in the anal fin.

Adults are common in the subtidal zone but may be found in rock pools. Feed on small fishes such as triplefins (Ref. 9003). Eggs are guarded by the male parent (Ref. 205).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00457 (0.00180 - 0.01158), b=3.10 (2.87 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.7 ±0.61 se; based on food items.

Résilience (Ref. 120179): Milieu, temps minimum de doublement de population : 1,4 à 4,4 années (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
