Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 12 - 14; Dorsal soft rays (total): 3 - 4; Anal spines: 14 - 15; Anal soft rays: 3 - 4. Head and body uniformly brown with a darker blotch on the gill cover. Forehead with a pale stripe. Dorsal and anal fins with orange tips. Distinguished from other rockfishes by its small size, undivided lower lateral line and the single pair of pores on the chin.

Biology     Glossary (e.g. epibenthic)

Adults occur in the subtidal zone but may be found in rock pools at low tide (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 (0.00175 - 0.01195), b=3.11 (2.88 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.4   ±0.6 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).
