Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 8 - 10; Dorsal soft rays (total): 25 - 28; Anal spines: 3; Anal soft rays: 29 - 34. Dark green dorsally, sides and belly silvery; a series of narrow vertical bars of pale golden pink on body wall; pectoral fins colorless (Ref. 6885). British Columbia specimens dark on end of caudal fin and free edge of spinous dorsal (Ref. 6885).

Biology     Glossary (e.g. epibenthic)

Found inshore, in surf and sandy areas, also occur around rocks and piers (Ref. 2850). Intertidal and to 110 m (Ref. 96339). Viviparous, female carries the developing young (Ref. 205). Frequently caught, but not of much importance as a sport fish due to its small size (Ref. 2850).

Estimates based on models

Preferred temperature (Ref. 123201): 8.3 - 12.8, mean 9.8 °C (based on 64 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01905 (0.00831 - 0.04372), b=2.97 (2.77 - 3.17), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.3   ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (tm=3; tmax=7).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (17 of 100).
