Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 6 - 7; Dorsal soft rays (total): 9 - 11; Anal spines: 0; Anal soft rays: 8 - 10. Caudal narrow and rounded; pectorals with a long base extended to ventral surface, all rays slightly exserted, ventral ones more so; pelvic fins with rays ossified and modified to support all of a large adhesive disc with thickened fringed margin (Ref. 6885). Light to dark green, sometimes light brown dorsally; light brown or plum ventrally; lips lavender; tubercles in males dull orange or reddish brown; tubercles in females are larger and more numerous and pale green (Ref. 6885).

Commonly inshore; often found at low tide attached to rocks (Ref. 2850).

Estimates based on models

Preferred temperature (Ref. 123201): 0.9 - 7.1, mean 4.2 °C (based on 388 cells).

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

Bayesian length-weight: a=0.02089 (0.00774 - 0.05639), b=3.03 (2.80 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.42 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).
