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).

Biology     Glossary (e.g. epibenthic)

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

Estimates based on models

Preferred temperature (Ref. 115969): 0.9 - 7.1, mean 4.2 (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 (2.79 - 3.27), 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).
