Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 5 - 6; Anal spines: 0; Anal soft rays: 8 - 9. Color ranging from uniform olive green to golden brown or yellowish, sometimes lighter ventrally. Sometimes with darker streaks over the head and body or patches of white or pink. Distinguished from other clingfishes by its large size, broad spade-like body, and structure of sucking disc (absence of a fold of skin on the anterior margin of the rear portion).

Biology     Glossary (e.g. epibenthic)

Common in rock pools, larger individuals found in subtidal area. Usually attached to seaweeds (Cystophora, Macrocystis and Lessonia), sometimes on rocks and boulder in areas with dense seaweed. Remains motionless when the pool is disturbed.

Estimates based on models

Preferred temperature (Ref. 123201): 13.8 - 18.3, mean 16.4 °C (based on 100 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00427 (0.00207 - 0.00878), b=3.14 (2.95 - 3.33), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.4   ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (Fec = 50).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
Nutrients (Ref. 124155):  Calcium = 76.1 [42.5, 172.8] mg/100g; Iron = 0.398 [0.227, 0.755] mg/100g; Protein = 17.1 [15.9, 18.3] %; Omega3 = 0.412 [0.204, 0.836] g/100g; Selenium = 7 [3, 17] μg/100g; VitaminA = 34.8 [8.6, 140.7] μg/100g; Zinc = 0.922 [0.611, 1.358] mg/100g (wet weight);
