Biology     Glossary (e.g. epibenthic)

Occurs in intertidal and to 40 m (Ref. 96339). Found among rocks with large seaweeds, often in kelp. Young occur in schools while adults are solitary. Feeds on small crustaceans, mollusks and small fishes. Female attaches eggs to seaweeds, male guards them.

Estimates based on models

Phylogenetic diversity index
(Ref. 82804) 		PD50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight a=0.00513 (0.00235 - 0.01120), b=3.07 (2.87 - 3.27), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level
(Ref. 69278) 		3.9   ±0.62 se; based on food items.
Generation time 4.4 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience
(Ref. 120179) 		Medium, minimum population doubling time 1.4 - 4.4 years (tm=1.25; tmax=4).
Fishing Vulnerability
(Ref. 59153) 		Moderate vulnerability (41 of 100). 🛈
