Biology     Glossary (e.g. epibenthic)

Found among giant kelp, usually up in kelp canopy. Feed on small crustaceans, especially ones that live on kelp. Also a cleaner which picks external parasites from other fishes. Usually occur in large aggregations in summer (Ref. 2850). Viviparous, female carries the developing young (Ref. 205).

Estimates based on models

Preferred temperature (Ref. 123201): 8.4 - 18.3, mean 10.7 °C (based on 229 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01318 (0.00559 - 0.03107), b=3.05 (2.84 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.5   ±0.50 se; based on food items.
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (tm=1).
