Short description
Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 7 - 9; Mjukstrålar i ryggfenan (totalt) : 13 - 16; Taggstrålar i analfenan: 3; Mjukstrålar i analfenan: 21 - 24; Ryggkotor: 31 - 34. Color variable, olive brown to coppery above lateral line, with dark pigment under each scale, bright below lateral line; dark on axil; fins either pale or rosy (Ref. 6885).
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).
