Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 7 - 9; Raggi dorsali molli (totale) : 13 - 16; Spine anali: 3; Raggi anali molli: 21 - 24; Vertebre: 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).
