Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 16 - 17; Raggi dorsali molli (totale) : 18 - 21; Spine anali: 3; Raggi anali molli: 6 - 9; Vertebre: 34 - 35.
This species is most abundant littoral species on the coast of central Chile, found in close association with the brown kelp Lessonia trabeculata. Juveniles found in tidepools to a maximum size of 15.7 cm TL and an estimated 3 years of age, adults occur subtidally. It is mainly herbivorous, feeding almost exclusively on brown, red and green algae, with a strong preference for green and red algae (digestion by acid hydrolysis). Its meat reported as an excellent pan-fish, with rich, white, sweet, and flaky meat (Ref. 86913).
