Surf-zone to 40 m. Usually found on stony or rocky bottoms (Ref. 290); in the middle intertidal zone from Alaska to Point Conception; North of Santa Barbara; also on rocky shore with heavy wave action (Ref. 312). Herbivorous, feeding primarily on red and green algae and benthic diatoms (Ref. 312).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
