Maximum Total Length: 7.6 m. Depth: Intertidal (Ref. 290). Habitat: Sides or bottoms of large boulders on open coast (Ref. 315). Occurs on the sides or bottoms of large boulders in the open coast (Ref. 315); mid to low tide zones from Alaska to Point Concepcion (Ref. 312). Herbivorous, preferring diatoms and green alga, e.g., sea lettuce Ulva sp. (Ref. 312). Members of the class Polyplacophora are mostly gonochoric. Life cycle: Eggs hatch into lecitotrophic planktonic trocophore larvae (no veliger stage) which later metamorphose and settle on the bottom as young adults (Ref. 833).
