Large and slightly depressed species that reaches 55mm in length and 35 mm width. The surface of the valves are usually worn and obliterating the structure. Juveniles are bluish green and the valves are covered with irregular, flattened, subgranulose, zigzag ridges. The girdle is covered with irregular, bluntly pointed spines that have a chitinous base and a calcareous upper part, where the tip is reddish brown.
Found attached on rocks (Ref. 87884), or in sea urchin boreholes (Ref. 90219).
Life cycle and mating behavior
половая зрелость | размножение | нерест | Eggs | Fecundity | Larvae
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.
