This is an epibiotic species, found on hard substrata including holdfasts of Macrocystis sp., cobbles encrusted with calcareous red algae and in mussel beds; it is a brooding species that feeds on red and green algae. It is highly sensitive to desiccation and intolerant to high salinities (Ref. 87801).
Life cycle and mating behavior
Γεννητική Ωρίμανση | Αναπαραγωγή | Γεννοβολία | Eggs | Γονιμότητα | 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.
