Subtidal; lives on the sides of rocks in areas of strongly moving water, such as tidal channels or surf zones, below the lowest low tide level (Ref. 290). Occurs at the low tide mark. 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).
