Life cycle and mating behavior
পরিপক্কতা | প্রজনন | ডিম ছাড়া | Eggs | ডিম্বধারন ক্ষমতা | 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.
