Life cycle and mating behavior
Chín muồi sinh dục | Sự tái sinh sản | Đẻ trứng | Eggs | Sự sinh sản | 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.
