Life cycle and mating behavior
Maturity | Reproduction | Spawning | 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.
