Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Members of the class Polyplacophora are gonochoric. No copulation; males release sperm throught their respiratory currents and females shed the eggs into the sea. Eggs develop into lecithotrophic planktonic trochophore (Ref. 833). First reproduction occurs when individuals have reached the age of two (years) (Ref. 94892). In the Red Sea, spawning occurs during autumn (Ref. 98877).
