Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Members of the order Nudibranchia are simultaneous hermaphrodites. Mating behavior: Both individuals darts their penis toward each other to induce one to act as a male and the other as the female. The victorious one to penetrate the body wall is the dominant male. Life cycle: Eggs are deposited on a substratum where they develop and hatch into (planktonic) vestigial veliger larval stage and further grow as adults.
