Life cycle and mating behavior
Γεννητική Ωρίμανση | Αναπαραγωγή | Γεννοβολία | Eggs | Γονιμότητα | Larvae
Members of the superorder Thoracica are mostly hermaphroditic. Broadcast spawners, fertilization occurs in the mantle cavity. Life cycle: Eggs hatch into planktonic nauplii and leave the mantle cavity. Afterwards, they undergo six naupliar instars succeded by nonfeeding cypris larva (settling stage) which later metamorphose into adults.
