					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.
