Life cycle and mating behavior
परिपक्व अवधि | पुनरुत्पत्ति | मछलीऔ का अंडे देना | Eggs | Fecundity | 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.
