Maturity: Lm ? range ? - ? cm Max length : 8.0 cm TL male/unsexed; (Ref. 865)

Life cycle and mating behavior
Maturity | Reproduction | Spawning | 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.
