Co-occurs with Nodolittorina pyramidalis pascuensis and Nerita morio on upper intertidal rocks. Smaller individuals are found in crevices and are associated with Tesseropora sp. and Euraphia devaneyi (Ref. 87916). 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 (Ref. 833).
