Biology     Glossary (e.g. epibenthic)

Intertidal (Ref. 81522); Littoral to sublittoral fringe areas; known as a fouling species (Ref. 81749) - on piers, pontoons, and boat hulls (Ref. 102838). In sheltered (Ref. 125338) to exposed rocky shores. Can be found on the shells of predatory gastropods Reishia clavigera and Cellana toreuma (Ref. 127116). Part of both epibenthic and arboreal communities in mangrove areas (Ref. 128397). Sessile suspension feeder (Ref. 125928).

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.
