Length at first maturity / Size / Weight / Age
Maturity: Lm ? range ? - ? cm Max length : 30.0 cm SHH male/unsexed; (Ref. 105575)
It is found on hard substrates and shells from the intertidal to a depth of 35 m (Ref. 87801). Sessile and gregarious (Ref. 105577). Omnivorous filter-feeder (Refs. 105577, 106106).
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.
