Maturity: Lm ? range ? - ? cm Max length : 5.0 cm BL male/unsexed; (Ref. 96598)
Epibiotic (Ref. 111011). Commonly found attached to dorsal fins, pectoral flippers, and flukes of a variety of cetacean species; more abundant on hosts studied further from the shoreline (>2 km); associated as commensals (Ref. 96597); or may be termed as phoresy. Does feed on its host but filters plankton with its cirri (Ref. 96598). A suspension feeder. Peak seasonal abundance at water temperatures between 14° - 23° C. Undergoes self-fertilization and larvae is released in the water column where they develop and eventually settle unto a host. Life cycle reported at 5 to 6 months (Ref. 96597).
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.
