From Wikipedia:
“Reproduction and Development
Hermaphroditic; ‘Corella willmeriana‘ breeds throughout the year. The eggs are fertilized in the atrial chamber, where they develop in to the free-swimming tadpole stage before released. Swimming larvae remain juveniles for <2 days before anterior adhesive organs allow for attachment to substratum. This triggers metamorphism, which entails enlargement of pharynx for filter feeding; the notochord is sucked back into body and is no longer present in adult form.”
