Biology     Glossary (e.g. epibenthic)

Uncommon species (Ref. 34024). Benthic (Ref. 58302). Adults inhabit the body cavity of pearl shells (Pinctada), pen shells (Pinna), and cockles (Laevicardium). Oviparous, with pelagic vexillifer stage larva, and benthic tenuis stage larva (Ref. 36487). Also found in following shells in the Gulf of California: Megapitaria squalida, M. aurantiaca, Laevicardium elatum and Spondylus princeps (Ref. 38407).
