Associated organisms
Often with its main food, the soft coral Pachyclavularia violacea. This species can incorporate the zooxanthellae living in symbiosis with its prey, and transfer them on the cerata undigested. The zooxanthellae continue to live in symbiosis with the nudibranch, that receive extra nutrition from the photosynthesis products.
