Phyllodesmium macphersonae (Burn, 1962)

This genus of aeolids is found only in the topical Indo-Pacific. All species are specialized predators on octocorals. Most species have symbiotic zooxanthellae that are capable of carrying out photosynthesis providing oxygen and nutritional sugar to the animal. This group of aeolids also lacks the ability to store nematocysts, so must depend on other forms of defense.

Phyllodesmium macphersonae is light grey in color with small brownish dots that extend up the base of the cerata, oral tentacles and rhinophores. It can be found on several soft corals.

If you want to see this lovely species come join us at Crystal Blue Resort in Anilao this May for our second annual Nudibranch Festival . There are still a couple of slots open.

Thanks again for sharing David.
