Double-ringed Flabellina

Flabellina bilas


Also known as Aeolid Nudibranchs and Ringed Flabellina. Found singly or in pairs, feeding on hydroids, coral, sponges and anemones.


Coral and rocky reefs amongst sand and rubble areas, widespread in the Indo-Pacific region.


I believe this nudibranch was laying a ribbon of eggs when I spotted it, at a depth of about 15 meters. It was at a dive spot called Mushroom Rock, in the island of Samal, Davao del Norte.
