Phestilla Nudibranch

Phestilla sp


Phestilla is a genus of sea slugs, aeolid nudibranchs, marine gastropod molluscs in the family Tergipedidae. This is probably an undescribed species. At a glance, they looks like corals. What gives them away is their Rhinopores, the 2 whitish horn like structures on their head or when their underbelly are exposed (Pic#2). I found 2 of them under some coral rubbles and one of them was laying eggs (Pic#4). Their eggs are like swirls of white ribbons, glued to the surface of rocks/rubbles. Phestilla nudibranch feeds on corals and are seldom seen during day time.

New Organism to Project Noah. This set of pictures were not taken by me but by a photographer diver that I was guiding during the dive and I asked to copy the pictures he took during the dives and for permission to use/post the spotting.
