Phidiana indica from Oman

December 19, 2006
From: Jasper Lansink

Hello Bill,

I have some more unknown nudibranchs. In 10 dives I found about 13 species of which around 8 I could determine using your site.

The pictures show 2 variations of the same slug (I think). One has a white body and the base of the cerata is orange, the other one has a full orange body. Both have similar blue and yellow cerata. Possibly there are more varations and is that the reason I could not find the correct species.

Locality: Muscat, Bandar Khairan, 15 meters, Oman, Gulf of Oman, 19 september 2006, Coral, Sea, No currents. Length: 4 cm. Photographer: Jasper Lansink.

Dear Jasper,
This is Phidiana indica. As you'll see in the attached messages, there is quite a bit of colour variation in this species. Since we know very little about the fauna of Oman, when you get a moment I would quite like to see photos of the other species you have seen there. It couold give us some useful information on colour variation and distributions.
Best wishes,
Bill Rudman
