Doris ocelligera from Italy

September 8, 2006
From: Cristian Magnani

Dear Bill,
Last May while diving on my usual dive spot, I found a nudibranch I had never seen previously. I think it is a specimen of  Doris ocelligera and wish to add my picture to the forum since this nudibranch is not included in your species list.

Locality: Numana, 12.5 metres, Italy, Adriatic Sea, 20 May 2006, on shipwreck. Length: 25 mm. Photographer: Cristian Magnani.

Best regards

Thanks Cristian,
It's good to add another species to the Forum. Your animal does seem to be Doris ocelligera. I guess the name ocelligera comes from the eye-like tubercles on its mantle. They look a bit like the eyes of a chameleon. However I suspect their real purpose is to look like pores or siphons on a sponge or ascidian colony so as to disguise the slug against predators. It is good to get a photo of the egg ribbon as well.

After looking at your photos, I am pretty sure the unidentified dorid from Tunisia [message #9885] which I tentatively identified as Doris ocelligera, is the same thing.

Best wishes,
Bill Rudman
