Cyerce cristallina from southern France

July 30, 2005
From: Fabien Lombard

I've observed this opisthobranch in Villefranche sur mer (France, Mediterranean Sea) during a night dive at 7 metres depth. I think that it's Cyerce cristallina. I have never seen this species here before, and found no eggs or other specimens. I observed some yellow spots on the cerata but they were not as numerous as in the previous observations from Jim Lyle [message #10855 ]

Dear Fabien,
Villefranche sur mer is a very famous locality, often mentioned by French opisthobranch workers as the source of their specimens.

It is good to get some photos of this beautiful animal from the Mediterranean to compare with Jim Lyle's from Mexico. The yellowish spots are almost certainly glands, so the difference in abundance may just reflect a difference in the physiological cycle of the glands.
Best wishes,
Bill Rudman
