Placida cremoniana from Wollongong, NSW, Australia

Dear Bill,
I found this in a Wollongong rockpool.

Locality: Wollongong, NSW, southeastern Australia, rockpool. About 15 mm long, initally under a rock which was kicked over.  May 2005

Is it a Flabellina?

Dear Sascha,
Although this looks superficially like an aeolid, it is a sacoglossan, much more closely related to Elysia than to Flabellina. This species appears to be identical to the Mediterranean Placida cremoniana. As it is found in many parts of the Indo-West Pacific, this strange distribution is either very ancient, or the result of shipping in the last 200 years.
Best wishes,
Bill Rudman
