Hi Bill
Here is another one of the Port Stephens nudis. It is tiny around 20mm long.
Could you please confirm the ID I have for it.

Hi Carol,
It is definitely a species of Gymnodoris. I am pretty sure it is Gymnodoris citrina but there is not enough definition in the photo to be sure. I am at present preparing a paper on the family. With few exceptions, the species of this genus can be described as white with orange spots or lines. They certainly didn't learn about colour from the chromodorids!

When I get that finished I will put up some pictures of different species. The gymnodorid section of the Sea Slug Forum is looking a bit thin at present.

Best wishes,
Bill Rudman
