Concerning message #6434:

Dear Bill,
First, congratulations for your spectacular synthesis between Chromodoris cavae and Chromodoris cf geminus [#19876 ]. It's an incredible link!
Then, I spotted a new Aldisa by night, third from Reunion. This specimen appears similar to Aldisa pikokai by Scott Johnson from Oahu, Hawai.

Locality: Etang Salé. Permanent pool, 1 metre, Reunion Island, Indian Ocean, 30 april 2007, Night since one hour. Length: 18 mm. Photographer: Hugues Flodrops.

Thanks for your help.
Regards.
Hugues.

Dear Hugues,
Firstly my views on C. cavae should be treated as 'a work in progress'. I could be wrong, but by assembling all the 'look alikes' together it gives interested locals like you a theory to test. I look forward to further observations.

Concerning your Aldisa. Species of Aldisa do have pits like this in their mantle, which resemble the oscules of sponges, But usually they are not as numerous as this. I have posted some photos of another species with similar mantle pits, Sclerodoris tuberculata [message #19894], which I studied in east Africa. My guess is that your animal could be Sclerodoris, however I think we would need to look at the anatomy to be sure.

Best wishes,
Bill Rudman
