Dear Bill,
Here are photos of an animal which may be different from those in my message 1; message 3; message 4. They were found at the same place.

date: 10 Jul 2003
place: Kurasaki beach, Amami Ooshima Islands, Kagoshima, Japan
size about: 6 mm
depth: 1 m
temperature: 28 C

Best Regards,

Thanks Jun,
Although on first sight these look different, the blue patch on the back of the head, and the trace of white on the pericardium suggest to me that these are the same as those in your other messages. Which adds a pink parapodial border to the list of characters which this species may or may not have. In the upper photo you can see the black specks surrounded by the clear ring found in some of the other photos.

I suspect the photos in your message 1; message 3; message 4 and message 5 all represent a single species. It can have any of the following characteristics:
• a white patch on the pericardium
• medio-dorsal blue patch behind rhinophores
• pink margin to parapodia
• 3 lobes to parapodia
• black ocelli-like spots
• many papillae on parapodia and body.

I suspect Nishina Masayoshi's photos [message 1, message 2] from Japan, and Julie Marshall's from heron Island [message 1, message 2] are also the same.

Whether E. tomentosa falls into this species or whether it is a second species, I am not sure. I look forward to comments form Kathe Jensen and others
Best wishes,
Bill Rudman
