Glaucid sp. from NE Bali, Indonesia

July 12, 2007
From: Lindsay Warren


Dear Bill
While doing a night shore dive off Bali in May last year, I found this specimen which I have not yet been able to identify. Initially I thought it might be a species of Flabellina but on closer inspection can see that, for a start, the rhinophores are completely smooth whereas I believe Flabellina are not. Then Phyllodesmium crossed my mind but I have still had no luck in identifying it. I wonder whether you might be able to shed some light. Is it a type of Glaucid?

Locality: House Reef, Scuba Seraya, Tukad Dabu, not recorded, NE Bali, Indonesia, Tropical Western Pacific, 8 May 2006, Open black sand slope, close to shore but not intertidal, close to low growing reef area. Length: 10 mm. Photographer: Adam Powell.

In one photo one can see some hydroid / anemone type organisms which might be its food but I didn't see it directly feeding on them.

Many thanks for your help.
All the best
Lindsay

Dear Lindsay,

It could be a Flabellina, there are some with smooth rhinophores, but my feeling is that it is a glaucid, perhaps a species of Sakuraeolis. But until someone has a look  at its anatomy we can't really say. The purple line median line and the ceratal colour seem quite distinctive but I can't recall a named species with this colour pattern.

The hydroid-like organism is almost certainly a polychaete tube worm.

Best wishes,
Bill Rudman
