Hi Bill
My best guess is that this is a juvenile Bornella anguilla. It was less than 1cm, but I think I can see the development of gills along the first cerata.
Locality: Christmas Beach, 12 meters, East Timor, Banda Sea, 25 December 2008, coral reef. Length: 1 cm. Photographer: Brian Francisco.

Dear Brian,
Yes you can see the transparent gills on the inside of the first cerata. As you can see in other photos of larger animals on the Forum , the gills in Bornella anguilla are probably the most developed of any species of Bornella. I have also included a close-up of the rhinophore complex showing how the stalk and sheath have grown to look almost identical to the cerata.
Best wishes,
Bill Rudman
