From: Erwin Koehler

Dear Bill,
Here is a shot of a feeding Nembrotha cristata from the Philippines, Balicasag Island. During this dive I saw 4 Nembrotha cristata, 5 Nembrotha milleri and 4 Nembrotha kubaryana. Almost all of them feeding on the same kind of ascidian.

Size 74mm
Depth 17 m

Thanks Erwin,
I have also included a closeup of the gills, not so much to show the gills, but to show the two papillae in the centre of the gill 'circle'. The larger one is the anus, and the smaller one just to the left in the photo (but just anterior in real life) is the kidney opening. The kidney opening is usually very difficult to see in living animals.
Besy wishes,
Bill Rudman
