Dear Bill,
Thank you for your message. Here is a higher resolution image. Can you confirm the sponge with this image ?

Best regards,

Dear Yuji,
Thanks for higher resolution image. Although the sponge looks as though it could be a species of Dysidea, unfortunately I can't be 100% sure. As I am sure you are aware, one of the problems photographing small animals is that you lose any depth of focus, so, as in this photo, the background is often out of focus.
Thanks again for your help. Perhaps if you find a group of Thorunna again you might like to take a photo focussing on the sponge. It would be good to get a positive identification of the food of this species
Best wishes,
Bill Rudman
