Concerning message #20749:
Dear Dr.Bill,
Here we have two pictures of Thorunna furtiva with sponge. There is always a sponge in their destination.
Can you specify the kind of the sponge by this image?
Locality: Grotto, 10m, Saipan, Northern Mariana Islands, Pacific Ocean, 27 Feb 2010, It was along the wall. Length: 10mm. Photographer: Yuji Fujie.
Best regards,
Yuji

These photos show the sponge somewhat more clearly than in your earlier message. As I suggested in that message, I am pretty sure this is a species of Dysidea. The few records we have on feeding in other species of Thorunna suggest they feed on dysideids. Your record - the first we have on feeding in T. furtiva - supports this idea.
Best wishes,
Bill Rudman
