Hi Bill,
Here is a followup to Anne DuPont's earlier message with photos of the Hypselodoris and its sponge. It shows the inflated sac-like oral tube that you mentioned in your update would be visible when they were feeding. I thought you might be interested in seeing the photo.

Dear Linda,
Thanks for this great photo - it certainly shows what I said to look out for if you want evidence of a sponge-feeder at work. Your photo also shows how the yellow lines on the mantle can form a reticulate pattern, reminiscent of H. acriba, at least at the head end of the body. Whether this is a peculiar form of H. acriba or not is an interesting puzzle. I guess it's another little mystery to store up for later investigation. Some photos of intermediate colour forms, or diferent colour forms mating etc, would of course be very welcome.

Best wishes,
Bill Rudman
