Thought I'd contribute a picture of what I believe might be a malformed P. nectarea, 26.5mm, on Melithea species. Enjoy.

Dear Wei

What a beautiful shell. Perhaps this animal has changed host from one with red pigment to one with white. Can you tell us anything about it host?

Hi,

Interesting thought! Both pink and white Melithea species were present in the vicinity, but I cannot remember which coloured host it was found on. However, I believe the Phenacovolva are predators and change hosts frequently, so I doubt switching between different coloured hosts will result in such a radical color change in shell.

My gut feel is that the shell colour was a result of an accident or injury. Many injured shells were found at this spot as a result of crashing waves.

Cheers
