Thanks Ura,

This species has a very distinctive colour pattern. I have included a close-up alongside because it shows the typical shape of the rhinophores with a groove along the outside which draws water into the mantle cavity, which is inside the enclosed shell. At the bottom right of the photo, we can see the opening of the tube-like exhalent siphon which funnels water out of the mantle cavity.

Best wishes,
Bill Rudman
