Cypriots or ? (illegals)

Colin

Yarik, this is not a cyprid. Cyprids have a spotted shell and the mantle covers the shell at the bottom. As for what kind of mollusk this is, I can't say; let your namesake try to answer this question.

Jonathon

I think this is a young fissurella sp. Over time, the mantle becomes less wide; as the shell grows, the mantle becomes more rounded, and the upper hole at the top of the shell increases. The color can vary greatly.

non-harmful, cleaner, feeds on encrustations on rocks

As always, Polina Rodionova knows the exact answer:

... and SPS

John

I saw. Apparently, he's drawn to small polyps. I left him a little seriatope - let him recover.
