Looks like a ring of eggs to be honest. Maybe a snail or a nudibranch species?

Ah, that's what I was thinking... that it was a macroshot. It's an egg capsule, IMO, and you got a super tight shot of one.

If you take the picture from further back, we might be able to tell what it's from or if it's something different.

I am wondering if the unknown are Bryozoans. (not my image).
