Mystery to me

[FIN&BONEZ]

So I ordered two really nice abalones from UC and this little guy was on the back of one of one of them. Any ideas he almost looks like a baby abalone but not risking it.

No clue. Sump?

If you have some way to look on the shell for the telltale holes, black abalones certainly exist and it would be a shame to get rid of it.

Any antenna or shape/color of a foot? Maybe better focus on the outside of the cup can give you a clue as to what it could be.

Hard to tell since the picture is blurry but his belly and mouth look like a nerite imo

If it is a nerite I’m not sure how they are considered in saltwater but they are very very beneficial to freshwater aquariums
