Had these come on on some astraea snails.

So I just bought 5 astraea snails from my LFS that had 3 of these things attached pretty firmly to the shell of the snails. Not sure what to think they are. I pulled them off and put them in a separate cup for now. Thanks in advance.

Prob limpets. I like them.

Got a better picture, still thinking limpets?
