What's on my Snail?

[pulpfiction]

Just got this snail and it has weird black worm looking things on it. They don't look like theyre moving and are fused partly under the shell. I couldn't scrape them off. Please help identify. Would it be something bad to add to a tank?

I'm not sure, in the pic it just looks like a hole in the shell

Second this. I would super glue over the spots. I had vermetid snails come in on astrena snails and now they are popping up all over my tank.

I will for sure super glue over it.

It's not a hole in the shell. its some weird growth that doesn't move. I can see tiny divits from where maybe more of these black things might have been but fell off.
