Please help! something borrowed outside of clam!

[Ralph ATL]

Please!
About an hour ago, I noticed this mucus/debris hanging on the shell of my crocea. It was about a 1/4 inch from the opening on the outside. I didn't think it was anything to worry about, because I figured it was debris that got caught on a ridge. As I looked closer, I saw a few tiny tentacles/antennae or whatever on the clam. Then I realized this bump on the ridge that had 2 openings. This bump was actually shaped like a cow/rhino/powder horn. It was difficult to see because of the ridges & pink calc algae. Both sides has a concealed cover. It was about a little over a 1/4 inch. I used some dental tools & bone scissors & spent 20 minutes breaking it off the shell. I never could find the creature. It had left what appears to be a membrane of the inside of the clam uncovered. NO PICS since I destroyed it ASAP trying to locate creature. I guess it either "took off running" or most likely, borrowed in the clam??????? Any clue?

Advice please!

its a vermetid snail. ugly but harmless. they put out a mucus like web to feed but will cause no harm to your clam

Whew!
should I glue/epoxy over hole in the shell where it appears the inside clam membrane might be visable? or just leave it alone?

Thanks again!

i dont like to kill anything so if it were me i would leave it be. what ever you do dont use epoxy near the clam

looks like this right?

 

[Ralph ATL]

sort of.
The shell of the clam was actually tunnelled or the growth stunted so the shell of the clam looks like it has an indent that is smooth and ........pics coming! give me a minute please!
