Why would a clam drop its threads?

One of my crocea also did this. It was anchored under the sand for about a year and recently started moving, then just tipped over. I noticed it was no longer attached. I moved it to another spot on the sand, and it now lays on its side. No byssal threads now. It is opened, though.

My other crocea (a bit smaller, maybe 4") now has been moving on his rock from his original place. He now is near the edge of the rock, and on his side. I am afraid he will soon fall to the sand and I won't be here (leaving town for a week.) Should I do something?

Thanks!!
