Yeah, that's what I thought after moving them. At the time I didn't know they were alive. I thought maybe algae or some encrusting gunk was holding the shells to the rock. After placing them on the sand and noting their movements I figured I should ask for some advice.

Well, they both seem to be moving quite freely, digging in the sand and such, so they don't appear to be damaged. I'll return them to the rock and see if they are happier.
