ok I gave the clam an inspection and it appears to have no foot, I can always remember it having one and im not sure what caused the sudden disappearance. the only thing I can think of are my CUC, they have been flipping the clam over on its side and picking at it im not sure why. I also checked my ALK which is at 9. oh and I never ripped the clam of anything it was attached to its in a very deep sand bed so I dont think it ever really had a chance to get its foot down.
