how do you move a clam once it attaches?

[fresh]

To tell you the truth, I didn't know that is how you move a clam and I was hoping for something a lot easier and less drastic (on me and on the clam)

I don't think I will be moving the clam after knowing the process.

Now the question that becomes very important: How bad are GSP's for clams? The green stars are touching the clam's shell and the clam is pointed in a way that some stars will be touching the inside of the clam (the meat part). How bad is this and will the clam reposition itself to be in a better location?

I have seen the clam move every once in a while, shift its angle, direction, etc. not too much, but a little.

Thanks all.
