Jim,
I realize now that they do open at a slower rate. It’s just not dramatic enough to seem real, and causing the accordion effect mentioned by jroseone. Clams have a fast reflex when they close, kinda like a twitch. I don't think they should close all the way every time, that's not their behavior. But to alleviate the accordion effect, the clams should have a flinching action, much faster than the opening rate. 
I agree.
I think upping the close speed would be suffice in eliminating the issue.
