Raccoons eat them here also.

I think (but don't know for sure) that clams and mussels are different.

My brother growing up was kind of a river/timber survivalist rat and he would eat about anything just to try it. He said he tried several ways of cooking them and never could get them to taste edible.

I took this word for it and never tried. I have a bunch of probably 5" long or better ones in my pond. They are part of a bird parasite fish life cycle. I don't think clams feature that kind or reproduction. That may be the difference between clams and mussels.
