Why do we eat only the adductor muscle of the scallop, and not the whole animal?

Answer 1

A) Because that’s the part that tastes good

B) Because the remainder is mostly organs, which can contain some toxic stuff in filter feeders like scallops

That being said, there are cultures that put the whole animal in soups.
