What is the orange part on a scallop? I bought some scallops and they have an orange crescent part attached to them which I haven't seen before. Is this part meant to be discarded?
This is called the "roe".  More on wikipedia: Scallop


  Red roe is that of a female, and
  white, that of a male.


It's optional if you want to eat it, personally it don't like the taste.
