I bought a crayfish today and while I was watching it I noticed that the sides of the head have what looks like light colored growths all over the areas that would be the "cheeks" if the animal had them. Little white structures, about .5mm wide and 2mm long. They're roughly symmetrical, and I have it in quarantine right now.
Is this part of the crayfish, or is this some sort of parasite/disease?
