Could anybody help me ID what is on my snail shell. It sort of looks like a half clam/scallop shell that has an orangish/yellowish colour. It's growing as the snail grows and sometimes I think it is lifted up about 1 mm and today I saw my blue damsel take a whack at it and then leave it along. Or maybe if someone can point me to a link with some pics. TIA
