Ross, I found this one article at least by the late Dr. Schilder about animals attaching to cowries. http://www.cowrys.org/archive/NSN096CY.HTM#A I recall at least one other but I'll have to search a bit. For the greatest part, even the Cypraea in surf zones manage to keep their shells free of attaching life forms. However, I have seen images of a barnacle covered over by nacre on a cowry.
