Parasite lives on shark eyeballs

The Parasite of the Day: Ommatokoita elongata, a dangly, tassel-like creature that attaches itself to the eyeballs of sharks. Supposedly, this does not especially bother the sharks. Is there a German word for "something that gives other people the screaming heebie-jeebies, but about which the person actually affected does not care"? (Via hectocotyli)
