CAY OO13
A Stoplight Parrotfish eats coral presumeably for the meat of the polyps or to scrape the algae off it, but it does manage to ingest a lot of the coral skeleton, and as a result, it passes coral sand. And people worry about diver dammage! Photographed at the site called Round Rock Canyon on Grand Cayman, Cayman Islands, BWI, September, 2000.
