This may not be the most appealing or romantic name for a Caribbean beach, but it would be accurate. Sand along the shores of St. John are actually finely crushed coral. How did said coral get so finely crushed, you ask? Well, the credit goes to the shiny, rainbow parrot fish. Without his brilliant white and massive denture-looking choppers scraping against the coral for food, St. John would not have the soft lovely stuff we call sand. Not all sand is fish poo, either, so this is some truly extraordinary excrement. Fish poo… who knew?
