Sea grapes are widely distributed in tropical and subtropical regions around the world, including the Indo-Pacific, the Red Sea, and the Mediterranean. One of the most intriguing aspects of sea grapes is their edibility, which has sparked interest among marine enthusiasts, chefs, and health-conscious individuals.
