Plerogyra sinuosa is a coral species of the phylum Cnidaria. It is commonly called "bubble coral" due to its bubbly appearance. The "bubbles" are grape-sized which increase their surface area according to the amount of light available: they are larger during the day, but smaller during the night, when tentacles reach out to capture food. This species requires low light and a gentle water flow. Common names for Plerogyra sinuosa include "grape coral", bladder coral, and pearl coral. According to the IUCN, Plerogyra sinuosa ranges from the Red Sea and Madagascar in the western Indian Ocean to Okinawa and the Line Islands in the Pacific.
