Bubble Coral
Plerogyra sinuosa, a jelly-like species of the phylum Cnidaria, is commonly known as "bubble coral" due to its bubbly appearance. During the day, these "bubbles" are grape-sized, increasing their surface area to absorb more light. At night, tentacles reach out to capture food, and the bubbles shrink in size. This species requires low light and a gentle water flow. Other names for Plerogyra sinuosa include "grape coral", bladder coral, pearl coral and branching bubble coral. The IUCN reports that this species is found near the coastlines of India and Australia.
