Commonly known as the Pearl Bubble Coral, Physogyra lichtensteini is distinct due to its fleshy vesicles which are on display throughout the day providing refuge for several marine invertebrates including shrimp.
At night tentacles are extended to trap passing nutrients. This EDGE Coral is widespread and common on most shallow reefs in the Indo-Pacific but is often heavily harvested for the aquarium trade.
