This coral has very large, visible polyps. They develop on a large, branching corallite skeleton, each polyp sporting unusually large, long tendrils, and a large, fleshy oral disc. It can come in several colours: fluorescent green, lime green, and brown. ''Catalaphyllia'' can reproduce sexually, but also asexually by budding new branches that drop off to form satellite colonies. Like most

s in the western and central Pacific Ocean, as well as occasionally in the eastern Indian Ocean. Its range extends as far north as Japan, and south to northern Australia. It can be present on both the shallow and midwater parts of a reef, and prefers water that is strongly agitated or exposed to significant currents. It is commonly seated in sandy areas, rather than directly on rocks.
