(Species) Catalaphyllia is a monotypic genus of stony coral in the family Euphylliidae from the western Pacific Ocean.

[5] Catalaphyllia can reproduce sexually, but also asexually by budding new branches that drop off to form satellite colonies.

[2] Like most photosynthetic coral, this species hosts zooxanthellae, dinoflagellates that convert sunlight into sugar for energy.

Like a subset of other corals, it also has a "mouth" that it uses to ingest bits of other food gathered by its large tendrils.

[2][4] 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.
