All the genera in this family are colonial, reef-building corals. Skeletal structures are similar to those of
Faviidae but are highly fused, without paliform lobes. The valleys are superficial or may be indistinct because of fan-like spreading or contortions in the ridges. Faviidae and
Trachyphylliidae are the most closely related families.[1]
