Halomitra

Halomitra is a genus of stony corals within the family Fungiidae, commonly known as mushroom corals. Unlike many reef-building corals that are fixed and colonial, Halomitra species are typically solitary and free-living, meaning they are not permanently attached to the reef substrate. Instead, they rest on sandy or rubble seabeds and exhibit limited movement. This makes them particularly well adapted to unstable reef environments such as lagoon floors and sediment-rich reef flats. The most well-known species, Halomitra pileus, is notable for its relatively large size and dome-like shape, often resembling a bowl or mushroom cap. They are most commonly found in regions with warm, clear waters that support coral reef development.
