It is rated as a "least-concern species" by the International Union for Conservation of Nature. This species was first described in 1846 as Favia pallida by the American zoologist James Dwight Dana; it was later transferred to the genus Dipsastraea, but some authorities continue to use the original name.

This is an uncommon species of coral and seems to be decreasing in abundance, and the International Union for Conservation of Nature has rated its conservation status as being "near threatened".
Favites pentagona is a species of stony coral in the family Merulinidae, sometimes known as larger star coral. It is native to the Indo-Pacific region and its range extends from the Red Sea through the Indian Ocean to the Western Pacific Ocean. This is a common species throughout its wide range and the International Union for Conservation of Nature has rated its conservation status as being of "least concern".
Goniastrea is a genus of stony corals in the family Merulinidae. Species belonging to the genus Goniastrea forms massive colonies, usually spherical or elongate, with well developed paliform lobes. Polyps can be seen only at night.

Goniastrea favulus, also known as the lesser star coral, is a species of stony coral in the family Merulinidae. It occurs in shallow water in the Indo-Pacific region. This is an uncommon species of coral and the International Union for Conservation of Nature has rated its conservation status as being "near threatened".
Goniastrea retiformis is a species of stony corals in the family Merulinidae. It is native to shallow water in the Indo-Pacific region.

Goniastrea stelligera, commonly known as knob coral, is a species of stony coral in the family Merulinidae. It occurs in shallow water on the coast of East Africa and in the Indo-Pacific region. This is a common species of coral but it seems to be decreasing in abundance. The main threat it faces is from the destruction of its coral reef habitat, and it is also moderately susceptible to coral bleaching, so the International Union for Conservation of Nature has rated its conservation status as being "near threatened".

Hydnophora is a genus of large polyp stony corals in the family Merulinidae.

Hydnophora exesa, also called horn coral or spine coral, is a coral in the genus Hydnophora. It was described by Peter Simon Pallas in 1766.

Merulina is a genus of stony corals in the family Merulinidae. Members of this genus are native to the Indo-Pacific region and their ranges extend from the Red Sea through the Indian Ocean as far as Japan and the southern central Pacific Ocean. Merulina ampliata is the type species.

The open brain coral is a brightly colored free-living coral species in the family Merulinidae. It is the only species in the monotypic genus Trachyphyllia and can be found throughout the Indo-Pacific.

Orbicella annularis, commonly known as the boulder star coral, is a species of coral that lives in the western Atlantic Ocean and is the most thoroughly studied and most abundant species of reef-building coral in the Caribbean to date. It also has a comprehensive fossil record within the Caribbean. This species complex has long been considered a generalist that exists at depths between 0 and 80 meters that grew into varying colony shapes in response to differing light conditions. Only recently with the help of molecular techniques has O. annularis been shown to be a complex of at least three separate species. Those species are divided into O. annularis, O. faveolata, and O. franksi. This coral was originally described as Montastraea annularis.

Orbicella faveolata, commonly known as mountainous star coral, is a colonial stony coral in the family Merulinidae. It is native to the Caribbean Sea and the Gulf of Mexico and is listed as "endangered" by the International Union for Conservation of Nature. This species was formerly known as Montastraea faveolata.

Orbicella franksi, commonly known as boulder star coral, is a colonial stony coral in the family Merulinidae. It is native to shallow waters in the Caribbean Sea, the Gulf of Mexico, the Bahamas, Bermuda and Florida, and is listed as a "vulnerable species" by the International Union for Conservation of Nature.

Oulophyllia is a genus of stony corals in the family Merulinidae. Members of this genus are native to the tropical western and central Indo-Pacific region.

Oulophyllia crispa, sometimes called the intermediate valley coral, is a species of stony coral in the family Merulinidae. It is native to the tropical western and central Indo-Pacific region. Although this coral has a wide range, it is generally uncommon and seems to be decreasing in abundance, and the International Union for Conservation of Nature has rated its conservation status as being "near threatened".

Paragoniastrea is a genus of stony corals in the family Merulinidae.
Paragoniastrea australensis, also known as the lesser star coral, is a species of stony corals in the family Merulinidae. It occurs in shallow water in the Indo-Pacific region.
