Scleractinia, also called stony corals or hard corals, are marine animals in the phylum Cnidaria that build themselves a hard skeleton. The individual animals are known as polyps and have a cylindrical body crowned by an oral disc in which a mouth is fringed with tentacles. Although some species are solitary, most are colonial. The founding polyp settles and starts to secrete calcium carbonate to protect its soft body. Solitary corals can be as much as 25 cm (10 in) across but in colonial species the polyps are usually only a few millimetres in diameter. These polyps reproduce asexually by budding, but remain attached to each other, forming a multi-polyp colony of clones with a common skeleton, which may be up to several metres in diameter or height according to species.
Mussidae is a family of stony coral in the order Scleractinia. Following a taxonomic revision in 2012, the family is now restricted to species found in the Atlantic Ocean, with Pacific species transferred to the new family Lobophylliidae. Many species are referred to as brain coral because their generally spheroid form and grooved surface resembles the convolutions of a brain.
Montipora is a genus of Scleractinian corals in the phylum Cnidaria. Members of the genus Montipora may exhibit many different growth morphologies. With eighty five known species, Montipora is the second most species rich coral genus after Acropora.
The Fungiidae are a family of Cnidaria, commonly known as mushroom corals or plate corals. The family contains thirteen extant genera. They range from solitary corals to colonial species. Some genera such as Cycloseris and Fungia are solitary organisms, Polyphyllia consists of a single organism with multiple mouths, and Ctenactis and Herpolitha might be considered as solitary organisms with multiple mouths or a colony of individuals, each with its separate mouth.
Astreopora is a genus of stony corals in the Acroporidae family. Members of the genus are commonly known as star corals and there are seventeen species currently recognized.
Pavona duerdeni, the porkchop coral, is a coral that forms clusters of cream-colored lobes or discs. They grow in large colonies, divided into ridges or hillocks. The coral is considered to be uncommon due to its low confirmed abundance, yet they are more commonly found in Hawaii, the Indo-Pacific, and the Tropical Eastern Pacific. They make up some of the largest colonies of corals, and have a slow growth rate, as indicated by their dense skeletons. Their smooth appearance is due to their small corallites growing on their surface.
Lobophyllia, commonly called lobed brain coral or lobo coral, is a genus of large polyp stony corals. Members of this genus are sometimes found in reef aquariums.
Pectiniidae was a family of stony corals, commonly known as chalice corals, but the name is no longer considered valid.
Echinopora is a genus of stony corals in the family Merulinidae.
Merulinidae is a family of reef-building stony corals.
Favites 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 and Western Pacific Ocean as far as Japan, the Line Islands and the Tuamotu Islands.
Dipsastraea is a genus of stony corals in the family Merulinidae. Members of this genus are native to the Indo-Pacific region. They are zooxanthellate corals.
Leptoria is a genus of stony corals in the family Merulinidae. Members of this genus are known as brain corals or closed brain corals. They 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 South Central Pacific Ocean.
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.
Oxypora glabra is a species of large polyp stony coral in the family Lobophylliidae. It is a colonial coral with thin encrusting laminae. It is native to the central Indo-Pacific.
Oxypora lacera, the ragged chalice coral or porous lettuce coral, is a species of large polyp stony corals in the family Lobophylliidae. It is a colonial coral which can be submassive, encrusting or laminar. It is native to the western Indo-Pacific.
Echinophyllia is a genus of large polyp stony corals. Members of this genus are colonial corals and are generally foliaceous, usually with very thin leaves. They are native to the Indo-Pacific and are sometimes found in reef aquariums.
Echinophyllia aspera, commonly known as the chalice coral, is a species of large polyp stony corals in the family Lobophylliidae. It is a colonial coral which is partly encrusting and partly forms laminate plates or tiers. It is native to the western and central Indo-Pacific.
Leptastrea is a genus of massive reef building stony corals known primarily from the Indo-Pacific. Although previously assigned to Faviidae, Budd et al. (2012) assigned it to Scleractinia incertae sedis based on phylogenetic results demonstrating the polyphyly of Faviidae.
Lobophyllia costata, common name lobed cactus coral, is a species of large polyp stony coral in the family Lobophylliidae.
