Corals are colonial marine invertebrates within the class Anthozoa of the phylum Cnidaria. They typically form compact colonies of many identical individual polyps. Coral species include the important reef builders that inhabit tropical oceans and secrete calcium carbonate to form a hard skeleton.
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.
Acanthastrea echinata, commonly known as the starry cup coral, is a species of corals in the family Lobophylliidae. It is a wide-ranging species found from the western Indian Ocean, throughout the Pacific Ocean, and eastward to the southeastern Atlantic Ocean. It can inhabit any reef habitat to depths of 50 m. This species, which may become threatened with the global decline of coral reefs, is a popular coral used in aquariums.
Pocillopora meandrina, commonly known as Cauliflower coral, is a species of coral occurring in the Indo-Pacific and Pacific oceans. This coral lives in shallow reef environments.
Pocillopora is a genus of stony corals in the family Pocilloporidae occurring in the Pacific and Indian Oceans. They are commonly called cauliflower corals and brush corals.
Acroporidae is a family of small polyped stony corals in the phylum Cnidaria. The name is derived from the Greek "akron" meaning "summit" and refers to the presence of a corallite at the tip of each branch of coral. They are commonly known as staghorn corals and are grown in aquaria by reef hobbyists.
Scolymia, commonly called scoly coral, is a genus of large-polyp stony corals (Scleractinia). These animals are believed date back to the Miocene with three extant species present in the eastern Atlantic Ocean.
Ctenella is a monotypic genus of stony coral in the family Euphylliidae. It is represented by a single species, Ctenella chagius. These corals are massive in size with meandering valleys between the calyces which have solid, non-porous walls and fine, evenly spaced, solid septae. They are found in the Indian Ocean, Red Sea and Mediterranean Sea. It forms solid, smooth hemispherical domes and is found in the Indian Ocean in the vicinity of the Chagos Archipelago.
Lobophyllia hemprichii, commonly called lobed brain coral, lobed cactus coral or largebrain root coral, is a species of large polyp stony coral in the family Lobophylliidae. It is found in the Indo-Pacific Ocean. In its specific name Christian Gottfried Ehrenberg honoured his late partner the Prussian naturalist Wilhelm Hemprich; they were among the first to study the marine life of the Red Sea.
Cynarina lacrymalis is a species of stony coral in the family Lobophylliidae. It is variously known as the flat cup coral, solitary cup coral, button coral, doughnut coral, or cat's eye coral. It is found in the western Indo-Pacific Ocean and is sometimes kept in reef aquaria.
Euphyllia cristata is commonly called Grape coral. E. cristata is a kind of stony or hard coral in the family Euphylliidae; it also belongs to the genus Euphyllia in the order of Scleractinia. E. cristata has a wide range of distribution throughout the tropical waters of the Indo-West Pacific area with a large presence in Indonesia. However, despite this large range of distribution, E. cristata has a slightly lower abundance compared to other species, making them a little more uncommon to find. They are typically found in shallow waters from 1–35 meters deep.
Catalaphyllia is a monotypic genus of stony coral in the family Euphylliidae from the western Pacific Ocean. It is represented by a single species, Catalaphyllia jardinei, commonly known as elegance coral. It was first described by William Saville-Kent in 1893 as Pectinia jardinei.
Micromussa regularis is a species of coral found in Indo-Pacific waters from Australia to the western Pacific Ocean. It is usually uncommon throughout its range, but can be more common locally. It has a narrow depth range, and so is susceptible to coral bleaching and disease. It is also threatened by the global decline in coral reef habitats.
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".
Seriatopora hystrix is a species of colonial stony coral in the family Pocilloporidae. It forms a branching clump and is commonly known as thin birdsnest coral. It grows in shallow water on fore-reef slopes or in sheltered lagoons, the type locality being the Red Sea. It is native to East Africa, the Red Sea and the western Indo-Pacific region. It is a common species and the International Union for Conservation of Nature has assessed its conservation status as being of "least concern".
Heliofungia actiniformis is a solitary species of mushroom coral, a large polyp stony coral in the family Fungiidae. This coral is found in shallow water in the Indo-Pacific region. It is a zooxanthellate species. It is a popular coral in the reef aquarium trade; wild populations are threatened by disease, climate change, and over-collecting, and the species is considered vulnerable by the IUCN.
Euphylliidae are known as a family of polyped stony corals under the order Scleractinia.
Pavona maldivensis is a species of colonial stony coral in the family Agariciidae. It is found on shallow reef slopes, particularly those with strong wave action, and on vertical surfaces, in tropical parts of the Indian and Pacific Oceans.
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.
