Sandalolitha robusta is a plate or mushroom coral in the family Fungiidae. This coral is found in the Indo-Pacific region. [2]
Sandalolitha robusta is a large, heavy colonial coral that is free living, not being attached to the substrate. The numerous individual corallites, in which the polyps are embedded, are separate from each other. They are bordered by alternating wide and narrow septa, calcareous ridges which bear serrated spines. The spines on the costae, the ridges which join the septa to other corallites, are minutely spiny. The polyps normally extend their tentacles to feed only at night. [2]
A corallite is the skeletal cup, formed by an individual stony coral polyp, in which the polyp sits and into which it can retract. The cup is composed of aragonite, a crystalline form of calcium carbonate, and is secreted by the polyp. Corallites vary in size, but in most colonial corals they are less than 3 mm (0.12 in) in diameter. The inner surface of the corallite is known as the calyx. The vertical blades inside the calyx are known as septa and in some species, these ridges continue outside the corallite wall as costae. Where there is no corallite wall, the blades are known as septocostae. The septa, costae and septocostae may have ornamentation in the form of teeth and may be thick, thin or variable in size. Sometimes there are paliform lobes, in the form of rods or blades, rising from the inner margins of the septa. These may form a neat circle called the paliform crown. The septa do not usually unite in the centre of the corallite, instead they form a columella, a tangled mass of intertwined septa, or a dome-shaped or pillar-like projection. In the living coral, the lower part of the polyp is in intimate contact with the corallite, and has radial mesenteries between the septa which increase the surface area of the body cavity and aid digestion. The septa, palliform lobes and costae can often be seen through the coenosarc, the layer of living tissue that covers the coenosteum, the part of the skeleton between the corallites.
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.
Oculina is a genus of colonial stony coral in the family Oculinidae. These corals are mostly found in the Caribbean Sea, the Gulf of Mexico and Bermuda but some species occur in the eastern Pacific Ocean. They occur at depths down to 1000 metres.
Fungia is a genus of corals in the family Fungiidae. It is monotypic with the single species Fungia fungites, which is found growing on reefs in the Indo-Pacific.
Pleuractis paumotensis, commonly called plate coral, is a species of stony coral with a single large polyp. Plate coral are commonly kept in marine aquaria.
Lobactis is a genus of plate or mushroom coral in the family Fungiidae. The genus is monotypic with a single species, Lobactis scutaria, that is found in the Indo-Pacific region.
Oculinidae is a family of colonial corals.
Galaxea is a genus of colonial stony corals in the family Euphylliidae. Common names include crystal, galaxy, starburst and tooth coral. They are abundant on reefs in the Indo-Pacific region and the Red Sea. They are found in water less than 20 metres (66 ft) deep and favour turbid sites. They are sometimes kept in reef aquaria.
Galaxea fascicularis is a species of colonial stony coral in the family Euphylliidae, commonly known as octopus coral, fluorescence grass coral, galaxy coral among various vernacular names.
Poritidae is a family of stony corals. Members of the family are colonial hermatypic (reef-building) corals. They are variable in size and form but most are massive, laminar or ramose as well as branching and encrusting. The corallites are compact with very little coenosteum covering the skeleton. The walls of the corallites and the septa are porous. J.E.N. Veron considers the family is not a natural grouping but is a miscellaneous collection of genera that do not fit well elsewhere.
Pseudodiploria strigosa, the symmetrical brain coral, is a colonial species of stony coral in the family Mussidae. It occurs on reefs in shallow water in the West Atlantic Ocean and Caribbean Sea. It grows slowly and lives to a great age.
Pseudodiploria clivosa, the knobby brain coral, is a colonial species of stony coral in the family Mussidae. It occurs in shallow water in the West Atlantic Ocean and Caribbean Sea.
Meandrina meandrites, commonly known as maze coral, is a species of colonial stony coral in the family Meandrinidae. It is found primarily on outer coral reef slopes in the Caribbean Sea and the Gulf of Mexico.
Lobophyllia corymbosa, also known as lobed cactus coral or brain root coral, is a species of large polyp stony coral in the family Lobophylliidae. It occurs on reefs in shallow waters in the Red Sea, off the coast of East Africa, and in other parts of the tropical Indo-Pacific.
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.
Astrangia solitaria, the dwarf cup coral or southern cup coral, is a species of stony coral in the family Rhizangiidae. It is native to shallow water in the western Atlantic Ocean and the Caribbean Sea.
Favites complanata is a species of stony coral in the family Merulinidae, sometimes known as the larger star coral. It is native to the Indo-Pacific region and its range extends from the Red Sea and Indian Ocean to the western and central Pacific Ocean. 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".
Polycyathus muellerae is a small species of coral in the family Caryophylliidae in the order Scleractinia, the stony corals. It is native to the northeastern Atlantic Ocean and the Mediterranean Sea. It is a large polyp, colonial coral and grows under overhangs and in caves as part of an assemblage of organisms suited to these poorly-lit sites.
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.
Heterocyathus aequicostatus is a small species of coral in the family Caryophylliidae in the order Scleractinia, the stony corals. It is native to the Indo-Pacific region. It is a large polyp, solitary, free-living coral and is usually found on soft substrates.
