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.
Oxypora glabra is a species of scleractinia coral, otherwise known as stony or hard coral, and part of the family Lobophylliidae, which is characteristic of robust coral colonies. [3] Corals are extremely plastic organisms in that their structures rely on their environment, making construction widely variable.
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.
It is found in the Indo-Pacific [2] and is the most abundant coral species in Xuwen Coral Reef National Nature Reserve. G. astreata is acclimatized to water temperatures ranging from about 27 ± 0.5 °C. [3] It is generally a shallow-water coral and is commonly seen at a depth of around 15 meters. It can range from a depth of 1 meter to 30 ...
Euphylliidae (Greek eu-, true; Greek phyllon, leaf) are known as a family of polyped stony corals under the order Scleractinia. [1] This family consists of multiple genera (more than one genus) and various species which are found among the ocean floor. These coral may be sparse or conspicuous in the wild.
The class includes important coral reef builders such as the stony corals, sea anemones, and zoanthids. The recognized orders are shown below: [4] Actiniaria – sea anemones; Antipatharia – black corals; Corallimorpharia – corallimorpharians aka "false corals" †Rugosa – rugose corals; Scleractinia – stony corals †Tabulata ...
The skeleton of a stony coral in the order Scleractinia is secreted by the epidermis of the lower part of the polyp; this forms a corallite, a cup-shaped hollow made of calcium carbonate, in which the polyp sits. In colonial corals, following growth of the polyp by budding, new corallites are formed, with the surface of the skeleton being ...
