Oculinidae
Oculinidae is a family of colonial corals. Characteristics Members of the family Oculinidae are characterised by having the walls of the corallites (the cups which house the polyps) being composed of solid walled though rather fragile tubes connected by a smooth skeletal material called coenosteum. The corallites are widely spaced and robust. The septa (ridges on the corallite walls) curve noticeably outward giving the coral a spiky appearance. Many species in this family form a symbiotic relationship with the flagellate protozoa zooxanthellae which live within the tissues of the polyps. These are photosynthetic algae that provide nutrients for the polyps while themselves benefiting from a safe environment and an elevated, sunny position. Wet Web Media.com. Retrieved 2011-12-15. ...

Oculina Varicosa
''Oculina varicosa'', or the ivory bush coral, is a scleractinian deep-water coral primarily found at depths of 70-100m, and ranges from Bermuda and Cape Hatteras to the Gulf of Mexico and the Caribbean. ''Oculina varicosa'' flourishes at the Oculina Bank off the east coast of Florida, where coral thickets house a variety of marine organisms. The U.S. National Marine Fisheries Service considers ''Oculina'' a genus of concern, due to the threat of rapid ocean warming. Species of concern are those species about which the U.S. Government's National Oceanic and Atmospheric Administration (NOAA), National Marine Fisheries Service, has some concerns regarding status and threats, but for which insufficient information is available to indicate a need to list the species under the U.S. Endangered Species Act (ESA). While ''Oculina'' is considered a more robust genus in comparison to tropical corals, rising ocean temperatures continue to threaten coral health across the planet. Specie ...

Madrepora
Madrepora (Spanish, "mother of pores") is a genus of stony corals, often found forming reefs or islands in tropical locations. The names Madrepore and Madreporaria were formerly applied universally to any stony coral of the family Scleractinia. They reproduce in three separate ways, as discovered by the marine zoologist Anne Thynne (1800–1866). It is commonly known as horn coral. A colony is branched with small polyps in cylindrical cups separated by a perforated coenosteum. Terminal polyps bear six tentacles, while lateral polyps bear twelve tentacles. Madrepora is economically important, since it contributes to the formation of coral reefs. Species Species include: * '' Madrepora arbuscula'' (Moseley, 1881) * '' Madrepora astroites'' Forskål, 1775 * '' Madrepora carolina'' (Pourtalès, 1871) * '' Madrepora minutiseptum'' Cairns & Zibrowius, 1997 * ''Madrepora oculata'' Linnaeus, 1758 Events January–March * January 1 – Swedish biologist Carl Linnaeus ( ...

Scleractinia
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 polyp (zoology), 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 Colony (biology), colonial. The founding polyp settles and starts to secrete calcium carbonate to protect its soft body. Solitary corals can be as much as 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 cloning, clones with a common skeleton, which may be up to several metres in diameter or height according to species. The shape and appearance of each coral colony depends not only on the species, but also on its location, depth, the amount of water movement and other factors. Many shallow-water co ...

Septum (coral)
In coral Corals are 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 sec ...s, a septum (plural septa) is one of the radiating vertical plates lying within the corallite wall. Outside the corallite wall these plates are known as costae (singular costa). The septa may be thick, thin or vary in size. They may have teeth which range from needle-like to blade-like and are often characteristic of different genera. References {{reflist Cnidarian anatomy ...

Coenosteum
In corals, the coenosteum is the stony skeletal material secreted by the coenosarc, the layer of living material lying between the corallites (the stony cups in which the polyps sit). The coenosteum is composed of aragonite Aragonite is a carbonate mineral, one of the three most common naturally occurring crystal forms of calcium carbonate, (the other forms being the minerals calcite and vaterite). It is formed by biological and physical processes, including prec ..., a crystalline form of calcium carbonate, and is generally a spongy, porous material. Sometimes the coenosteum has ornamentation such as ridges and beads, visible as raised areas of the coenosarc. The coenosteum and corallites together are known as the corallum.

Taxa Named By John Edward Gray
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...
