Anomastraea
''Anomastraea'' is a monotypic genus of corals in the family Coscinaraeidae. It is represented by a single species, the crisp pillow coral (''Anomastraea irregularis''). Description The crisp pillow coral forms small, mound-like colonies that grow to be about 20 cm in height and make a blue-grey and cream color. Like other corals that form colonies, it consists of soft, little polyps that are assisted with small tentacles that guide food in the water to the coral's mouth. The polyps discharge a skeleton known as corallite which would participate in the formation of coral reefs. The corallites establish an uneven honey-comb pattern. As a member of the family Siderastreidae, it is a zooxanthellate, living in harmony with zooxanthellae, a unicellular algae, which aids the coral in its growth and survival. The coral protects the algae with its tissue as the algae helps the host with energy and nutrients, as well as removing metabolic waste. However, the crisp pillow coral is re ...

Horastrea
''Horastrea'' is a monotypic genus of stony coral in the family Coscinaraeidae. It is represented by the single species ''Horastrea indica'', the blister coral. It is native to the southwestern Indian Ocean where it is found in shallow water sandy reefs. It was first described by M Pichon in 1971. It is an uncommon coral and the International Union for Conservation of Nature has assessed it as being a "vulnerable species". Description ''H. indica'' forms massive solid colonies, usually hemispherical in shape. The individual corallites, the stony cups in which the polyps sit, are plocoid (surrounded by a wall) in smaller colonies, becoming meandroid (several corallites inside a valley) in larger ones. There are three cycles of septa (stony ridges) inside the calyx and these continue as well-developed costae between the corallites. This is a zooxanthellate species containing microscopic symbiotic algae in the tissues which supplement the nutritional needs of the colony. This giv ...

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 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 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. 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 corals contain symbiont unicellular organism ... [...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 opi ...

World Register Of Marine Species
The World Register of Marine Species (WoRMS) is a taxonomic database that aims to provide an authoritative and comprehensive list of names of marine organisms. Content The content of the registry is edited and maintained by scientific specialists on each group of organism. These taxonomists control the quality of the information, which is gathered from the primary scientific literature as well as from some external regional and taxon-specific databases. WoRMS maintains valid names of all marine organisms, but also provides information on synonyms and invalid names. It is an ongoing task to maintain the registry, since new species are constantly being discovered and described by scientists; in addition, the nomenclature and taxonomy of existing species is often corrected or changed as new research is constantly being published. Subsets of WoRMS content are made available, and can have separate badging and their own home/launch pages, as "subregisters", such as the ''World List ...
