Agariciidae
The Agariciidae are a family of reef-building stony corals. This family includes cactus corals, plate corals, and lettuce corals. Members of the family include symbiotic algae called zooxanthellae in their tissues which help provide their energy requirements.

Dactylotrochus
''Dactylotrochus'' is a genus of large polyp stony corals from the Red Sea and western Pacific Ocean. It is monotypic with a single species, ''Dactylotrochus cervicornis''. It inhabits the deep sea and is believed to be azooxanthellate. Description Dactylotrochus cervicornis is a sturdy solitary coral with a short pedicel measuring 15 millimeters (0.6 in) in diameter and an encrusting base. The maximum size is in diameter and high. The fossa (central depression) is elongated and the calyx is deep. As the coral grows, certain parts of the corallite wall and septa develop more than others and two or more petal-like lobes grow, often recurving. The septa are very numerous; they are narrow except near the corallite wall and there is no central columella. Taxonomy This species was originally classified in the family Caryophylliidae but phylogenetic studies show that it should be included in Agariciidae, even though other members of this family are shallow water, colonial corals.

Pavona Duerdeni
''Pavona duerdeni'', the porkchop coral, is a coral that forms clusters of cream-colored lobes or discs.Fenner, Douglas. 2005. Corals of Hawaii: A field guide to the hard, black, and soft corals of Hawaii and the Northwest Hawaiian Islands, including Midway. They grow in large colonies, divided into ridges or hillocks. The coral is considered to be uncommon due to its low confirmed abundance, yet they are more commonly found in Hawaii, the Indo-Pacific, and the Tropical Eastern Pacific. They make up some of the largest colonies of corals, and have a slow growth rate, as indicated by their dense skeletons. Their smooth appearance is due to their small corallites growing on their surface. Characteristics Appearance ''Pavona duerdeni'' is usually a uniform grey color, having yellow and brown coloration on the surface of the coral. The coral receives its coloration from the aggregation of the yellow-brown symbiotic ''zooxanthellae'' on its hard, lobe-shaped structure. The d ...

Agaricia
''Agaricia'' is a genus of colonial stony corals in the family Agariciidae. These corals are found in shallow waters of the West Indies. Characteristics Corals in this genus have several different forms but are usually massive, leaf-like or plate-like. Members of the genus are distinguished from other corals by having no walls to the corallites but having clearly delineated septocostae that connect each corallite to its neighbours. Species The World Register of Marine Species recognises the following species: *'' Agaricia agaricites'' (Linnaeus, 1758) *'' Agaricia fragilis'' Dana, 1846 *'' Agaricia grahamae'' Wells, 1973 *'' Agaricia humilis'' Verrill, 1901 *'' Agaricia lamarcki'' Milne Edwards & Haime, 1851 *''Agaricia tenuifolia ''Agaricia tenuifolia'', commonly known as thin leaf lettuce coral, is a species of colonial stony coral in the family Agariciidae. This coral is found in shallow waters in the Caribbean Sea and Gulf of Mexico. Description In sheltered waters, .. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pavona (coral)
''Pavona'' is a genus of colonial stony corals in the family Agariciidae. These corals are found in shallow waters in the Indo-Pacific region. Characteristics Corals in this genus have a range of different forms including those that are massive, meandering, columnar, leaf-like, and plate-like. A single species may vary in form according to the current, wave action, lighting conditions, and depth of its location. Members of the genus are distinguished from other corals by having no walls to the corallites, but having clearly delineated septocostae that connect each corallite to its neighbours, giving a flower-like pattern on the surface of the coral. The corallites themselves are shallow depressions with central columella and may be separated by ridges. The polyps, with the exception of '' Pavona explanulata'', are only extended at night. The foliose and plate-like forms tend to be two-sided. If they do not get enough nutrients or “food” from photosynthesis they switch t ...

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 ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...
