Allopathes Denhartogi
''Allopathes'' is a genus of corals in the family Antipathidae. It is characterized by several long stems protruding from a short, thick base with spines arranged vertically around the stem. Its polyps are arranged in a single row that run the length of the coral. This genus was initially a subgenus of Cirrhipathes and Stichopathes, although it also displayed similarities to '' Antipathes verticillata''. However, the presence of branched growth forms excludes it from Stichopathes or Cirrhipathes and the unique morphology of its spines meant that it could not be included in Allopathes. Because they seemed to have a combination of characteristics of different genera, the two species in question, '' Allopathes desbonni'' and '' Allopathes robillardi'' were given their own genus. The name comes from the Greek "allos-", meaning "other" and "-pathes", referring to its taxonomic relationship to other genera in Antipathidae Antipathidae is a family of corals in the order Antipathari ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 secrete calcium carbonate to form a hard skeleton. A coral "group" is a colony of very many genetically identical polyps. Each polyp is a sac-like animal typically only a few millimeters in diameter and a few centimeters in height. A set of tentacles surround a central mouth opening. Each polyp excretes an exoskeleton near the base. Over many generations, the colony thus creates a skeleton characteristic of the species which can measure up to several meters in size. Individual colonies grow by asexual reproduction of polyps. Corals also breed sexually by spawning: polyps of the same species release gametes simultaneously overnight, often around a full moon. Fertilized eggs form planulae, a mobile early form of the coral polyp which, when m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antipathidae
Antipathidae is a family of corals in the order Antipatharia, commonly known as black corals. Taxonomy This family contains the following genera according to the World Register of Marine Species: * ''Allopathes'' Opresko & Cairns, 1994 -- 3 species * ''Antipathes'' Pallas, 1766 -- 66 species * ''Cirrhipathes'' de Blainville, 1830 -- 16 species * '' Hillopathes'' van Pesch, 1914 -- 1 species * '' Pseudocirrhipathes'' Bo & al., 2009 -- 1 species * '' Pteropathes'' Brook, 1889 -- 1 species * '' Stichopathes'' Brook, 1889 -- 34 species Image:Antipathes dichotoma1.jpg, ''Antipathes dichotoma'' Image:Cirrhipathes sp - coral-wire-groovy.jpg, ''Cirrhipathes ''Cirrhipathes'' is a genus of black coral from the family Antipathidae.

Polyp (zoology)
A polyp in zoology is one of two forms found in the phylum Cnidaria, the other being the medusa. Polyps are roughly cylindrical in shape and elongated at the axis of the vase-shaped body. In solitary polyps, the aboral (opposite to oral) end is attached to the substrate by means of a disc-like holdfast called a pedal disc, while in colonies of polyps it is connected to other polyps, either directly or indirectly. The oral end contains the mouth, and is surrounded by a circlet of tentacles. Classes In the class Anthozoa, comprising the sea anemones and corals, the individual is always a polyp; in the class Hydrozoa, however, the individual may be either a polyp or a medusa, with most species undergoing a life cycle with both a polyp stage and a medusa stage. In class Scyphozoa, the medusa stage is dominant, and the polyp stage may or may not be present, depending on the family. In those scyphozoans that have the larval planula metamorphose into a polyp, the polyp, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cirrhipathes
''Cirrhipathes'' is a genus of black coral from the family Antipathidae. Coral species in this genus are commonly known as whip or wire corals because they often exhibit a twisted or coiled morphology. In addition to their colorful appearance, with colors ranging from yellow to red passing through blue and green, these species possess a dark skeleton that is characteristic to every black coral. Distribution Commonly found in tropical and subtropical areas, these corals are part of the reefs in the Indian and Pacific oceans, at depths greater than . Long and unbranched, ''Cirrhipathes'' species are attached to coral reefs. Description Like all corals, ''Cirrhipathes'' species are made of and covered by polyps. These polyps are responsible for providing defense and feeding mechanisms in the form of stinging structures known as nematocysts. These structures, which are present in their tentacles, are fired at preys or predators. The characteristic barbed-wire-like appearance of ''Cir ...

Antipathes Verticillata
''Antipathes'' is a genus of coral in the order Antipatharia, composed of black coral (so named for its black skeleton). Distinct features vary greatly within this genus: it contains symmetrically aligned as well as irregularly shaped corals, a range of different colors, and colonies that can be either sparsely branched or closely packed. polyps for these corals have six tentacles that are each lined with stinging cells. Unlike their reef-building cousins, these coral lack photosynthesizing algae and are not restricted to the lighter surface regions. They prefer to live in deeper waters near currents so they can catch and eat passing zooplankton. Species Species included in this genus are: * '' Antipathes aculeata'' (Brook, 1889) * '' Antipathes arborea'' Dana, 1846 * '' Antipathes assimilis'' (Brook, 1889) * '' Antipathes atlantica'' Gray, 1857 * ''Antipathes brooki'' (Whitelegge & Hill, 1899) * ''Antipathes caribbeana'' Opresko, 1996 * ''Antipathes catharinae'' (Pax, 1932) * ...

Cnidarians Of The Atlantic Ocean
Cnidaria () is a phylum under kingdom Animalia containing over 11,000 species of aquatic animals found both in freshwater and marine environments, predominantly the latter. Their distinguishing feature is cnidocytes, specialized cells that they use mainly for capturing prey. Their bodies consist of mesoglea, a non-living jelly-like substance, sandwiched between two layers of epithelium that are mostly one cell thick. Cnidarians mostly have two basic body forms: swimming medusae and sessile polyps, both of which are radially symmetrical with mouths surrounded by tentacles that bear cnidocytes. Both forms have a single orifice and body cavity that are used for digestion and respiration. Many cnidarian species produce colonies that are single organisms composed of medusa-like or polyp-like zooids, or both (hence they are trimorphic). Cnidarians' activities are coordinated by a decentralized nerve net and simple receptors. Several free-swimming species of Cubozoa and Scyph ...
