Isididae
Bamboo coral, family Isididae, is a family of mostly deep-sea coral of the phylum Cnidaria. It is a commonly recognized inhabitant of the deep sea, due to the clearly articulated skeletons of the species. Deep water coral species such as this are especially affected by the practice of bottom trawling. These organisms may be an important environmental indicator in the study of long term climate change, as some specimens of bamboo coral have been discovered that are 4,000 years old. Description Relatively little is known about bamboo coral. The skeletons of bamboo coral are made up of calcium carbonate in the form of tree-like branches alternating with joint-like nodes or axes composed of gorgonin protein. The alternation of the bony structures with the smaller gorgonin parts give the bamboo coral a finger-like appearance similar to that of the bamboo plant on land. Bamboo coral was reported in 2005 to have been found on a dozen seamounts in the Pacific Ocean between Santa Barbar ... [...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] |

Acanella
''Acanella'' is a genus of deep sea bamboo coral of the family Isididae. Acanella are mainly studied and found in Hawaii, they are able to survive in high-flow sites and are preyed upon by nudibranch mollusks. It has a high fecundity and small size that allows high dispersal and recruitment; however, it has been classified as a vulnerable marine organism due to its vulnerability to bottom fishing gear. It contains the following species: *''Acanella africana'' Kükenthal, 1915 *''Acanella arbuscula'' (Johnson, 1862) *''Acanella aurelia'' Saucier & France, 2017 *''Acanella chiliensis'' Wright & Studer, 1889 *''Acanella dispar'' Bayer, 1990 *''Acanella furcata'' Thomson, 1929 *''Acanella gregori'' (Gray, 1870) *''Acanella microspiculata'' Aurivillius, 1931 *''Acanella rigida'' Wright & Studer, 1889 *''Acanella robusta'' Thomson & Henderson, 1906 *''Acanella scarletae'' Saucier & France, 2017 *''Acanella verticillata'' Kükenthal, 1915 *''Acanella weberi ''Acanella'' is a genu ...

Deep Sea
The deep sea is broadly defined as the ocean depth where light begins to fade, at an approximate depth of 200 metres (656 feet) or the point of transition from continental shelves to continental slopes. Conditions within the deep sea are a combination of low temperatures, darkness and high pressure The deep sea is considered the least explored Earth biome, with the extreme conditions making the environment difficult to access and explore. Organisms living within the deep sea have a variety of adaptations to survive in these conditions. Organisms can survive in the deep sea through a number of feeding methods including scavenging, predation and filtration, with a number of organisms surviving by feeding on marine snow. Marine snow is organic material that has fallen from upper waters into the deep sea. In 1960, the bathyscaphe ''Trieste'' descended to the bottom of the Mariana Trench near Guam, at , the deepest known spot in any ocean. If Mount Everest () were submerged there, it ...

Jean Vincent Félix Lamouroux
Jean Vincent Félix Lamouroux (3 May 1779 – 26 March 1825) was a French biologist and naturalist, noted for his seminal work with algae. Biography Lamouroux was born in Agen in the Aquitaine of southwestern France, the son of Claude Lamouroux, an intellectual who made his livelihood in manufacturing, but who was also a musician, a one-term mayor of Agen, and a co-founder of the Academic Society of Agen. Jean Vincent Lamouroux studied botany at the Boudon de Saint-Amans school in Agen. Lamouroux was particularly interested in marine organisms such as algae and hydrozoans. In 1805 he published a dissertation on several species of ''Fucus'' before settling in Paris in 1807, after his father went into bankruptcy. In 1807, Lamouroux was appointed to the French Academy of Sciences and in 1808 he became assistant professor of natural history at the University of Caen, rising to full professorship by 1811. He joined the Linnean Society of Calvados and contributed to its publications, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...
