Dendronephthya Hemprichi
''Dendronephthya hemprichi'' is a common soft coral found from Red Sea to Western Pacific. It is usually pink or orange with transparent trunk and it grows up to 70 cm. It exists at 30° N latitude.Dahan, M. & Benayahu, Y. 1993. Reproduction of Dendronephthya hemprichi (Cnidaria: Octocorallia): year-round spawning in an azooxanthellate soft coral. Marine Biology. 129: 573. The smallest unit of this coral, like all other corals, is a polyp. This particular species of the Dendronephthya has the ability to reproduce sexually and asexually through broadcast spawning and clonal propagation, respectively.Dahan, M. & Benayahu, Y. 1997. Clonal propagation by the azooxanthellate octocoral Dendronephthya hemprichi. Coral Reefs. 16: 5. Reproductive Behavior D. hemprichi is gonochoric – sexually binary – with colonies releasing either eggs or sperm. As a broadcasting species, in terms of sexual reproductive ability, it participates in mass spawning events in which the coral releas ...

Carl Benjamin Klunzinger
Carl Benjamin Klunzinger (18 November 1834, in Güglingen – 21 June 1914, in Stuttgart) was a German physician and zoologist. He studied medicine at the Universities of Tübingen and Würzburg, afterwards attending lectures on geology and zoology in Vienna and Prague. In 1862 he traveled to Cairo, where he spent eighteen months learning Arabic. Beginning in February 1864 he worked as a physician at Kosseir, a seaport on the Red Sea. Here he spent five years collecting a vast quantity of fish and other marine specimens. From 1869 he examined his Red Sea collection at the '' Staatliches Museum für Naturkunde Stuttgart'', traveling to Frankfurt and Berlin in order to conduct zoological comparison studies. At Stuttgart he also investigated Australian fish species procured by Ferdinand von Mueller (1825-1896), from whose collection Klunzinger described approximately fifty new species from Australia and New Zealand. In 1872 he was back in Kosseir collecting additional marine s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alcyonacea
Alcyonacea, or soft corals, are an order of corals. In addition to the fleshy soft corals, the order Alcyonacea now contains all species previously known as "gorgonian corals", that produce a more or less hard skeleton, though quite different from "true" corals (Scleractinia). These can be found in suborders Holaxonia, Scleraxonia, and Stolonifera. They are sessile colonial cnidarians that are found throughout the oceans of the world, especially in the deep sea, polar waters, tropics and subtropics. Common names for subsets of this order are sea fans and sea whips; others are similar to the sea pens of related order Pennatulacea. Individual tiny polyps form colonies that are normally erect, flattened, branching, and reminiscent of a fan. Others may be whiplike, bushy, or even encrusting. A colony can be several feet high and across, but only a few inches thick. They may be brightly coloured, often purple, red, or yellow. Photosynthetic gorgonians can be successfully kept in c ...

Red Sea
The Red Sea ( ar, البحر الأحمر - بحر القلزم, translit=Modern: al-Baḥr al-ʾAḥmar, Medieval: Baḥr al-Qulzum; or ; Coptic: ⲫⲓⲟⲙ ⲛ̀ϩⲁϩ ''Phiom Enhah'' or ⲫⲓⲟⲙ ⲛ̀ϣⲁⲣⲓ ''Phiom ǹšari''; Tigrinya: ቀይሕ ባሕሪ ''Qeyih Bahri''; ) is a seawater inlet of the Indian Ocean, lying between Africa and Asia. Its connection to the ocean is in the south, through the Bab el Mandeb strait and the Gulf of Aden. To its north lie the Sinai Peninsula, the Gulf of Aqaba, and the Gulf of Suez (leading to the Suez Canal). It is underlain by the Red Sea Rift, which is part of the Great Rift Valley. The Red Sea has a surface area of roughly 438,000 km2 (169,100 mi2), is about 2250 km (1398 mi) long, and — at its widest point — 355 km (220.6 mi) wide. It has an average depth of 490 m (1,608 ft), and in the central ''Suakin Trough'' it reaches its maximum depth of . The Red Sea also has exten ...

Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .

Artificial Reef
An artificial reef is a human-created underwater structure, typically built to promote marine life in areas with a generally featureless bottom, to control erosion, block ship passage, block the use of trawling nets, or improve surfing. Many reefs are built using objects that were built for other purposes, such as by sinking oil rigs (through the Rigs-to-Reefs program), scuttling ships, or by deploying rubble or construction debris. Other artificial reefs are purpose-built (e.g. the reef balls) from PVC or concrete. Shipwrecks may become artificial reefs when preserved on the seafloor. Regardless of construction method, artificial reefs generally provide hard surfaces where algae and invertebrates such as barnacles, corals, and oysters attach; the accumulation of attached marine life in turn provides intricate structures and food for assemblages of fish. History The construction of artificial reefs began in ancient times. Persians blocked the mouth of the Tigris River to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nephtheidae
Nephtheidae is a family of soft corals in the phylum Cnidaria. Members of this family are known as carnation corals, tree corals or colt soft corals. They are very attractive and show a wide range of rich and pastel colours including reds, pinks, yellows and purples. They are popular with reef aquarium hobbyists. Most of these corals are arborescent and have little knobs on the end of their rubbery branches. The coral polyps tend to retract in the daytime which gives these corals their alternative name of broccoli corals because of their resemblance to the vegetable. At night the polyps emerge and extend their tentacles to feed, looking like little bunches of flowers on the ends of the branches. Genera The World Register of Marine Species includes the following genera in this family: *'' Capnella'' Gray, 1869 *'' Chondronephthya'' Utinomi, 1960 *'' Chromonephthea'' van Ofwegen, 2005 *'' Coronephthya'' Utinomi, 1966 *''Dendronephthya'' Kuekenthal, 1905 *'' Drifa'' Danielssen, 1 ...

Taxa Named By Carl Benjamin Klunzinger
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] |
