Charles Joseph Gravier
Charles Joseph Gravier (4 March 1865, in Orléans – 15 November 1937, in Paris) was a French zoologist. He initially taught classes at (1883–85) in Orléans and at the , afterwards becoming a professor of natural history at the (1887) in Grenoble. In 1893 he obtained his aggregation of natural sciences and in 1896 his PhD in sciences. Later he became first assistant to Edmond Perrier (1844–1921) at the in Paris, where from 1903 he served as an assistant to Louis Joubin (1861–1935). In 1917 he attained the chair of zoology (worms and crustaceans) at the museum. Gravier is known for his research of Anthozoa (class containing sea anemones and corals). The genera ''Gravieria'', ''Gravierella'' and ''Gravieropsammia'' are named after him, as are numerous marine species, (list of genera & species) including the Red Sea mimic blenny ('' [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

French Wikipedia
The French Wikipedia (french: Wikipédia en français) is the French-language edition of Wikipedia, the free online encyclopedia. This edition was started on 23 March 2001, two months after the official creation of Wikipedia. It has articles as of , making it the -largest Wikipedia overall, after the English-, Cebuano-, Swedish- and German-language editions, the largest Wikipedia edition in a Romance language. It has the third-most edits, and ranks 6th in terms of depth among Wikipedias. It was also the third edition, after the English Wikipedia and German Wikipedia, to exceed 1 million articles: this occurred on 23 September 2010. In April 2016, the project had 4657 active editors who made at least five edits in that month. In 2008, the French encyclopaedia '' Quid'' cancelled its 2008 edition, citing falling sales on competition from the French edition of Wikipedia.

French Somaliland
French Somaliland (french: Côte française des Somalis, lit= French Coast of the Somalis so, Xeebta Soomaaliyeed ee Faransiiska) was a French colony in the Horn of Africa. It existed between 1884 and 1967, at which time it became the French Territory of the Afars and the Issas. The Republic of Djibouti is its legal successor state. History French Somaliland was formally established in 1896 after the Issa and Afar each signed a treaty with the French, but iterations of what will eventually become French Somaliland existed for few decades prior to the official formation. On March 11, 1862, a treaty signed by Afar Sultan Raieta Dini Ahmet in Paris ceded the territory of Obock for 10,000 thalaris, around 55,000 francs. Later on, that treaty was used by Captain Alphonse Fleuriot de Langle to colonize the south of the Bay of Tadjoura. On March 26, 1885 the French signed another treaty with the Issa making the latter a protectorate under the French. No money changed hands and the ...

Hexactinellid
Hexactinellid sponges are sponges with a skeleton made of four- and/or six-pointed siliceous spicules, often referred to as glass sponges. They are usually classified along with other sponges in the phylum Porifera, but some researchers consider them sufficiently distinct to deserve their own phylum, Symplasma. Some experts believe glass sponges are thlongest-lived animals on earth these scientists tentatively estimate a maximum age of up to 15,000 years. Biology Glass sponges are relatively uncommon and are mostly found at depths from below the sea level. Although the species '' Oopsacas minuta'' has been found in shallow water, others have been found much deeper. They are found in all oceans of the world, although they are particularly common in Antarctic and Northern Pacific waters. They are more-or-less cup-shaped animals, ranging from in height, with sturdy lattice-like internal skeletons made up of fused spicules of silica. The body is relatively symmetrical, with a ...

Antipatharia
Antipatharians, also known as black corals or thorn corals, are an order of soft deep-water corals. These corals can be recognized by their jet-black or dark brown chitin skeletons, surrounded by the polyps (part of coral that is alive). Antipatharians are a cosmopolitan order, existing at nearly every location and depth, with the sole exception of brackish waters. However, they are most frequently found on continental slopes under deep. A black coral reproduces both sexually and asexually throughout its lifetime. Many black corals provide housing, shelter, food, and protection for other animals. Black corals were originally classified in the subclass Ceriantipatharia along with ceriantharians (tube-dwelling anemones), but were later reclassified under Hexacorallia. Though they have historically been used by Pacific Islanders for medical treatment and in rituals, its only modern use is making jewelry. Black corals have been declining in numbers and are expected to continue de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Madreporaria
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 organi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prince Albert I Of Monaco
Albert I (Albert Honoré Charles Grimaldi; 13 November 1848 – 26 June 1922) was Prince of Monaco from 10 September 1889 until his death. He devoted much of his life to oceanography, exploration and science. Alongside his expeditions, Albert I made reforms on political, economic and social levels, bestowing a constitution on the principality in 1911. Early life Born on 13 November 1848 in Paris, France, the son of Prince Charles III (1818–1889), and Countess Antoinette de Mérode-Westerloo (1828–1864), a Belgian noblewoman, maternal aunt of Donna Maria Vittoria dal Pozzo, Princess della Cisterna, Duchess consort of Aosta and Queen consort of Spain. As a young man, Prince Albert served in the Spanish Navy as a navigator. During the Franco-Prussian War, he joined the French Navy where he was awarded the Legion of Honor. In addition to his interest in oceanographic studies, Albert had a keen interest in the origins of man and in Paris, he founded the "''Institute for H ...

Actiniaria
Sea anemones are a group of predatory marine invertebrates of the order Actiniaria. Because of their colourful appearance, they are named after the ''Anemone'', a terrestrial flowering plant. Sea anemones are classified in the phylum Cnidaria, class Anthozoa, subclass Hexacorallia. As cnidarians, sea anemones are related to corals, jellyfish, tube-dwelling anemones, and '' Hydra''. Unlike jellyfish, sea anemones do not have a medusa stage in their life cycle. A typical sea anemone is a single polyp attached to a hard surface by its base, but some species live in soft sediment, and a few float near the surface of the water. The polyp has a columnar trunk topped by an oral disc with a ring of tentacles and a central mouth. The tentacles can be retracted inside the body cavity or expanded to catch passing prey. They are armed with cnidocytes (stinging cells). In many species, additional nourishment comes from a symbiotic relationship with single-celled dinoflagellates, with zooxa ...

Alcyonaria
Octocorallia (also known as Alcyonaria) is a class of Anthozoa comprising around 3,000 species of water-based organisms formed of colonial polyps with 8-fold symmetry. It includes the blue coral, soft corals, sea pens, and gorgonians (sea fans and sea whips) within three orders: Alcyonacea, Helioporacea, and Pennatulacea. These organisms have an internal skeleton secreted by mesoglea and polyps with eight tentacles and eight mesentaries. As with all Cnidarians these organisms have a complex life cycle including a motile phase when they are considered plankton and later characteristic sessile phase. Octocorals have existed at least since the Ordovician period, as shown by Maurits Lindström's findings in the 1970s, however recent work has shown a possible Cambrian origin. Biology Octocorals resemble the stony corals in general appearance and in the size of their polyps, but lack the distinctive stony skeleton. Also unlike the stony corals, each polyp has only eight tentacles, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
