Charles Gravier (zoologist)
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 Somaliland
French Somaliland (; ; ) was a French colony in the Horn of Africa. It existed between 1884 and 1967, at which 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 when the ruler and elders of the Issa clan signed treaties with the French. On March 25, 1885, the French signed a treaty with the Gadabuursi, effectively making them a protectorate of France. 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 Somalis did not sign away any of their land rights; the agreement was meant to protect their land from outsiders with the help of the French. However, after the French sailors of the Le Pingouin vessel were mysteriously killed in Ambado in 1886, the French first blamed the British, then the Somalis, using the incident to lay claim to the entire southern territory.Raph ...

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 that glass sponges are the longest-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 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 skeletons made of glass-like silica spicules, fused to form a lattice. In some glass sponges such as member ...

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, which are surrounded by their colored polyps (part of coral that is alive). Antipatharians are a cosmopolitan order, existing in nearly every oceanic 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 order 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 ...

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 organism ... [...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 in 1922. He devoted much of his life to oceanography, exploration and science. Alongside his expeditions, Albert I's reign oversaw major reforms on political, social, and economic levels, with the Monégasque Revolution leading to the end of absolute monarchy and his promulgation of Constitution of Monaco, a constitution in 1911. Early life Born on 13 November 1848 in Paris, France, the son of Charles III, Prince of Monaco, Prince Charles III (1818–1889), and Antoinette de Mérode, Countess Antoinette Ghislaine de Merode (1828–1864), a Belgian nobility, Belgian noblewoman, maternal aunt of Don (honorific), Donna Maria Vittoria dal Pozzo, Maria Vittoria dal Pozzo, Princess della Cisterna, Dukes of Aosta, Duchess consort of Aosta and List of Spanish consorts, Queen consort of Spain.

Actiniaria
Sea anemones ( ) are a group of predatory marine invertebrates constituting 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 dinoflagella ...

Alcyonaria
Octocorallia, along with Hexacorallia, is one of the two extant classes of Anthozoa. It comprises over 3,000 species of marine and brackish animals consisting of colonial polyps with 8-fold symmetry, commonly referred informally as "soft corals". It was previously known by the now unaccepted scientific names Alcyonacea and Gorgonacea, both deprecated , and by the also deprecated name of Alcyonaria, in earlier times. Its only two orders are Malacalcyonacea and Scleralcyonacea, which include corals such as those under the common names of blue corals, sea pens, and gorgonians (sea fans and sea whips). These animals have an internal skeleton secreted by their mesoglea, and polyps with tipically eight tentacles and eight mesenteries. As is the case with all cnidarians, their complex life cycle includes a motile, planktonic phase (a larva called planula), and a later characteristic sessile phase. Octocorals have existed at least since the Ordovician period, as shown by Maurits Lin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
