Edgard Hérouard
Edgard Joseph Émile Hérouard (18 March 1858 in Saint-Quentin, Aisne - 22 March 1932 in Paris) was a French marine biologist. In 1889 he started work as a préparateur at the University of Paris, Sorbonne, earning his doctorate in natural sciences during the following year. From 1895 he served as ''chef des travaux pratiques de zoologie''. In 1901 he was named vice-president of the Société zoologique de France, and soon afterwards was appointed assistant director of the Station biologique de Roscoff. In 1910 he attained the title of associate professor, becoming a professor "without chair" in 1921. Hérouard is known for his investigations of sea cucumbers, providing descriptions of numerous Holothurian species. Also, with Yves Delage (1854-1920), he is credited with describing the Order (biology), Order Hymenostome, Hymenostomatida (1896). Selected writings * ''Recherches sur les holothuries des côtes de France'', 1889 * ''De l'excrétion chez les Holothuries'', 1895 * ''Tr ...

Saint-Quentin, Aisne
Saint-Quentin (; pcd, Saint-Kintin; nl, label=older Dutch, Sint-Kwintens ) is a city in the Aisne department, Hauts-de-France, northern France. It has been identified as the ''Augusta Veromanduorum'' of antiquity. It is named after Saint Quentin of Amiens, who is said to have been martyred there in the 3rd century. Administration Saint-Quentin is a sub-prefecture of Aisne. Although Saint-Quentin is by far the largest city in Aisne, the capital is the third-largest city, Laon. Mayors The mayor of Saint-Quentin is Frédérique Macarez, a member of the centre-right LR Party. History The city was founded by the Romans, in the Augustean period, to replace the ''oppidum'' of Vermand (11 km away) as the capital of ''Viromandui'' (Celtic Belgian people who occupied the region). It received the name "''Augusta Viromanduorum''", ''Augusta'' of the ''Viromandui'', in honor of the emperor Augustus. The site is that of a ford across the River Somme. During the late Roman pe ...

Marine Biologist
Marine biology is the scientific study of the biology of marine life, organisms in the sea. Given that in biology many scientific classification, phyla, family (biology), families and genera have some species that live in the sea and others that live on land, marine biology classifies species based on the environment (biophysical), environment rather than on taxonomy (biology), taxonomy. A large proportion of all life, life on Earth lives in the ocean. The exact size of this ''large proportion'' is unknown, since many ocean species are still to be discovered. The ocean is a complex three-dimensional world covering approximately 71% of the Earth's surface. The habitats studied in marine biology include everything from the tiny layers of surface water in which organisms and abiotic items may be trapped in surface tension between the ocean and atmosphere, to the depths of the oceanic trenches, sometimes 10,000 meters or more beneath the surface of the ocean. Specific habitats incl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Natural Sciences
Natural science is one of the branches of science concerned with the description, understanding and prediction of natural phenomena, based on empirical evidence from observation and experimentation. Mechanisms such as peer review and repeatability of findings are used to try to ensure the validity of scientific advances. Natural science can be divided into two main branches: life science and physical science. Life science is alternatively known as biology, and physical science is subdivided into branches: physics, chemistry, earth science, and astronomy. These branches of natural science may be further divided into more specialized branches (also known as fields). As empirical sciences, natural sciences use tools from the formal sciences, such as mathematics and logic, converting information about nature into measurements which can be explained as clear statements of the " laws of nature". Modern natural science succeeded more classical approaches to natural philosophy, ... [...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. As of , there are users, admins and files on the French Wikipedia. On 2 December 2014, the French-l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Cucumber
Sea cucumbers are echinoderms from the class Holothuroidea (). They are marine animals with a leathery skin and an elongated body containing a single, branched gonad. Sea cucumbers are found on the sea floor worldwide. The number of holothurian () species worldwide is about 1,717, with the greatest number being in the Asia-Pacific region. Many of these are gathered for human consumption and some species are cultivated in aquaculture systems. The harvested product is variously referred to as '' trepang'', ''namako'', ''bêche-de-mer'', or ''balate''. Sea cucumbers serve a useful role in the marine ecosystem as they help recycle nutrients, breaking down detritus and other organic matter, after which bacteria can continue the decomposition process. Like all echinoderms, sea cucumbers have an endoskeleton just below the skin, calcified structures that are usually reduced to isolated microscopic ossicles (or sclerietes) joined by connective tissue. In some species these can sometim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Yves Delage
Yves Delage (13 May 1854 – 7 October 1920) was a French zoologist known for his work into invertebrate physiology and anatomy. He also discovered the function of the semicircular canals in the inner ear. He is also famous for noting and preparing a speech on the Turin Shroud, arguing in favour of its authenticity. Delage estimated the probability that the image on the shroud was not caused by the body of Jesus Christ as 1 in 10 billion. Life He was born in Avignon on 13 May 1854. He became the director of the Station Biologique de Roscoff in 1901. From 1902 he was Professor of Zoology at the Sorbonne University in Paris. Delage performed influential experiments on the fertilization of sea urchin egg. Delage was a critic of Darwinism. He argued for a version of neo-Lamarckism.Loison, Laurent. (2006).

Order (biology)
Order ( la, wikt:ordo#Latin, ordo) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between Family_(biology), family and Class_(biology), class. In biological classification, the order is a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes. An immediately higher rank, superorder, is sometimes added directly above order, with suborder directly beneath order. An order can also be defined as a group of related families. What does and does not belong to each order is determined by a taxonomist, as is whether a particular order should be recognized at all. Often there is no exact agreement, with different taxonomists each taking a different position. There are no hard rules that a taxonomist needs to follow in describing or recognizing an order. Some taxa are accepted almost universally, while others are recognized only rarely. The name of an order is usually written with a capital letter. Fo ...
