Polychaete
Polychaeta () is a paraphyletic class (biology), class of generally marine invertebrate, marine annelid worms, common name, commonly called bristle worms or polychaetes (). Each body segment has a pair of fleshy protrusions called parapodia that bear many bristles, called chaetae, which are made of chitin. More than 10,000 species are described in this class. Common representatives include the lugworm (''Arenicola marina'') and the Alitta virens, sandworm or Alitta succinea, clam worm ''Alitta''. Polychaetes as a class are robust and widespread, with species that live in the coldest ocean temperatures of the abyssal plain, to forms which tolerate the extremely high temperatures near hydrothermal vents. Polychaetes occur throughout the Earth's oceans at all depths, from forms that live as plankton near the surface, to a 2- to 3-cm specimen (still unclassified) observed by the robot ocean probe Nereus (underwater vehicle), ''Nereus'' at the bottom of the Challenger Deep, the deepes ...

Jean Louis Armand De Quatrefages De Bréau
Jean Louis Armand de Quatrefages de Bréau (10 February 1810 – 12 January 1892) was a French biologist. Life He was born at Berthézène, in the commune of Valleraugue (Gard), the son of a Protestant farmer. He studied science and then medicine at the University of Strasbourg, where he took the double degree of M.D. and D.Sc., one of his theses being a ''Théorie d'un coup de canon'' (November 1829); next year he published a book, ''Sur les arolithes'', and in 1832 a treatise on ''L'Extraversion de la vessie''. Moving to Toulouse, he practised medicine for a short time, and contributed various memoirs to the local ''Journal de Médecine'' and to the ''Annales des sciences naturelles'' (1834—36). But being unable to continue his research in the provinces, he resigned the chair of zoology to which he had been appointed, and in 1839 settled in Paris, where he found in Henri Milne-Edwards a patron and a friend. Elected professor of natural history at the Lycée Napoléon in 185 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edward Forbes
Edward Forbes FRS, FGS (12 February 1815 – 18 November 1854) was a Manx naturalist. In 1846, he proposed that the distributions of montane plants and animals had been compressed downslope, and some oceanic islands connected to the mainland, during the recent ice age. This mechanism, which was the first natural explanation to explain the distributions of the same species on now-isolated islands and mountain tops, was discovered independently by Charles Darwin, who credited Forbes with the idea. He also incorrectly deduced the so-called azoic hypothesis, that life under the sea would decline to the point that no life forms could exist below a certain depth. Early years Forbes was born at Douglas on the Isle of Man. His father was a well-to-do banker. As a child, Forbes was very interested in collecting insects, shells, minerals, fossils, and plants. Due to poor health, he was unable to attend school from his 5th through his 11th years. In 1828, he started attending the Ath ...

Charles Carmichael Arthur Monro
Charles is a masculine given name predominantly found in English and French speaking countries. It is from the French form ''Charles'' of the Proto-Germanic name (in runic alphabet) or ''*karilaz'' (in Latin alphabet), whose meaning was "free man". The Old English descendant of this word was '' Ċearl'' or ''Ċeorl'', as the name of King Cearl of Mercia, that disappeared after the Norman conquest of England. The name was notably borne by Charlemagne (Charles the Great), and was at the time Latinized as ''Karolus'' (as in ''Vita Karoli Magni''), later also as '' Carolus''. Some Germanic languages, for example Dutch and German, have retained the word in two separate senses. In the particular case of Dutch, ''Karel'' refers to the given name, whereas the noun ''kerel'' means "a bloke, fellow, man". Etymology The name's etymology is a Common Germanic noun ''*karilaz'' meaning "free man", which survives in English as churl (< Old English ''ċeorl''), which developed its depr ...
