Wilhelm Moritz Keferstein
Wilhelm Moritz Keferstein (7 June 1833, Winsen (Luhe) – 25 January 1870) was a German naturalist. He described a number of reptiles and amphibians for the first time. He originally studied hydraulic engineering in Hanover, later becoming a lecturer and professor of zoology at the University of Göttingen. With zoologist Ernst Ehlers (1835-1925), he wrote ''Zoologische Beiträge gesammelt im Winter 1859/60 in Neapel und Messina...'' in 1861. With Karl Wilhelm von Kupffer (1829-1902) he was co-author of a study on the electric organs of '' Gymnotus'' and ''Mormyrus'' that was published in Henle and Pfeufer's ''Zeitschrift für rationelle Medicin'' (Journal of rational medicine). He also made important contributions to Heinrich Georg Bronn's ''Die Klassen und Ordnungen des Thier-Reichs'' (Classes and Orders of the Animal Kingdom). Keferstein's tree frog is named after him (a species he described in 1868), as is a genus of polychaetes, ''Kefersteinia'' (family Hesionidae ...

Charles Alexandre Lesueur
Charles Alexandre Lesueur (1 January 1778 in Le Havre – 12 December 1846 in Le Havre) was a French naturalist, artist, and explorer. He was a prolific natural-history collector, gathering many type specimens in Australia, Southeast Asia, and North America, and was also responsible for describing numerous species, including the spiny softshell turtle ('' Apalone spinifera''), smooth softshell turtle ('' A. mutica''), and common map turtle ('' Graptemys geographica''). Both Mount Lesueur and Lesueur National Park in Western Australia are named in his honor. Early life Charles Alexandre Lesueur was born on January 1, 1778, to Jean-Baptiste Denis Lesueur and Charlotte Thieullent. Charlotte died when Charles was sixteen years old, and Charles' maternal grandmother took care of him and his siblings.

François Péron
François Auguste Péron (22 August 1775 – 14 December 1810) was a French naturalist and explorer. Life Péron was born in Cérilly, Allier, in 1775, the son of a tailor (not a harness maker as is frequently asserted). Although intended for the priesthood, due to the Revolution, Péron reluctantly joined the 2nd Allier Volunteer Battalion in 1792 and helped defend besieged Landau. In the following year he was wounded and taken prisoner by Prussian forces near Hochspeyer in the Pfalzwald. Imprisoned in the fortress of Magdeburg he was not repatriated to France until 1794. Having lost the sight of an eye, Péron was invalided out of the army. For two years he was Town Clerk in Cérilly before gaining a scholarship to study medicine in Paris. While in Paris, Péron changed interests towards zoology, spending time at the Muséum d'histoire naturelle. In 1800, after an unhappy love affair, he sought to join Nicolas Baudin's expedition to Australian waters as an anthropological o ...

Turritopsis Nutricula
''Turritopsis nutricula'' is a small hydrozoan that once reaching adulthood, can transfer its cells back to childhood. This adaptive trait likely evolved in order to extend the life of the individual. Several different species of the genus ''Turritopsis'' were formerly classified as ''T. nutricula'', including the "immortal jellyfish" which is now classified as '' T. dohrnii''. Life cycle Hydrozoans have two distinct stages in their life, a polyp stage and a medusa stage. The polyp stage is benthic, with the cells forming colonies, while the medusa stage is a singular, planktonic organism. Generally in hydrozoa the medusa develops from the asexual budding of the polyp and the polyp results from sexual reproduction of medusae. In ''T. nutricula'', planktonic medusa have the capability to bud polyps or medusae which also have the ability to spawn new medusae. Several nominal species have been described for this genus, but most of them had been synonymized and attributed to on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Cleveland Nutting
Charles Cleveland Nutting (May 25, 1858 – January 23, 1927 in Iowa City, Iowa) was an American zoologist, born in Jacksonville, Illinois. He graduated from Blackburn University (1880) and received the M. A. degree from the same institution in 1882. He conducted various zoological expeditions—in Central America for the Smithsonian Institution (1882–84), in Florida (1885), on the Saskatchewan River (1891)—and was naturalist of the ''Albatross'' Hawaiian expedition in 1902. He was professor of zoology and curator of the Museum of Natural History of the University of Iowa from 1886 to 1890 and thereafter was head of his department.
