Narcine Atzi
''Narcine'' is a genus of electric rays in the family Narcinidae. These species have a rounded pectoral fin disc and two dorsal fins, the first usually smaller than the second and placed behind the pelvic fin bases. The tail is longer than the disc and has a lateral fold. The spiracles are close behind the eyes, the nasal flaps are merged into a flap in front of the mouth. The teeth are nearly flat, with a central point. Species There are currently 21 recognized species in this genus: * '' Narcine atzi'' M. R. de Carvalho & J. E.

Eocene
The Eocene ( ) Epoch is a geological epoch (geology), epoch that lasted from about 56 to 33.9 million years ago (mya). It is the second epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), Era. The name ''Eocene'' comes from the Ancient Greek (''ēṓs'', "dawn") and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch. The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isotope Carbon-13, 13C in the atmosphere was exceptionally low in comparison with the more common isotope Carbon-12, 12C. The end is set at a major extinction event called the ''Grande Coupure'' (the "Great Break" in continuity) or the Eocene–Oligocene extinction event, which may be related to the impact of one or more large bolides in Popigai impact structure, Siberia and in what is now ...

David Starr Jordan
David Starr Jordan (January 19, 1851 – September 19, 1931) was the founding president of Stanford University, serving from 1891 to 1913. He was an ichthyologist during his research career. Prior to serving as president of Stanford University, he had served as president of Indiana University from 1884 to 1891. Starr was also a strong supporter of eugenics, and his published views expressed a fear of "race-degeneration" and asserted that cattle and human beings are "governed by the same laws of selection". He was an antimilitarist since he believed that war killed off the best members of the gene pool, and he initially opposed American involvement in World War I. Early life and career Jordan was born in Gainesville, New York, and grew up on a farm in upstate New York. His parents made the unorthodox decision to educate him at a local girls' high school. His middle name, Starr, does not appear in early census records, and was apparently self-selected; he had begun using ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Narcine Entemedor
''Narcine entemedor'', the giant electric ray or Cortez electric ray, is a species of numbfish, family Narcinidae, native to the eastern Pacific Ocean from the Gulf of California to Panama. It is found in shallow water on sandy bottoms and sometimes adjacent to reefs. This species is closely related to the lesser electric ray (''Narcine bancroftii'') from the western Atlantic, and may represent the same species. The specific epithet ''entemedor'' seems to be the Spanish equivalent of "intimidator". This species attains a maximum length of 76 cm (30 in). The flattened pectoral fin disk is round, as long as it is wide, and overlapping the origin of the large pelvic fins. The eyes are much smaller than the spiracles, which are edged with small tubercles. The nostril on each side is not divided into two separate apertures. The teeth are mostly exposed when the mouth is closed. The tail is equal in length to the disk, with loose lateral folds of skin and two dorsal fins of eq ...

Nelson Annandale
Thomas Nelson Annandale CIE FRSE (15 June 1876, in Edinburgh – 10 April 1924, in Calcutta) was a British zoologist, entomologist, anthropologist, and herpetologist. He was the founding director of the Zoological Survey of India. Life The eldest son of Thomas Annandale, the regius professor of clinical surgery at the University of Edinburgh. His maternal grandfather was a publisher, William Nelson. Thomas was educated at Rugby School, Balliol College, Oxford where he studied under Ray Lankester and E. B. Tylor (doing better in anthropology than zoology), and at the University of Edinburgh where he studied anthropology, receiving a D.Sc. (1905). As a student he made visits to Iceland and the Faeroe Islands. In 1899 he travelled with Herbert C. Robinson as part of the Skeat Expedition to the northern part of the Malay Peninsula. Annandale went to India in 1904 as Deputy Superintendent under A.W. Alcock of the Natural History Section of the Indian Museum. He was a deputy dir ...

Narcine Brevilabiata
The shortlip electric ray (''Narcine brevilabiata''), is a species of electric ray in the numbfish family, Narcinidae. It may be synonymous with the blackspotted numbfish, ''Narcine maculata''. The shortlip electric ray is found in shallow continental shelf waters offshore of China, Malaysia, Thailand, and Vietnam, at a depth of 41 to 70 meters. It is assessed as Vulnerable on the IUCN Red List, as it is caught as by-catch in large numbers by shrimp trawling fisheries operating throughout its range. The shortlip electric ray has a rounded pectoral fin disc, with a tail not longer than the disc. Unlike most species of ''Narcine'', the second dorsal fin of ''N. brevilabiata'' is smaller than the first. The forward part of the pelvic fins are expanded into long lobes, while their rear margins are concave. The tooth bands are exposed and subtriangular in shape, with the upper clearly wider than the lower. It has small, dark spots and blotches above, with a few much larger circular sp ...

Ignaz Von Olfers
Ignaz Franz Werner Maria von Olfers (30 August 1793 – 23 April 1871) was a German naturalist, historian and diplomat. Olfers was born in Münster. In 1816 he travelled to Brazil as a diplomat. In 1839 he was made director of the royal art collections and had significant influence on Frederick William IV of Prussia for a re-development of the Museumsinsel, Berlin. Together with architect Friedrich August Stueler, he developed the concept of the Neues Museum, Berlin and had great influence on organisation and presentation of exhibits and interior. His daughter was the writer and illustrator Marie von Olfers. Olfers described a number of new mammal species in Wilhelm Ludwig von Eschwege's ''Journal von Brasilien'' (1818). In 1819, '' Olfersia'' which is a genus of ferns (in the family Dryopteridaceae) from South America, was published, then a species of South American snake Snakes are elongated, Limbless vertebrate, limbless, carnivore, carnivorous reptiles of the suborde ...

It inhabits coastal waters of the Southwest Atlantic from souther Brazil through Uruguay to northern Argentina. Habitat This species is considered a “warm water species”. When there's a temperature gradient between an inshore and an offshore they will habituate at the depths with the highest temperature (Menni 2000). The density of this species had a higher concentration in temperatures that were greater than 20ºC (Vianna 2009). They prefer shallow waters because that is usually the warmest part of the water. During the summer, they are abundant in coastal water with depths that go to 20 meters and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Hamilton Smith
Lieutenant-Colonel Charles Hamilton Smith, KH, KW, FRS, FLS, (26 December 1776 in East Flanders, in the United Provinces of the Netherlands – 21 September 1859 in Plymouth) was an English artist, naturalist, antiquary, illustrator, soldier, and spy. Military service His military career began in 1787, when he studied at the Austrian academy for artillery and engineers at Mechelen and Leuven in Belgium. Although his military service, which ended in 1820 and included the Napoleonic Wars, had him travel extensively (including the West Indies, Canada, and United States), much of his time was spent at a desk job in Britain. One of his noteworthy achievements was an 1800 experiment to determine which colour should be used for military uniforms. The increasing accuracy of firearms, especially rifles, brought advantages to shades which offer a less distinctive target – by testing the accuracy of a rifle company against grey, green, and red targets, he showed scientifically the a ...
