Schistura Sexcauda
''Schistura sexcauda'' is a species of ray-finned fish, a stone loach, in the genus ''Schistura''. It is found in the basin of the Chao Phraya River in central Thailand where it has been recorded in streams with a moderate to fast current and in riffles, over substrates consisting of gravel to stone. It is known to be raised in local subsistence fisheries and traded both nationally and internationally as an ornamental fish. Some authorities regard '' Schistura fowleriana'' as a synonym A synonym is a word, morpheme, or phrase that means precisely or nearly the same as another word, morpheme, or phrase in a given language. For example, in the English language, the words ''begin'', ''start'', ''commence'', and ''initiate'' are a ... of this species. Etymology The genus name Schistura refers to the fish's forked caudal fins, coming from the Greek ''schizein'' and ''oura'' meaning respectively "to divide" and "tail". The species name sexcauda comes from Latin ''sex'' and ''cauda ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henry Weed Fowler
Henry Weed Fowler (March 23, 1878 – June 21, 1965) was an American zoologist born in Holmesburg, Philadelphia, Holmesburg, Pennsylvania. He studied at Stanford University under David Starr Jordan. He joined the Academy of Natural Sciences in Philadelphia and worked as an assistant from 1903 to 1922, associate curator of vertebrates from 1922 to 1934, curator of fish and reptiles from 1934 to 1940 and curator of fish from 1940 to 1965. He published material on numerous topics including crustaceans, birds, reptiles and amphibians, but his most important work was on fish. In 1927 he co-founded the American Society of Ichthyologists and Herpetologists and acted as treasurer until the end of 1927. In 1934, he went to Cuba, alongside Charles Cadwalader (president of the Academy of Natural Sciences of Drexel University, Academy of Natural Sciences of Philadelphia), at the invitation of Ernest Hemingway to study billfishes, he stayed with Hemingway for six weeks and the three men devel ...

Hugh McCormick Smith
Hugh McCormick Smith, also H. M. Smith (November 21, 1865 – September 28, 1941) was an American ichthyologist and administrator in the United States Bureau of Fisheries. Biography Smith was born in Washington, D.C. In 1888, he received a Doctor of Medicine from Georgetown University; then, in 1908, a Doctor of Law from the Dickinson School of Law at Dickinson College. He began working for the United States Fish Commission (formally, the United States Commission on Fish and Fisheries) in 1886 as an assistant. He directed the scientific research center there from 1897 to 1903. From 1901 to 1902, he directed the Marine Biological Laboratory at Woods Hole, Massachusetts. At the same time, he was on the faculty at Georgetown, teaching medicine from 1888 to 1902 and histology from 1895 to 1902. From 1907 to 1910, Smith led the scientific party aboard the U.S. Bureau of Fisheries (successor organization of the U.S. Fish Commission) research ship during her two-and-a-half-year exp ...

Ray-finned Fish
Actinopterygii (; ), members of which are known as ray-finned fish or actinopterygians, is a class of bony fish that comprise over 50% of living vertebrate species. They are so called because of their lightly built fins made of webbings of skin supported by radially extended thin bony spines called '' lepidotrichia'', as opposed to the bulkier, fleshy lobed fins of the sister clade Sarcopterygii (lobe-finned fish). Resembling folding fans, the actinopterygian fins can easily change shape and wetted area, providing superior thrust-to-weight ratios per movement compared to sarcopterygian and chondrichthyian fins. The fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the articulation between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). The vast majority of actinopterygians are teleosts. By species count, they dominate the subphylum Vertebrata, and constitute nearly 99% of the over 30,000 extant ...

Chao Phraya River
The Chao Phraya River is the major river in Thailand, with its low alluvial plain forming the centre of the country. It flows through Bangkok and then into the Gulf of Thailand. Etymology Written evidence of the river being referred to by the name ''Chao Phraya'' dates only to the reign of King Mongkut (Rama IV, 1850–1868). It is unknown what name, if any at all, was used for the river in older times. The river was likely known simply by the Thai word for 'river', (), and foreign documents and maps, especially by Europeans visiting during the Ayutthaya period, usually named the river the ''Menam''. The name Chao Phraya likely comes from (), an alternative name, documented from around 1660 in the reign of King Narai, of the settlement that is now Samut Prakan. Historian Praphat Chuvichean suggests that the name, which is a Thai noble titles, title of nobility, originated from the story of two Khmer idols being unearthed in 1498 at the settlement that was by the mouth of the ...

Riffle
A riffle is a shallow landform in a flowing channel. Colloquially, it is a shallow place in a river where water flows quickly past rocks. However, in geology a riffle has specific characteristics. Topographic, sedimentary and hydraulic indicators Riffles are almost always found to have a very low discharge compared to the flow that fills the channel (approximately 10–20%), and as a result the water moving over a riffle appears shallow and fast, with a wavy, disturbed water surface. The water's surface over a riffle at low flow also has a much steeper slope than that over other in-channel landforms. Channel sections with a mean water surface slope of roughly 0.1 to 0.5% exhibit riffles, though they can occur in steeper or gentler sloping channels with coarser or finer bed materials, respectively. Except in the period after a flood (when fresh material is deposited on a riffle), the sediment on the riverbed in a riffle is usually much coarser than on that in any other in-chan ...

Synonym (taxonomy)
In taxonomy, the scientific classification of living organisms, a synonym is an alternative scientific name for the accepted scientific name of a taxon. The Botanical nomenclature, botanical and Zoological nomenclature, zoological codes of nomenclature treat the concept of synonymy differently. * In nomenclature, botanical nomenclature, a synonym is a Binomial nomenclature, scientific name that applies to a taxon that now goes by a different scientific name. For example, Carl Linnaeus, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different Binomial nomenclature, binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
