Scaphiodonichthys Acanthopterus
''Scaphiodonichthys acanthopterus'' is a freshwater fish of the family Cyprinidae (carps and minnows). It is found in clear, fast-moving streams and tributaries of the Mekong, Nam Xam, Da and Chao Phraya river basins in Indochina. ''S. acanthopterus'' is most commonly found in waterways with a rocky bottom and under complete tree cover. Taxonomy The original description of this fish is attributed to Fowler in 1934, although he originally assigned the name ''Scaphiodontopsis acanthopterus''. The genus name of ''Scaphiodonichtys'' is from the Greek (boat), (teeth), (fish). Disttibution, habitat & ecology ''S. acanthopterus'' is found in the South-East Asian countries of Cambodia, Laos, Thailand, and Vietnam as well in Yunnan, China. It inhabits several river basins, including the Mekong, Chao Phraya, Nam Theun, and Xe Bangfai, mostly living in smaller tributaries and streams with clear, fast moving water, and a rocky bottom. This fish has been documented between 300 and 2500 ... [...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 ...

Mekong
The Mekong or Mekong River ( , ) is a transboundary river in East Asia and Southeast Asia. It is the world's twelfth-longest river and the third-longest in Asia with an estimated length of and a drainage area of , discharging of water annually. From its headwaters in the Tibetan Plateau, the river runs through Southwest China (where it is officially called the Lancang River), Myanmar, Laos, Thailand, Cambodia, and southern Vietnam. The extreme seasonal variations in flow and the presence of rapids and waterfalls in the Mekong make navigation difficult, though the river remains a major trade route between Tibet and Southeast Asia. The construction of hydroelectric dams along the Mekong in the 2000s through the 2020s has caused serious problems for the river's ecosystem, including the exacerbation of drought. Names The Mekong was originally called ''Mae Nam Khong'' from a contracted form of Kra-Dai shortened to ''Mae Khong''. In Thai and Lao, ''Mae Nam'' ("Mother ...

Fish Described In 1934
A fish (: fish or fishes) is an aquatic, anamniotic, gill-bearing vertebrate animal with swimming fins and a hard skull, but lacking limbs with digits. Fish can be grouped into the more basal jawless fish and the more common jawed fish, the latter including all living cartilaginous and bony fish, as well as the extinct placoderms and acanthodians. In a break to the long tradition of grouping all fish into a single class (Pisces), modern phylogenetics views fish as a paraphyletic group. Most fish are cold-blooded, their body temperature varying with the surrounding water, though some large active swimmers like white shark and tuna can hold a higher core temperature. Many fish can communicate acoustically with each other, such as during courtship displays. The study of fish is known as ichthyology. The earliest fish appeared during the Cambrian as small filter feeders; they continued to evolve through the Paleozoic, diversifying into many forms. The earliest fish wi ...
