Brachyhypopomus

Hypopomidae
The Hypopomidae are a family of fishes in the order Gymnotiformes known as the bluntnose knifefish. They may also be called grass or leaf knifefishes. These electric fish are not often eaten, of little commercial importance, rarely kept as aquarium fish, and poorly studied; however, species in this family may constitute a significant fraction of the biomass in the areas they inhabit. These fish originate from fresh water in Panama and South America. The Hypopomidae are confined to the humid neotropics, ranging the Río de la Plata of Argentina (35°S) to the Río Tuira of Panama (8°N). Hypopomids are known from the continental waters of all South American countries except Chile, and are most diverse in the Amazon Basin. Description Teeth are absent on the oral jaws. Unlike the closely related Rhamphichthyidae, species of this family do not have a tubular snout, but a blunt, short one. Also, the nostrils are well separated. This family contains the smallest gymnotiforms, ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microsternarchus
''Microsternarchus'' is a genus of bluntnose knifefish that is found in creeks and streams, often in areas with submerged vegetation, roots and leaf litter, in the Amazon, Orinoco, Essequibo–Rupununi and Río de la Plata basins in South America.Cox Fernandes, C., Nogueira, A., Williston, A. & Alves-Gomes, J.A. (2015): A new species of electric knifefish from the rio Negro, Amazon basin (Gymnotiformes: Hypopomidae, Microsternarchini). ''Proceedings of the Academy of Natural Sciences of Philadelphia, 164 (1): 213-227.'' The two recognized species are both small knifefish, with the largest being ''M. bilineatus'' at up to in total length. The other is ''M. brevis'', which at up to only is the world's smallest knifefish.

Camouflage
Camouflage is the use of any combination of materials, coloration, or illumination for concealment, either by making animals or objects hard to see, or by disguising them as something else. Examples include the leopard's spotted coat, the battledress of a modern soldier, and the leaf-mimic katydid's wings. A third approach, motion dazzle, confuses the observer with a conspicuous pattern, making the object visible but momentarily harder to locate, as well as making general aiming easier. The majority of camouflage methods aim for crypsis, often through a general resemblance to the background, high contrast disruptive coloration, eliminating shadow, and countershading. In the open ocean, where there is no background, the principal methods of camouflage are transparency, silvering, and countershading, while the ability to produce light is among other things used for counter-illumination on the undersides of cephalopods such as squid. Some animals, such as chameleons and o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leonard Peter Schultz
Leonard Peter Schultz (1901–1986) was an American ichthyologist. Biography Schultz was born in 1901, at Albion, Michigan. He received education on ichthyology at Albion College, in which he got his bachelor's degree, in 1924. In 1926, he got his master's degree from the University of Michigan, and then in 1932 from the University of Washington. From 1928 till 1936, he taught at the College of Fisheries at University of Washington. He was appointed as an assistant curator at the Division of Fishes of the United States National Museum. During the same year he joined Smithsonian Institution, where he remained till retirement in 1968. In 1938 he became a curator of the Division. While in retirement, he continued to work as a Research Associate of the Division of Fishes. He was one of the scientists that was sent to work for the U.S. Navy, on Operation Crossroads, that was conducted at the Bikini Atoll in 1946. Aside from testing an atomic bomb during the operation, he also col ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
