Short-tailed Pipefish
The short-tailed pipefish (''Microphis brachyurus'') is a species of fish in the family Syngnathidae. It is found in fresh and brackish waters from Sri Lanka and India east to southern Japan and the Society Islands. It inhabits places with little or no current in rivers, streams and estuaries. It formerly included three subspecies, but these are now regarded as separate species: ''Microphis aculeatus'' of the East Atlantic region, '' Microphis lineatus'' of the West Atlantic and Caribbean regions, and '' Microphis millepunctatus'' of the Western Indian Ocean region. The short-tailed pipefish reaches up to in standard length Fish measurement is the measuring of individual fish and various parts of their anatomies.

The IUCN Red List Of Threatened Species
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provide sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Standard Length
Fish measurement is the measuring of individual fish and various parts of their anatomies. These data are used in many areas of ichthyology, including taxonomy and fisheries biology. Overall length * Standard length (SL) is the length of a fish measured from the tip of the snout to the posterior end of the last vertebra or to the posterior end of the midlateral portion of the hypural plate. Simply put, this measurement excludes the length of the caudal (tail) fin. * Total length (TL) is the length of a fish measured from the tip of the snout to the tip of the longer lobe of the caudal fin, usually measured with the lobes compressed along the midline. It is a straight-line measure, not measured over the curve of the body. Standard length measurements are used with Teleostei (most bony fish), while total length measurements are used with Myxini (hagfish), Petromyzontiformes (lampreys), and (usually) Elasmobranchii (sharks and rays), as well as some other fishes. Total length measu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microphis Millepunctatus
''Microphis'' is a genus of pipefishes (stream pipefishes or river pipefishes) within the family Syngnathidae. Members of this genus are notable among the Syngnathidae for residing in mainly fresh and brackish waters. Adults breed in coastal rivers, streams, or lakes, and fertilized eggs are carried by the male pipefish in a brood pouch extending along his entire ventral surface. Species The currently recognized species in this genus are: * ''Microphis aculeatus'' ( Kaup, 1856) * ''Microphis argulus'' ( W. K. H. Peters, 1855) (flat-nosed pipepfish) * '' Microphis brachyurus'' (Bleeker, 1854) (short-tailed pipefish) * ''Microphis brevidorsalis'' ( de Beaufort, 1913) (stream pipefish) * '' Microphis caudocarinatus'' ( M. C. W. Weber, 1907) (slender pipefish, Tawarin river pipefish) * ''Microphis cruentus'' C. E. Dawson & Fourmanoir, 1981 (Dumbéa River pipefish) * ''Microphis cuncalus'' ( F.

Opossum Pipefish
''Microphis lineatus'', the opossum pipefish, is a species of fish in the family Syngnathidae. It is found in fresh, brackish and marine waters in the West Atlantic region, ranging from New Jersey, United States, to São Paulo, Brazil, including the Caribbean and Gulf of Mexico. It is often found in rivers, among water hyacinth roots, in mangrove and in ''Sargassum''. The opossum pipefish was formerly regarded as a subspecies of ''Microphis brachyurus'' (native to Asia and Oceania), but is now recognized as a full species by both FishBase and Catalog of Fishes. Furthermore, it is possible that full-freshwater populations currently included in the opossum pipefish represent a separate species. In the United States, the opossum pipefish is considered a species of concern by the National Marine Fisheries Service.U.S. National Marine Fisheries ServiceSpecies of Concern Due to uncertainty about its taxonomy and vulnerability to habitat destruction, it is considered data deficient by ...

Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Estuaries
An estuary is a partially enclosed coastal body of brackish water with one or more rivers or streams flowing into it, and with a free connection to the open sea. Estuaries form a transition zone between river environments and maritime environments and are an example of an ecotone. Estuaries are subject both to marine influences such as tides, waves, and the influx of saline water, and to fluvial influences such as flows of freshwater and sediment. The mixing of seawater and freshwater provides high levels of nutrients both in the water column and in sediment, making estuaries among the most productive natural habitats in the world. Most existing estuaries formed during the Holocene epoch with the flooding of river-eroded or glacially scoured valleys when the sea level began to rise about 10,000–12,000 years ago. Estuaries are typically classified according to their geomorphological features or to water-circulation patterns. They can have many different names, such as bays, har ...

Society Islands
The Society Islands (french: Îles de la Société, officially ''Archipel de la Société;'' ty, Tōtaiete mā) are an archipelago located in the South Pacific Ocean. Politically, they are part of French Polynesia, an overseas country of the French Republic. Geographically, they form part of Polynesia. The archipelago is believed to have been named by Captain James Cook during his first voyage in 1769, supposedly in honour of the Royal Society, the sponsor of the first British scientific survey of the islands; however, Cook wrote in his journal that he called the islands ''Society'' "as they lay contiguous to one another." History Dating colonization The first Polynesians are understood to have arrived on these islands around 1000AD. Oral history origin The islanders explain their origins in term of a orally transmitted story. The feathered god Ta'aroa lay in his shell. He called out but no-one answered, so he went back into his shell, where he stayed for aeons. When he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Achille Valenciennes
Achille Valenciennes (9 August 1794 – 13 April 1865) was a French zoologist. Valenciennes was born in Paris, and studied under Georges Cuvier. His study of parasitic worms in humans made an important contribution to the study of parasitology. He also carried out diverse systematic classifications, linking fossil and current species. He worked with Cuvier on the 22-volume "'' Histoire Naturelle des Poissons''" (Natural History of Fish) (1828–1848), carrying on alone after Cuvier died in 1832. In 1832, he succeeded Henri Marie Ducrotay de Blainville (1777–1850) as chair of ''Histoire naturelle des mollusques, des vers et des zoophytes'' at the Muséum national d'histoire naturelle. Early in his career, he was given the task of classifying animals described by Alexander von Humboldt (1769–1859) during his travels in the American tropics (1799 to 1803), and a lasting friendship was established between the two men. He is the binomial authority for many species of fish, such a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
