Phallostethus Cuulong
''Phallostethus cuulong'' is a species of fish in the family Phallostethidae. It was discovered in 2009 and described in 2012. This species is found at depths of in tidal canals on the Mekong Delta. This species attains about in standard length Fish measurement is the measuring of individual fish and various parts of fish anatomy, their anatomies, for data used in many areas of ichthyology, including Taxonomy (biology), taxonomy and fishery biology. Overall length Standard length (SL) is ... and is translucent white. Males have their gonads under the chin – along with a serrated saw and rod for grasping females. The name ''cuulong'' is from the Vietnamese name of the river system where they are found, '' Cửu Long River''.

Phallostethidae
Phallostethidae, also known as priapium fish, is a family of atheriniform fish native to freshwater and brackish habitats in southeast Asia. They are small, no more than in length, with partially translucent bodies. They are found in fresh and brackish water from Thailand to the Philippines and Sulawesi. They are named for a muscular organ found under the chin of males. This organ, which may possess small testicles, is used together with the pelvic fins to grasp the female during mating. Unlike most other fish, priapium fishes exhibit internal fertilisation, although they are oviparous. Subdivision The family Phallostethidae is divided into two subfamilies and four genera: * Subfamily Phallostethinae Regan, 1916 ** Genus ''Neostethus'' Regan, 1916 ** Genus ''Phallostethus'' Regan, 1916 ** Genus ''Phenacostethus'' Myers, 1928 * Subfamily Gulaphallinae Aurich, 1937 ** Genus ''Gulaphallus ''Gulaphallus'' is a genus of fishes in the family Phallostethidae, native to the Philip ...

Phallostethinae
Phallostethinae is a subfamily of fishes, one of two subfamilies in the family Phallostethidae, the priapiumfishes. The species in this subfamily are characterised mainly by having highly protrusible jaws. The genus ''Neostethus'' appears to be the sister taxon to the other two genera in the subfamily. The species in the Phallostethinae are found in south-east Asia, the Malay Archipelago and the Philippines. Genera The following three genera are classified in the subfamily Phallostethinae: * ''Neostethus'' Regan, 1916 * ''Phallostethus'' Regan, 1913 * ''Phenacostethus ''Phenacostethus'' is a genus of fishes in the family Phallostethidae found in freshwater and brackish habitats in southeast Asia Southeast Asia is the geographical United Nations geoscheme for Asia#South-eastern Asia, southeastern region ...''

Charles Tate Regan
Charles Tate Regan (1 February 1878 – 12 January 1943) was a British ichthyology, ichthyologist, working mainly around the beginning of the 20th century. He did extensive work on fish classification schemes. Born in Sherborne, Dorset, he was educated at Derby School and Queens' College, Cambridge and in 1901 joined the staff of the Natural History Museum, London, Natural History Museum, where he became Keeper of Zoology, and later director of the entire museum, in which role he served from 1927 to 1938. Regan was elected Fellow of the Royal Society in 1917. Regan mentored a number of scientists, among them Ethelwynn Trewavas, who continued his work at the British Natural History Museum. Taxon described by him *See :Taxa named by Charles Tate Regan Among the species he described is the Siamese fighting fish (''Betta splendens''). In turn, a number of fish species have been named ''regani'' in his honour: Taxon named in his honor *A Thorny Catfish ''Anadoras regani'' (Stein ...

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Brackish
Brackish water, sometimes termed brack water, is water occurring in a natural environment that has more salinity than freshwater, but not as much as seawater. It may result from mixing seawater (salt water) and fresh water together, as in estuaries, or it may occur in brackish fossil aquifers. The word comes from the Middle Dutch root '' brak''. Certain human activities can produce brackish water, in particular civil engineering projects such as dikes and the flooding of coastal marshland to produce brackish water pools for freshwater prawn farming. Brackish water is also the primary waste product of the salinity gradient power process. Because brackish water is hostile to the growth of most terrestrial plant species, without appropriate management it can be damaging to the environment (see article on shrimp farms). Technically, brackish water contains between 0.5 and 30 grams of salt per litre—more often expressed as 0.5 to 30 parts per thousand (‰), which is a spec ...

Southeast Asia
Southeast Asia is the geographical United Nations geoscheme for Asia#South-eastern Asia, southeastern region of Asia, consisting of the regions that are situated south of China, east of the Indian subcontinent, and northwest of the Mainland Australia, Australian mainland, which is part of Oceania. Southeast Asia is bordered to the north by East Asia, to the west by South Asia and the Bay of Bengal, to the east by Oceania and the Pacific Ocean, and to the south by Australia (continent), Australia and the Indian Ocean. Apart from the British Indian Ocean Territory and two out of Atolls of the Maldives, 26 atolls of the Maldives in South Asia, Maritime Southeast Asia is the only other subregion of Asia that lies partly within the Southern Hemisphere. Mainland Southeast Asia is entirely in the Northern Hemisphere. Timor-Leste and the southern portion of Indonesia are the parts of Southeast Asia that lie south of the equator. The region lies near the intersection of Plate tectonics, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
