Hypostomus Borellii
''Hypostomus borellii'' is a species of catfish in the family Loricariidae. It is native to the upper and middle Pilcomayo River basin in Argentina, Uruguay, and Bolivia. The species reaches standard length and is believed to be a facultative air-breather. Etymology The fish is named in honor of French-born Italian zoologist Alfredo Borelli (1858–1943) of the Università di Torino The University of Turin (Italian language, Italian: ''Università degli Studi di Torino'', UNITO) is a public university, public research university in the city of Turin, in the Piedmont (Italy), Piedmont region of Italy.

George Albert Boulenger
George Albert Boulenger (19 October 1858 – 23 November 1937) was a Belgian-British zoologist who described and gave scientific names to over 2,000 new animal species, chiefly fish, reptiles, and amphibians. Boulenger was also an active botanist during the last 30 years of his life, especially in the study of roses. Life Boulenger was born in Brussels, Belgium, the only son of Gustave Boulenger, a Belgian public notary, and Juliette Piérart, from Valenciennes. He graduated in 1876 from the Free University of Brussels (1834–1969), Free University of Brussels with a degree in natural sciences, and worked for a while at the Royal Belgian Institute of Natural Sciences, Brussels, as an assistant naturalist studying amphibians, reptiles, and fishes. He also made frequent visits during this time to the ''National Museum of Natural History (France), Muséum national d'Histoire naturelle'' in Paris and the Natural History Museum, London, British Museum in London.

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] |
Catfish
Catfish (or catfishes; order (biology), order Siluriformes or Nematognathi) are a diverse group of ray-finned fish. Catfish are common name, named for their prominent barbel (anatomy), barbels, which resemble a cat's whiskers, though not all catfish have prominent barbels or "whiskers", with some seemingly not having them. Siluriformes as a whole are Fish scale, scale-less, with neither the Armoured catfish, armour-plated nor the naked species having scales. This order of fish are Autapomorphy, defined by features of the skull and swimbladder. Catfish range in size and behavior from the three List of largest fish, largest species alive, the Mekong giant catfish from Southeast Asia, the wels catfish of Eurasia, and the piraíba of South America, to detritivorous and scavenging bottom feeders, down to tiny ectoparasitic species known as the Candiru (fish), candirus. In the Southern United States, catfish species may be known by a variety of slang names, such as "mud cat", " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Loricariidae
Loricariidae is the largest family (biology), family of catfish (order Siluriformes), with over 90 genus, genera and just over 680 species. Loricariids originate from freshwater habitats of Costa Rica, Panama, and tropical and subtropical South America. These fish are noted for the bony plates covering their bodies and their suckermouths. Several genera are sold as "Plecostomus, plecos", notably the suckermouth catfish, ''Hypostomus plecostomus'', and are popular as aquarium fish. Common names Members of the family Loricariidae are commonly referred to as loricariids, suckermouth catfishes, armoured catfish (other), armoured catfish, or suckermouth armoured catfish. The name "plecostomus", and its shortened forms "pleco" and "plec", are used for many Loricariidae, since ''Plecostomus plecostomus'' (now called ''Hypostomus plecostomus'') was one of the first loricariid species imported for the fish-keeping hobby. Some loricariids are not normally considered "plecostomus", ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pilcomayo River
Pilcomayo (in Hispanicized spelling) ( Quechua Pillkumayu or Pillku Mayu, ''pillku'' red, ''mayu'' river, "red river", Guarani Ysyry Araguay ) is a river in central South America. At long, it is the longest western tributary of the Paraguay River. Its drainage basin is in area, and its mean discharge is . Along its course, the Pilcomayo silts up and splits into two main branches, North and South. After some distance, these branches rejoin to form the Lower Pilcomayo. The Pilcomayo rises in the foothills of the Andes mountain range in the Oruro Department in Bolivia, east of Lake Poopó. The Jach'a Juqhu River is considered the origin of the Pilcomayo. Upstream the Jach'a Juqhu River successively receives the names Aguas Calientes and Kachi Mayu. From the confluence with the Chillawa ''(Chillahua)'', the river is called Pilcomayo.

Fish Measurement
Fish measurement is the measuring of individual fish and various parts of their anatomies, for data used in many areas of ichthyology, including taxonomy and fishery 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. 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 (shark Sharks are a group of elasmobranch cartilaginous fish characterized by ...

Alfredo Borelli
Alfredo Borelli (18 November 1858, in Marseilles – 6 May 1943, in Boves, Piedmont) was a French-born Italian zoologist, who worked mainly in Turin but who, early in his natural history career, conducted field work in South America. Borelli graduated in law from Aix University in 1888 and practised as a lawyer in Marseilles for a while before deciding to follow his interest in the natural sciences, going to his family's home country of Italy and graduating from the University of Turin in 1886. He worked in Munich and Berlin but most of his scientific career was spent at the institute of zoology of the University of Turin, from where he retired in 1930. He worked at the '' Museo Regionale di Scienze Naturali di Torino'' from 1900 to 1913. The gecko '' Homonota borellii'', the amphisbaenian '' Amphisbaena borelli'', the millipede ''Urostreptus borellii'' (Silvestri, 1895) and the cichlid '' Apistogramma borellii'' are among the taxa named in honor of Borelli. He carried out field ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Università Di Torino
The University of Turin (Italian language, Italian: ''Università degli Studi di Torino'', UNITO) is a public university, public research university in the city of Turin, in the Piedmont (Italy), Piedmont region of Italy. It is one of the List of oldest universities in continuous operation, oldest universities in Europe and continues to play an important role in research and training. History Overview The University of Turin was founded as a ''studium'' in 1404, under the initiative of Prince Louis of Piedmont, Ludovico di Savoia. From 1427 to 1436 the seat of the university was transferred to Chieri and Savigliano. It was closed in 1536 following the invasion of the Savoy lands by France, and reestablished by Duke Emmanuel Philibert, Duke of Savoy, Emmanuel Philibert thirty years later. It started to gain its modern shape following the model of the University of Bologna, although significant development did not occur until the reforms made by Victor Amadeus II of Sardinia, ...
