Glaphyropoma
''Glaphyropoma'' is a genus of small pencil catfishes native to Bahia in Brazil. Species There are currently two recognized species in this genus: * '' Glaphyropoma rodriguesi'' de Pinna, 1992 * '' Glaphyropoma spinosum'' Bichuette, de Pinna & Trajano, 2008 The single synapomorphy proposed for ''Glaphyropoma'' is the marked narrowing of the first hypobranchial, giving the hypobranchial a slender shape. ''G. rodriguesi'' grows to about 5.1 centimetres (2.0 in) in standard length and originates from the Mucujê River, a tributary of Paraguaçu River in Brazil. ''G. spinosum'' is known to grow as large as 5.8 cm (2.3 in) in standard length. It is known from subterranean waters in the Diamantina Plateau of the Bahia State in central northeastern Brazil. This is the first-known troglomorphic species in the subfamily Copionodontinae. These fish live in quartzitic caves formed by erosion Erosion is the action of surface processes (such as water flow or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Copionodontinae
The Copionodontinae are a subfamily of catfishes (order Siluriformes) of the family Trichomycteridae. It includes two genera, '' Copionodon'' and ''Glaphyropoma''. Classification Copionodontines are remarkably primitive in body form, and lack many of the synapomorphies previously used to diagnose the family Trichomycteridae. Little doubt exists that the Copionodontinae form a monophyletic group, diagnosed by several unambiguous synapomorphies, including a unique dentition composed of spatulate teeth not seen anywhere else in the Trichomycteridae. A few characters also support the genera ''Copionodon'' and ''Glaphyropoma'' as monophyletic subunits. Distribution and ecology Copionodontines occur exclusively in the Chapada Diamantina; though the plateau is drained by four river basins, so far, these fish are exclusively found in drainages associated with the Paraguaçu River The Paraguaçu River () is a river in Bahia state of eastern Brazil. It runs from the Chapada Diamantina ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pencil Catfish
Trichomycteridae is a family of catfishes commonly known as pencil catfishes or parasitic catfishes. This family includes the candiru fish (''Vandellia cirrhosa''), feared by some people for its alleged habit of entering into the urethra of humans. They are one of the few parasitic chordates. Another species is the life monsefuano (''Trichomycterus punctulatus'') which was important to the Moche culture and still an important part of Peruvian cuisine.FondazioneslowfoodLife monsefuano.Retrieved 28 April 2017. This family is prohibited from being imported into various parts of the United States. Taxonomy The Trichomycteridae comprise about 42 genera and 286 species described. It is the second-most diverse family of the superfamily Loricarioidea. Numerous species still remain undescribed. The monophyly of Trichomycteridae is well-supported. The family is divided into eight subfamilies. The only subfamily that is not monophyletic is the largest one, Trichomycterinae. A large cla ...

Glaphyropoma Rodriguesi
''Glaphyropoma rodriguesi'' is a species of pencil catfish endemic to Brazil. This species grows to a length of SL. Etymology The catfish is named in honor of herpetologist Miguel Trefaut Rodrigues (b. 1953), of the Universidade de São Paulo The Universiade is an international multi-sport event, organized for university athletes by the International University Sports Federation (FISU). The name is a portmanteau of the words "University" and "Olympiad". The Universiade is referred t ..., who, along with his students, collected and discovered the first-known specimens of this subfamily from a high-altitude region of north-eastern central Brazil.

Cavefish
Cavefish or cave fish is a generic term for fresh and brackish water fish adapted to life in caves and other underground habitats. Related terms are subterranean fish, troglomorphic fish, troglobitic fish, stygobitic fish, phreatic fish and hypogean fish.Romero, Aldemaro, editor (2001). ''The Biology of Hypogean Fishes.'' Developments in Environmental Biology of Fishes. Helfman, G.S. (2007). ''Fish Conservation: A Guide to Understanding and Restoring Global Aquatic Biodiversity and Fishery Resources'', pp. 41–42. Island Press. There are more than 200 scientifically described species of obligate cavefish found on all continents, except Antarctica. Although widespread as a group, many cavefish species have very small ranges and are seriously threatened.Fenolio, D.B.; Zhao, Y.; Niemiller, M.L.; and Stout, J. (2013).

Chapada Diamantina
Chapada Diamantina (; Portuguese for the "Diamond Plateau") is a region of Bahia state, in the Northeast of Brazil. This mountain range is known as “Serra do Espinhaço,” in Minas Gerais state, south of Bahia. Description The Chapada Diamantina lies at the center of Bahia State and forms the northern part of the Espinhaço Mountain Range. It has approximately and encompasses 58 municipalities. Technically this region is considered a part of the caatinga biome, and contains some of its highest elevations, most of it above . The vegetation; a product of the physiographic conditions, is known as cerrado, and consists of rocky plains, dry forests, and caatinga desert vegetation, all of which harbour a great deal of biodiversity and unique endemisms. The region is considered to have a Mesotermic climate, of the Cwb type, according to Köppen Climate classifications. It is normally quite cooler than its surrounding areas, with an average annual temperature under 22 °C. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish Of Brazil
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Most fis ...

Erosion
Erosion is the action of surface processes (such as water flow or wind) that removes soil, rock, or dissolved material from one location on the Earth's crust, and then transports it to another location where it is deposited. Erosion is distinct from weathering which involves no movement. Removal of rock or soil as clastic sediment is referred to as ''physical'' or ''mechanical'' erosion; this contrasts with ''chemical'' erosion, where soil or rock material is removed from an area by dissolution. Eroded sediment or solutes may be transported just a few millimetres, or for thousands of kilometres. Agents of erosion include rainfall; bedrock wear in rivers; coastal erosion by the sea and waves; glacial plucking, abrasion, and scour; areal flooding; wind abrasion; groundwater processes; and mass movement processes in steep landscapes like landslides and debris flows. The rates at which such processes act control how fast a surface is eroded. Typically, physical erosion procee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quartz
Quartz is a hard, crystalline mineral composed of silica (silicon dioxide). The atoms are linked in a continuous framework of SiO4 silicon-oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO2. Quartz is the second most abundant mineral in Earth's continental crust, behind feldspar. Quartz exists in two forms, the normal α-quartz and the high-temperature β-quartz, both of which are chiral. The transformation from α-quartz to β-quartz takes place abruptly at . Since the transformation is accompanied by a significant change in volume, it can easily induce microfracturing of ceramics or rocks passing through this temperature threshold. There are many different varieties of quartz, several of which are classified as gemstones. Since antiquity, varieties of quartz have been the most commonly used minerals in the making of jewelry and hardstone carvings, especially in Eurasia. Quartz is the mineral defining the val ...

Bahia State
Bahia ( , , ; meaning "bay") is one of the 26 states of Brazil, located in the Northeast Region of the country. It is the fourth-largest Brazilian state by population (after São Paulo, Minas Gerais, and Rio de Janeiro) and the 5th-largest by area. Bahia's capital is the city of Salvador (formerly known as "Cidade do São Salvador da Bahia de Todos os Santos", literally "City of the Saint Savior of the Bay of All the Saints"), on a spit of land separating the Bay of All Saints from the Atlantic. Once a monarchial stronghold dominated by agricultural, slaving, and ranching interests, Bahia is now a predominantly working-class industrial and agricultural state. The state is home to 7% of the Brazilian population and produces 4.2% of the country's GDP. Name The name of the state derives from the earlier captaincy of Bahia de Todos os Santos, named for Bay of All Saints (' in modern Portuguese), a major feature of its coastline. The bay itself was named by the explorer Ame ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
