Pimelodella Kronei
''Pimelodella kronei'' is a species of three-barbeled catfish endemic to Brazil. Discovered by the German naturalist Sigismund Ernst Richard Krone, it was the first troglobitic fish described in Brazil, but several others have been described later. Description ''Pimelodella kronei'' is an endemic troglobitic species, so exclusively subterranean, found in cave streams along the Betari River basin, a tributary of the upper Ribeira de Iguape River The Ribeira de Iguape River ( pt, Rio Ribeira de Iguape), or simply the Ribeira River ( pt, Rio Ribeira), is a river of Paraná and São Paulo states in southeastern Brazil. It flows into the Atlantic Ocean near Iguape. The river is home to sever .... The species is adapted to food scarcity typical of the underground and seems to be in the midst of a process of loss of cryptobiotic habits - the blind catfish are little or no photophobic and spend a lot of time actively exploring the whole environment, not only the bottom but also the wat ...

Alípio De Miranda-Ribeiro
Alípio de Miranda-Ribeiro (21 February 1874, Rio Preto, Minas Gerais – 8 January 1939) was a Brazilian herpetologist and ichthyologist. His son, Paulo de Miranda-Ribeiro (1901-1965) was also a zoologist. From an early age Alípio de Miranda-Ribeiro had a passion for natural history; as an adolescent he translated works of Buffon into Portuguese. He studied medicine in Rio de Janeiro, and from 1894 worked as a preparator at the National Museum of Brazil. Here he later served as secretary (from 1899), and director of the department of zoology (from 1929). During his career he explored the Amazon region many times, and under the direction of Candido Rondon (1865-1958), he took part in installing the first telegraph through the Amazon and Mato Grosso. In 1911, after visiting museums and fishery programs in Europe and the United States, he founded a fisheries inspectorate in Brazil, the first official services on fisheries in the nation. In 1911 he published the highly regarde ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pimelodella
''Pimelodella'' is a genus of three-barbeled catfishes. ''Pimelodella'' is the largest genus in the family. However, it is in need of taxonomic revision. This genus is found on both sides of the Andes, ranging from Panama to Paraguay and southern Brazil. With the exception of ''P. chagresi'', all members of the genus are restricted to South America. This genus includes two species of troglobitic catfishes, ''P. kronei'' and ''P. spelaea''. Species There are currently 78 recognized species in this genus: * '' Pimelodella altipinnis'' ( Steindachner, 1864) * '' Pimelodella australis'' C. H. Eigenmann, 1917 * '' Pimelodella avanhandavae'' C. H. Eigenmann, 1917 * '' Pimelodella boliviana'' C. H. Eigenmann, 1917 * '' Pimelodella boschmai'' van der Stigchel, 1964 * '' Pimelodella brasiliensis'' ( Steindachner, 1877) * '' Pimelodella breviceps'' ( Kner, 1858) * '' Pimelodella buckleyi'' ( Boulenger, 1887) * '' Pimelodella chagresi'' ( Steindachner, 1876) * '' Pimelodella chaparae'' ...

Fish Described In 1907
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 ...

Cave Fish
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).

Freshwater Fish Of Brazil
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. Although the term specifically excludes seawater and brackish water, it does include non- salty mineral-rich waters such as chalybeate springs. Fresh water may encompass frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/ sleet and graupel, and surface runoffs that form inland bodies of water such as wetlands, ponds, lakes, rivers, streams, as well as groundwater contained in aquifers, subterranean rivers and lakes. Fresh water is the water resource that is of the most and immediate use to humans. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of higher plants and most insects, amphibians, reptiles, mammals and birds need fresh water to survive. Fresh water is ...

Endemic Fish Of Brazil
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Catfish Of South America
Catfish (or catfishes; order Siluriformes or Nematognathi) are a diverse group of ray-finned fish. Named for their prominent barbels, which resemble a cat's whiskers, catfish range in size and behavior from the three largest species alive, the Mekong giant catfish from Southeast Asia, the wels catfish of Eurasia, and the piraíba of South America, to detritivores (species that eat dead material on the bottom), and even to a tiny parasitic species commonly called the candiru, ''Vandellia cirrhosa''. Neither the armour-plated types nor the naked types have scales. Despite their name, not all catfish have prominent barbels or "whiskers". Members of the Siluriformes order are defined by features of the skull and swimbladder. Catfish are of considerable commercial importance; many of the larger species are farmed or fished for food. Many of the smaller species, particularly the genus ''Corydoras'', are important in the aquarium hobby. Many catfish are nocturnal, [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish Measurement
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 meas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ribeira De Iguape River
The Ribeira de Iguape River ( pt, Rio Ribeira de Iguape), or simply the Ribeira River ( pt, Rio Ribeira), is a river of Paraná and São Paulo states in southeastern Brazil. It flows into the Atlantic Ocean near Iguape. The river is home to several endemic species of fish. So far no dams have been built on the river, although four have been proposed. Although it flows through a relatively sparsely populated region with untouched areas of Atlantic Forest, the river has been contaminated with heavy metals from mining beyond the point where it is considered safe to eat the molluscs found in the river and its estuary. Course The Ribeira de Iguape River is long, and is the largest in São Paulo to have no dams along its length. It forms at the confluence of the Ribeirinha River and the Açunguí River in the state of Paraná less than from Curitiba. The elevation at its origin is about . The main source is in the Campos Gerais National Park. About of the river is in the state ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
