Caecorhamdella Brasiliensis
''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 (), or simply the Ribeira River (), is a river of Paraná (state), Paraná and São Paulo (state), São Paulo states in southeastern Brazil. It flows into the Atlantic Ocean near Iguape. The river is home to several end .... 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 w ...

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 re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Fish Described In 1907
A fish (: fish or fishes) is an aquatic animal, aquatic, Anamniotes, anamniotic, gill-bearing vertebrate animal with swimming fish fin, fins and craniate, a hard skull, but lacking limb (anatomy), limbs with digit (anatomy), digits. Fish can be grouped into the more basal (phylogenetics), basal jawless fish and the more common jawed fish, the latter including all extant taxon, living cartilaginous fish, cartilaginous and bony fish, as well as the extinct placoderms and acanthodians. In a break to the long tradition of grouping all fish into a single Class (biology), class (Pisces), modern phylogenetics views fish as a paraphyletic group. Most fish are ectotherm, cold-blooded, their body temperature varying with the surrounding water, though some large nekton, active swimmers like white shark and tuna can hold a higher core temperature. Many fish can communication in aquatic animals#Acoustic, communicate acoustically with each other, such as during courtship displays. The stud ...

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 species have very small ranges and are threatened.Fenolio, D.B.; Zhao, Y.; Niemiller, M.L.; and Stout, J. (2013).

Catfish Of Brazil
Catfish (or catfishes; order Siluriformes or Nematognathi) are a diverse group of ray-finned fish. Catfish are named for their prominent 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 scale-less, with neither the armour-plated nor the naked species having scales. This order of fish are defined by features of the skull and swimbladder. 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 detritivorous and scavenging bottom feeders, down to tiny ectoparasitic species known as the candirus. In the Southern United States, catfish species may be known by a variety of slang names, such as "mud cat", "polliwogs", or "chuckleheads". These nicknames are not standardized, so one area may call a bullhead catfish by the nic ... [...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 Taxonomy (biology), 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 troglobite, troglobitic catfishes, ''P. kronei'' and ''P. spelaea''. Species There are currently 81 recognized species in this genus: * ''Pimelodella altipinnis'' (Franz Steindachner, Steindachner, 1864) * ''Pimelodella australis'' Carl H. Eigenmann, C. H. Eigenmann, 1917 * ''Pimelodella avanhandavae'' Carl H. Eigenmann, C. H.

Ribeira De Iguape River
The Ribeira de Iguape River (), or simply the Ribeira River (), is a river of Paraná (state), Paraná and São Paulo (state), 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 (state), 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 th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Endemism
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or b ...
