Species There are currently three recognized species in this genus: * '' Stegophilus insidiosus'' Reinhardt, 1859 * '' Stegophilus panzeri'' ( Ahl, 1931) * '' Stegophilus septentrionalis'' Myers, 1927 ''S. insidiosus'' originates from the São Francisco River basin in Brazil, ''S. panzeri'' is from the lower Amazon River basin in Brazil, and ''S. septentrionalis'' is from Orinoco River basin in Venezuela. ''Stegophilus'' species grow to between 4.1–4.4 centimetres (1.6–1.7 in) SL. ''S. insidiosus'' is a true parasite living in the gill chambers of larger fishes, including catfishes like ''Sorubim lima ''Sorubim lima'' is a species of fish of the Pimelodidae family in the order Siluriformes. Morphology Males can reach 54.2 cm in total length and 1,300 g in weight. Their body is devoid of scales and covered with bone plaques. It has an irreg ...''; it uses its strong teeth to bi ...

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 ...

Johannes Theodor Reinhardt
Johannes Theodor Reinhardt (3 December 1816, in Copenhagen – 23 October 1882, in Frederiksberg) was a Danish zoologist and herpetologist. The son of Johannes Christopher Hagemann Reinhardt. Biography He participated as botanist in the first Galathea Expedition (1845—1847). In 1848 he became a curator at the ''Kongelige Naturhistoriske Museum'' in Copenhagen (now University of Copenhagen Zoological Museum). He taught classes in zoology at the '' Danmarks Tekniske Universitet'' (1856–1878) and at the University of Copenhagen (1861–1878). In 1854 he received the title of professor.Darwinarkivet Biographies; Johannes Theodor Reinhardt. During the 1840s and 1850s he periodically worked in |
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 (shark Sharks are a group of elasmobranch fish chara ...

Freshwater Fish Genera
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 ...

Fish Of Venezuela
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 ...
