Deuterodon Heterostomus
''Deuterodon heterostomus'' is a small species of characin endemic to a large river system in southeast Brazil. It was originally the only member of the genus ''Probolodus'', but ''Probolodus'' is now considered obsolete, synonymized with ''Deuterodon''. Much like other members of ''Deuterodon'', and like some fish in related genera, ''D. heterostomus'' is a small, silvery fish with fins in some combination of red and clear. It has a defined humeral spot that can be used for identification. Its diet was not well-known until a 1970 study that classified it as a voracious lepidophage, preying on other fish species for their scales. Most of its food is sourced from related fishes such as ''Psalidodon fasciatus'', a cryptic species to which ''D. heterostomus'' bears a strong visual resemblance. This resemblance has been proposed to be a form of mimicry, allowing ''D. heterostomus'' to easily approach its prey. Taxonomy When originally described by German-American ichyhtologist Ca ...

Deuterodon
''Deuterodon'' is a genus of characins from river basins in southern and southeastern Brazil ( Rio Grande do Sul to Espírito Santo), with a single species of uncertain taxonomic status, ''D. potaroensis'', from Guyana. These are small fish that reach up to in total length. They are omnivores with a specialized mouth structure that allows them to scrape algae and debris off bedrock. Species formerly considered members of the genera ''Probolodus'' and ''Myxiops'' are considered to be members of ''Deuterodon'' by modern researchers, following a thorough phyletic review of several characid genera in 2020. Species The following 24 species are recognized in the genus ''Deuterodon'':Silva, P.C.; M.C. Malabarba; L.R.

Humeral Spot
Humeral spot (from Latin ''humerus'', pertaining to the shoulder) is a mark or pattern found on several species of fish, typically above the pectoral fin Fins are distinctive anatomical features composed of bony spines or rays protruding from the body of a fish. They are covered with skin and joined together either in a webbed fashion, as seen in most bony fish, or similar to a flipper, as .... In insects, the humeral spot may be found on the costal area of the wing. References {{Animal-physiology-stub Humerus Fish physiology Insect physiology ...

Lepidophagy
Lepidophagy is a specialised feeding behaviour in fish that involves eating the scales of other fish. Lepidophagy is widespread, having evolved independently in at least five freshwater families and seven marine families. A related feeding behavior among fish is pterygophagy: feeding on the fins of other fish. Species Lepidophagy, or scale-eating, has been reported in a range of fish, including: '' Chanda nama'' (family Ambassidae), '' Plagiotremus'' (family Blenniidae), '' Terapon jarbua'' (family Terapontidae), a few '' Ariopsis'' and '' Neoarius'' species (family Ariidae), Pachypterus khavalchor (family Pachypteridae), Macrorhamphoides uradoi (family Triacanthodidae), several pencil catfish (family Trichomycteridae), some piranha, ''Exodon paradoxus'', '' Probolodus'', '' Roeboides'' and '' Roeboexodon'' species (order Characiformes), '' Cyprinodon desquamator'' (family Cyprinodontidae), along with both '' Perissodus'' species, all four '' Plecodus'' species, '' Xenoc ...

Standard Length
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 characterize ...

Brazil
Brazil ( pt, Brasil; ), officially the Federative Republic of Brazil (Portuguese: ), is the largest country in both South America and Latin America. At and with over 217 million people, Brazil is the world's fifth-largest country by area and the seventh most populous. Its capital is Brasília, and its most populous city is São Paulo. The federation is composed of the union of the 26 states and the Federal District. It is the largest country to have Portuguese as an official language and the only one in the Americas; one of the most multicultural and ethnically diverse nations, due to over a century of mass immigration from around the world; and the most populous Roman Catholic-majority country. Bounded by the Atlantic Ocean on the east, Brazil has a coastline of . It borders all other countries and territories in South America except Ecuador and Chile and covers roughly half of the continent's land area. Its Amazon basin includes a vast tropical forest, ho ...

Fish Described In 1911
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 ...

Taxa Named By Carl H
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 wate ...
