Parodontidae
The Parodontidae are a family of fresh water fish of the order Characiformes. The three genera include about 32 species, though several are undescribed. These fish are generally benthic and live in mountain streams of eastern Panama and South America. It was formerly considered a subfamily of the family Hemiodontidae. The following genera are placed in this family: * '' Apareiodon'' Eigenmann, 1916 * '' Parodon'' Valenciennes Valenciennes (, also , , ; ; or ; ) is a communes of France, commune in the Nord (French department), Nord Departments of France, department, Hauts-de-France, France.

Saccodon
''Saccodon'' is a genus of freshwater ray-finned fishes belonging to the family Parodontidae, the scrapetooths. The fishes in this genus are found in the Tumbes-Chocó-Magdalena region from Panama to northwestern Peru. Taxonomy ''Saccodon'' was first proposed as a genus by the Austrian ichthyologist Rudolf Kner in his ''Eine Uebersicht der ichthyologischen Ausbeute des Herrn Professors Dr. Mor. Wagner in Central-Amerika'' (''An overview of the ichthyological findings of Professor Dr. Mor. Wagner in Central America'') published in 1863. Kner proposed it as a monospecific genus with ''Saccodon wagneri'' as its only species, this species being the type species by monotypy. ''S. wagneri'' was first formally described, by Kner in the same volume as he proposed the genus and its type locality was given as Ecuador. ''Saccodon '' is classified within the family Parodontidae, the scrapetooths, which is classified within the suborder Characoidei of the order Characiformes. Species ''Sac ...

Apareiodon
''Apareiodon'' is a genus of freshwater ray-finned fishes belonging to the family Parodontidae, the scarpetooths. The fishies in this genus are found in the Neotropics, where they occur as far south as Río de la Plata. Taxonomy ''Apareiodon'' was first proposed as a genus by the American ichthyologist Carl H. Eigenamnn in Volume 10 of the ''Annals of Carnegie Museum'' published in 1916. When he proposed the genus Eigenmann designated ''Parodon piracicabae'' as its type species. ''P. piracicabae'' was first formally described by Eigenmann in ''An annotated list of characin fishes in the United States National Museum and the Museum of Indiana University, with descriptions of new species'' cowritten with Fletcher Ogle in volume 33 of ''Proceedings of the United States National Museum'' published in 1907 with its type locality given as Piracicaba on the Piracicaba River in Estado de São Paulo, Brazil.

Parodon
''Parodon'' is a genus of freshwater ray-finned fishes belonging to the family Parodontidae, the scrapetooths. The fishes in this genus are from the tropical and subtropical Neotropics, their distribution extending as far south as the Río de la Plata. Taxonomy ''Parodon'' was first proposed as a genus in 1850 by the French zoologist Achille Valenciennes in volume 22 of his and Georges Cuvier's '' Histoire naturelle des poissons''. Valenciennes proposed it as a monospecific genus with ''Parodon suborbitalis'' as its only species, this species being the type species by monotypy. ''P. suborbitale'' was first formally described, as ''Parodon suborbitale'', by Valenciennes in the same volume as he proposed the genus and its type locality was given as Lake Maracaibo in Venezuela. ''Parodon'' is the type genus of the family Parodontidae, the scrapetooths, which is classified within the suborder Characoidei of the order Characiformes.

Characiformes
Characiformes is an order of ray-finned fish, comprising the characins and their allies. Grouped in 18 recognized families, more than 2000 different species are described, including the well-known piranha and tetras.; Buckup P.A.: "Relationships of the Characidiinae and phylogeny of characiform fishes (Teleostei: Ostariophysi)", ''Phylogeny and Classification of Neotropical Fishes'', L.R. Malabarba, R.E. Reis, R.P. Vari, Z.M. Lucena, eds. (Porto Alegre: Edipucr) 1998:123-144. Taxonomy The Characiformes form part of a series called the Otophysi within the superorder Ostariophysi. The Otophysi contain three other orders, Cypriniformes, Siluriformes, and Gymnotiformes. The Characiformes form a group known as the Characiphysi with the Siluriformes and Gymnotiformes. The order Characiformes is the sister group to the orders Siluriformes and Gymnotiformes, though this has been debated in light of recent molecular evidence. Originally, the characins were all grouped within a sin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apareiodon Affinis
''Apareiodon affinis'', the darter characine, is a species of fresh water ray-finned fish native to the Río de la Plata Basin in southern Brazil, Paraguay and northern Argentina. Description The darter characine is a small, fusiform fish growing to a maximum length of . Like other characids, it has a mouth on the underside of the head with a poorly developed upper lip. There are no dentary teeth and the pectoral fins have a single, unbranched fin-ray which the fish uses to prop itself up on the substrate. Ecology The darter characine is an open water fish, and was one of several fish species in a reservoir on the Paraná River to thrive when large submerged macrophytes were removed. The diet consists of diatoms, green algae and the periderm of aquatic vegetation, perhaps removed accidentally while the fish scrapes off the algae. The karyotype of this fish varies between populations. In the Upper Paraná basin, the sexes have distinct diploid numbers, the males showing 2n = 5 ...

Family (biology)
Family (, : ) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...

Fresh Water
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salt (chemistry), salts and other total dissolved solids. The term excludes seawater and brackish water, but it does include non-salty mineral water, mineral-rich waters, such as chalybeate springs. Fresh water may encompass frozen water, frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/ice pellets, 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, subterranea (geography), subterranean subterranean river, rivers and underground lake, lakes. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of vascular plants and most insects, amphibians, reptiles, mammals and birds need fresh water to sur ...

Fish
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 ...

Order (biology)
Order () is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between family and class. In biological classification, the order is a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes. An immediately higher rank, superorder, is sometimes added directly above order, with suborder directly beneath order. An order can also be defined as a group of related families. What does and does not belong to each order is determined by a taxonomist, as is whether a particular order should be recognized at all. Often there is no exact agreement, with different taxonomists each taking a different position. There are no hard rules that a taxonomist needs to follow in describing or recognizing an order. Some taxa are accepted almost universally, while others are recognized only rarely. The name of an order is usually written with a capital letter. For some groups of organisms, their orders may follow consist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...
