Copionodontinae
The Copionodontinae are a subfamily of catfishes (order Siluriformes) of the family Trichomycteridae. It includes two genera, '' Copionodon'' and ''Glaphyropoma''. Classification Copionodontines are remarkably primitive in body form, and lack many of the synapomorphies previously used to diagnose the family Trichomycteridae. Little doubt exists that the Copionodontinae form a monophyletic group, diagnosed by several unambiguous synapomorphies, including a unique dentition composed of spatulate teeth not seen anywhere else in the Trichomycteridae. A few characters also support the genera ''Copionodon'' and ''Glaphyropoma'' as monophyletic subunits. Distribution and ecology Copionodontines occur exclusively in the Chapada Diamantina; though the plateau is drained by four river basins, so far, these fish are exclusively found in drainages associated with the Paraguaçu River The Paraguaçu River () is a river in Bahia state of eastern Brazil. It runs from the Chapada Diamantina ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trichomycteridae
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 cl ...

Glaphyropoma
''Glaphyropoma'' is a genus of small pencil catfishes native to Bahia in Brazil. Species There are currently two recognized species in this genus: * '' Glaphyropoma rodriguesi'' de Pinna, 1992 * '' Glaphyropoma spinosum'' Bichuette, de Pinna & Trajano, 2008 The single synapomorphy proposed for ''Glaphyropoma'' is the marked narrowing of the first hypobranchial, giving the hypobranchial a slender shape. ''G. rodriguesi'' grows to about 5.1 centimetres (2.0 in) in standard length and originates from the Mucujê River, a tributary of Paraguaçu River in Brazil. ''G. spinosum'' is known to grow as large as 5.8 cm (2.3 in) in standard length. It is known from subterranean waters in the Diamantina Plateau of the Bahia State in central northeastern Brazil. This is the first-known troglomorphic species in the subfamily Copionodontinae. These fish live in quartzitic caves formed by erosion Erosion is the action of surface processes (such as water flow or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. 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 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. phylogenetic analysis should c ...

Subfamily
In biological classification, a subfamily ( Latin: ', plural ') is an auxiliary (intermediate) taxonomic rank, next below family but more inclusive than genus. Standard nomenclature rules end subfamily botanical names with "-oideae", and zoological names with "-inae". See also * International Code of Nomenclature for algae, fungi, and plants The ''International Code of Nomenclature for algae, fungi, and plants'' (ICN) is the set of rules and recommendations dealing with the formal botanical names that are given to plants, fungi and a few other groups of organisms, all those "trad ... * International Code of Zoological Nomenclature * Rank (botany) * Rank (zoology) Sources {{biology-stub ...

Catfish
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] |

Synapomorphy
In phylogenetics, an apomorphy (or derived trait) is a novel character or character state that has evolved from its ancestral form (or plesiomorphy). A synapomorphy is an apomorphy shared by two or more taxa and is therefore hypothesized to have evolved in their most recent common ancestor. ) In cladistics, synapomorphy implies homology. Examples of apomorphy are the presence of erect gait, fur, the evolution of three middle ear bones, and mammary glands in mammals but not in other vertebrate animals such as amphibians or reptiles, which have retained their ancestral traits of a sprawling gait and lack of fur. Thus, these derived traits are also synapomorphies of mammals in general as they are not shared by other vertebrate animals. Etymology The word —coined by German entomologist Willi Hennig—is derived from the Ancient Greek words (''sún''), meaning "with, together"; (''apó''), meaning "away from"; and (''morphḗ''), meaning "shape, form".

Monophyly
In cladistics for a group of organisms, monophyly is the condition of being a clade—that is, a group of taxa composed only of a common ancestor (or more precisely an ancestral population) and all of its lineal descendants. Monophyletic groups are typically characterised by shared derived characteristics (synapomorphies), which distinguish organisms in the clade from other organisms. An equivalent term is holophyly. The word "mono-phyly" means "one-tribe" in Greek. Monophyly is contrasted with paraphyly and polyphyly as shown in the second diagram. A ''paraphyletic group'' consists of all of the descendants of a common ancestor minus one or more monophyletic groups. A '' polyphyletic group'' is characterized by convergent features or habits of scientific interest (for example, night-active primates, fruit trees, aquatic insects). The features by which a polyphyletic group is differentiated from others are not inherited from a common ancestor. These definitions have take ...

Dentition
Dentition pertains to the development of teeth and their arrangement in the mouth. In particular, it is the characteristic arrangement, kind, and number of teeth in a given species at a given age. That is, the number, type, and morpho-physiology (that is, the relationship between the shape and form of the tooth in question and its inferred function) of the teeth of an animal. Animals whose teeth are all of the same type, such as most non-mammalian vertebrates, are said to have '' homodont'' dentition, whereas those whose teeth differ morphologically are said to have ''heterodont'' dentition. The dentition of animals with two successions of teeth (deciduous, permanent) is referred to as ''diphyodont'', while the dentition of animals with only one set of teeth throughout life is ''monophyodont''. The dentition of animals in which the teeth are continuously discarded and replaced throughout life is termed ''polyphyodont''. The dentition of animals in which the teeth are set in soc ...

Chapada Diamantina
Chapada Diamantina (; Portuguese for the "Diamond Plateau") is a region of Bahia state, in the Northeast of Brazil. This mountain range is known as “Serra do Espinhaço,” in Minas Gerais state, south of Bahia. Description The Chapada Diamantina lies at the center of Bahia State and forms the northern part of the Espinhaço Mountain Range. It has approximately and encompasses 58 municipalities. Technically this region is considered a part of the caatinga biome, and contains some of its highest elevations, most of it above . The vegetation; a product of the physiographic conditions, is known as cerrado, and consists of rocky plains, dry forests, and caatinga desert vegetation, all of which harbour a great deal of biodiversity and unique endemisms. The region is considered to have a Mesotermic climate, of the Cwb type, according to Köppen Climate classifications. It is normally quite cooler than its surrounding areas, with an average annual temperature under 22 °C. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
