Dasyloricaria
''Dasyloricaria'' is a genus of armored catfishes native to Central and South America. The distribution of these species includes the northwestern South America on the Pacific slope of Colombia and Panama. Its distribution is restricted to the Pacific slope of the Andes, which is a unique pattern of distribution within the subfamily. Species There are currently 3 recognized species in this genus: * '' Dasyloricaria filamentosa'' ( Steindachner, 1878) * '' Dasyloricaria latiura'' ( C. H. Eigenmann & Vance, 1912) * '' Dasyloricaria paucisquama'' Londoño-Burbano & R. E. dos Reis, 2016 Londoño-Burbano, A. & Reis, R.E.

Dasyloricaria Paucisquama
''Dasyloricaria paucisquama'' is a species of catfish in the family Loricariidae. It is native to South America, where it occurs in the upper and middle Magdalena River basin in Colombia. The species reaches 20.3 cm (8 inches) in standard length. Its specific epithet, ''paucisquama'', is derived from Latin Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages.

Loricariini
Loricariinae is a subfamily of the family Loricariidae of catfish (order Siluriformes). This subfamily is divided into two tribes and about 30 genera. They are mainly native to freshwater habitats in South America, but there are also several species (in genera '' Crossoloricaria'', '' Dasyloricaria'', '' Fonchiiichthys'', '' Rineloricaria'', '' Spatuloricaria'', ''Sturisoma'' and '' Sturisomatichthys'') in Panama and a single (''Fonchiiichthys'') in Costa Rica.Angulo; Garita-Alvarado; Bussing; and López (2013).

Loricaria
''Loricaria'' is a genus of armored catfish native to South America. Taxonomy ''Loricaria'' was the first genus of the family Loricariidae described. Thus, it is the nominal genus of the family Loricariidae. Phylogenetic relationships within ''Loricaria'' and among other members of Loricariini remain uncertain. Its external morphology shows few shared derived characters, making comparison with other genera difficult. ''Loricaria'' has been hypothesized to occupy a basal position among members of the subtribe Loricariina, with the other genera possessing derived characters. Based on the characteristics of its mouth, ''Loricaria'' appears to maintain a close relationship with representatives of the '' Pseudohemiodon'' group. ''Proloricaria'' is considered a synonym of ''Loricaria''. Species These are the currently recognized species in this genus: * '' Loricaria apeltogaster'' Boulenger, 1895 * '' Loricaria birindellii'' M. R. Thomas & Sabaj Pérez, 2010 * '' Loricaria cata ...

Loricariichthys
''Loricariichthys'' is a genus of catfishes ( order Siluriformes) of the family Loricariidae. Taxonomy This genus is part of the ''Loricariichthys'' group within the subfamily Loricariinae; this group also includes the genera '' Furcodontichthys'', ''Hemiodontichthys'', '' Limatulichthys'', and '' Pseudoloricaria''. ''Loricariichthys'' seems to be intermediate between ''Limatulichthys'' and ''Pseudoloricaria'' on one hand, and ''Furcodontichthys'' and ''Hemiodontichthys'' on the other. Although this genus is well diagnosed, the species are very similar and difficult to identify. Species There are currently 18 recognized species in this genus: * '' Loricariichthys acutus'' (Valenciennes, 1840) * '' Loricariichthys anus'' (Valenciennes, 1835) * '' Loricariichthys brunneus'' (Hancock, 1828) * '' Loricariichthys cashibo'' ( C.

Odontode
Odontodes, or dermal teeth, are hard structures found on the external surfaces of animals or near internal openings. They consist of a soft pulp surrounded by dentine and covered by a mineralized substance such as enamel, a structure similar to that of teeth. They generally do not have the same function as teeth, and are not replaced the same way teeth are in most fish. In some animals (notably catfish), the presence or size of odontodes can be used in determining the sex. Odontodes typically cover the body of chondrichthyans (cartilaginous fishes), while mineralized dermal scales are characteristic of bony fishes. During the evolution to bony fishes, ancestral odontodes have been modified to become dermal scales, including elasmoid scales in teleosteans. Etymology The name comes from the Greek "''odous, gen.

Rineloricaria
''Rineloricaria'' (from the Greek, ''rhinos'' meaning ''nose'', and the Latin, ''lorica'' meaning ''cuirass of leather'') is a genus of freshwater tropical catfish ( order Siluriformes) belonging to the family Loricariidae. They are commonly called whiptail catfish because of the long filament that grows out of the tip of the caudal fin that is characteristic of the genus. With the exception of '' R. altipinnis'' from Panama, they are native to the rivers of northern and central South America. Some species are regularly seen in the aquarium trade. Taxonomy This genus was described by Pieter Bleeker in 1862, with ''R. lima'' as the type species. This genus is by far one of the most speciose of the subfamily Loricariinae, containing about 30 species. On the other hand, it is one of the least resolved genera. In 2008, 14 new species were added to this genus. ''Hemiloricaria'', '' Fonchiiichthys'', and ''Leliella'' been variably considered synonyms of ''Rineloricaria''; these gene ...

Sexual Dimorphism
Sexual dimorphism is the condition where the sexes of the same animal and/or plant species exhibit different morphological characteristics, particularly characteristics not directly involved in reproduction. The condition occurs in most animals and some plants. Differences may include secondary sex characteristics, size, weight, colour, markings, or behavioural or cognitive traits. These differences may be subtle or exaggerated and may be subjected to sexual selection and natural selection. The opposite of dimorphism is ''monomorphism'', which is when both biological sexes are phenotypically indistinguishable from each other. Overview Ornamentation and coloration Common and easily identified types of dimorphism consist of ornamentation and coloration, though not always apparent. A difference in coloration of sexes within a given species is called sexual dichromatism, which is commonly seen in many species of birds and reptiles. Sexual selection leads to the exaggerated dim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
