Ammoglanis
''Ammoglanis'' is a genus of pencil catfishes native to South America. Taxonomy The phylogenetic position of ''A. pulex'' is problematic. It seems to be closely related to ''A. diaphanus'' due to some derived characters of the internal anatomy, but a conclusive assessment of its relationships has not been prevented by its paedomorphic features and scarcity of study material. This generic placement seems to be well supported. The relationships of the genus ''Ammoglanis'' are unknown; it is thought that this genus along with undescribed forms are the sister group to a large intrafamilial clade composed of several genera and subfamilies. In the interim, this genus is included within Sarcoglanidinae. Species There are currently five recognized species in this genus: * '' Ammoglanis amapaensis'' Mattos, Costa & Gama, 2008 * '' Ammoglanis diaphanus'' Costa, 1994 *'' Ammoglanis natgeorum'' *'' Ammoglanis obliquus'' * '' Ammoglanis pulex'' de Pinna & Winemiller, 2000 Dist ...

Ammoglanis Obliquus
''Ammoglanis obliquus'' is a species of pencil catfish endemism, endemic to the Preto da Eva River, Rio Preto da Eva drainage in the central Brazilian Amazon. This species reaches a length of . Description ''Ammoglanis obliquus'', a minute catfish species reaching a maximum adult size of 15.5 mm, is described from the Rio Preto da Eva drainage in the central Brazilian Amazon. It is distinguished from all of its congeners in possessing an exclusive combination of character states, including the presence and number of premaxillary and dentary teeth, number of interopercular and opercular odontodes, presence of cranial fontanel, number of dorsal-fin rays, number of anal-fin rays, number of caudal-fin rays, number of pelvic-fin rays, number of pectoral-fin rays, absence of pelvic splint, antorbital morphology, and absence of supraorbital and autopalatine morphology.

Sarcoglanidinae
The Sarcoglanidinae are a subfamily of catfishes (order Siluriformes) of the family Trichomycteridae. It includes six genera: '' Ammoglanis'', '' Malacoglanis'', '' Microcambeva'', '' Sarcoglanis'', '' Stauroglanis'', and '' Stenolicmus''. Taxonomy The subfamily Sarcoglanidinae was first established in 1966 for ''Sarcoglanis simplex'' and ''Malacoglanis gelatinosus''. A third species of the subfamily, ''Stauroglanis gouldingi'', was described about 25 years later. Descriptions of additional species have followed, though most genera remain monotypic. The relationships of the genus ''Ammoglanis'' with other sarcoglanidines are not well-established; however, this genus is currently included within Sarcoglanidinae. This subfamily has been proposed to have a sister group relationship to Glanapteryginae. Like the members of this subfamily, many glanapterygines are sand-dwelling fish. Distribution and habitat All genera except ''Microcambeva'' are endemic to the Amazon River; ''Microcam ...

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 ...

Araguari River (Amapá)
The Araguari River ( pt, Rio Araguari) is the primary river of Amapá state in north-eastern Brazil. It became famous among surfers when some decided to ride its constant tidal bore, characterizing waves that can last for several minutes. In 2013, three dams were built in the river to generate hydroelectricity. The dams ended the tidal bore which altered the flow of water in the Amazon, and caused significant land erosion and damage to the Bailique Archipelago. The river flows through the Uatuma-Trombetas moist forests ecoregion. The river defines the western boundary of the Amapá National Forest, a sustainable use conservation unit created in 1989.

Araguaia River
The Araguaia River ( pt, Rio Araguaia , Karajá: ♂ ''Berohokỹ'' eɾohoˈkə̃ ♀ ''Bèrakuhukỹ'' ɛɾakuhuˈkə̃ is one of the major rivers of Brazil though it is almost equal in volume at its confluence with the Tocantins. It has a total length of approximately 2,627 km. Geography The Araguaia River comes from Goiás-Mato Grosso south borders. From there it flows northeast to a junction with the Tocantins near the town of São João. Along its course, the river forms the border between the states of Goiás, Mato Grosso, Tocantins and Pará. Roughly in the middle of its course the Araguaia splits into two forks (with the western one retaining the name Araguaia and the eastern one being called the Javaés River). These later reunite, forming the Ilha do Bananal, the world's largest river island. The vein of the Javaés forms a broad inland where it pours back into the main Araguaia, a 100,000 hectare expanse of igapós or flooded forest, blackwater river channels, an ...
