Kritskyia Boegeri
''Kritskyia'' is a genus of monogeneans in the family Dactylogyridae. Like other monogeneans, species of ''Kritskyia'' only have one host required to complete their life cycle. In contrast to most species of monogeneans which are parasitic on the gills or on the skin of fish, species of ''Kritskyia'' are parasitic in the urinary organs of fish. The genus was created by Anna Kohn in 1990, and the definition of the genus was emended by Boeger, Tanaka and Pavanelli in 2001. The name of the genus honours the American parasitologist Delane C. Kritsky, "for his contribution to our knowledge of Brazilian Monogenea". Species Species of ''Kritskyia'' include: *'' Kritskyia moraveci'' Kohn, 1990, a parasite of the urinary bladder and ureters of the fish '' Rhamdia quelen'' (Quoy & Gaimard, 1824) (Pimelodidae, Siluriformes). The name of the species honours the Czech parasitologist František Moravec. *''Kritskyia annakohnae'' Boeger, Tanaka & Pavanelli, 2001, a parasite of the urinary ...

Czechs
The Czechs ( cs, Češi, ; singular Czech, masculine: ''Čech'' , singular feminine: ''Češka'' ), or the Czech people (), are a West Slavic ethnic group and a nation native to the Czech Republic in Central Europe, who share a common ancestry, culture, history, and the Czech language. Ethnic Czechs were called Bohemians in English until the early 20th century, referring to the former name of their country, Bohemia, which in turn was adapted from the late Iron Age tribe of Celtic Boii. During the Migration Period, West Slavic tribes settled in the area, "assimilated the remaining Celtic and Germanic populations", and formed a principality in the 9th century, which was initially part of Great Moravia, in form of Duchy of Bohemia and later Kingdom of Bohemia, the predecessors of the modern republic. The Czech diaspora is found in notable numbers in the United States, Canada, Israel, Austria, Germany, Slovakia, Ukraine, Switzerland, Italy, the United Kingdom, Australia, France, Russ ...

Salminus Brasiliensis
''Salminus brasiliensis'' (dourado, dorado, golden dorado, river tiger or jaw characin) is a large, predatory characiform freshwater fish found in central and east-central South America. Despite having ''Salminus'' in its name, the dorado is not related to any species of salmon,Miles, P.A. (24 September 2014; updated 29 November 2016)Dorado.GlobalFlyFisher. Retrieved 28 February 2017. nor to the saltwater fish also called dorado. It is very popular among recreational anglers and supports large commercial fisheries.Lima, F. C. T., and H. A.

Prochilodontidae
The Prochilodontidae, or flannel-mouthed characins, are a small family of freshwater fishes found primarily in the northern half of South America, south to Paraguay and northern Argentina. This family is closely related to the Curimatidae, and in the past they were included in Characidae. These fish have fleshy lips with rows of small teeth; their lips are able to be extended into a sucking disc. The largest species reach up to in length, and live in huge schools, making them a popular food fish. They travel upriver to spawn, and make audible grunting noises that have been described as resembling the sound of a motorbike. Species The family has around 21 species in three genera: *''Ichthyoelephas'' ** '' Ichthyoelephas humeralis'' ** '' Ichthyoelephas longirostris'' *''Prochilodus'' ** ''Prochilodus argenteus'' ** ''Prochilodus brevis'' - Brazilian bocachico ** ''Prochilodus britskii'' ** '' Prochilodus costatus'' ** '' Prochilodus hartii'' ** '' Prochilodus lacustris'' ** ''Pro ...

Prochilodus Lineatus
''Prochilodus lineatus'', the streaked prochilod, is a species of ray-finned fish in the family Prochilodontidae. It is native to the Paraná—Paraguay and Paraíba do Sul river basins in South America. It performs long breeding migrations and supports very important fisheries. Local names In Spanish its common name is ''sábalo''; in Brazil it receives the names ''curimbatá'', ''curimba'', ''corimbatá'' or ''grumatã''.In the United States it is also known by the technical synonym ''Tarpon prochilodus''. There are mother species of fish with the common name '' sábalo''; ''P. lineatus'' is therefore distinguished sometimes as ''sábalo jetón'' (colloquial Spanish for "big-mouth") or ''chupabarro'' ("mud-sucker"). Appearance ''P. lineatus'' reaches up to in length and in weight. A common length is about . Its body is tall and compressed, greenish-gray (lighter in the belly), with yellowish green fins. Its mouth is circular and projects towards the front; it has two seri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Brazilians
Brazilians ( pt, Brasileiros, ) are the citizens of Brazil. A Brazilian can also be a person born abroad to a Brazilian parent or legal guardian as well as a person who acquired Brazilian citizenship. Brazil is a multiethnic society, which means that it is home to people of many ethnic origins, and there is no correlation between one's stock and their Brazilian identity. Being Brazilian is a civic phenomenon, rather than an ethnic one. As a result, the degree to which Brazilian citizens identify with their ancestral roots varies significantly depending on the individual, the region of the country, and the specific ethnic origins in question. Most often, however, the idea of ethnicity as it is understood in the anglophone world is not popular in the country. In the period after the colonization of the Brazilian territory by Portugal, during much of the 16th century, the word "Brazilian" was given to the Portuguese merchants of Brazilwood, designating exclusively the name of ...

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 single ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Serrasalmidae
The Serrasalmidae (serrasalmids) are a family of characiform fishes, recently elevated to family status. It includes more than 90 species. The name means "serrated salmon family", which refers to the serrated keel running along the belly of these fish. Fish classified as Serrasalmidae are also known by these common names: pacu, piranha, and silver dollar. These common names generally designate differing dental characteristics and feeding habits. Description Serrasalmids are medium- to large-sized characiform fishes that reach about long, generally characterized by a deep, laterally compressed body with a series of midventral abdominal spines or scutes, and a long dorsal fin (over 16 rays). Most species also possess an anteriorly directed spine just before the dorsal fin extending from a supraneural bone; exceptions include members of the genera ''Colossoma'', ''Piaractus'', and ''Mylossoma''. Most serrasalmids have about 60 chromosomes, ranging from 54 to 62.''Metynnis'' has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Serrasalmus Spilopleura
''Serrasalmus'' is a genus of piranhas. They are collectively known as pirambebas; the "typical" piranhas like the piraya piranha are nowadays placed in ''Pygocentrus''. Like all piranhas, ''Serrasalmus'' are native to South America. These fish are predatory, have sharp teeth and generally have a rhomboid shape. In some, the shape is more ovoid, particularly in old specimens. Some ''Serrasalmus'' species can exceed (''S. manueli'' and ''S. rhombeus'', according to OPEFE), placing them among the largest Serrasalmidae. Species There are at least 31 recognized species in this genus: * ''Serrasalmus altispinis'' Merckx, Jégu & dos Santos, 2000 * ''Serrasalmus altuvei'' Ramírez, 1965 (''caribe pinche'') * ''Serrasalmus auriventris'' ( Burmeister, 1861) * ''Serrasalmus brandtii'' Lütken, 1875 (white piranha) * ''Serrasalmus compressus'' Jégu, Leão & dos Santos, 1991 * ''Serrasalmus eigenmanni'' Norman, 1929 * ''Serrasalmus elongatus'' Kner, 1858 (slender piranha, ''cari ...
