Hypostomus arecuta ( 英語 )

由wikipedia EN提供

Hypostomus arecuta[1] is a species of catfish in the family Loricariidae.[2] It is a freshwater fish native to South America, where it occurs in the Paraná River in Argentina.[3]

H. arecuta is typically found in coastal areas of the main river channel, in areas with a high oxygen concentration, moderate currents (around 0.6 m/s) and substrates composed of sand, pebbles, and large sandstone boulders. The water in which H. arecuta occurs is reported to usually have a transparency of 1.5 to 2.4 m (possibly referring to visibility) and a conductivity of 50.9 to 59.6 μS/cm.[3]

H. arecuta reaches 24.3 cm (9.6 inches) SL and is believed to be a facultative air-breather. It is known to be sympatric with multiple other Hypostomus species, including H. commersoni, H. cochliodon, H. uruguayensis, H. latifrons, H. ternetzi, H. luteomaculatus, H. microstomus, and H. boulengeri. Its specific epithet, arecuta, derives from the Guarani word arecutá, which means "loricariid fish".[3]

Hypostomus arecuta ( 西班牙、卡斯蒂利亞西班牙語 )

由wikipedia ES提供

Hypostomus arecuta es una especie de pez de agua dulce del género Hypostomus de la familia Loricariidae, en el orden de los Siluriformes. Se distribuye en el centro-sur de Sudamérica.[1]

Los machos pueden llegar alcanzar los 24,3 cm de longitud total.[1]

Taxonomía

Esta especie fue descrita originalmente en el año 2012 por los ictiólogos Yamila Paula Cardoso, Adriana Edith Almirón, Jorge Rafael Casciotta, Danilo Ramón Aichino, Marta Susana Lizarralde y Juan Ignacio Montoya-Burgos.[2]

Etimología

Etimológicamente Hypostomus se construye con dos palabras del idioma griego, en donde: hipo significa 'bajo' y estoma que es 'boca'.[3]​ El término específico arecuta refiere al nombre con que los aborígenes guaraníes denominaban en su idioma a los loricáridos: arecutá.[1]

Distribución y hábitat

Esta especie se distribuye en el nordeste de la Argentina.[1]​ Es endémica de la ecorregión de agua dulce Paraná inferior.

Se encuentra en las zonas costeras que bordean el canal principal del río Paraná. Es una especie típica recorredora del fondo, el que está compuesto por grandes piedras de areniscas con sectores donde domina la arena o los guijarros. Las aguas donde habita son bien oxigenadas y poseen una velocidad de corriente moderada, con transparencia de 1,5 a 2,40 m. Comparte su hábitat con numerosas especies de loricáridos, y centrándose solo en sus congéneres, allí también viven: Hypostomus boulengeri H. cochliodon, H. commersoni, H. latifrons, H. luteomaculatus, H. microstomus, H. ternetzi y H. uruguayensis.
