Squaliforma
''Aphanotorulus'' is a genus of armored catfishes native to the Amazon, Orinoco, Essequibo and Jaguaribe basins in South America.Ray, C.K. & Armbruster, J.W. (2016): The genera ''Isorineloricaria'' and ''Aphanotorulus'' (Siluriformes: Loricariidae) with description of a new species. ''Zootaxa, 4072 (5): 501–539.'' They typically occur on a sand or gravel bottom in slow to moderately flowing rivers and streams, but some species occur in areas with fast current. The largest species in the genus reaches up to in standard length. Taxonomy The taxonomy of this genus has been a matter of dispute, all having been placed in ''Hypostomus'' in the past, and some occasionally placed in ''Squaliforma''. ''Squaliforma'' is now regarded as a synonym of ''Aphanotorulus'', but species west of the Andes have been moved to ''Isorineloricaria''. There are currently 7 recognized species of ''Aphanotorulus'': * '' Aphanotorulus ammophilus'' Armbruster & Page, 1996 * '' Aphanotorulus emarginatu ...

Aphanotorulus Horridus
''Aphanotorulus horridus'' is a species of catfish in the family Loricariidae. It is native to South America, where it occurs in the Madeira River basin. The species reaches 35.5 cm (14 inches) SL. It is thought to be a facultative air-breather. ''A. horridus'' was originally described as ''Hypostomus horridus'' by Rudolf Kner in 1854, although it was transferred to the genus ''Squaliforma'' (now considered invalid) after the genus' designation by Isaäc J. H. Isbrücker, I. J. H. Isbrücker, I. Seidel, J. Michels, E. Schraml, and A. Werner in 2001. In 2004, Jonathan W.

It is thought to be a facultative air-breather. ''A. gomesi'' was originally described as ''Plecostomus iheringi'' by Henry Weed Fowler in 1941, although Fowler later invalidated this name in 1942, replacing it with ''Plecostomus gomesi'' to avoid confusion with ''Plecostomus iheringii'' (a species which is currently known as '' Hypostomus iheringii'').

Isorineloricaria
''Isorineloricaria'' is a genus of catfish in the family Loricariidae from northwestern South America. They live in rivers and streams, typically with slow to moderately running water, in the Orinoco, Maracaibo, Magdalena and Guayas basins (one species in each basin). The largest species in the genus reaches up to in standard length. Taxonomy The taxonomy of this genus has been a matter of dispute, all having been placed in ''Hypostomus'' in the past, and some occasionally placed in ''Squaliforma''. ''Squaliforma'' is now regarded as a synonym of ''Aphanotorulus'', but species west of the Andes have been moved to ''Isorineloricaria''.

Hypostomus
''Hypostomus'' is a genus of catfish in the family Loricariidae. They are native to tropical and subtropical South America. '' H. plecostomus'' is the popular freshwater aquarium fish formerly known as ''Plecostomus plecostomus''. The taxonomic structure of the Loricariidae is still being expanded by scientists. ''Hypostomus'' is a highly species-rich and widely distributed catfish genus. [Baidu] |
Fish Of South America
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Most f ...

Hypostominae
The Hypostominae are a subfamily of catfishes of the family Loricariidae. Most members are restricted to tropical and subtropical South America, but there are also several species (in genera ''Ancistrus'', '' Chaetostoma'', ''Lasiancistrus'', '' Leptoancistrus'' and ''Hemiancistrus'') in southern Central America. ''Hypostomus plecostomus'', which is popular in the aquarium trade, has been introduced to several regions far from its native range. Studies conducted with representatives of some genera of Hypostominae showed, within this group, the diploid number ranges from 2n = 52 to 2n = 80. However, the supposed wide karyotypic diversity the family Loricariidae or the subfamily Hypostominae would present is almost exclusively restricted to the genus ''Hypostomus'', and the species from the other genera had a conserved diploid number.

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in flowering tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Franz Steindachner
Franz Steindachner (11 November 1834 in Vienna – 10 December 1919 in Vienna) was an Austrian Zoology, zoologist, ichthyologist, and herpetologist. He published over 200 papers on fishes and over 50 papers on reptiles and amphibians. Steindachner described hundreds of new species of fish and dozens of new amphibians and reptiles. At least seven species of reptile have been named after him. Work and career Being interested in natural history, Steindachner took up the study of fossil fishes on the recommendation of his friend Eduard Suess (1831–1914). In 1860 he was appointed to the position of director of the fish collection at the Naturhistorisches Museum, a position which had remained vacant since the death of Johann Jakob Heckel (1790–1857). (in German). Steindachner's reputation as an Ichthyology, ichthyologist grew, and in 1868 he was invited by Louis Agassiz (1807–1873) to accept a position at the Museum of Comparative Zoology at Harvard University. Steindachner took ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
