Apteronotus Mariae
''Apteronotus'' is a genus of weakly electric knifefish in the family Apteronotidae, distinguished by the presence of a tiny tail fin. This genus is restricted to tropical and subtropical South America (Amazon, Orinoco, RÃo de la Plata and Magdalena basins, as well as rivers in western Colombia and the Guianas) and Panama where found in a wide range of freshwater habitats. They feed on small animals. Depending on the exact species, they reach a total length of up to about . Although it has been claimed that ''A. magdalenensis'' is up to long, this is not supported by recent studies and likely the result of confusion with ''Sternopygus aequilabiatus''. Members of ''Apteronotus'' fall into three species groups based on their morphology: the ''A. albifrons'' group have a rounded snout and are black or dark brown with a contrasting light stripe on the top of the head, and bands on the tail and at its base, the ''A. leptorhynchus'' group have an elongate, slender snout (espec ...

Black Ghost Knifefish
The black ghost knifefish (''Apteronotus albifrons'') is a tropical fish belonging to the ghost knifefish Family (biology), family (Apteronotidae). They originate in freshwater habitats in South America where they range from Venezuela to the Paraguay River, Paraguay–Paraná River, including the Amazon Basin. They are popular in aquarium, aquaria. The fish is all black except for two white rings on its tail, and a white blaze on its nose, which can occasionally extend into a stripe down its back. It moves mainly by undulating a long fin on its underside. It will grow to a maximum length of . and can grow bigger depending on the type of food. Black ghost knifefish are Nocturnality, nocturnal.

Sternopygus
''Sternopygus'' is a genus of glass knifefishes found in tropical and subtropical South America (south to the RÃo de la Plata Basin), and Panama. They inhabit a wide range of freshwater habitats, from fast-flowing rivers to essentially static waters in floodplains, and shallow habitats to the bottom of deep rivers. ''S. macrurus'' will even visit brackish mangrove to feed. They are medium to large knifefish, with a maximum total length of depending on the exact species. They feed on invertebrates, small fish and fruits. Most members of Gymnotiformes are nocturnal, but ''Sternopygus'' are both nocturnal and diurnal. Species There are currently ten recognized species in this genus. * '' Sternopygus aequilabiatus'' ( Humboldt, 1805) * '' Sternopygus arenatus'' ( Eydoux & Souleyet, 1850) * '' Sternopygus astrabes'' Mago-Leccia, 1994 * '' Sternopygus branco'' Crampton, Hulen & Albert, 2004 * '' Sternopygus dariensis'' Meek & Hildebrand 1916 * '' Sternopygus macrurus'' (Bloc ...

Richard Peter Vari
Richard is a male given name. It originates, via Old French, from Old Frankish and is a compound of the words descending from Proto-Germanic ''*rīk-'' 'ruler, leader, king' and ''*hardu-'' 'strong, brave, hardy', and it therefore means 'strong in rule'. Nicknames include "Richie", "Dick", "Dickon", " Dickie", "Rich", "Rick", "Rico", "Ricky", and more. Richard is a common English, German and French male name. It's also used in many more languages, particularly Germanic, such as Norwegian, Danish, Swedish, Icelandic, and Dutch, as well as other languages including Irish, Scottish, Welsh and Finnish. Richard is cognate with variants of the name in other European languages, such as the Swedish "Rickard", the Catalan "Ricard" and the Italian "Riccardo", among others (see comprehensive variant list below).

Polyphyletic
A polyphyletic group is an assemblage of organisms or other evolving elements that is of mixed evolutionary origin. The term is often applied to groups that share similar features known as homoplasies, which are explained as a result of convergent evolution. The arrangement of the members of a polyphyletic group is called a polyphyly .. ource for pronunciation./ref> It is contrasted with monophyly and paraphyly. For example, the biological characteristic of warm-bloodedness evolved separately in the ancestors of mammals and the ancestors of birds; "warm-blooded animals" is therefore a polyphyletic grouping. Other examples of polyphyletic groups are algae, C4 photosynthetic plants, and edentates. Many taxonomists aim to avoid homoplasies in grouping taxa together, with a goal to identify and eliminate groups that are found to be polyphyletic. This is often the stimulus for major revisions of the classification schemes. Researchers concerned more with ecology than with systema ...
