Iguanodectes
''Iguanodectes'' is a genus of freshwater fish found in tropical South America, with eight currently described species. They are all small tetras, none longer than 5 inches, and often have attractive silvery or striped scales, which makes them a target for the ornamental fish industry. Alongside the genus ''Piabucus'', it is in the subfamily Iguanodectinae, which in turn is in the family Iguanodectidae. The genus ''Bryconops'', which is also in Iguanodectidae, makes up a sister clade to Iguanodectinae. Description Members of ''Iguanodectes'' are relatively slender, shaped somewhat like minnows; ichthyologists Carl H. Eigenmann and James Erwin Böhlke both compared them to smelt in general body composition. The largest (''Iguanodectes variatus'') reaches 10.3 cm (4.1 in) at a maximum in SL, and the smallest (''Iguanodectes gracilis'') 4.6 cm (1.6 in). This size makes them relatively easy to keep in captivity, and so several species of ''Iguanodectes'' - as with the whole subfamil ...

Iguanodectes Spilurus
''Iguanodectes spilurus'', the green-line lizard tetra, is a small characiform fish from the rivers of South America. It is not a well-studied species, but research is available, including data from hobbyists that keep it as an ornamental fish. It has a distinct lateral stripe of reflective-green scales, and lacks any red markings therein; red is common in congeners' lateral stripes (and is thus a differentiating feature). For a time, researchers had uncertainties regarding the taxonomic status of ''I. spilurus''. It was originally named as a member of sister genus ''Piabucus'', and then was described with the name ''I. tenuis''. However, its modern placement as a member of ''Iguanodectes'' with specific name ''spilurus'' is generally accepted by the scientific community. Description ''Iguanodectes spilurus'' is a small fish, reaching a maximum of 10.2 cm (4.0 in) in standard length (SL).

Iguanodectes Adujai
''Iguanodectes adujai'' is a species of freshwater fish that inhabits the rivers of South America. It largely prefers slow-moving blackwater habitats, though it has a slender body that suggests a further affinity for flowing water. It has a distinct lateral stripe in two horizontal sections, with bright-red at the top and yellow at the bottom. Though rare, it is seen in the aquarium trade, and is sometimes captured from the wild for collection or sale. ''I. adujai'' is sometimes sold in the same stock as congener ''I. geisleri'', due to a markedly similar appearance. Description ''Iguanodectes adujai'' is a small tetra with a slender build, reaching a maximum of 6.2 cm (2.4 in) standard length (SL). The general body shape has been described as similar to a smelt or minnow, something the genus ''Iguanodectes'' shares with sister genus ''Piabucus''."THE FISH FAMILIES".

Iguanodectinae
Iguanodectinae is a subfamily of small freshwater fish in the family Iguanodectidae. They are most prominently found in the Amazon river basin and its major tributaries, but they are also known from the Tocantins, Orinoco, and Paraguay rivers. It has two genera, ''Piabucus'' and ''Iguanodectes''. Some species in the subfamily are taken from the wild for aquariums, like the red- and green-line lizard tetras (''Iguanodectes geisleri'' and ''Iguanodectes spilurus'', respectively). There is minor, but ongoing, debate regarding its taxonomy. Description Members of Iguanodectinae are generally fairly small, none more than 13 cm in length. Members of ''Piabucus'' are slightly larger than members of ''Iguanodectes'', reaching a maximum of 12.9 cm (5.1 in), while members of ''Iguanodectes'' only reach 10.3 cm (4.1 in). They are slender and rather elongate in body shape, comparable to minnows; ichthyologist Carl H. Eigenmann, who named the subfamily, likened them to smelt. Their scales ...

Iguanodectes Geisleri
''Iguanodectes geisleri'', the red-line lizard tetra, is a species of freshwater fish from South America. It is a small species, largely herbivorous with some omnivorous traits, that prefers to live in schools and is partial to shallow waters, especially in blackwater habitats. Some aspects of its body plan are unique amongst its genus, including the position and length of the anal fin. Much of ''I. geisleri's'' behavior is known from observation in aquaria, but the middlingly-limited research in wild settings lines up with what fish keepers have noted. Though taken from the wild for export to various countries, ''I. geisleri'' - and members of ''Iguanodectes'' as a whole - are not sought out often enough for excessive capture to be of any concern. Description ''Iguanodectes geisleri'' is a small fish, reaching a maximum of 5.5 cm (2.2 in) standard length (SL). It has a lateral stripe that is divided horizontally into three colors - red at the top, then yellow-green, then bla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iguanodectes Gracilis
''Iguanodectes gracilis'' is a small species of freshwater fish from South America. It is known solely from the Rio Negro river system, which restricts its range only to Brazil. The name "gracilis" is in reference to a slender body shape, alongside the diminutive nature of ''I. gracilis'' - it is the smallest member of the genus ''Iguanodectes''. Granted species status in 1993, ''I. gracilis'' is one of the more recent additions to the genus ''Iguanodectes''. The publication that described it also described congeners ''I. variatus'' and ''I. polylepis'', both of which are generally more well-studied. Description ''Iguanodectes gracilis'' is a small species, reaching a maximum of 4.6 cm (1.8 in) standard length (SL). As with all Iguanodectinae, ''I. gracilis'' has a compressed, elongate body, comparable to the general shape of a smelt or minnow. When compared to congeners, however, it is slightly more slender, and is the smallest of the genus. (The largest is ''Iguanodectes v ...

Iguanodectes Polylepis
''Iguanodectes polylepis'' is a species of freshwater fish from the rivers of South America. Its range is restricted to Brazil, where it inhabits the Madeira and Purus river basins. It is one of the larger members of the genus, but remains generally small, only a little over a quarter-foot long. ''Iguanodectes polylepis'' was named in the same paper that named congeners ''I. gracilis'' and ''I. variatus''. None of the three species are particularly well-studied, though ''I. variatus'' is more well-known than the other two due to its presence in aquaria, albeit sparse. Description ''Iguanodectes polylepis'' is a small fish, measuring a maximum of 8.4 cm (3.3 in) standard length (SL). Nonetheless, it is somewhat large for a species of ''Iguanodectes'', and has the greatest number of lateral line scales therein, 76–81.Géry, J. 1993.Description de trois espèces nouvelles du genre Iguanodectes (Pisces, Characiformes, Characidae), avec quelques données récentes sur ...

Iguanodectes Variatus
''Iguanodectes variatus'' is a small freshwater fish, described from the rivers of South America in 1993. It has a minor presence in the aquarium trade, but lacks the popularity that would make excessive wild capture a legitimate threat. That being said, the threats facing South American aquatic environments are of ongoing concern for the associated biodiversity. Still, ''I. variatus'' has been recorded from various rivers and has shown general adaptability to its environment, which speaks to a high survivability. Description ''Iguanodectes variatus'' reaches a maximum of 10.3 cm (4.1 in) standard length (SL). As with the rest of its genus, its base scale color ranges from silver to silvery-yellow (more often the former), but it has characteristic mottling on its sides in light-brown. The top of the snout is also colored brownish, which can help distinguish it from similar-looking congeners,Géry, J. 1993.Description de trois espèces nouvelles du genre Iguanodectes (Pisces, C ...

Iguanodectes Purusii
''Iguanodectes purusii'' is a small freshwater fish from the rivers of South America. It is largely herbivorous, and prefers to live in schools. The name "purusii" originates from the species' type locality, the Purus river basin of Brazil, with a range that also extends into Peru. Furthermore, it has been documented from the Amazon, Madeira, Guaporé, and Pastaza rivers, but specific study of its ecology is otherwise lacking. Description ''Iguanodectes purusii'' is a small fish, reaching a maximum of 7.5 cm (2.9 in) standard length (SL). ''Iguanodectes'' as a genus is generally shallow-chested and narrow-bodied, with short pectoral fins, and ''I. purusii'' is no exception to this. The anal-fin origin is slightly posterior to the middle of the body, the dorsal fin the same, and the fins are largely hyaline (clear). Many members of ''Iguanodectes'' have a base scale color that is yellow to yellowish-silver, but ''I. purusii'' more frequently demonstrates plain silver; nonethe ...

Iguanodectidae
Iguanodectidae is a family of freshwater fish in the order Characiformes that lives in South America. It is home to the subfamily Iguanodectinae (Eigenmann, 1909) and the monotypic ''Bryconops'' clade. Several species in the family, such as the green line lizard tetra (''Iguanodectes spilurus''), the tailspot tetra (''Bryconops caudomaculatus''), and the orangefin tetra (''Bryconops affinis''), are sometimes taken as aquarium fish. Description Iguanodectids are generally small, and are brightly colored or reflective, making them moderately-popular ornamental fish. They range from 3.1 cm to 15 cm SL (standard length). They are rather narrow in shape, somewhat resembling minnows; ichthyologist Carl H. Eigenmann compared them to smelt. Habitat Iguanodectids are found in South America, spread all across the northern half of the continent. Though they primarily inhabit freshwater, Iguanodectid fishes are known to tolerate brackish water as well. Habitat destruction, ...

Iguanodectes Rachovii
''Iguanodectes rachovii'' is a species of freshwater fish that inhabits the rivers of the Amazon basin. It largely consumes insects, though it will eat plants if given the opportunity, and has a peaceful disposition, able to live alongside various other species. It is often found in groups of 3 to 30 specimens, lingering at the edges of streams near the surface of the water. Given its appealing coloration, ''I. rachovii'' has a minor presence in aquarium settings, but is not often taken from the wild for export. Arthur Rachow, an aquarist from Germany, brought specimens of ''I. rachovii'' to the attention of British ichthyologist Charles Tate Regan, thereby assisting in the discovery and description of a new species. Subsequently, the fish was named in his honor. Description ''Iguanodectes rachovii'' is a small fish, reaching a maximum of 6.2 cm (2.4 in) standard length (SL). It has an elongate body shape, and is generally quite slender, as is the case in all ''Iguanodectes''; ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Piabucus
''Piabucus'' is a genus of freshwater tetras in the family Iguanodectidae. All three species are found in South America, largely the Amazon and its major tributaries. None of them are longer than half a foot long, with the largest reaching a maximum size of 12.9 cm (5.0 in), and they are slender, with relatively deep chests and long pectoral fins. Their scales are pale or silvery, with lateral lines that stand out. At least one species, ''Piabucus dentatus'', is known to be collected for the aquarium industry. All three species are sometimes given the collective name "chin tetras" by sellers, in reference to markings on the lower jaw. However, none of the species are considered endangered, so capture of wild specimens is not an immediate threat to population numbers. As well as this, collection is not happening at a high enough rate to be of any concern. ''Piabucus'' has a close relative in the genus ''Iguanodectes''. The two are paired in the subfamily Iguanodectinae, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
