Chalceidae
Chalceidae, the tucanfishes, is a family of freshwater fish first described by Henry Weed Fowler in the year 1958. It is a monotypic family, home only to the genus ''incertae sedis'' ''Chalceus''. All members of the family inhabit areas of northern South America, including the Amazon River and various tributaries. Classification Chalceidae is in the order Characiformes. The genus ''Chalceus'' used to be placed in the family Characidae, and is still listed there by several sources (like GBIF and ITIS). Research since its original placement suggested movement into the family Chalceidae, based upon phylogenetic significance as a monophyletic group.Oliveira, C., Avelino, G.S., Abe, K.T., Mariguela, T.C., Benine, R.C., Orti, G., Vari, R.P., & Correa e Castro, R.M.

Chalceus
''Chalceus'' is a genus of fish that inhabits freshwater habitats in South America. Members can be found in the Amazon and Orinoco basins, as well as in the Guianas and various tributaries of the former. It is the sole representative of the family Chalceidae. Description Members of the genus ''Chalceus'' typically reach a length of 15–25 cm (6–10 in), but are up to about 30 cm (12 in). They have an elongated shape, and relatively large scales. Their fins are a variety of colors, most commonly red, yellow, or hyaline, with a red or pink tail being the most common. Classification ''Chalceus'' was previously classified as a member of the family Characidae, and is still listed there by some authorities (like GBIF and ITIS). However, recent phylogenetic and morphological analysis has prompted a move into the family Chalceidae, which is currently home only to the genus ''Chalceus'' (making it monotypic).Oliveira, C., Avelino, G.S., Abe, K.T., Mariguela, T.C., Benine, R.C., ...

Chalceus Erythrurus
The tucan fish (''Chalceus erythrurus''), also called the yellowfin chalceus, is a species of freshwater fish in the family Chalceidae. It is one of five species in the genus ''Chalceus'', and was the second species to be described therein. Description The tucan fish has a pale-silver body, with bright-yellow ventral fins (hence its other common name); the rest of its fins are some mixture of yellow and red, usually with a reddish tail fin. In terms of size, it reaches 21.4 cm SL. This makes it one of the larger members of the genus ''Chalceus'', outsized only by the pinktail chalceus. Etymology The name "tucan fish" directly translates to "toucan fish", as "tucán" means toucan in Spanish. All members of the family Chalceidae are sometimes referred to as tucanfishes, but ''C. erythrurus'' is the species to which it is most often applied. The genus name ''Chalceus'' is Greek, and means brass or copper. The specific name ''erythrurus'' also originates in Greek, with "eruthr ...

Chalceus Guaporensis
''Chalceus guaporensis'' is a species of freshwater fish in the family Chalceidae that inhabits northern South America. Alongside '' C. epakros'' and '' C. spilogyros'', it was added to the genus ''Chalceus'' in the year 2004. Description Visually, ''C. guaporensis'' is similar to other ''Chalceus'' species, with metallic scales and a vivid caudal fin (often reddish or pinkish). It is also within the average size range of the genus, reaching 17.4 cm SL. It has a darker stripe down each side that reaches the caudal peduncle; ''C. guaporensis'' and ''C. epakros'' are the only two members of the genus ''Chalceus'' to sport this lateral stripe, differentiating them from the other three. ''C. guaporensis'' also usually has humeral spots (a dark spot above each pectoral fin), but they are not as well-defined as those in ''C. spilogyros'' or ''C. epakros.'' ''C. guaporensis'' and ''C. epakros'' share a more elongated and pointed snout than other ''Chalceus'' species, but it is more pr ...

Chalceus Epakros
''Chalceus epakros'' is a species of freshwater fish in the family Chalceidae, found in northern South America. It is a fairly recent addition to its genus, alongside the species '' C. guaporensis'' and '' C. spilogyros''. Description ''Chalceus epakros'' bears visual similarities to other members of the genus ''Chalceus'', like metallic scales and a vivid red or pink caudal fin, though several differences help separate it from its congeners. It has a thin stripe laterally that reaches the caudal peduncle, as well as a longer and more pointed snout. It may occasionally bear humeral spots (a spot above each pectoral fin), but they are rather indistinct, especially compared to the humeral spots of '' C. spilogyros''. Its fins are a mixture of hyaline and reddish-pink, as opposed to the bright-yellow pelvic fins of '' C. erythrurus''. ''Chalceus erythrurus'' and ''C. macrolepidotus'' may occasionally bear a similar lateral stripe to ''C. epakros'', but theirs are broader and more ...

Chalceus Macrolepidotus
The pinktail chalceus (''Chalceus macrolepidotus''),U.S. Fish and Wildlife Service. Pinktail Chalceus (Chalceus macrolepidotus) Ecological Risk Screening Summary'. 2018. also called the pinktail characin, is a species of freshwater fish of the family Chalceidae found in South America. It is one of five fish in the genus ''Chalceus'', and is the type species of the genus. Description The pinktail chalceus is a small, light-colored freshwater fish with a tail that is usually dark red to pink and is much more intensely colored than the rest of the animal. It has large, noticeable scales and reaches 24.5 cm SL, making it the largest known member of ''Chalceus''. The smallest is ''Chalceus epakros''. ''Chalceus epakros'', before being classified, was regularly misidentified as either the pinktail chalceus or the yellowfin chalceus (''Chalceus erythrurus''). ''C. epakros'' and the pinktail can be told apart because the pinktail is uniform silvery in color, whereas ''C. epakros'' has ...

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] |
Characidae
Characidae, the characids or characins is a family of freshwater subtropical and tropical fish, belonging to the order Characiformes. The name "characins" is the historical one, but scientists today tend to prefer "characids" to reflect their status as a by and large monophyletic group at family rank. To arrive there, this family has undergone much systematic and taxonomic change. Among those fishes that remain in the Characidae for the time being are the tetras, comprising the very similar genera ''Hemigrammus'' and ''Hyphessobrycon'', as well as a few related forms such as the cave and neon tetras. Fish of this family are important as food and also include popular aquarium fish species. These fish vary in length, though many are less than . One of the smallest species, ''Hyphessobrycon roseus'', grows to a maximum length of 1.9 cm. These fish inhabit a wide range and a variety of habitats. They originate in the Americas, ranging from southwestern Texas and Mexico through ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chalceus Spilogyros
''Chalceus spilogyros'', sometimes misspelled as ''Chalceus spilogyrus'', is a species of freshwater fish in the family Chalceidae that inhabits northern South America. It is a relatively new member of the genus ''Chalceus'', along with '' C. epakros'' and '' C. guaporensis''. Description ''Chalceus spilogyros'' bears many visual similarities to other ''Chalceus'' species, including metallic scales and a vividly-colored caudal fin (usually red or pink); the rest of its fins are hyaline. Its scales also bear a reticulate (net-like) pattern, which is often uniform across the whole body. It has a comparatively rounded snout, and lacks the thin lateral stripe of ''C. guaporensis'' and ''C. epakros'', but it bears a small-yet-distinct humeral patch (a patch above each of the pectoral fins) to differentiate it from ''C. macrolepidotus'' and ''C. erythrurus''. Its hyaline fins further separate it from ''C. erythrurus'', whose pelvic fins are bright yellow. ''C. erythrurus'' may bear ...

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 ...
