The tucan fish (Chalceus erythrurus),[1][2] also called the yellowfin chalceus,[3][4] 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
[edit]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.[5] In terms of size, it reaches 21.4 cm SL.[1] This makes it one of the larger members of the genus Chalceus, outsized only by the pinktail chalceus.
Etymology
[edit]The name "tucan fish" directly translates to "toucan fish", as "tucán" means toucan in Spanish.[6] 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.[7]
The genus name Chalceus is Greek, and means brass or copper.[1] The specific name erythrurus also originates in Greek, with "eruthros" meaning red and "ouros" meaning tail in reference to its caudal fin usually being reddish.[8]
Taxonomy
[edit]Upon being described by Edward Drinker Cope in the year 1870, the tucan fish was placed in the new genus Plethodectes with the full name Plethodectes erythrurus.[9] However, Cope switched it over to the genus Chalceus in the year 1872.[10]
It was briefly classified as Chalceus macrolepidotus iquitensis, a subspecies of the pinktail chalceus C. macrolepidotus, by Shoji Nakashima in 1941.[11] Henry Watson Fowler described it as Pellegrinina heterolepis in 1907, but Jacques Géry proved it to be a member of the Chalceus genus in 1977.[12][13]
The name Chalceus erythrurus was once mistakenly applied to C. macrolepidotus, and they are sometimes confused with one another.[14] They can be told apart because of the tucan fish's bright-yellow ventral fins, as well as a few other coloration patterns.[5]
Habitat
[edit]The tucan fish can be found in the Amazon and Solimões rivers, and its habitat extends into Peru by way of the Ucayali river.[1][13]
Diet and behavior
[edit]Like others in the genus Chalceus, the tucan fish is primarily a carnivore, targeting aquatic invertebrates (such as insects and crustaceans).[15] It is known to be somewhat skittish, and may jump out of the water on occasion.[3]
