Boulengerella cuiveri, commonly known as the bicuda, is a species of pike-characin in the family Ctenoluciidae.

The fish is named in honor of French naturalist and zoologist Georges Cuvier (1769–1832), because he was first to accurately diagnose the family Salmones, which at that time included all characiform fishes.

[4] Boulengerella cuiveri is a freshwater fish native to the Amazon region.

Furthermore, it is can also be found in the Essequibo River in Guyana and French Guiana.

It can be found on the surface of areas with rapidly flowing water, usually behind obstacles such as fallen logs or rocks.
