Compsaraia samueli, the pelican knifefish, is a species of apteronotid knifefish from the western Amazon basin of Brazil and Peru. Like other gymnotiform knifefish, it is an electric fish. It exhibits pronounced sexual dimorphism in which mature males develop extremely elongated snouts and jaws. This phenotype is found in several other apteronotid species and is used in agonistic jaw-locking behaviors between males.
