The monkeyface prickleback (Cebidichthys violaceus), also commonly known as the monkeyface eel, is a species of prickleback native to the Pacific coast of North America. Despite being commonly called an eel due to its body shape, it does not fall into the fish order Anguilliformes with true eels, but the Perciformes along with nearly half of all bony fishes.
