FaunaFigures Fishes Black Ghost Knifefish


This figure is part of the fourth wave of three models I have had made specifically for the site, as Fauna Figures Fishes. As a fan of primitive and unusal fishes, I wanted to see more species available–so why not have some made!? This wave is of South American species!

These models are not meant as toys, although they are very durable (certainly not bath toys!). They are instead meant as display or diorama models, to help increase the visibility of some less common fish! Each piece is about 4″ long, made of a light-weight resin and painted by sculptor Brandon DeMoss specifically for Fauna Figures, so each one will be a unique individual!

Because every FaunaFigures Fish replica is a custom product and can be made to order, we do allow backorders. If we are out of stock, youcan order one and we will ship your order when everything has arrived. It can take two to three weeks for the FaunaFigures Fish models to be ready. If you have any concerns about timing, or special requests, please contact us prior to ordering.


The Black Ghost Knifefish Apteronotus albifrons represents a fairly modern group of fishes, with fossils of the order known from the Miocene. Overall, their fossils are poorly known due to their preferred tropical habitats–not much chance for fossils!

Ghost Knifefish are a large group of distinct freshwater fish from the rivers of South America. Their long, skinny bodies and single long anal fin make them highly maneuverable, able to swim backwards and forwards with ease. They are primarily nocturnal, and prefer to hide during the day–but the Black Ghost Knifefish and some of its kin are still popular aquarium fish. They really are fun to watch swirl back and forth while looking for food or just moving around.

They are also notable for how they ‘see’ the world–less with their eyes, and more with modified muscles that provide an electrical field around them! With these, they can find prey, avoid predators, and communicate with other knifefish. One knifefish relative is especially famous for this adaptation–the electric eel Electrophorous electricus is a giant knifefish relative, well known for its electrical output. While the Black Ghost Knifefish only uses weak electric impulses, the electric eel can sound out charges strong enough to kill prey or even a person!
