Mormyrops is a genus of African mormyrids — the weakly electric "elephantfishes" — distributed across river systems of central and equatorial Africa, with atlas records spanning the Democratic Republic of the Congo, the Republic of the Congo, Cameroon, Angola, the Central African Republic, Gabon, Ethiopia and Somalia. Like other mormyrids, they carry an electric organ near the tail that generates a weak field used for electrolocation and communication in dark or turbid water, an elongate body, and — as in the family generally — a brain-to-body mass ratio unusually large for a fish, comparable to some birds and mammals, driven by the neural processing electroreception demands. Unlike the short-snouted "elephantnose" mormyrids, most Mormyrops have a comparatively blunt, unadorned head rather than a trunk-like chin organ.
The genus spans an enormous size range for a single group of mormyrids, from modestly sized stream species up to the Cornish jack, M. anguilloides, which can reach around 59 in and ranks among the largest mormyrids known. Mormyrops are mostly nocturnal, poor-sighted, and navigate largely by electric sense, which makes them fascinating research subjects but demanding, specialist aquarium fish — few outlets stock them, and the trade that exists is built around size, electrogenic sensitivity to tank equipment and territorial behaviour rather than mass appeal. Most assessed species are Least Concern, with a handful Data Deficient, suggesting the genus is not under acute pressure but is also not thoroughly surveyed.
