Cornish jack

The Cornish jack, Mormyrops anguilloides, is a species of weakly electric fish in the family Mormyridae, native to quiet waters in much of Sub-Saharan Africa. The largest species in its family, the Cornish jack is a nocturnal group hunter of smaller fishes, using electricity to locate its prey and communicate with other members of its group. It is a commercial game fish valued for its size and taste. The common name "Cornish jack" likely originated from European settlers, who thought that this fish resembled the European pike, whose young is known as a "jack" in some parts of England. It is also known as "African carp", a name that is used for several other species.
