Description

The bigtooth elephantfish is an African weakly electric fish of the family Mormyridae from the Congo basin. The species has an elongate, laterally compressed body with the dorsal and anal fins set far back, characteristic of this family, and, as the name indicates, relatively large teeth. Like all elephantfishes it generates a weak electric field with an organ in the tail base to navigate in turbid water, locate prey and communicate. It searches the bottom for insect larvae and small invertebrates. The species is harmless to humans.
