Description
The African Brown Knifefish is a nocturnal, elongated fish native to various river systems in West and Central Africa. It lacks a dorsal fin and uses its long anal fin for propulsion, often swimming with a unique undulating motion. This species is known for its electroreception, which it uses to navigate and locate prey in murky waters.
