Mormyroidei

Mormyroidei is a suborder of African freshwater fish, commonly known as mormyrids or elephant-snout fishes. These fish are characterized by their soft-rayed bodies, abdominal pelvic fins, forked tails, small mouths and eyes, and restricted gill openings. They possess proportionally large brains, indicating well-developed senses.1

A unique feature of mormyrids is the presence of mild electric organs in their tails, which generate a continuous electric field around the fish. This field acts as a sensory screen, helping them navigate and detect prey, predators, and obstacles in their often murky habitats. Most mormyrids feed on small prey, aquatic vegetation, or organic debris. Some species, like the elephant-snout fish (Gnathonemus), have a distinctive long, trunklike snout.12
