The round-headed Nilhechte ( Pollimyrus ) are a genus of African freshwater fish from the family of the Nilhechte (Mormyridae), which is widespread with 18 species in Africa south of the Sahara.
features
Round-headed Nile Pikes are small to medium-sized Nile Pikes with short or moderately elongated bodies, rounded heads and short snouts without swelling of the chin. The fish are 6 to 20 cm long. The anterior and posterior nostrils are apart, the posterior near the eyes. By the position of the nostrils one can distinguish the round-headed Nilhechte from the stomatorhinus and petrocephalus species, which have a similar body shape. The lower jaw of the round-headed Nilhechte has fewer than ten teeth. The beginning of the dorsal fin is just behind the approach of the anal fin. Like all Nilhechte, Pollimyrus species are capable of electrical communication and electrical orientation .
