The blunt-jawed elephantnose, Gnathonemus tamandua, is an elephantfish in the genus Gnathonemus. Other names in English include worm-jawed mormyrid. It is found in murky waters in West Africa. The fish is brown or black with a long elephant-like snout and the mouth is located near the end of this probiscis. Its diet consist of worms, small fish, and insects.[citation needed]
In captivity are fairly hard to take care for because they need a narrow range of water temperatures, a large tank, and special food.[citation needed]
