Nettastomatidae, the duckbill eels or witch eels are a family of eels. The name is from νῆττα (Greek: duck) and στόμα (Greek: mouth).
Duckbill eels are found along the continental slopes of tropical and temperate oceans worldwide. They are bottom-dwelling fish, feeding on invertebrates and smaller fish.[1] They are slender eels, up to 125 centimetres (4.10 ft) in length, with narrow heads and large, toothy, mouths. Most species lack pectoral fins.
