The solitary duckbill eel[1] (Nettastoma solitarium) is an eel in the family Nettastomatidae (duckbill/witch eels).[2] It was described by Peter H. J. Castle and David G. Smith in 1981.[3] It is a marine, deep-water-dwelling eel which is known from the Indo-Western Pacific, including Kyushu–Palau Ridge, the Philippines, Australia, and the Hawaiian Islands. It is known to dwell at a depth range of 415 to 610 metres (1,362 to 2,001 ft). Males can reach a maximum total length of 46.5 centimetres (18.3 in).[2]

The species epithet "solitarium", meaning "solitary" in Latin, refers to the species' wide and isolated distribution in the Pacific.[2]
