Derichthyidae (Longneck eels)
Etymology: Nessorhamphus: Greek, nessa, netta = duck + Greek, rhamphos = bill, peak (Ref. 45335).
Meio ambiente: milieu / Zona climática / intervalo de profundidade / faixa de distribuição
Ecologia
marinhas batipelágico; intervalo de profundidade 0 - 1800 m (Ref. 58018). Deep-water
Eastern Atlantic: France to Morocco; off the Cape, South Africa (Ref. 6592). Also known from temperate and subtropical latitudes of the western Atlantic, southwestern Indian, and southwest Pacific.
Tamanho / Peso / Idade
Maturidade: Lm ?  range ? - ? cm
Max length : 60.0 cm TL macho/indeterminado; (Ref. 123983)
Espinhos dorsais (total) : 0; Espinhos anais: 0. Dark brown in color (Ref. 6592). Snout long, depressed, and spatulate in form; lateral line distinct; pectoral fin long, subequal to snout; dorsal and anal fin rays abruptly become shorter near tip of tail and once again become longer, so it appears an independent caudal fin is present (Ref. 13608).
Body shape (shape guide): eel-like.
Mesopelagic (Ref. 5951). Feeds mainly on crustaceans.
