Characterized by mottled color and tooth bands with a separated inner series. The only other species within its range with these characters is Anguilla marmorata, but that species has a longer dorsal fin (Ref. 9828).
Body shape (shape guide): eel-like.
Adults occur in coastal lagoons, rivers, streams, lakes, swamps and farm dams, but prefer riverine habitats (Ref. 26509, 44894). Usually found in deep waters of reservoirs well away from the shore. Mature adults undertake annual spawning migrations to oceanic waters (Ref. 44894). Mainly nocturnal feeders. They feed on crustaceans, mollusks, aquatic and terrestrial insects, fish including elvers and native trout. Maximum size for female longfin eel taken from Ref. 6390. A reasonably good angling fish which may grow to 22 kilograms (Ref. 44894).
