The speckled longfin eel, Australian long-finned eel or marbled eel (Anguilla reinhardtii) is one of 15 species of eel in the family Anguillidae. It has a long snake-like cylindrical body with its dorsal, tail and anal fins joined to form one long fin. The dorsal fin also often extends farther than the anal fin. It usually has a brownish green or olive green back and sides with small darker spots or blotches all over its body. Its underside is paler. [2] It has a small gill opening on each side of its wide head, with thick lips. It is Australia's largest freshwater eel, and the female usually grows much larger than the male. [2] [3] It is also known as the spotted eel.
Long-finned eels can grow up to a maximum of 1.6 m (5 ft 3 in) and 22 kg (49 lb), although they generally grow to 1 m (3 ft 3 in)) for females while males are much smaller at 650 mm (2 ft 2 in) and 600 g (1.3 lb). [4] Landlocked eels have been reported to grow to 3 m (9.8 ft). [3]
The long-finned eel is a native of New Guinea, eastern Australia (including Tasmania), Lord Howe Island, and New Caledonia. [2] It can be found in many freshwater areas, including creeks, streams, rivers, swamps, dams, lagoons, and lakes although generally more often in rivers than lakes. [3]
Like other Anguilla species, the eel lives predominantly in freshwater rivers and streams, but is born in deep waters of the ocean. Each species has its own spawning grounds; spawn use ocean currents to return to their adult species range. The long-finned eel spawns in the Western arm of the Southern Equatorial Current, [5] which carries spawn to the eastern coast of Australia. This species is panmictic, spawning throughout the year. [6]
A carnivorous species, the speckled longfin eel eats an assortment of aquatic vertebrates, such as fish, turtles, and small birds. [7]
