生态学
海洋; 淡水; 半咸淡水 底中水层性; 降海洄游 (Ref. 9258); 深度上下限 0 - 3000 m (Ref. 86942). 亞熱帶的; 18°S - 47°S, 140°E - 168°E
Southwest Pacific: east coast of Australia and New Zealand, extending north to New Caledonia. Museum records from Fiji and Tahiti are doubtful. Australian and New Zealand forms sometimes recognized as subspecies. Most easily confused with Anguilla obscura and the surest way of distinguishing them is to count the vertebrae. Reported from Western and American Samoa (Ref. 592).
西南太平洋: 被向北延伸到新加勒多尼亞的澳洲東岸與紐西蘭。 博物館來自斐濟的紀錄，而且大溪地島是可疑的。 澳洲與紐西蘭的型有時被鑑定為亞種。 最容易互相混淆區分他們的 安圭拉 obscura 與最可靠的方法將計算脊椎骨。 記錄來自西薩摩亞與美屬薩摩亞了。 (參考文獻 592)

Maturity: Lm ? range ? - ? cm
Max length : 130 cm TL 雄鱼/尚未辨别雌雄; (Ref. 40637); 106.5 cm TL (female); common length : 45.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 9258); common length :65 cm TL (female); 最大体重: 7.5 kg (Ref. 40637); 最大年龄: 32 年 (Ref. 6390)
Occurs in streams, lakes and swamps. More likely inhabits slow flowing streams or still waters (Ref. 26509). Feeds on fishes, crustaceans, mollusks, worms, aquatic plants, and terrestrial and aquatic insects. This species does not breed outside its Pacific spawning ground. Migrates to the sea to breed (Ref. 9258). Maximum length for female eel taken from Ref. 6390. Migrating females in Lake Ellesmere (Canterbury, New Zealand) were reported to be in the range of 48.3 to 102.4 cm, larger than for males 33.8 to 55.4 cm (Ref. 44724). Despite its slimy appearance, its flesh is of excellent quality, considered a delicacy in many countries; meat suitable for smoking (Ref. 33839).
出现在溪流，湖与沼泽。 更或许居住于慢的流动溪流或静止的水域。 (参考文献 26509) 捕食鱼，甲壳动物，软件动物，蠕虫，水生植物与陆生与水生昆虫。 这种不在被产卵地面的它的太平洋的外边繁殖。 回游到海洋繁殖。 (参考文献 9258) 最大的母鱼体长鳗鱼取自了参考文献 6390. 不在乎它的黏滑外表，它的肉是有在许多国家中被认为是一个佳肴的优良品质的; 肉适合做烟熏。 (参考文献 33839)
