生態學
海洋; 淡水; 半鹹淡水 居於水底的; 降海洄游 (Ref. 51243). 熱帶; 22°N - 27°S
Indo-Pacific: widespread in the tropical Indian Ocean and western Pacific. Known in Australia only from streams in the Kimberley regions of northern western Australia. Africa: widespread but relatively uncommon along east and southeast African coast and Madagascar (Ref. 7248, 52193). Mozambique; Lower Zambezi River (Ref. 39494). Most easily confused with Anguilla obscura and the surest way to distinguish them is by the count of vertebrae (Ref. 9828).
印度-太平洋: 在熱帶的印度洋與西太平洋中廣泛分佈。 在澳洲在澳洲西北部的慶伯利區域中只從溪流。 非洲: 廣泛分佈但是相當稀有的沿著東方與非洲海岸東南部與馬達加斯加.(參考文獻 7248) 莫三比克; 尚比西河下游河.(參考文獻 39494) 最容易與 安圭拉 obscura 與最可靠的方法互相混淆區別他們是藉著脊椎骨的數量.(參考文獻 9828)

Migratory species which breeds in the ocean (Ref. 52331, 79840). Lives in fresh water areas as an adult, in estuaries and seas as young (Ref. 12693). Descends to the sea to spawn. Inhabits freshwater streams and pools, preferring marshy habitats (Ref. 41236). Found in rivers and creeks, commonly over rock bottoms and in deeper pools. Seldom occurs in large rivers (Ref. 6028). Restricted to lowland (coastal) reaches of river systems (Ref. 7248). Feeds on small fishes, crustaceans and mollusks. Reported to breed east of Madagascar; the south equatorial current probably carries the eel larvae and elvers towards the east coast of Africa where local coastal currents guide the elvers to suitable rivers which they invade and they stay there until sexually mature, when they return to their breeding grounds (Ref. 13337). Caught with various types of nets. Sometimes used in the aquarium trade (Ref. 6028).
在海洋中繁殖的迴游種.(參考文獻 52331) 作為一個成魚生活在淡水區域, 在河口與海洋中當幼魚時.(參考文獻 12693) 下降到海洋產卵。 棲息於淡水溪流與水池, 偏愛多沼地的棲息地。 (參考文獻 41236) 發現於河與小溪了, 通常在石質底部之上與在較深的水池中。 很少出現於大河中。 (參考文獻 6028) 侷限於低地 (海岸的) 河流域的範圍了。 (參考文獻 7248) 吃小魚，甲殼動物與軟體動物。 報告繁殖馬達加斯加東方; 赤道南方的洋流可能運送鰻魚仔魚與鰻苗到非洲東岸在那裡近岸洋流引導對適當的河他們侵入那一個的鰻苗，而且他們在那裡停留直到性成熟, 當他們回到他們的繁殖場的時候.(參考文獻 13337) 用各種不同類型的網捕獲了。 有時被用於水族貿易。 (參考文獻 6028)
