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).

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).
