Description

Greshoff's spiny eel is an eel-like freshwater fish of the spiny eel family (Mastacembelidae) from the Congo basin in Central Africa. The species grows to about 33 cm and has a strongly elongate, snake-like body with a pointed, mobile snout and a row of short, separate spines before the soft dorsal fin, from which the family takes its name. It lives over rocky bottoms in rivers and lakes, including rapids, and likes to burrow. As a nocturnal bottom hunter it searches for worms, insect larvae and small invertebrates. The spines can prick, but the species is otherwise harmless to humans.
