Description

The slimy swamp eel is a swamp eel (Synbranchidae) from shallow fresh and brackish water of northern Australia and New Guinea. The species grows to about 40 cm and has an elongate, eel-like, grey-brown body without pectoral fins and with a smooth, slimy skin and a single gill slit under the throat. With an air-breathing organ it can live in oxygen-poor water and even moist mud. As a nocturnal bottom-dweller it snaps at small invertebrates, worms and small fish. The fish is harmless to humans.
