Description

The Madeira swamp eel is a swamp eel (Synbranchidae) from slow-flowing and still fresh water of the Amazon basin in South America. The species grows to about 40 cm and has a snake-like, scaleless, brown body without pectoral and pelvic fins and with strongly reduced gill openings fused into a single slit under the throat. In oxygen-poor water it can gulp air and survive in moist mud during drought. As a nocturnal hunter it snaps at small fish, crustaceans and insect larvae. The fish is harmless to humans.
