Description

De Silva's swamp eel is a swamp eel (Synbranchidae) from swamps, rice fields and slow-flowing fresh water of Sri Lanka in South Asia. The species grows to about 30 cm and has a snake-like, scaleless, brown body without pectoral and pelvic fins and with gill slits fused into a single opening. In oxygen-poor water it can gulp air and survive in moist mud during drought. As a nocturnal hunter it snaps at worms, insect larvae and small fish. The fish is harmless to humans.
