The longfin snake-eel (Pisodonophis cancrivorus) is an eel in the family Ophichthidae (worm/snake eels). It was described by John Richardson in 1848. It has a Dorsal fin beginning above its pectoral fin with a snake-like upper body which is cylindrical, but compressed only along its extreme tail tip. It also has a tubular nostril in front and a nostril along the lower edge of the lip in back. Colors range from grey to black to brown. Large longfin snake-eels have wrinkled skin.
