Description

The sailfin worm eel is a snake eel (Ophichthidae) from shallow sandy and coastal water of the western Atlantic. The species grows to about 40 cm and has a very slender, eel-like, pale body with a high, sail-like dorsal fin origin and a hard, pointed tail with which it burrows backwards into sand. As a nocturnal bottom-dweller it lies hidden by day and searches for small invertebrates and small fish at night. The fish is harmless to humans.
