Description

The duckbill oceanic eel is a snake-like deep-sea eel of the family Derichthyidae reaching about 60 cm. The slender, brownish to silvery body tapers backward and bears a continuous dorsal and anal fin; striking is the long, flattened snout resembling a duck's bill, which gives the species its name. It lives meso- to bathypelagically in the open water of tropical and temperate oceans worldwide, including the Atlantic. Unlike many eels it does not live on the bottom but hovers in the water column, where it hunts small fish and crustaceans. Like all true eels it develops through a transparent, leaf-shaped leptocephalus larva that drifts with the currents for a long time before transforming.
