The slender snipe eel (Nemichthys scolopaceus), also known as the deep sea duck, is a fish that can weigh only a few ounces, yet reach 5 feet or 1.5 m in length.

Features include a bird-like beak with curving tips, covered with tiny hooked teeth, which they use to sweep through the water to catch shrimp and other crustaceans.

Many specimens found in museums were spat up from larger fish that were caught in trawls.

Adults can be found from the surface to 4,000 meters in the North Atlantic, and perform diurnal migration.
