The narrow, rearward-tapering body has a rounded, hook-shaped snout; the dorsal, tail and anal fins merge into a continuous fringe. Both eyes lie close together on the left side.

On the bottom it searches, mainly at night, for worms, small crustaceans and molluscs. With its fine flesh it is a valued commercial fish in West Africa, heavily landed by coastal fisheries.
