Description

The spotted-tail duckbill is a slender bottom fish of the family Percophidae (duckbills) reaching about 24 cm. The flattened head extends into a broad, flattened, duck-bill-like snout, with large eyes directed upward and forward - features suited to a life lying on soft bottoms, watching for prey; a dark spot sits on the tail. The species lives on soft bottoms of the deeper continental shelf and upper slope of the Indian and western Pacific Oceans. On the bottom it ambushes small crustaceans, shrimps and small fish. Because of its deep lifestyle and small size it has no fishery value and is only rarely seen.
