Description

The pelican flounder is a remarkable deep-water flatfish of the family Bothidae (lefteye flounders) reaching about 40 cm. Both eyes lie on the left side. The body is thin, pale and almost translucent, but the head bears an extraordinarily large mouth with a huge, expandable throat pouch reminiscent of a pelican's - hence the name. With it the fish scoops up small fish and crustaceans on the bottom. The species lives on soft bottoms of the continental slope of warm and temperate seas worldwide. Because of its deep lifestyle it is only rarely seen and has no fishery value.
