Description

The brill is a large, left-eyed flatfish of the family Scophthalmidae reaching about 75 cm. Like the closely related turbot it lies on its right side, so both eyes are on the left; the brill, however, is rounder and more slender, lacks the bony tubercles of the turbot and has smooth scales and fringed front dorsal-fin rays. The brownish mottled upper side adapts to the bottom for camouflage. The species lives on sand and gravel bottoms of the north-eastern Atlantic, the North Sea and the Mediterranean. As an ambush hunter it lies buried and seizes small fish, shrimps and crustaceans. The brill has fine, prized flesh and is an important sport and food fish.
