FLOUNDER

The flounder (Pleuronectes) is one of the flat-fishes of the family Pleuronectidae. The common flounder (Pleuronectes flesus) is found in the sea and near the mouths of large rivers around the British coast. Flounders have been successfully transferred to fresh-water ponds. They feed upon Crustacea, worms, and small fishes, and are much used as food. The Argus-flounder is the Pleuroncetes argus, a native of the American seas.
