Flatfish belong to the order Pleuronectoformes. There are more than 500 species of flatfish. Flatfish live on and partly in the seabed, only the halibut swims higher up in the water column. Flatfish have an oblong, flat shape and their eyes on one side. The upper-side, the eye-side, of the flatfish has a camouflage colour and the underside is white. It may seem like flatfish swim on their belly, however, in fact, they are laying on their side. Flatfish larvae have a regular fish shape, with eyes on each side and a vertical swimming mode. After 6 weeks, one of the eyes migrates upwards, over the head to the other side. From now own, the flatfish swims with their eyes up and their blind side facing the seabed.
The best known flatfish species in the Netherlands are sole and plaice. Other flatfish species that occur in the North Sea are the common dab, halibut, turbot, brill, European flounder and lemon sole. Flatfish are caught with beam trawls, pulse trawls or demersal otter trawls.
Turbot is a large diamond-shaped flatfish that occurs from Norway to Morocco and in the Mediterranean and Black Seas. Turbot belongs to the larger flatfish species: this fish can grow to a length of 100 cm and weigh 25 kg. Their eyes, similar to brill and megrim, are on the dark green colored left side of the body. On that side they have no scales, but they do have bony nodules. The difference with brill is clear, because brill has a smooth skin with scales.
