![]() If a flatfish is caught from a pier in Iceland, it’s probably a dab. Dab is a shallow water species and is very common from just below the tide mark to about 40 m depth. The easiest way to distinguish between the two, however, is that the dab’s scales feel like sandpaper if rubbed from tail to head whereas plaice are rather smooth. Juveniles inhabit inshore waters on sandy or muddy bottoms and adults live in deeper waters except during spawning.ĭab( Limanda limanda) is similar to the plaice in appearance, but it does not have the red spots and tends to be closer to brown than green. European plaice are common around Iceland. The underside is white, sometimes with brown or grey patches. The plaice is a medium-sized flatfish with a dark green upper surface featuring red spots. The European plaice( Pleuronectes platessa) was long the most commercially important flatfish on Iceland’s northern coast, but in recent years that distinction has been taken by the Greenland halibut. Thirteen species of flatfish have been found in Icelandic waters and most have been found in Northern Iceland. The halibuts are examples of flatfish that specialize in eating fish. ![]() Most flatfish eat primarily small invertebrates, but many also hunt young fish as well. Flatfish are most common in areas where the bottom is flat and composed of soft sediment, where they can avoid predators or hide themselves to wait in ambush for prey. ![]() This is an adaptation to life on the seafloor. The main characteristic of flatfish is that they are flat, as the name indicates.
