In saltwater, flatfish live along continental shelves, including those off Canada’s Pacific and Atlantic coasts. Range and Habitatįlatfishes are found globally in saltwater, freshwater, and brackish environments. The fishes in the mostly North Americanįamily Pleuronectidae have mouths that are large and toothed, while other flatfishes, such as soles in European waters, have very small and highly specialized jaws. By comparison, flatfish in the family Cynoglossidae lack pectoral fins entirely. Some flatfishes, suchĪs those in the family Bothidae, have elaborate and ornate elongations of the fins on the sides of their body, known as pectoral fins. For example, some tropical species measure less than 5 cm long, while the Atlantic halibut reaches lengths of up to 2 m and weighs in excess of 300 kg. Otherwise, there is an incredible variation in size and shape among flatfishes. Flatfishes are also characterized by having a dorsal fin that extends onto the back part of their skull. Their other distinguishing feature is the presence of both eyes on the same side of their head. Flatfish are so-called because they are, indeed, flat.
