Language English Photo: Biodôme OngletsDescriptionDistinguishing featuresThe winter flounder is an oblong laterally compressed flatfish. Its two eyes are set on the right side of its head, or the top side of its body. Its body is reddish brown to blackish on the top side and cream-coloured underneath. Its long dorsal and anal fins fan out around its body. ReproductionSpawning occurs in shallow water, in late winter and spring. A female produces 500,000 eggs on average, potentially up to about 2.5 million. DietThese fish eat a variety of invertebrates, including amphipods, isopods, marine worms, snails, soft-shelled clams and capelin eggs. They feed during the day, eating more in summer than winter. PredatorsThe young are preyed upon by great blue herons and cormorants. In winter, in deep water, the adults are often attacked by sea ravens, spiny dogfish and monkfish. Seals are also major predators of winter flounder. In summer, they are attacked by ospreys. HabitatThey frequent fairly shallow water, at depths of 1.8 to 36 m, over mud and sand bottoms. Ecology, behaviourWinter flounder are well adapted to life on the sea bottom. With their flattened bodies and colouring, which varies with their environment, they are able to hide on the bottom. The adults swim and spend their lives lying on the left side of their flattened bodies. The larvae have a different shape from the adults. They swim like most other fish, with their bellies facing downward.
