Quick Summary

The European flounder (Platichthys flesus) is a type of flatfish found in European marine and freshwater environments. These fish are morphogenetically unique; upon hatching, they are bilaterally symmetrical with an eye on each side. However, as they mature, one eye migrates to the other side of the head, resulting in the fish living on the seafloor with both eyes facing upward.1

European flounders can grow up to 50 cm (20 inches) long and weigh up to 2.7 kg (6 pounds). They are considered a food and sport fish in Europe. Flounders in the Pleuronectidae family, which includes the European flounder, typically have their eyes and coloring on the right side of their bodies.1
