Key Differences
Plaice, specifically referred to as European plaice, is characterized by its smooth, dark green skin with conspicuous orange spots and a white underside, thriving mainly in the cold waters of the North Atlantic. Flounder, on the other hand, represents a broader category of flatfish species, with members inhabiting oceans around the globe, varying greatly in color and habitat.
In terms of culinary use, plaice is highly valued for its sweet, mild flavor and fine, flaky texture, making it a popular choice in European cuisine. Flounder, while also appreciated for its taste, includes a variety of species such as the summer flounder (fluke) and the winter flounder, each with its unique culinary qualities and textures.
Plaice typically prefers sandy or muddy sea bottoms and is found at depths ranging from shallow waters to up to 200 meters. Flounder species adapt to a wide range of habitats, from estuarine areas to deep sea environments, displaying a remarkable ability to camouflage with their surroundings.
Reproduction and life cycle aspects also distinguish plaice from many flounder species. Plaice engage in a seasonal migration to spawn, laying eggs in specific areas that offer protection and suitable conditions for the offspring. Flounders, depending on the species, may have varied spawning behaviors and locations, often related to temperature and salinity conditions of their habitats.
Despite these differences, both plaice and flounder share common features typical of flatfish: a laterally compressed body, both eyes on one side of the head after metamorphosis, and a bottom-dwelling lifestyle, making them fascinating subjects of study for marine biologists and a prized catch for fishermen.
