what type of fish is flounder

Flounder is a type of flatfish —a bottom-dwelling, laterally flattened fish in the order Pleuronectiformes.

Quick Scoop

  • Flounder isn’t a single species but a group of flatfish species found in oceans around the world.
  • They are demersal fish, meaning they live on or near the seafloor, often buried or lying flat on sediments.
  • Flounders belong mainly to several flatfish families: Achiropsettidae, Pleuronectidae, Paralichthyidae, and Bothidae.
  • A classic flounder body is thin and oval, with both eyes on one side of the head, helping it camouflage on the bottom.
  • In cooking and seafood markets, “flounder” usually refers to any of these mild, flaky white flatfish sold under that name.

Tiny Story-style explanation

Imagine a young, normal-looking fish swimming upright with an eye on each side. As it grows, one eye slowly migrates to the other side of its head, and the fish begins to live lying flat on the seafloor like a living rug, blending into the sand. That “one-sided” seafloor ambush predator you end up seeing on a dinner plate as mild, white fillets is what we call a flounder, a flatfish from the order Pleuronectiformes.
