What’s the Difference Between Fluke and Flounder?

First, we need to mention that Fluke and Flounder are the same species. Fluke is just another name for Summer Flounder, which is a large Flatfish that is most commonly found in the North Atlantic.

• Summer Flounder (Fluke)
• Winter Flounder

The most significant reason anglers get confused is that Winter Flounder also lives in the same environment. However, there are some easy ways that you can tell these two fish apart from one another.

When Summer Flounder is facing up, their mouth will point up. On the other hand, Winter Flounder will have their mouth pointing up when they’re facing right. Color is another indicator. Summer Flounder is a light brown color, and Winter Flounder is typically a much darker brown color.

Very adapted to life on the bottom of the ocean, a Flounder’s eyes will move location as they age until, eventually, both eyes end up on the same side of their face. Fluke are left facing, and Winter Flounder are right facing.

While it’s easy to identify them when you’re holding one in your hand, identifying them by which way they face while they’re underwater can be a lot more complicated. When underwater, Winter Flounder can appear almost black because of their darker coloring. It’s how they got their common nickname, Blackback. The whitish spots on Summer Flounder, along with their lighter coloring, are a more precise indicator of which species you’re looking at. However, coloring can be influenced by the environment they live in, so their faces are always a 100% way to identify the different Flatfish from one another.

Flounder Distribution

Although Flounder is the common name that refers to almost all demersal Flatfish (fish that live at or near the bottom of the ocean), it’s not technically correct. The four main species commonly called Flounder are Gulf Flounder, Southern Flounder, Summer Flounder (also known as Fluke), and Winter Flounder.

Although similar, they are, in fact, different. Simply calling all of these fish flounder would be like calling all species of Tuna just Tuna when there are some significant differences between Bluefin Tuna and Yellowfin Tuna. Luckily, the location you’re fishing in plays an essential role in what type of Flounder you’re most likely to catch. So, telling the difference between the Summer and Winter Flounder isn’t as hard as you think.

You’re most likely to catch Summer Flounder along the Gulf of Mexico and up into the Atlantic all the way through to Southern Maryland. Northern Flounder or Fluke can be seen in the Carolinas, but they’re going to be a lot more common well north of Chesapeake Bay.

Both species of Flounder aren’t afraid of shallow water, sometimes creeping right up into shallow bays at night when they feel most safe from predators. In some parts of the world, including Australia and New Zealand, Flounder are commonly speared of at night in highly shallow water using an underwater light and wading around in sandy bays on very calm and still nights where the eyes of the Flounder makes them easier to spot despite their excellent camouflage.

Despite their odd appearance and a lot of bones, Flounder truly is a delicious fish to eat and is often served whole. Their white fleshy fish is sweet and succulent and well worth a fishing trip to catch a few of these tasty fish. However, before you hit the water, be sure to check the local regulations for size, season, and bag limits, along with the allowed method of take.
