Difference Between Fluke and Flounder

Fluke and flounder are terms often used interchangeably to describe flatfish, but they belong to different families. Flukes, also known as summer flounder, belong to the family Paralichthyidae, characterized by their large, asymmetrical bodies with both eyes situated on one side as they mature. In contrast, flounders are part of several families, including Bothidae and Pleuronectidae, and may have a more symmetrical appearance, with less pronounced asymmetry in adult forms.

Both fish are adept at camouflaging themselves on the ocean floor, changing colors to match their surroundings. However, flukes typically have a smoother texture and lighter coloration compared to some flounder species, which can display a variety of colors and patterns to blend into different seabed environments.

In terms of habitat, flukes are commonly found in the Atlantic Ocean, from the North Carolina coast up to Maine, preferring warmer waters. Flounders have a broader range, inhabiting both the Atlantic and Pacific Oceans, and can be found in a variety of water temperatures, from cold northern waters to warmer southern seas.

Culinary differences also exist between the two. Flukes are highly prized for their lean, white flesh, which is delicate in flavor and texture, making them a favorite among seafood enthusiasts. Flounders, while also enjoyed for their taste, can vary more in texture and flavor depending on the species, with some being firmer and others more delicate.

Despite these differences, both flukes and flounders are popular targets for recreational and commercial fishermen due to their taste and the challenge of flatfish fishing, which requires specialized techniques to effectively catch these bottom-dwelling creatures.
