The summer flounder, Paralichthys dentatus, is a flatfish native to the western Atlantic Ocean. Known for its ability to change color to blend with its surroundings, this species is a popular target for both commercial and recreational fishing. It typically inhabits sandy or muddy bottoms, where it lies in wait to ambush prey such as small fish and crustaceans. The summer flounder is also recognized for its migration from offshore waters to coastal areas during different seasons.
