Flat fish are characterized by a unique body structure that includes a symmetrical shape with both eyes located on one side of the body. This distinctive feature allows them to adapt to their benthic lifestyle, as they often lie flat on the sea floor. This adaptation not only helps them blend in with their surroundings, enhancing their camouflage against predators, but it also facilitates their feeding habits, as they can easily approach prey from below.

In contrast, round fish, such as salmon or tuna, possess a more traditional body shape with a rounded profile and eyes positioned on either side of their heads. Crustaceans, which include species like shrimp and crab, have an entirely different body structure, with jointed limbs and a hard exoskeleton. Mollusks, such as clams and octopuses, also differ significantly, lacking the bilateral symmetry seen in flat fish. Thus, the defining characteristic of flat fish makes them easily distinguishable from these other groups.
