Also known as the flatfish order, flatfish, Category:Flatfish

Flatfish are a group of ray-finned fish belonging to the suborder Pleuronectoidei and historically the order Pleuronectiformes (though this is now disputed). Their collective common name is due to their habit of lying on one side of their laterally-compressed body (flattened side-to-side) upon the seafloor; in this position, both eyes lie on the side of the head facing upwards, while the other side of the head and body (the "blind side") lies on the substrate. This loss of symmetry, a unique adaptation in vertebrates, stems from one eye "migrating" towards the other during the juvenile's metam

AI overview

Pleuronectiformes is a group of ray-finned fish commonly known as flatfish, characterized by their flattened bodies and both eyes positioned on the same side of their head as they rest on the seafloor. This unusual adaptation, where one eye migrates during development, represents a unique loss of body symmetry found nowhere else in vertebrates and allows these fish to blend in with their surroundings while hunting prey on the ocean bottom.
