Achiridae
The American soles are a family (biology), family (Achiridae) of flatfish occurring in both freshwater and Marine (ocean), marine environments of the Americas. The family includes about 35 species in seven genera. These are closely related to the Soleidae, soles (Soleidae), and have been classified as a subfamily of it, but achirids have a number of distinct characteristics. Eyes are on the right side, and the eyed-side lower lip has a distinctive fleshy rim. The dorsal fin, dorsal and anal fins are usually separate from the caudal fin. The pectoral fins are small or nonexistent. They are fairly small; only ''Achirus achirus'' is known to surpass in length.

Flatfish
A flatfish is a member of the Ray-finned fish, ray-finned demersal fish Order (biology), suborder Pleuronectoidei, also called the Heterosomata. In many species, both eyes lie on one side of the head, one or the other migrating through or around the head during development. Some species face their left sides upward, some face their right sides upward, and others face either side upward. The most primitive members of the group, the Threadfin, threadfins, do not resemble the flatfish but are their closest relatives. Many important food fish are in this order, including the flounders, sole (fish), soles, turbot, plaice, and halibut. Some flatfish can camouflage themselves on the ocean floor. Taxonomy Due to their highly distinctive morphology, flatfishes were previously treated as belonging to their own order, Pleuronectiformes. However, more recent taxonomic studies have found them to group within a diverse group of nektonic marine fishes known as the Carangiformes, which also inc ...
