Species often confused with {name}
Gulf Flounder
Paralichthys albigutta
Key differences: Typically 'right-eyed' (dextral), though some can be reversed. Possesses three prominent, ocellated (eye-like) spots forming a triangle on the eyed side of the body. These spots are usually darker than the surrounding body color and often have a pale halo.
Summer Flounder
Paralichthys dentatus
Key differences: Typically 'left-eyed' (levo-ocular), similar to Southern Flounder. However, Summer Flounder usually has 5-14 distinct, dark, ocellated spots (not always eye-like, but distinct dark spots) scattered over the body, which are generally larger and more numerous than any markings on a Southern Flounder. The body is also often more elongated.
Fringed Flounder
Etropus crossotus
Key differences: Much smaller species, typically not exceeding 8 inches. Has a more rounded body shape and a smaller mouth. The lateral line is less arched, and it lacks the large teeth of Paralichthys species.
