Paralichthys lethostigma, the southern flounder, is a species of large-tooth flounder native to the East Coast of the United States and the northern Gulf of Mexico. It is a popular sport fish and is the largest and most commercially valuable flounder in the western North Atlantic Ocean and Gulf of Mexico. It is a "left-eyed flounder", meaning the left side is pigmented and is the "up side".
