Flounder, Flounder fish, Flounder is an ocean dwelling flatfish species that is located off the Canadian and U.S. east coast of the Northern Atlantic, and the Pacific Ocean, in coastal lagoons and estuaries.


Flounder are a flatfish that inhabit ocean waters along the east coast of the United States and Canada. Flounder lie on their left sides on the ocean floor; in adulthood, both eyes are situated on the right, upward-facing side of its body, and are aligned along a roughly 70° angle. Flounder sizes typically vary from five to fifteen inches, though they sometimes grow as long as two feet in length. Their breadth is about one-half of their length. The flounder feeding ground is the soft mud of the sea bottom, near bridge spiles, docks, and other bottom incumbrances; they are sometimes found on bass grounds as well. Their diet consists of fish spawn, mussels and insects.
