The flounder is a unique flatfish that is well known for having both eyes on one side of it’s head as an adult. Many believe the fish is born this way, but they actually are born with eyes on both sides and then as the fish matures one eye migrates so they both end up on the same side.
These fish are found on the bottom where their camouflage coloring on one side, flat body, and eyes on one side make them the perfect bottom dweller. There are many types of flounder around the world, but the Southern Flounder that are caught by Fly Fish Rockport are also known as left eye flounder, as their “up” side or side with both eyes, is always the left side of the fish.
An additional unique feature of the Southern Flounder is that they lack a swim bladder, which makes it easy for them to maintain their position on the ocean bottom.
