Gulf Flounder
Three dark, eyelike spots arranged in a triangle on its body set the Gulf Flounder apart from every other flatfish in its range — a useful field mark for a species that otherwise disappears completely against sand, shell, and hard bottom.
It ranges from the western Atlantic coast through the Gulf of Mexico and into the Caribbean, with its center of abundance along the northeastern Gulf.
Most anglers who target it are as motivated by the table as by the fishing — its white, delicate flesh is among the best eating in inshore saltwater.
Scientific Name: Paralichthys albigutta
- Three prominent dark, eyelike (ocellated) spots arranged in a triangle — one on the lateral line, one above, one below — are the defining mark; Southern Flounder lacks these spots entirely, and Summer Flounder carries five or more.
- Color shifts actively from near-white to tan to dark brown to match the bottom; the camouflage is convincing enough that the spots are often the only reliable way to confirm the ID in hand.
- Wedge-shaped tail with the tip centered, strong canine-like teeth, and a left-eyed body plan shared with its close relatives in the genus.
- Common size is around 14 inches and 2 pounds; the species tops out near 28 inches and just over 6 pounds — the smallest of the common flounder in its range.
What to know
Habitat Distribution
- A subtropical flatfish of the western Atlantic, ranging from the Carolinas south through Florida, across the Gulf of Mexico, and into the Caribbean as far as Colombia; most abundant along the northeastern Gulf coast and scarce west of the Mississippi River delta.
- Bays, lagoons, and shallow coastal waters over hard and sandy bottoms are its core habitat; the continental shelf at roughly 60–300 feet holds adults, while estuaries and tidal creeks serve as seasonal feeding and nursery grounds.
- Juveniles settle into high-salinity seagrass beds to grow; adults use limestone ledges, structured reef areas, and flat hard-bottom zones as well as open sand.
Specific Spots
- Hard-bottom transitions — where sand gives way to oyster shell, limestone ledge, or nearshore reef — are the most reliable holding areas; the edge itself is where flounder position to intercept prey moving between bottom types.
- Tidal creek mouths and estuary passes concentrate fish during the fall outmigration, when moving water funnels shrimp and baitfish through a narrow zone and flounder stack up on the downstream side.
- Riprap banks and bridge pilings create current breaks and shade that hold bait; flounder press tight to the base of the structure rather than suspending away from it.
Gulf Flounder FAQ
Answers from onWater's species guide.
What are the best lures and bait for Gulf Flounder?
Bucktail jigs tipped with scented soft plastics, Gulp! shrimp, paddle tails, or curly-tail grubs, are the workhorse artificial setup; drag them slowly along the bottom with pauses, keeping contact with the seafloor throughout the retrieve.
What do Gulf Flounder eat?
Shrimp and crabs are the primary forage, live or fresh-dead shrimp on a bottom rig is the most consistent producer because it matches what flounder are already keyed on, and the slow, natural movement keeps the bait in the strike zone where a lunge is possible.
Where do Gulf Flounder live?
A subtropical flatfish of the western Atlantic, ranging from the Carolinas south through Florida, across the Gulf of Mexico, and into the Caribbean as far as Colombia; most abundant along the northeastern Gulf coast and scarce west of the Mississippi River delta.
