Naked Sole

The naked sole is a small flatfish in the family Achiridae (American soles), found along the Atlantic coast of North America, primarily in the western Atlantic and Gulf of Mexico. It gets its common name from its scaleless, smooth-skinned body, which contrasts with the rougher, scaled skin typical of many other soles. The species is right-eyed and lives on sandy seafloor in coastal and shelf waters. Naked sole are small compared to many other flatfish and are more frequently encountered in scientific trawl surveys than in general observation, owing to their cryptic coloration and preference for burying in sand.

• Small, oval body, right-eyed, with no scales—smooth to the touch
• Upper side is pale tan to grayish-brown with numerous fine, dark, wavy crossbands or striping
• Underside is plain white
• Small eyes set close together
• Pectoral fins reduced or absent on the eyed side in some individuals
• Adults typically reach 10-18 cm

Its scaleless skin and fine banded pattern distinguish it from the similar fringed sole, which shows a coarser, more fringed fin margin, and from larger, scaled soles found in the same waters. The tight, wavy crossbanding is generally more numerous and closely spaced than the striping seen on related species.

Naked sole are found along the western Atlantic coast of North America, from around the Carolinas south through Florida and into the Gulf of Mexico. They inhabit sandy seafloor of the inner and outer continental shelf, typically at depths from around 10 to 100 meters. The species favors clean, well-sorted sand where its fine banded pattern provides effective camouflage, and it is generally absent from muddy or heavily silted bottoms. Because it burrows readily and stays close to the substrate, it tends to be more common on open, current-swept sand flats than in sheltered, sediment-choked coastal habitat.

Naked sole are small, secretive bottom-dwellers that spend much of their time partially buried in sand, relying on camouflage rather than speed to avoid predators. They feed on small benthic invertebrates, including tiny crustaceans and worms found in or on the sand surface. Due to their small size and burrowing habit, they are rarely observed by casual divers and are more commonly documented through scientific trawl sampling. Reproduction follows the typical flatfish pattern, with pelagic eggs and larvae that drift before settling and metamorphosing into the flattened juvenile form on the seafloor.
