True solesSoleidae

True soles are benthic flatfish with strongly flattened, oval to elongated bodies. Adults have both eyes positioned on the right side of the head, typically resting on their blind (left) side on the seabed. Their cryptic, mottled brown and grey coloration provides effective camouflage with sandy or muddy substrates. Most species are small, generally reaching 10-30 cm (4-12 in) in length. The common name "sole" derives from the Latin "solea," referring to a sandal, a description of their flattened shape.

These flatfish inhabit shallow coastal waters, seagrass beds, and sandy bottoms down to depths of 50 m (165 ft). Primarily ambush predators, they consume small invertebrates, particularly crustaceans. Soles bury themselves quickly into the substrate when disturbed, making them challenging for divers to spot.
