Tonguefish are flatfish with elongated, tongue-shaped bodies, belonging to the family Cynoglossidae. They are masters of disguise, blending seamlessly with the sandy or muddy bottoms they inhabit. Both eyes are located on one side of their body, an adaptation for their bottom-dwelling lifestyle. These fish are typically found in tropical and subtropical waters. Think of them as the chameleons of the sea floor, always ready to vanish into their surroundings. They feed on small invertebrates and are an important part of the marine ecosystem.
