Description

The three-eye flounder is a flatfish of the family Paralichthyidae from the western Atlantic. The species grows to about 25 cm and has an oval, strongly flattened body with both eyes on the left side. The name refers to three conspicuous dark eyespots on the eyed side, which may distract predators. It inhabits bays, lagoons and shallow coastal waters with soft bottoms, where it hides half-buried. As a bottom ambush predator it seizes passing small invertebrates and small fishes. Owing to its modest size the species is of limited fishery interest and is harmless to humans.
