Description

The deepwater flounder is a flatfish of the lefteye flounder family (Bothidae) from the western Atlantic. The species grows to about 18 cm and has a strikingly elongate, thin, strongly flattened body with both eyes on the left side, unusual for a flatfish. It lives on soft bottoms of the continental shelf and slope at considerable depth. As a bottom hunter it feeds on small benthic invertebrates. The mottled eyed side provides camouflage on the sea floor. Owing to its deep habits the species is rarely seen and is harmless to humans.
