Anableps anableps, the largescale four-eyed fish is a species of four-eyed fish found in fresh and brackish waters of northern South America and Trinidad. This species grows to a length of 32 centimetres (13 in) TL. This fish can be found in the aquarium trade. The fish does not actually have four eyes, but instead each eye is split into two lobes by a horizontal band of tissue, with each lobe having its own pupil and separate vision. This allows the fish to see under and above the surface of the water at the same time.
