A 19th century illustration of the 'double-eyed' fish Anableps Tetraopthalmus / Anableps Anableps, the largescale four-eyes. The minnow-like fish is a species of four-eyed fish found in fresh and brackish waters of northern South America and Trinidad. Though does not actually have four eyes, each eye is split into two lobes by a horizontal band of tissue, each with its own pupil and separate vision allowing it to see above and below the surface of the water at the same time.
