Discover strange 4-eye fish with 360-degree vision

Recently, scientists have discovered the eyes of four-eyed fish named Rhynchohyalus natalensis with a view of up to 360 degrees, making it easy to detect prey or partner as well as hiding enemies.

Researchers at the University of Tübingen (Germany) have discovered an interesting feature of this fish when observing an 18cm Rhynchohyalus natalensis fish caught in the Tasman Sea near New Zealand.

The four-eyed fish Rhynchohyalus natalensis was first discovered in 1924. It usually lives between 800-1000m east of the Atlantic Ocean near Cape Town (South Africa), the Western Atlantic in tropical waters and Western Pacific between Australia and New Zealand.

Four-eyed fish can be observed to detect their prey, enemies or mates from every angle. In the 4 eyes, the 2 main eyes above help the fish observe everything above, 2 oval eyes to help it look down to the bottom and sides of the body.

When light coming from below is focused on its second retina, small reflectors with guaine crystals help to make the eyes of the eyes more spacious. Having a wide view is an advantage of this species when living in a place with great depth.
