Do you know the four eyed fish?

Image of Four eyed fish from Google.
Anableps, a fish looks like it has four eyes. But it only has two eyes. Only the south Americans and Mexicans are fortunate to have seen the fish as it frequents the rivers and estuaries from southern Mexico to northern South America.

They have eyes raised above the top of the head and divided in two different parts, so that they can see below and above the water surface at the same time.

The top half is for seeing in the air; the bottom half is for underwater.
