Do Any Real-Life Fish Actually Have No Eyes?

Believe it or not, there are some fish species in the world that do not have eyes. Most of these fish live in the deepest parts of the ocean or in caves where it is dark and there is no need for eyesight.

One example is a North American freshwater catfish known as the Mexican blindcat. This tiny little, pink fish barely grows more than 3 inches, lives in caves and wells, and has no eyes!
