Description
The foureyed rockskipper is a small bottom fish of the scaled blenny family (Labrisomidae) from the eastern Pacific, famous for its peculiar eyes. The species grows to about 11 cm and has an elongate body with a large head. It lives in the intertidal zone, where it actively shuttles back and forth between rock pools and out of water on rocks. Notably each eye is divided in two by a vertical band, with separate corneal halves that allow it to see sharply both in air and underwater - an adaptation to its amphibious way of life. As a hunter it feeds on small crustaceans and invertebrates. The species is harmless to humans.
