Anablepidae

Encyclopedia : A : AN : ANA : Anablepidae

Anablepidae is a family of freshwater and brackish water fishes living on river estuaries in Central and South America. There are three genera with sixteen species: the four-eyed fishes (genus Anableps), the onesided livebearers (genus Jenynsia) and the white-eye, Oxyzygonectes dovii.

They bear live young, and, curiously, only mate on one side, right-"handed" males with left-"handed" females and vice versa [link]. They eat mostly insects and other invertebrates, and are sold in some pet stores as pet fish.

The four-eyed fishes 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.
