The white-eye, Oxyzygonectes dovii, is a species of killifish of the family Anablepidae. This species is the only member of its genus Oxyzygonectes and the subfamily Oxyzygonectinae.[1]

This fish species is found in Pacific drainages in Nicaragua, Costa Rica, and Panama.[1]

Many of these fish inhabit brackish waters. They are found in rivers of low elevation, up to 15 metres (50 ft) above sea level. These fish feed on detritus, algae, and sometimes on terrestrial insects.[2]
