Family Anablepidae, three genera, thirteen species, fresh, brackish and marine. The monotypic Oxyzygonectes is oviparous, the other genera/species are "one-sided" livebearers. Mmm, talk about odd ball fishes... Being able to see and make sense out of four different optical fields of view simultaneously? Being livebearers that can/do only mate on one side, right-"handed" males with left-"handed" females and vice versa? Umm, the Anableps can live on land, moist for extended periods of time... tend to travel in schools... The family is known in the sciences as "the four-eyes, one-sided livebearers and white-eye"... I rest my case. Distribution: Southern Mexico to the end of South America. Subfamily Anablepinae, Genus Anableps, three species. Benefit from some salt in their environment, live foods, frequent water changes. Used in eye research. Will eat small fishes.
Subfamily Jenynsiinae
