Jenynsia is a genus of freshwater fishes in the family Anablepidae.
Like Anableps species, they are onesided livebearers: some sources indicate that they only mate on one side, right-"handed" males with left-"handed" females and vice versa.
However other sources dispute this.
These South American fish are viviparous.
