Anablepidae
Anablepidae is a family of freshwater and brackish water fishes living in brackish and freshwater habitats from southern Mexico to southern 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''. Fish of this family eat mostly insects and other invertebrates. ==Reproduction== Fish in the subfamily Oxyzygonectinae are ovoviviparous. The Anablepinae are livebearers. Curiously, they mate on one side only, right-"handed" males with left-"handed" females and vice versa.〔(【引用サイトリンク】 Four Eyes and More, the Family Anablepidae )〕 The male has specialized anal rays which are greatly elongated and fused into a tube called a gonopodium associated with the sperm duct which he uses as an intromittent organ to deliver sperm to the female.
