Anablepidae is a family of ray-finned fishes which live in brackish and freshwater habitats from southern Mexico to southern South America.[2] 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
[edit]Fish in the subfamily Oxyzygonectinae are ovoviviparous. The Anablepinae are livebearers. They mate on one side only, right-"handed" males with left-"handed" females and vice versa.[3] 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.
Subfamilies and genera
[edit]The family is divided into two subfamilies and three genera:[4][5][1]
- Anablepinae Bonaparte, 1831
- Oxyzygonectinae Parenti, 1981
- Oxyzygonectes Fowler, 1916
