Jenynsia multidentata
Species of fish
From Wikipedia, the free encyclopedia
Jenynsia multidentata is a species of killifish from the family Anablepidae.[1] It is a viviparous, benthopelagic species in the genus Jenynsia. They are onesided livebearers with a clear asymmetry of the males' genitalia. With onset of maturity, the anal fin of male fish develops into a gonopodium which can be brought forward on one side only.[2] Based on the bending to the left or to the right of the tip of the gonopodium, two morphs of male fish can be distinguished.
