Open encyclopedia reference
Jenynsia multidentata is a species of killifish from the family Anablepidae. 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. 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.
