Description of life cycle and mating behavior Ovoviviparous. Sexes can be readily distinguished by the male's intromittent organ and the female's genital pore (Ref. 240, 205). On the basis of this morphology, copulation may involve flexion of the male's body and pumping of sperm into the female (Ref. 240). Embryos are retained in the ovaries until about 6 mm long, deriving nourishment from large yolk sacs, making the species ovoviviparous rather than viviparous (Ref. 240).
