Description of life cycle and mating behavior Ovoviviparous but aplacental, with 1 to 38 pups. Embryos feed solely on yolk (Ref. 50449). Gestation period ranges from 11-12 months. Newborn and juvenile gummy sharks aggregate in many areas across southern Australia but it is not known whether they inhabit defined shallow-water nursery areas. Ovulation takes place in Oct.-Dec. or Nov.- Feb. (WA). Parturition is complete by the following Dec. (Ref. 6390). The sharks are born at 30-35 cm (Ref. 6871).
