Like other houndsharks, the whiskery shark is [[viviparous]]; the developing [[embryo]]s are sustained by [[yolk]] and probably also maternally produced [[histotroph]].<ref name="last and stevens"/> Males can mate every year, while females have a biennial reproductive cycle. [[Mating]] takes place in August and September; females store [[sperm]] until late January to early April of the following year, when the [[ovum|ova]] are ready to be [[ovulation|ovulated]] into the [[uterus]]. After a 7– to 9-month-long [[gestation period]], litters of four to 28 (average 19) pups are born between August and October. The litter size increases with the size of the female.
