There is no proper information about the reproduction habits of the Goblin shark. No pregnant female has been found or captured. It is believed that they are ovoviviparous, meaning that the young are born live, but there is no placental connection, instead the embryos are nourished by egg yolk. There is no real information of when the Goblin shark matures, when and how it mates, and how long the gestation period lasts.
