Conservation
Although listed as "Least Concern" on the World Conservation Union (IUCN) Red List, it is known that the shark's embryos experience very high mortality rates (89%). Its status is otherwise, largely unknown. Predators of the species are also unknown. Though Crested bullhead shark (Heterodontus galeatus) are known to prey upon Jackson shark embryos, the biggest threat is probably from other sharks such as white sharks and the broadnose sevengill shark (Notorynchus cepedianus).
