Female sharks can store sperm for up to a year before using it to fertilise their eggs.

Although sperm storage is common in sharks – it’s a handy trick that means that females can fertilise their eggs even if they’re not ovulating at the time of mating – generally long-term storage is known to stretch from 13 to 28 months.
