The male was first moved from the aquarium to a small tank, laying it upside-down to keep it calm. Oxygen-rich water was sprayed along its gills, which allowed it to continue to breathe independently. The shark’s sperm was quickly harvested and seen to demonstrate good activity. After the male was released into the aquarium, the female was caught and inseminated, then also returned to the aquarium. Now the team just waits and watches carefully to see if the insemination was successful. When eggs are found in the aquarium, they will be removed and inspected. If they are fertilised, the eggs will be allowed to hatch, undisturbed, behind the scenes, and the young leopard sharks reared.
