Scientists are developing an artificial uterus to help save the endangered grey nurse shark whose pups engage in a spot of cannibalism.
While still in the womb the strongest will devour their weaker siblings meaning only two can be born from each female at a time.
The research has been funded by the New South Wales department of Primary Industries in a desperate bid to save the species, acknowledged as one of the most threatened in the waters of eastern Australia.
Dr Nick Otway, who is leading the research estimates that fewer than 1000 grey nurse sharks of optimum breeding age are left in the wild in Australian waters.
It is hoped the man-made womb will help in an artificial breeding program
Check out the cannibals in action.
