Menage a trois over in 110 seconds and ‘then the males lost all their energy and lay immobile on the bottom’, marine biologist Dr Hugo Lassauce says

A trio of leopard sharks in New Caledonia has made marine science history after they were recorded mating in a “threesome”.

It is the first time the globally endangered species has been documented in a mating sequence, providing valuable knowledge to aid conservation efforts.

Dr Hugo Lassauce, a researcher at the University of the Sunshine Coast, recorded the event while surveying the leopard shark population off the coast of Nouméa.

While snorkelling, he “spotted a female with two males grasping her pectoral fins on the sand below me”.
