Marine biologists have recorded the first-ever documented mating of leopard sharks in the wild, involving a threesome off the coast of Nouméa, New Caledonia. The event, captured by Dr Hugo Lassauce from the University of the Sunshine Coast, provides crucial insights into the reproductive behaviour of this globally endangered species.
Dr Lassauce observed the encounter while snorkelling, noting that two males sequentially grasped a female's pectoral fins. The entire mating sequence lasted just 110 seconds, with the first male finishing in 63 seconds and the second in 47 seconds. Afterward, the males lay immobile on the seabed while the female swam away.
Published in the Journal of Ethology, the study highlights the rarity of such observations. Dr Christine Dudgeon, a marine ecology expert, noted that the footage suggests the area is a critical mating habitat, which could inform conservation strategies and artificial insemination research aimed at rewilding the species.
Dr Lassauce emphasised that reproductive behaviour in wild sharks is largely undocumented, unlike in dolphins. The discovery underscores the importance of protecting these habitats to support the recovery of leopard shark populations.
