Marine biologist Hugo Lasso from the University of the Sunshine Coast in Australia has witnessed and captured on video a groundbreaking event: the first-ever documented instance of zebra sharks (Stegostoma tigrinum) mating in the wild, which included group sex. The Guardian reports this unprecedented observation.
Zebra Sharks Mating: First Wild Group Sex Observed
Off the coast of New Caledonia, Lasso observed one female zebra shark with two males, who were holding onto her pectoral fins. After an hour of observation, the mating began, lasting a total of 110 seconds. The first male copulated with the female for 63 seconds, followed by the second male for 47 seconds. Afterward, both males appeared exhausted and sank to the seabed, while the female quickly swam away.
While group mating has been recorded in other shark species, the reproduction of these predators in their natural habitat remains largely unstudied.
This observation holds immense scientific and ecological significance, especially since zebra sharks are an endangered species. The video captured by Lasso could serve as a crucial foundation for developing new conservation strategies and furthering research into artificial insemination efforts aimed at preserving the species.
