Sharknado: The All-Girl Edition!

Forget your typical girl sleepovers with onesies and face masks. This one’s got teeth—literally! Scientists have just discovered an all-girl shark sleepover in Australia’s Beagle Marine Park!

Port Jackson sharks, known for their snouts and radial neck creases, layered the sea floor in a ‘very cutesy, very demure’ slumber party, like a scene straight out of a Jaws remake for chicks only. This bizarre event was caught on camera by an underwater robot from the South Australian Research and Development Institute.

“A spectacular scene was relayed to us by a remotely operated vehicle equipped with seven cameras that was custom built by Boxfish Robotics in collaboration with [the University of Tasmania Institute for Marine and Antarctic Studies]," said Jacquomo Monk, the research team leader, in a statement. "There were thousands of sharks tightly packed like a carpet spread across the seafloor.”

‘Girls just wanna have fun': Watch all-girl shark slumber party

Six years ago, researchers first spotted the sharks during a survey of the park. The team returned for a two-week follow-up, led by the Institute for Marine and Antarctic Studies, IMAS, to see how things had changed.

The research is funded by the Australian Government’s National Environmental Science Program and supported by a "grant of sea time from the Southern Australian Coastal Research Vessel Fleet with National Collaborative Research Infrastructure Strategy funding."

The findings will be handed over to park managers to assess conservation goals.

What are Port Jackson sharks?

The sharks are medium-sized, between 4.5 to 5.5 feet long. Native to Australia, they’re mostly used for science or accidental fishing bycatch, according to the Florida Museum.

Recent studies show concerns over high embryonic mortality rates, highlighting the need to monitor fishing impacts on population numbers.

These night owls rest during the day and hunt animals, like squid, at night, as per the study’s release. And while there are no reports of Port Jackson sharks attacking humans, they can potentially be harmful if provoked.

‘More questions than answers': All-female slumber party stumps scientists

Monk hoped to find the sharks again, reinforcing the park’s importance to these creatures.

“Coming upon them twice in a 3000-square-kilometre park is like finding a needle in a haystack," said Monk in a statement. “It was very exciting when we managed to traverse over a rise in the reef to get a glimpse of the sharks snoozing 65-metres below the vessel in almost the same location as they were six years ago."

The all-female party is puzzling scientists.

“This poses more questions than answers for us, but we know that the males and females of this species often live apart, except when mating," said Monk. "We don’t know exactly why the females are here. Perhaps they are feasting on the local delicacy – doughboy scallops – before the long trip north to lay their eggs."
