Researchers on an expedition to Beagle Marine Park, Australia, stumbled across a blanket of thousands of sleepy Port Jackson sharks snoozing on the seabed.
Back in 29024 scientists from the University of Tasmania Institute for Marine and Antarctic Studies (IMAS) captured stunning footage of the dozing sharks from an underwater robot that had been deployed from the South Australian Research and Development Institute (SARDI) research vessel MRV Ngerin.
“There were thousands of sharks tightly packed like a carpet spread across the seafloor,” says voyage leader, Dr Jacquomo Monk of IMAS. Surprisingly, the sharks were all females.
“One of the interesting things we discovered this time is that the Beagle gathering appears to be only for females,” Dr Monk says.
