Thousands of Port Jackson Sharks Discovered Sleeping on Ocean Floor

Researchers find a massive gathering of female sharks in Australia's Beagle Marine Park, raising new ecological questions.

The sharks were found 213 feet below the surface, packed tightly like a carpet.
This is the second time researchers have observed this phenomenon in six years.
Only female sharks were present, leading scientists to speculate on the reasons.
Port Jackson sharks are nocturnal hunters and not considered a threat to humans.
The findings highlight the ecological significance of Beagle Marine Park.
