by Hundreds of hammerhead sharks gather around an ancient volcano in the Pacific Ocean, drawn by secret signals radiating from the seabed, a new clip reveals.
The footage, which features in the third episode of Netflix's new wildlife documentary series "Our Living World," shows a school of hammerhead sharks (Sphyrnidae) circling Cocos Island — a volcanic island in the eastern tropical Pacific about 310 miles (500 kilometers) southwest of mainland Costa Rica.
Cocos Island is a known haven for endangered hammerhead sharks, but scientists still aren't sure how and why so many sharks navigate across swathes of ocean to convene there every year.
