“Seventy minutes is a long time to be swimming around with another white shark,” said lead study author Yannis Papastamatiou, a marine scientist at Florida International University.

Often the interactions occurred near a seal breeding ground. “They aren’t working together but being social could be a way to share information,” Papastamatiou said.
