For the first time, the movements of a wild hammerhead shark were tracked for a period of 10.5 months.

The movements of a scalloped hammerhead shark were monitored over a period of 10.5 months as it swam 2,082 miles (3,350 kilometers) in the Gulf of California. The shark likely swam in a school of fellow hammerheads at offshore islands and underwater volcanoes called seamounts during the day, but dived to greater depths at night to feed on fish and squid.
