The fins are only used for balance. Drift-diving data provided the final clue to the research team: they established that migrating sharks lost buoyancy over time.

Our mission is to explore, explain, and sustain life. Each year, great white sharks that forage in waters off the central California coast migrate as much as 2,500 miles (4,000 km) over the open ocean, to other feeding grounds in the Pacific Ocean. Miss Costa, a great white shark, was tracked in the Gulf of Mexico off the Florida panhandle in the Spring of 2019. Sharks store oil before migration (making them float) then gradually use that energy throughout their journey (making them sink). In 2009, NOAA added the large sharks to their “species of concern” program and also asked for the public’s help  with a little bit of citizen science: spot the basking shark! Great white sharks also need a way to store energy during their long migrations, but until recently, this specific mechanism was unknown. Burney J.
