Tiger Mind Maps

A new study by University of Hawaii researchers suggests tiger sharks may use mental maps and calendars to guide their migrations as they search for food.

The study used satellite tags to track sharks at French Frigate Shoals in the Papahanaumokuakea Marine National Monument.

Researchers led by Carl Meyer of the Hawaii Institute of Marine Biology found some tiger sharks stayed at the atoll year-round.

Others visited in the summer to feed on fledgling albatross but then migrated to other spots along the Hawaiian islands or to the open ocean.

The study was designed to develop a better understanding of long-term movement patterns of sharks in the monument.

The study appears in the journal Marine Biology.
