Annika is a greater than 15 feet long female white shark. She was first photographed at Guadalupe Island, Mexico in 2009. She was tagged with a SPOT tag in 2009 which tracks her movements in real time. The tracking data shows that she visits Guadalupe Island between October and January, and then makes a two year migration, spending up to 16 months in the middle of the Pacific Ocean before traveling to the Pacific coast of Baja California for the months of June and July, presumably to give birth. This two year migration is linked to an estimated 18 month gestation cycle and the visit to the Mexican coast corresponds with the known pupping season for newborn (or young-of -the-year) white sharks.
This map shows 3.5 years of tracking data for Annika.
