Although information about its movements is limited by the rarity of the white shark, some data has been gathered through tag-and-release programs in the United States, South Africa and Australia. These studies reveal that the white shark is capable of making movements on localized, regional and intercontinental scales. Generally, larger individuals undertake long journeys across the great ocean basins. Observations of two white sharks cruising in open water, apparently not feeding, revealed a strong tendency to ascend and descend slowly and steadily. The white shark is also capable of short, high-speed pursuits and even launching itself clear from the surface. Patterns in movement and abundance within some areas appear to be linked with seasonal variations in surface temperature. However, this may only have a minimal effect on the distribution of the white shark.
