Major space-use hotspots of tracked pelagic sharks in the Atlantic Ocean were in the Gulf Stream and its western approaches, the Caribbean Sea, the Gulf of Mexico and around oceanic islands such as the Azores. In the Indian Ocean, space-use hotspots were evident in the Agulhas Current, Mozambique Channel, the South Australian Basin and northwest Australia, and in the Pacific Ocean, space-use hotspots were in the California Current, Galapagos Islands and around New Zealand.

Although, as expected, tagging sites occurred in some space use hotspots (as tagging rates are inherently higher in hotspots), the authors also identified space-use hotspots in which no tagging sites occurred in the North Atlantic Ocean (outer Gulf Stream, Charlie Gibbs Fracture Zone, western European shelf edge and the Bay of Biscay), the Indian Ocean (southern Madagascar, the Crozet and Amsterdam Islands, and the South Australian Basin) and the Pacific Ocean (Alaska Current, outer California Current, the white shark ‘café’ area, halfway between Baja California and Hawaii, North Equatorial Current, Clipperton Island and Kermadec Islands)
